chore: narrow invocation work into unify pipeline proposal

* feat: add support for Pi (pi.dev) coding agent

Add Pi as a supported tool in OpenSpec with full adapter implementation.

Changes:
- Create pi.ts adapter for command generation
- Register adapter in registry and export from index
- Add Pi to AI_TOOLS config with .pi skills directory
- Add tests for piAdapter following existing patterns
- Update supported-tools.md documentation

Pi uses:
- Skills: .pi/skills/ (Agent Skills standard)
- Prompts: .pi/prompts/*.md (with description frontmatter)

Closes #732

* fix: add Pi to LEGACY_SLASH_COMMAND_PATHS for test compliance

* style: add trailing newline to pi.ts

* fix: correct legacy cleanup pattern for Pi (opsx-*.md not openspec-*.md)

* fix: add YAML escaping for Pi adapter to handle special characters in descriptions

- Add escapeYamlValue() function to properly escape YAML special characters
- Apply escaping to description field in frontmatter
- Add tests for YAML special character escaping (colons, quotes, newlines)

This follows the same pattern used by cursor, claude, and windsurf adapters.

* fix: remove Pi from LEGACY_SLASH_COMMAND_PATHS

Pi was never supported in pre-1.0 versions, so no legacy cleanup is needed.
Per reviewer feedback: this is only for tools from pre-1.0 OpenSpec.

* test: relax legacy-cleanup registry coverage invariant

+# Changesets
 
-- Add a changeset locally with `pnpm changeset`.
-- The CI "Release (prepare)" workflow opens/updates a Version Packages PR.
-- Publishing happens from a GitHub Release via the "Publish to npm" workflow.
+This directory is managed by [Changesets](https://github.com/changesets/changesets).
 
+## Quick Start
+
+```bash
+pnpm changeset
+```
+
+Follow the prompts to select version bump type and describe your changes.
+
+## Workflow
+
+1. **Add a changeset** — Run `pnpm changeset` locally before or after your PR
+2. **Version PR** — CI opens/updates a "Version Packages" PR when changesets merge to main
+3. **Release** — Merging the Version PR triggers npm publish and GitHub Release
+
+> **Note:** Contributors only need to run `pnpm changeset`. Versioning (`changeset version`) and publishing happen automatically in CI.
+
+## Template
+
+Use this structure for your changeset content:
+
+```markdown
+---
+"@fission-ai/openspec": patch
+---
+
+### New Features
+
+- **Feature name** — What users can now do
+
+### Bug Fixes
+
+- Fixed issue where X happened when Y
+
+### Breaking Changes
+
+- `oldMethod()` has been removed, use `newMethod()` instead
+
+### Deprecations
+
+- `legacyOption` is deprecated and will be removed in v2.0
+
+### Other
+
+- Internal refactoring of X for better performance
+```
+
+Include only the sections relevant to your change.
+
+## Version Bump Guide
+
+| Type | When to use | Example |
+|------|-------------|---------|
+| `patch` | Bug fixes, small improvements | Fixed crash when config missing |
+| `minor` | New features, non-breaking additions | Added `--verbose` flag |
+| `major` | Breaking changes, removed features | Renamed `init` to `setup` |
+
+## When to Create a Changeset
+
+**Create one for:**
+- New features or commands
+- Bug fixes that affect users
+- Breaking changes or deprecations
+- Performance improvements users would notice
+
+**Skip for:**
+- Documentation-only changes
+- Test additions/fixes
+- Internal refactoring with no user impact
+- CI/tooling changes
+
+## Writing Good Descriptions
+
+**Do:** Write for users, not developers
+```markdown
+- **Shell completions** — Tab completion now available for Bash, Fish, and PowerShell
+```
+
+**Don't:** Write implementation details
+```markdown
+- Added ShellCompletionGenerator class with Bash/Fish/PowerShell subclasses
+```
+
+**Do:** Explain the impact
+```markdown
+- Fixed config loading to respect `XDG_CONFIG_HOME` on Linux
+```
+
+**Don't:** Just reference the fix
+```markdown
+- Fixed #123
+```

+## 1.1.1
+
+### Patch Changes
+
+- [#627](https://github.com/Fission-AI/OpenSpec/pull/627) [`afb73cf`](https://github.com/Fission-AI/OpenSpec/commit/afb73cf9ec59c6f8b26d0c538c0218c203ba3c56) Thanks [@TabishB](https://github.com/TabishB)! - ### Bug Fixes
+
+  - **OpenCode command references** — Command references in generated files now use the correct `/opsx-` hyphen format instead of `/opsx:` colon format, ensuring commands work properly in OpenCode
+
+## 1.1.0
+
+### Minor Changes
+
+- [#625](https://github.com/Fission-AI/OpenSpec/pull/625) [`53081fb`](https://github.com/Fission-AI/OpenSpec/commit/53081fb2a26ec66d2950ae0474b9a56cbc5b5a76) Thanks [@TabishB](https://github.com/TabishB)! - ### Bug Fixes
+
+  - **Codex global path support** — Codex adapter now resolves global paths correctly, fixing workflow file generation when run outside the project directory (#622)
+  - **Archive operations on cross-device or restricted paths** — Archive now falls back to copy+remove when rename fails with EPERM or EXDEV errors, fixing failures on networked/external drives (#605)
+  - **Slash command hints in workflow messages** — Workflow completion messages now display helpful slash command hints for next steps (#603)
+  - **Windsurf workflow file path** — Updated Windsurf adapter to use the correct `workflows` directory instead of the legacy `commands` path (#610)

+
+  The workflow has been rebuilt from the ground up. OPSX replaces the old phase-locked `/openspec:*` commands with an action-based system where AI understands what artifacts exist, what's ready to create, and what each action unlocks.
+
+  ### Breaking Changes
+
+  - **Old commands removed** — `/openspec:proposal`, `/openspec:apply`, and `/openspec:archive` no longer exist
+  - **Config files removed** — Tool-specific instruction files (`CLAUDE.md`, `.cursorrules`, `AGENTS.md`, `project.md`) are no longer generated
+  - **Migration** — Run `openspec init` to upgrade. Legacy artifacts are detected and cleaned up with confirmation.
+
+  ### From Static Prompts to Dynamic Instructions
+
+  **Before:** AI received the same static instructions every time, regardless of project state.
+
+  **Now:** Instructions are dynamically assembled from three layers:
+
+  1. **Context** — Project background from `config.yaml` (tech stack, conventions)
+  2. **Rules** — Artifact-specific constraints (e.g., "propose spike tasks for unknowns")
+  3. **Template** — The actual structure for the output file
+
+  AI queries the CLI for real-time state: which artifacts exist, what's ready to create, what dependencies are satisfied, and what each action unlocks.
+
+  ### From Phase-Locked to Action-Based
+
+  **Before:** Linear workflow — proposal → apply → archive. Couldn't easily go back or iterate.
+
+  **Now:** Flexible actions on a change. Edit any artifact anytime. The artifact graph tracks state automatically.
+
+  | Command              | What it does                                         |
+  | -------------------- | ---------------------------------------------------- |
+  | `/opsx:explore`      | Think through ideas before committing to a change    |
+  | `/opsx:new`          | Start a new change                                   |
+  | `/opsx:continue`     | Create one artifact at a time (step-through)         |
+  | `/opsx:ff`           | Create all planning artifacts at once (fast-forward) |
+  | `/opsx:apply`        | Implement tasks                                      |
+  | `/opsx:verify`       | Validate implementation matches artifacts            |
+  | `/opsx:sync`         | Sync delta specs to main specs                       |
+  | `/opsx:archive`      | Archive completed change                             |
+  | `/opsx:bulk-archive` | Archive multiple changes with conflict detection     |
+  | `/opsx:onboard`      | Guided 15-minute walkthrough of complete workflow    |
+
+  ### From Text Merging to Semantic Spec Syncing
+
+  **Before:** Spec updates required manual merging or wholesale file replacement.
+
+  **Now:** Delta specs use semantic markers that AI understands:
+
+  - `## ADDED Requirements` — New requirements to add
+  - `## MODIFIED Requirements` — Partial updates (add scenario without copying existing ones)
+  - `## REMOVED Requirements` — Delete with reason and migration notes
+  - `## RENAMED Requirements` — Rename preserving content
+
+  Archive parses these at the requirement level, not brittle header matching.
+
+  ### From Scattered Files to Agent Skills
+
+  **Before:** 8+ config files at project root + slash commands scattered across 21 tool-specific locations with different formats.
+
+  **Now:** Single `.claude/skills/` directory with YAML-fronted markdown files. Auto-detected by Claude Code, Cursor, Windsurf. Cross-editor compatible.
+
+  ### New Features
+
+  - **Onboarding skill** — `/opsx:onboard` walks new users through their first complete change with codebase-aware task suggestions and step-by-step narration (11 phases, ~15 minutes)
+
+  - **21 AI tools supported** — Claude Code, Cursor, Windsurf, Continue, Gemini CLI, GitHub Copilot, Amazon Q, Cline, RooCode, Kilo Code, Auggie, CodeBuddy, Qoder, Qwen, CoStrict, Crush, Factory, OpenCode, Antigravity, iFlow, and Codex
+
+  - **Interactive setup** — `openspec init` shows animated welcome screen and searchable multi-select for choosing tools. Pre-selects already-configured tools for easy refresh.
+
+  - **Customizable schemas** — Define custom artifact workflows in `openspec/schemas/` without touching package code. Teams can share workflows via version control.
+
+  ### Bug Fixes
+
+  - Fixed Claude Code YAML parsing failure when command names contained colons
+  - Fixed task file parsing to handle trailing whitespace on checkbox lines
+  - Fixed JSON instruction output to separate context/rules from template — AI was copying constraint blocks into artifact files
+
+  ### Documentation
+
+  - New getting-started guide, CLI reference, concepts documentation
+  - Removed misleading "edit mid-flight and continue" claims that weren't implemented
+  - Added migration guide for upgrading from pre-OPSX versions
+

+  - **Schema management commands** — New `openspec schema` commands (`list`, `show`, `export`, `validate`) for inspecting and managing artifact schemas (experimental)
+
+  **Bug Fixes**

+- [#516](https://github.com/Fission-AI/OpenSpec/pull/516) [`b5a8847`](https://github.com/Fission-AI/OpenSpec/commit/b5a884748be6156a7bb140b4941cfec4f20a9fc8) Thanks [@TabishB](https://github.com/TabishB)! - Add feedback command and Nix flake support
+
+  **New Features**
+
+  - **Feedback command** — Submit feedback directly from the CLI with `openspec feedback`, which creates GitHub Issues with automatic metadata inclusion and graceful fallback for manual submission
+  - **Nix flake support** — Install and develop openspec using Nix with the new `flake.nix`, including automated flake maintenance and CI validation
+
+  **Bug Fixes**
+
+  - **Explore mode guardrails** — Explore mode now explicitly prevents implementation, keeping the focus on thinking and discovery while still allowing artifact creation
+
+  **Other**
+
+  - Improved change inference in `opsx apply` — automatically detects the target change from conversation context or prompts when ambiguous
+  - Streamlined archive sync assessment with clearer delta spec location guidance

+
+  **New Features**
+
+  - **`/opsx:verify` command** — Validate that change implementations match their specifications
+
+  **Bug Fixes**
+
+  - Fixed vitest process storms by capping worker parallelism
+  - Fixed agent workflows to use non-interactive mode for validation commands
+  - Fixed PowerShell completions generator to remove trailing commas
+
+## 0.19.0
+
+### Minor Changes
+
+- eb152eb: Add Continue IDE support, shell completions, and `/opsx:explore` command
+
+  **New Features**
+
+  - **Continue IDE support** – OpenSpec now generates slash commands for [Continue](https://continue.dev/), expanding editor integration options alongside Cursor, Windsurf, Claude Code, and others
+  - **Shell completions for Bash, Fish, and PowerShell** – Run `openspec completion install` to set up tab completion in your preferred shell
+  - **`/opsx:explore` command** – A new thinking partner mode for exploring ideas and investigating problems before committing to changes
+  - **Codebuddy slash command improvements** – Updated frontmatter format for better compatibility
+
+  **Bug Fixes**
+
+  - Shell completions now correctly offer parent-level flags (like `--help`) when a command has subcommands
+  - Fixed Windows compatibility issues in tests
+
+  **Other**
+
+  - Added optional anonymous usage statistics to help understand how OpenSpec is used. This is **opt-out** by default – set `OPENSPEC_TELEMETRY=0` or `DO_NOT_TRACK=1` to disable. Only command names and version are collected; no arguments, file paths, or content. Automatically disabled in CI environments.
+
+## 0.18.0

-# OpenSpec
+### Teams
 
-OpenSpec aligns humans and AI coding assistants with spec-driven development so you agree on what to build before any code is written. **No API keys required.**
+Using OpenSpec in a team? [Email here](mailto:teams@openspec.dev) for access to our Slack channel.
 
-## Why OpenSpec?
+<!-- TODO: Add GIF demo of /opsx:new → /opsx:archive workflow -->
 
-AI coding assistants are powerful but unpredictable when requirements live in chat history. OpenSpec adds a lightweight specification workflow that locks intent before implementation, giving you deterministic, reviewable outputs.
+## See it in action
 
-Key outcomes:
-- Human and AI stakeholders agree on specs before work begins.
-- Structured change folders (proposals, tasks, and spec updates) keep scope explicit and auditable.
-- Shared visibility into what's proposed, active, or archived.
-- Works with the AI tools you already use: custom slash commands where supported, context rules everywhere else.
+```text
+You: /opsx:new add-dark-mode
+AI:  Created openspec/changes/add-dark-mode/
+     Ready to create: proposal
 
-## How OpenSpec compares (at a glance)
+You: /opsx:ff   # "fast-forward" - generate all planning docs
+AI:  ✓ proposal.md — why we're doing this, what's changing
+     ✓ specs/       — requirements and scenarios
+     ✓ design.md    — technical approach
+     ✓ tasks.md     — implementation checklist
+     Ready for implementation!
 
-- **Lightweight**: simple workflow, no API keys, minimal setup.
-- **Brownfield-first**: works great beyond 0→1. OpenSpec separates the source of truth from proposals: `openspec/specs/` (current truth) and `openspec/changes/` (proposed updates). This keeps diffs explicit and manageable across features.
-- **Change tracking**: proposals, tasks, and spec deltas live together; archiving merges the approved updates back into specs.
-- **Compared to spec-kit & Kiro**: those shine for brand-new features (0→1). OpenSpec also excels when modifying existing behavior (1→n), especially when updates span multiple specs.

-### Install & Initialize
-
-#### Prerequisites
-- **Node.js >= 20.19.0** - Check your version with `node --version`
-
-#### Step 1: Install the CLI globally
+Install OpenSpec globally:
 
 ```bash
 npm install -g @fission-ai/openspec@latest
 ```
 
-Verify installation:
-```bash
-openspec --version
-```
+Then navigate to your project directory and initialize:
 
-#### Step 2: Initialize OpenSpec in your project
-
-Navigate to your project directory:
-```bash
-cd my-project
-```
-
-Run the initialization:
 ```bash
+cd your-project
 openspec init
 ```
 
-**What happens during initialization:**
-- You'll be prompted to pick any natively supported AI tools (Claude Code, CodeBuddy, Cursor, OpenCode, Qoder,etc.); other assistants always rely on the shared `AGENTS.md` stub
-- OpenSpec automatically configures slash commands for the tools you choose and always writes a managed `AGENTS.md` hand-off at the project root
-- A new `openspec/` directory structure is created in your project
+Now tell your AI: `/opsx:new <what-you-want-to-build>`
 
-**After setup:**
-- Primary AI tools can trigger `/openspec` workflows without additional configuration
-- Run `openspec list` to verify the setup and view any active changes
-- If your coding assistant doesn't surface the new slash commands right away, restart it. Slash commands are loaded at startup,
-  so a fresh launch ensures they appear
+> [!NOTE]
+> Not sure if your tool is supported? [View the full list](docs/supported-tools.md) – we support 20+ tools and growing.
+>
+> Also works with pnpm, yarn, bun, and nix. [See installation options](docs/installation.md).
 
-### Optional: Populate Project Context
+## Docs
 
-After `openspec init` completes, you'll receive a suggested prompt to help populate your project context:
+→ **[Getting Started](docs/getting-started.md)**: first steps<br>
+→ **[Workflows](docs/workflows.md)**: combos and patterns<br>
+→ **[Commands](docs/commands.md)**: slash commands & skills<br>
+→ **[CLI](docs/cli.md)**: terminal reference<br>
+→ **[Supported Tools](docs/supported-tools.md)**: tool integrations & install paths<br>
+→ **[Concepts](docs/concepts.md)**: how it all fits<br>
+→ **[Multi-Language](docs/multi-language.md)**: multi-language support<br>
+→ **[Customization](docs/customization.md)**: make it yours
 
-```text
-Populate your project context:
-"Please read openspec/project.md and help me fill it out with details about my project, tech stack, and conventions"
-```
 
-Use `openspec/project.md` to define project-level conventions, standards, architectural patterns, and other guidelines that should be followed across all changes.
+## Why OpenSpec?
 
-### Create Your First Change
+AI coding assistants are powerful but unpredictable when requirements live only in chat history. OpenSpec adds a lightweight spec layer so you agree on what to build before any code is written.
 
-Here's a real example showing the complete OpenSpec workflow. This works with any AI tool. Those with native slash commands will recognize the shortcuts automatically.
+- **Agree before you build** — human and AI align on specs before code gets written
+- **Stay organized** — each change gets its own folder with proposal, specs, design, and tasks
+- **Work fluidly** — update any artifact anytime, no rigid phase gates
+- **Use your tools** — works with 20+ AI assistants via slash commands
 
-#### 1. Draft the Proposal
-Start by asking your AI to create a change proposal:
+### How we compare
 
-```text
-You: Create an OpenSpec change proposal for adding profile search filters by role and team
-     (Shortcut for tools with slash commands: /openspec:proposal Add profile search filters)
+**vs. [Spec Kit](https://github.com/github/spec-kit)** (GitHub) — Thorough but heavyweight. Rigid phase gates, lots of Markdown, Python setup. OpenSpec is lighter and lets you iterate freely.
 
-AI:  I'll create an OpenSpec change proposal for profile filters.
-     *Scaffolds openspec/changes/add-profile-filters/ with proposal.md, tasks.md, spec deltas.*
-```
+**vs. [Kiro](https://kiro.dev)** (AWS) — Powerful but you're locked into their IDE and limited to Claude models. OpenSpec works with the tools you already use.
 
-#### 2. Verify & Review
-Check that the change was created correctly and review the proposal:
-
-```bash
-$ openspec list                             # Confirm the change folder exists
-$ openspec validate add-profile-filters     # Validate spec formatting
-$ openspec show add-profile-filters         # Review proposal, tasks, and spec delta
-```
-
-#### 3. Refine the Specs
-Iterate on the specifications until they match your needs:
-
-```text
-You: Can you add acceptance criteria for the role and team filters?
-
-AI:  I'll update the spec delta with scenarios for role and team filters.
-     *Edits openspec/changes/add-profile-filters/specs/profile/spec.md and tasks.md.*
-```
-
-#### 4. Implement the Change
-Once specs look good, start implementation:
-
-```text
-You: The specs look good. Let's implement this change.
-     (Shortcut for tools with slash commands: /openspec:apply add-profile-filters)
-
-AI:  I'll work through the tasks in the add-profile-filters change.
-     *Implements tasks from openspec/changes/add-profile-filters/tasks.md*
-     *Marks tasks complete: Task 1.1 ✓, Task 1.2 ✓, Task 2.1 ✓...*
-```
-
-#### 5. Archive the Completed Change
-After implementation is complete, archive the change:
-
-```text
-AI:  All tasks are complete. The implementation is ready.
-
-You: Please archive the change
-     (Shortcut for tools with slash commands: /openspec:archive add-profile-filters)
-
-AI:  I'll archive the add-profile-filters change.
-    *Runs: openspec archive add-profile-filters --yes*
-     ✓ Change archived successfully. Specs updated. Ready for the next feature!
-```
-
-Or run the command yourself in terminal:
-```bash
-$ openspec archive add-profile-filters --yes  # Archive the completed change without prompts
-```
-
-**Note:** Tools with native slash commands (Claude Code, CodeBuddy, Cursor, Codex, Qoder, RooCode) can use the shortcuts shown. All other tools work with natural language requests to "create an OpenSpec proposal", "apply the OpenSpec change", or "archive the change".
-
-## Command Reference
-
-```bash
-openspec list               # View active change folders
-openspec view               # Interactive dashboard of specs and changes
-openspec show <change>      # Display change details (proposal, tasks, spec updates)
-openspec validate <change>  # Check spec formatting and structure
-openspec archive <change> [--yes|-y]   # Move a completed change into archive/ (non-interactive with --yes)
-```
-
-## Example: How AI Creates OpenSpec Files
-
-When you ask your AI assistant to "add two-factor authentication", it creates:
-
-```
-openspec/
-├── specs/
-│   └── auth/
-│       └── spec.md           # Current auth spec (if exists)
-└── changes/
-    └── add-2fa/              # AI creates this entire structure
-        ├── proposal.md       # Why and what changes
-        ├── tasks.md          # Implementation checklist
-        ├── design.md         # Technical decisions (optional)
-        └── specs/
-            └── auth/
-                └── spec.md   # Delta showing additions
-```
-
-### AI-Generated Spec (created in `openspec/specs/auth/spec.md`):
-
-```markdown
-# Auth Specification
-
-## Purpose
-Authentication and session management.
-
-## Requirements
-### Requirement: User Authentication
-The system SHALL issue a JWT on successful login.
-
-#### Scenario: Valid credentials
-- WHEN a user submits valid credentials
-- THEN a JWT is returned
-```
-
-### AI-Generated Change Delta (created in `openspec/changes/add-2fa/specs/auth/spec.md`):
-
-```markdown
-# Delta for Auth
-
-## ADDED Requirements
-### Requirement: Two-Factor Authentication
-The system MUST require a second factor during login.
-
-#### Scenario: OTP required
-- WHEN a user submits valid credentials
-- THEN an OTP challenge is required
-```
-
-### AI-Generated Tasks (created in `openspec/changes/add-2fa/tasks.md`):
-
-```markdown
-## 1. Database Setup
-- [ ] 1.1 Add OTP secret column to users table

-**Important:** You don't create these files manually. Your AI assistant generates them based on your requirements and the existing codebase.
-
-## Understanding OpenSpec Files
-
-### Delta Format
-
-Deltas are "patches" that show how specs change:
-
-- **`## ADDED Requirements`** - New capabilities
-- **`## MODIFIED Requirements`** - Changed behavior (include complete updated text)
-- **`## REMOVED Requirements`** - Deprecated features
-
-**Format requirements:**
-- Use `### Requirement: <name>` for headers
-- Every requirement needs at least one `#### Scenario:` block
-- Use SHALL/MUST in requirement text
-
-## How OpenSpec Compares
-
-### vs. spec-kit
-OpenSpec’s two-folder model (`openspec/specs/` for the current truth, `openspec/changes/` for proposed updates) keeps state and diffs separate. This scales when you modify existing features or touch multiple specs. spec-kit is strong for greenfield/0→1 but provides less structure for cross-spec updates and evolving features.
-
-### vs. Kiro.dev
-OpenSpec groups every change for a feature in one folder (`openspec/changes/feature-name/`), making it easy to track related specs, tasks, and designs together. Kiro spreads updates across multiple spec folders, which can make feature tracking harder.
-
-### vs. No Specs
-Without specs, AI coding assistants generate code from vague prompts, often missing requirements or adding unwanted features. OpenSpec brings predictability by agreeing on the desired behavior before any code is written.
-
-## Team Adoption
-
-1. **Initialize OpenSpec** – Run `openspec init` in your repo.
-2. **Start with new features** – Ask your AI to capture upcoming work as change proposals.
-3. **Grow incrementally** – Each change archives into living specs that document your system.
-4. **Stay flexible** – Different teammates can use Claude Code, CodeBuddy, Cursor, or any AGENTS.md-compatible tool while sharing the same specs.
-
-Run `openspec update` whenever someone switches tools so your agents pick up the latest instructions and slash-command bindings.
+**vs. nothing** — AI coding without specs means vague prompts and unpredictable results. OpenSpec brings predictability without the ceremony.
 
 ## Updating OpenSpec
 
-1. **Upgrade the package**
-   ```bash
-   npm install -g @fission-ai/openspec@latest
-   ```
-2. **Refresh agent instructions**
-   - Run `openspec update` inside each project to regenerate AI guidance and ensure the latest slash commands are active.
+**Upgrade the package**
+
+```bash
+npm install -g @fission-ai/openspec@latest
+```
+
+**Refresh agent instructions**
+
+Run this inside each project to regenerate AI guidance and ensure the latest slash commands are active:
+
+```bash
+openspec update
+```
+
+## Usage Notes
+
+**Model selection**: OpenSpec works best with high-reasoning models. We recommend Opus 4.5 and GPT 5.2 for both planning and implementation.
+
+**Context hygiene**: OpenSpec benefits from a clean context window. Clear your context before starting implementation and maintain good context hygiene throughout your session.
 
 ## Contributing
 
+**Small fixes** — Bug fixes, typo corrections, and minor improvements can be submitted directly as PRs.
+
+**Larger changes** — For new features, significant refactors, or architectural changes, please submit an OpenSpec change proposal first so we can align on intent and goals before implementation begins.
+
+When writing proposals, keep the OpenSpec philosophy in mind: we serve a wide variety of users across different coding agents, models, and use cases. Changes should work well for everyone.
+
+**AI-generated code is welcome** — as long as it's been tested and verified. PRs containing AI-generated code should mention the coding agent and model used (e.g., "Generated with Claude Code using claude-opus-4-5-20251101").
+
+### Development

+
+# OpenSpec
+
+OpenSpec aligns humans and AI coding assistants with spec-driven development so you agree on what to build before any code is written. **No API keys required.**
+
+## Why OpenSpec?
+
+AI coding assistants are powerful but unpredictable when requirements live in chat history. OpenSpec adds a lightweight specification workflow that locks intent before implementation, giving you deterministic, reviewable outputs.
+
+Key outcomes:
+- Human and AI stakeholders agree on specs before work begins.
+- Structured change folders (proposals, tasks, and spec updates) keep scope explicit and auditable.
+- Shared visibility into what's proposed, active, or archived.
+- Works with the AI tools you already use: custom slash commands where supported, context rules everywhere else.
+
+## How OpenSpec compares (at a glance)
+
+- **Lightweight**: simple workflow, no API keys, minimal setup.
+- **Brownfield-first**: works great beyond 0→1. OpenSpec separates the source of truth from proposals: `openspec/specs/` (current truth) and `openspec/changes/` (proposed updates). This keeps diffs explicit and manageable across features.
+- **Change tracking**: proposals, tasks, and spec deltas live together; archiving merges the approved updates back into specs.
+- **Compared to spec-kit & Kiro**: those shine for brand-new features (0→1). OpenSpec also excels when modifying existing behavior (1→n), especially when updates span multiple specs.
+
+See the full comparison in [How OpenSpec Compares](#how-openspec-compares).

+
+### Install & Initialize
+
+#### Prerequisites
+- **Node.js >= 20.19.0** - Check your version with `node --version`
+
+#### Step 1: Install the CLI globally
+
+**Option A: Using npm**
+
+```bash
+npm install -g @fission-ai/openspec@latest
+```
+
+Verify installation:
+```bash
+openspec --version
+```
+
+**Option B: Using Nix (NixOS and Nix package manager)**
+
+Run OpenSpec directly without installation:
+```bash
+nix run github:Fission-AI/OpenSpec -- init
+```
+
+Or install to your profile:
+```bash
+nix profile install github:Fission-AI/OpenSpec
+```
+
+Or add to your development environment in `flake.nix`:
+```nix
+{
+  inputs = {
+    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
+    openspec.url = "github:Fission-AI/OpenSpec";
+  };
+
+  outputs = { nixpkgs, openspec, ... }: {
+    devShells.x86_64-linux.default = nixpkgs.legacyPackages.x86_64-linux.mkShell {
+      buildInputs = [ openspec.packages.x86_64-linux.default ];
+    };
+  };
+}
+```
+
+Verify installation:
+```bash
+openspec --version
+```
+
+#### Step 2: Initialize OpenSpec in your project
+
+Navigate to your project directory:
+```bash
+cd my-project
+```
+
+Run the initialization:
+```bash
+openspec init
+```
+
+**What happens during initialization:**
+- You'll be prompted to pick any natively supported AI tools (Claude Code, CodeBuddy, Cursor, OpenCode, Qoder,etc.); other assistants always rely on the shared `AGENTS.md` stub
+- OpenSpec automatically configures slash commands for the tools you choose and always writes a managed `AGENTS.md` hand-off at the project root
+- A new `openspec/` directory structure is created in your project
+
+**After setup:**
+- Primary AI tools can trigger `/openspec` workflows without additional configuration
+- Run `openspec list` to verify the setup and view any active changes
+- If your coding assistant doesn't surface the new slash commands right away, restart it. Slash commands are loaded at startup,
+  so a fresh launch ensures they appear
+
+### Optional: Populate Project Context
+
+After `openspec init` completes, you'll receive a suggested prompt to help populate your project context:
+
+```text
+Populate your project context:
+"Please read openspec/project.md and help me fill it out with details about my project, tech stack, and conventions"
+```
+
+Use `openspec/project.md` to define project-level conventions, standards, architectural patterns, and other guidelines that should be followed across all changes.
+
+### Create Your First Change
+
+Here's a real example showing the complete OpenSpec workflow. This works with any AI tool. Those with native slash commands will recognize the shortcuts automatically.
+
+#### 1. Draft the Proposal
+Start by asking your AI to create a change proposal:
+
+```text
+You: Create an OpenSpec change proposal for adding profile search filters by role and team
+     (Shortcut for tools with slash commands: /openspec:proposal Add profile search filters)
+
+AI:  I'll create an OpenSpec change proposal for profile filters.
+     *Scaffolds openspec/changes/add-profile-filters/ with proposal.md, tasks.md, spec deltas.*
+```
+
+#### 2. Verify & Review
+Check that the change was created correctly and review the proposal:
+
+```bash
+$ openspec list                             # Confirm the change folder exists
+$ openspec validate add-profile-filters     # Validate spec formatting
+$ openspec show add-profile-filters         # Review proposal, tasks, and spec delta
+```
+
+#### 3. Refine the Specs
+Iterate on the specifications until they match your needs:
+
+```text
+You: Can you add acceptance criteria for the role and team filters?
+
+AI:  I'll update the spec delta with scenarios for role and team filters.
+     *Edits openspec/changes/add-profile-filters/specs/profile/spec.md and tasks.md.*
+```
+
+#### 4. Implement the Change
+Once specs look good, start implementation:
+
+```text
+You: The specs look good. Let's implement this change.
+     (Shortcut for tools with slash commands: /openspec:apply add-profile-filters)
+
+AI:  I'll work through the tasks in the add-profile-filters change.
+     *Implements tasks from openspec/changes/add-profile-filters/tasks.md*
+     *Marks tasks complete: Task 1.1 ✓, Task 1.2 ✓, Task 2.1 ✓...*
+```
+
+#### 5. Archive the Completed Change
+After implementation is complete, archive the change:
+
+```text
+AI:  All tasks are complete. The implementation is ready.
+
+You: Please archive the change
+     (Shortcut for tools with slash commands: /openspec:archive add-profile-filters)
+
+AI:  I'll archive the add-profile-filters change.
+    *Runs: openspec archive add-profile-filters --yes*
+     ✓ Change archived successfully. Specs updated. Ready for the next feature!
+```
+
+Or run the command yourself in terminal:
+```bash
+$ openspec archive add-profile-filters --yes  # Archive the completed change without prompts
+```
+
+**Note:** Tools with native slash commands (Claude Code, CodeBuddy, Cursor, Codex, Qoder, RooCode) can use the shortcuts shown. All other tools work with natural language requests to "create an OpenSpec proposal", "apply the OpenSpec change", or "archive the change".
+
+## Command Reference
+
+```bash
+openspec list               # View active change folders
+openspec view               # Interactive dashboard of specs and changes
+openspec show <change>      # Display change details (proposal, tasks, spec updates)
+openspec validate <change>  # Check spec formatting and structure
+openspec archive <change> [--yes|-y]   # Move a completed change into archive/ (non-interactive with --yes)
+```
+
+## Example: How AI Creates OpenSpec Files
+
+When you ask your AI assistant to "add two-factor authentication", it creates:
+
+```
+openspec/
+├── specs/
+│   └── auth/
+│       └── spec.md           # Current auth spec (if exists)
+└── changes/
+    └── add-2fa/              # AI creates this entire structure
+        ├── proposal.md       # Why and what changes
+        ├── tasks.md          # Implementation checklist
+        ├── design.md         # Technical decisions (optional)
+        └── specs/
+            └── auth/
+                └── spec.md   # Delta showing additions
+```
+
+### AI-Generated Spec (created in `openspec/specs/auth/spec.md`):
+
+```markdown
+# Auth Specification
+
+## Purpose
+Authentication and session management.
+
+## Requirements
+### Requirement: User Authentication
+The system SHALL issue a JWT on successful login.
+
+#### Scenario: Valid credentials
+- WHEN a user submits valid credentials
+- THEN a JWT is returned
+```
+
+### AI-Generated Change Delta (created in `openspec/changes/add-2fa/specs/auth/spec.md`):
+
+```markdown
+# Delta for Auth
+
+## ADDED Requirements
+### Requirement: Two-Factor Authentication
+The system MUST require a second factor during login.
+
+#### Scenario: OTP required
+- WHEN a user submits valid credentials
+- THEN an OTP challenge is required
+```
+
+### AI-Generated Tasks (created in `openspec/changes/add-2fa/tasks.md`):
+
+```markdown
+## 1. Database Setup
+- [ ] 1.1 Add OTP secret column to users table
+- [ ] 1.2 Create OTP verification logs table
+

+- [ ] 2.3 Add OTP verification endpoint
+
+## 3. Frontend Updates

+```
+
+**Important:** You don't create these files manually. Your AI assistant generates them based on your requirements and the existing codebase.

+<summary><strong>🧪 OPSX: Fluid, Iterative Workflow</strong> (Claude Code only)</summary>
+
+**Why this exists:**
+- Standard workflow is locked down — you can't tweak instructions or customize
+- When AI output is bad, you can't improve the prompts yourself
+- Same workflow for everyone, no way to match how your team works
+
+**What's different:**
+- **Hackable** — edit templates and schemas yourself, test immediately, no rebuild
+- **Granular** — each artifact has its own instructions, test and tweak individually
+- **Customizable** — define your own workflows, artifacts, and dependencies
+- **Fluid** — no phase gates, update any artifact anytime
+
+```
+You can always go back:

+```
+
+**Subcommands:**
+
+| Subcommand | Description |
+|------------|-------------|
+| `path` | Show config file location |
+| `list` | Show all current settings |
+| `get <key>` | Get a specific value |
+| `set <key> <value>` | Set a value |
+| `unset <key>` | Remove a key |
+| `reset` | Reset to defaults |
+| `edit` | Open in `$EDITOR` |
+| `profile [preset]` | Configure workflow profile interactively or via preset |
+
+**Examples:**
+
+```bash
+# Show config file path
+openspec config path
+
+# List all settings
+openspec config list
+
+# Get a specific value
+openspec config get telemetry.enabled
+
+# Set a value
+openspec config set telemetry.enabled false
+
+# Set a string value explicitly
+openspec config set user.name "My Name" --string
+
+# Remove a custom setting
+openspec config unset user.name
+
+# Reset all configuration
+openspec config reset --all --yes
+
+# Edit config in your editor
+openspec config edit
+
+# Configure profile with action-based wizard
+openspec config profile
+
+# Fast preset: switch workflows to core (keeps delivery mode)
+openspec config profile core
+```
+
+`openspec config profile` starts with a current-state summary, then lets you choose:
+- Change delivery + workflows
+- Change delivery only
+- Change workflows only
+- Keep current settings (exit)
+
+If you keep current settings, no changes are written and no update prompt is shown.
+If there are no config changes but the current project files are out of sync with your global profile/delivery, OpenSpec will show a warning and suggest running `openspec update`.
+Pressing `Ctrl+C` also cancels the flow cleanly (no stack trace) and exits with code `130`.
+In the workflow checklist, `[x]` means the workflow is selected in global config. To apply those selections to project files, run `openspec update` (or choose `Apply changes to this project now?` when prompted inside a project).
+
+**Interactive examples:**
+
+```bash
+# Delivery-only update
+openspec config profile
+# choose: Change delivery only
+# choose delivery: Skills only
+
+# Workflows-only update
+openspec config profile
+# choose: Change workflows only
+# toggle workflows in the checklist, then confirm
+```

+- Can transition to `/opsx:new` when insights crystallize
+
+**Example:**
+```text
+You: /opsx:explore
+
+AI:  What would you like to explore?
+
+You: How should we handle authentication for the mobile app?
+
+AI:  Let me investigate your current auth setup...
+     [Analyzes codebase]
+
+     I see you're using session-based auth for the web app.
+     For mobile, we have three main options:
+
+     1. JWT tokens (stateless, works offline)
+     2. OAuth2 (if you need third-party login)
+     3. Extend current sessions (simpler, but requires connectivity)
+
+     Your API already has CORS configured. Which direction interests you?
+
+You: Let's go with JWT. Can we start a change for that?
+
+AI:  Ready when you are. Run /opsx:new add-jwt-auth to begin.
+```
+
+**Tips:**
+- Use when requirements are unclear or you need to investigate
+- No artifacts are created during exploration
+- Good for comparing multiple approaches before deciding
+- Can read files and search the codebase
+
+---
+
+### `/opsx:new`
+
+Start a new change. Creates the change folder structure and scaffolds it with the selected schema.
+
+**Syntax:**
+```
+/opsx:new [change-name] [--schema <schema-name>]
+```
+
+**Arguments:**
+| Argument | Required | Description |
+|----------|----------|-------------|
+| `change-name` | No | Name for the change folder (prompted if not provided) |
+| `--schema` | No | Workflow schema to use (default: from config or `spec-driven`) |
+
+**What it does:**
+- Creates `openspec/changes/<change-name>/` directory
+- Creates `.openspec.yaml` metadata file in the change folder
+- Shows the first artifact template ready for creation
+- Prompts for change name and schema if not provided
+
+**What it creates:**
+```
+openspec/changes/<change-name>/
+└── .openspec.yaml    # Change metadata (schema, created date)
+```
+
+**Example:**
+```
+You: /opsx:new add-dark-mode
+
+AI:  Created openspec/changes/add-dark-mode/
+     Schema: spec-driven
+
+     Ready to create: proposal
+     Use /opsx:continue to create it, or /opsx:ff to create all artifacts.
+```
+
+**Tips:**
+- Use descriptive names: `add-feature`, `fix-bug`, `refactor-module`
+- Avoid generic names like `update`, `changes`, `wip`
+- Schema can also be set in project config (`openspec/config.yaml`)
+
+---
+
+### `/opsx:continue`
+
+Create the next artifact in the dependency chain. Creates one artifact at a time for incremental progress.
+
+**Syntax:**
+```
+/opsx:continue [change-name]
+```
+
+**Arguments:**
+| Argument | Required | Description |
+|----------|----------|-------------|
+| `change-name` | No | Which change to continue (inferred from context if not provided) |
+
+**What it does:**
+- Queries the artifact dependency graph
+- Shows which artifacts are ready vs blocked
+- Creates the first ready artifact
+- Reads dependency files for context
+- Shows what becomes available after creation
+
+**Example:**
+```
+You: /opsx:continue
+
+AI:  Change: add-dark-mode
+
+     Artifact status:
+     ✓ proposal    (done)
+     ◆ specs       (ready)
+     ◆ design      (ready)
+     ○ tasks       (blocked - needs: specs)
+
+     Creating specs...
+
+     [Reads proposal.md, creates specs based on requirements]
+
+     ✓ Created openspec/changes/add-dark-mode/specs/ui/spec.md
+
+     Now available: tasks
+     Run /opsx:continue to create the next artifact.
+```
+
+**Tips:**
+- Use when you want to review each artifact before proceeding
+- Good for complex changes where you want control
+- Multiple artifacts may become ready simultaneously
+- You can edit created artifacts before continuing
+
+---
+
+### `/opsx:ff`
+
+Fast-forward through artifact creation. Creates all planning artifacts at once.
+
+**Syntax:**
+```
+/opsx:ff [change-name]
+```
+
+**Arguments:**
+| Argument | Required | Description |
+|----------|----------|-------------|
+| `change-name` | No | Which change to fast-forward (inferred from context if not provided) |
+
+**What it does:**
+- Creates all artifacts in dependency order
+- Tracks progress via todo list
+- Stops when all `apply-required` artifacts are complete
+- Reads each dependency before creating the next artifact
+
+**Example:**
+```
+You: /opsx:ff add-dark-mode
+
+AI:  Fast-forwarding add-dark-mode...
+
+     ✓ Creating proposal.md
+     ✓ Creating specs/ui/spec.md
+     ✓ Creating design.md
+     ✓ Creating tasks.md
+
+     All planning artifacts complete!
+     Ready for implementation. Run /opsx:apply to begin.
+```
+
+**Tips:**
+- Use when you have a clear picture of what you're building
+- Faster than `/opsx:continue` for straightforward changes
+- You can still edit artifacts afterward
+- Good for small to medium features
+
+---
+
+### `/opsx:apply`
+
+Implement tasks from the change. Works through the task list, writing code and checking off items.
+
+**Syntax:**
+```
+/opsx:apply [change-name]
+```
+
+**Arguments:**
+| Argument | Required | Description |
+|----------|----------|-------------|
+| `change-name` | No | Which change to implement (inferred from context if not provided) |
+
+**What it does:**
+- Reads `tasks.md` and identifies incomplete tasks
+- Works through tasks one by one
+- Writes code, creates files, runs tests as needed
+- Marks tasks complete with checkboxes `[x]`
+
+**Example:**
+```
+You: /opsx:apply
+
+AI:  Implementing add-dark-mode...
+
+     Reading tasks.md:
+     - [ ] 1.1 Create ThemeContext
+     - [ ] 1.2 Add CSS custom properties
+     - [ ] 1.3 Implement localStorage persistence
+
+     Working on 1.1: Create ThemeContext...
+     [Creates src/context/ThemeContext.tsx]
+
+     ✓ 1.1 Complete
+
+     Working on 1.2: Add CSS custom properties...
+     [Updates src/styles/globals.css]
+
+     ✓ 1.2 Complete
+     ...
+```
+
+**Tips:**
+- Can resume where you left off if interrupted
+- Use for parallel changes by specifying the change name
+- Completion state is tracked in `tasks.md` checkboxes
+
+---
+
+### `/opsx:verify`
+
+Validate that implementation matches your change artifacts. Checks completeness, correctness, and coherence.
+
+**Syntax:**
+```
+/opsx:verify [change-name]
+```
+
+**Arguments:**
+| Argument | Required | Description |
+|----------|----------|-------------|
+| `change-name` | No | Which change to verify (inferred from context if not provided) |
+
+**What it does:**
+- Checks three dimensions of implementation quality
+- Searches codebase for implementation evidence
+- Reports issues categorized as CRITICAL, WARNING, or SUGGESTION
+- Does not block archive, but surfaces issues
+
+**Verification dimensions:**
+
+| Dimension | What it validates |
+|-----------|-------------------|
+| **Completeness** | All tasks done, all requirements implemented, scenarios covered |
+| **Correctness** | Implementation matches spec intent, edge cases handled |
+| **Coherence** | Design decisions reflected in code, patterns consistent |
+
+**Example:**
+```
+You: /opsx:verify
+
+AI:  Verifying add-dark-mode...
+
+     COMPLETENESS
+     ✓ All 8 tasks in tasks.md are checked
+     ✓ All requirements in specs have corresponding code
+     ⚠ Scenario "System preference detection" has no test coverage
+
+     CORRECTNESS
+     ✓ Implementation matches spec intent
+     ✓ Edge cases from scenarios are handled
+     ✓ Error states match spec definitions
+
+     COHERENCE
+     ✓ Design decisions reflected in code structure
+     ✓ Naming conventions consistent with design.md
+     ⚠ Design mentions "CSS variables" but implementation uses Tailwind classes
+
+     SUMMARY
+     ─────────────────────────────
+     Critical issues: 0
+     Warnings: 2
+     Ready to archive: Yes (with warnings)
+
+     Recommendations:
+     1. Add test for system preference detection
+     2. Update design.md to reflect Tailwind usage, or refactor to use CSS variables
+```
+
+**Tips:**
+- Run before archiving to catch mismatches early
+- Warnings don't block archive but indicate potential issues
+- Good for reviewing AI's work before committing
+- Can reveal drift between artifacts and implementation
+
+---
+
+### `/opsx:sync`
+
+**Optional command.** Merge delta specs from a change into main specs. Archive will prompt to sync if needed, so you typically don't need to run this manually.
+
+**Syntax:**
+```
+/opsx:sync [change-name]
+```
+
+**Arguments:**
+| Argument | Required | Description |
+|----------|----------|-------------|
+| `change-name` | No | Which change to sync (inferred from context if not provided) |
+
+**What it does:**
+- Reads delta specs from change folder
+- Parses ADDED/MODIFIED/REMOVED/RENAMED sections
+- Merges changes into main `openspec/specs/` directory
+- Preserves existing content not mentioned in delta
+- Does not archive the change (remains active)
+
+**Example:**
+```text
+You: /opsx:sync
+
+AI:  Syncing add-dark-mode delta specs...
+
+     Reading: openspec/changes/add-dark-mode/specs/ui/spec.md
+     Target:  openspec/specs/ui/spec.md
+
+     Changes to apply:
+     ✓ ADDED: Theme Selection requirement (2 scenarios)
+     ✓ ADDED: Accessibility requirement (1 scenario)
+
+     Merging...
+     ✓ openspec/specs/ui/spec.md updated
+
+     Change remains active. Run /opsx:archive when ready to complete.
+```
+
+**When to use manually:**
+
+| Scenario | Use sync? |
+|----------|-----------|
+| Long-running change, want specs in main before archiving | Yes |
+| Multiple parallel changes need the updated base specs | Yes |
+| Want to preview/review the merge separately | Yes |
+| Quick change, going straight to archive | No (archive handles it) |
+
+**Tips:**
+- Sync is intelligent, not copy-paste
+- Can add scenarios to existing requirements without duplicating
+- Change stays active after sync (not archived)
+- Most users will never need to call this directly—archive prompts if needed
+
+---
+
+### `/opsx:archive`
+
+Archive a completed change. Finalizes the change and moves it to the archive folder.
+
+**Syntax:**
+```
+/opsx:archive [change-name]
+```
+
+**Arguments:**
+| Argument | Required | Description |
+|----------|----------|-------------|
+| `change-name` | No | Which change to archive (inferred from context if not provided) |
+
+**What it does:**
+- Checks artifact completion status
+- Checks task completion (warns if incomplete)
+- Offers to sync delta specs if not already synced
+- Moves change folder to `openspec/changes/archive/YYYY-MM-DD-<name>/`
+- Preserves all artifacts for audit trail
+
+**Example:**
+```text
+You: /opsx:archive
+
+AI:  Archiving add-dark-mode...
+
+     Artifact status:
+     ✓ proposal.md exists
+     ✓ specs/ exists
+     ✓ design.md exists
+     ✓ tasks.md exists (8/8 tasks complete)
+
+     Delta specs: Not yet synced
+     → Sync now? (recommended)
+
+You: Yes
+
+AI:  ✓ Synced specs to openspec/specs/ui/spec.md
+     ✓ Moved to openspec/changes/archive/2025-01-24-add-dark-mode/
+
+     Change archived successfully.
+```
+
+**Tips:**
+- Archive won't block on incomplete tasks, but will warn
+- Delta specs can be synced during archive or beforehand
+- Archived changes are preserved for history
+- Use `/opsx:verify` first to catch issues
+
+---
+
+### `/opsx:bulk-archive`
+
+Archive multiple completed changes at once. Handles spec conflicts between changes.
+
+**Syntax:**
+```
+/opsx:bulk-archive [change-names...]
+```
+
+**Arguments:**
+| Argument | Required | Description |
+|----------|----------|-------------|
+| `change-names` | No | Specific changes to archive (prompts to select if not provided) |
+
+**What it does:**
+- Lists all completed changes
+- Validates each change before archiving
+- Detects spec conflicts across changes
+- Resolves conflicts by checking what's actually implemented
+- Archives in chronological order
+
+**Example:**
+```
+You: /opsx:bulk-archive
+
+AI:  Found 3 completed changes:
+     - add-dark-mode (8/8 tasks complete)
+     - fix-login-bug (3/3 tasks complete)
+     - update-footer (2/2 tasks complete)
+
+     Checking for spec conflicts...
+     ⚠ add-dark-mode and update-footer both touch specs/ui/
+
+     Inspecting codebase to resolve...
+     Both changes are implemented. Will merge in chronological order:
+     1. add-dark-mode (created Jan 20)
+     2. update-footer (created Jan 22)
+
+     Archive all 3 changes?
+
+You: Yes
+
+AI:  ✓ Archived add-dark-mode
+     ✓ Archived fix-login-bug
+     ✓ Archived update-footer
+     Specs merged: add-dark-mode → update-footer
+```
+
+**Tips:**
+- Good for parallel work streams
+- Conflict resolution is agentic (checks codebase)
+- Changes are archived in order of creation
+- Prompts before overwriting spec content
+
+---
+
+### `/opsx:onboard`
+
+Guided onboarding through the complete OpenSpec workflow. An interactive tutorial using your actual codebase.
+
+**Syntax:**
+```
+/opsx:onboard
+```
+
+**What it does:**
+- Walks through a complete workflow cycle with narration
+- Scans your codebase for real improvement opportunities
+- Creates an actual change with real artifacts
+- Implements actual work (small, safe changes)
+- Archives the completed change
+- Explains each step as it happens
+
+**Phases:**
+1. Welcome and codebase analysis
+2. Finding an improvement opportunity
+3. Creating a change (`/opsx:new`)
+4. Writing the proposal
+5. Creating specs
+6. Writing the design
+7. Creating tasks
+8. Implementing tasks (`/opsx:apply`)
+9. Verifying implementation
+10. Archiving the change
+11. Summary and next steps
+
+**Example:**
+```
+You: /opsx:onboard
+
+AI:  Welcome to OpenSpec!
+
+     I'll walk you through the complete workflow using your actual codebase.
+     We'll find something small to improve, create a proper change for it,
+     implement it, and archive it.
+
+     Let me scan your codebase for opportunities...
+
+     [Analyzes codebase]
+
+     I found a few things we could work on:
+     1. Add input validation to the contact form
+     2. Improve error messages in the auth flow
+     3. Add loading states to async buttons
+
+     Which interests you? (or suggest something else)
+```
+
+**Tips:**
+- Best for new users learning the workflow
+- Uses real code, not toy examples
+- Creates a real change you can keep or discard
+- Takes 15-30 minutes to complete
+
+---
+
+## Command Syntax by AI Tool
+
+Different AI tools use slightly different command syntax. Use the format that matches your tool:
+
+| Tool | Syntax Example |
+|------|----------------|
+| Claude Code | `/opsx:new`, `/opsx:apply` |
+| Cursor | `/opsx-new`, `/opsx-apply` |
+| Windsurf | `/opsx-new`, `/opsx-apply` |
+| Copilot (IDE) | `/opsx-new`, `/opsx-apply` |
+| Trae | `/openspec-new-change`, `/openspec-apply-change` |
+
+The functionality is identical regardless of syntax.
+
+> **Note:** GitHub Copilot commands (`.github/prompts/*.prompt.md`) are only available in IDE extensions (VS Code, JetBrains, Visual Studio). GitHub Copilot CLI does not currently support custom prompt files — see [Supported Tools](supported-tools.md) for details and workarounds.
+
+---
+
+## Legacy Commands
+
+These commands use the older "all-at-once" workflow. They still work but OPSX commands are recommended.
+
+| Command | What it does |
+|---------|--------------|
+| `/openspec:proposal` | Create all artifacts at once (proposal, specs, design, tasks) |
+| `/openspec:apply` | Implement the change |
+| `/openspec:archive` | Archive the change |
+
+**When to use legacy commands:**
+- Existing projects using the old workflow
+- Simple changes where you don't need incremental artifact creation
+- Preference for the all-or-nothing approach
+
+**Migrating to OPSX:**
+Legacy changes can be continued with OPSX commands. The artifact structure is compatible.
+
+---
+
+## Troubleshooting
+
+### "Change not found"
+
+The command couldn't identify which change to work on.
+
+**Solutions:**
+- Specify the change name explicitly: `/opsx:apply add-dark-mode`
+- Check that the change folder exists: `openspec list`
+- Verify you're in the right project directory
+
+### "No artifacts ready"
+
+All artifacts are either complete or blocked by missing dependencies.
+
+**Solutions:**
+- Run `openspec status --change <name>` to see what's blocking
+- Check if required artifacts exist
+- Create missing dependency artifacts first
+
+### "Schema not found"
+
+The specified schema doesn't exist.
+
+**Solutions:**
+- List available schemas: `openspec schemas`
+- Check spelling of schema name
+- Create the schema if it's custom: `openspec schema init <name>`
+
+### Commands not recognized
+
+The AI tool doesn't recognize OpenSpec commands.
+
+**Solutions:**
+- Ensure OpenSpec is initialized: `openspec init`
+- Regenerate skills: `openspec update`
+- Check that `.claude/skills/` directory exists (for Claude Code)
+- Restart your AI tool to pick up new skills
+
+### Artifacts not generating properly
+
+The AI creates incomplete or incorrect artifacts.
+
+**Solutions:**
+- Add project context in `openspec/config.yaml`
+- Add per-artifact rules for specific guidance
+- Provide more detail in your change description
+- Use `/opsx:continue` instead of `/opsx:ff` for more control
+
+---
+
+## Next Steps

+- [Workflows](workflows.md) - Common patterns and when to use each command
+- [CLI](cli.md) - Terminal commands for management and validation
+- [Customization](customization.md) - Create custom schemas and workflows

+# Concepts
+
+This guide explains the core ideas behind OpenSpec and how they fit together. For practical usage, see [Getting Started](getting-started.md) and [Workflows](workflows.md).
+
+## Philosophy
+
+OpenSpec is built around four principles:
+
+```
+fluid not rigid       — no phase gates, work on what makes sense
+iterative not waterfall — learn as you build, refine as you go
+easy not complex      — lightweight setup, minimal ceremony
+brownfield-first      — works with existing codebases, not just greenfield
+```
+
+### Why These Principles Matter
+
+**Fluid not rigid.** Traditional spec systems lock you into phases: first you plan, then you implement, then you're done. OpenSpec is more flexible — you can create artifacts in any order that makes sense for your work.
+
+**Iterative not waterfall.** Requirements change. Understanding deepens. What seemed like a good approach at the start might not hold up after you see the codebase. OpenSpec embraces this reality.
+
+**Easy not complex.** Some spec frameworks require extensive setup, rigid formats, or heavyweight processes. OpenSpec stays out of your way. Initialize in seconds, start working immediately, customize only if you need to.
+
+**Brownfield-first.** Most software work isn't building from scratch — it's modifying existing systems. OpenSpec's delta-based approach makes it easy to specify changes to existing behavior, not just describe new systems.
+
+## The Big Picture
+
+OpenSpec organizes your work into two main areas:
+
+```
+┌─────────────────────────────────────────────────────────────────┐
+│                        openspec/                                 │
+│                                                                  │
+│   ┌─────────────────────┐      ┌──────────────────────────────┐ │
+│   │       specs/        │      │         changes/              │ │
+│   │                     │      │                               │ │
+│   │  Source of truth    │◄─────│  Proposed modifications       │ │
+│   │  How your system    │ merge│  Each change = one folder     │ │
+│   │  currently works    │      │  Contains artifacts + deltas  │ │
+│   │                     │      │                               │ │
+│   └─────────────────────┘      └──────────────────────────────┘ │
+│                                                                  │
+└─────────────────────────────────────────────────────────────────┘
+```
+
+**Specs** are the source of truth — they describe how your system currently behaves.
+
+**Changes** are proposed modifications — they live in separate folders until you're ready to merge them.
+
+This separation is key. You can work on multiple changes in parallel without conflicts. You can review a change before it affects the main specs. And when you archive a change, its deltas merge cleanly into the source of truth.
+
+## Specs
+
+Specs describe your system's behavior using structured requirements and scenarios.
+
+### Structure
+
+```
+openspec/specs/
+├── auth/
+│   └── spec.md           # Authentication behavior
+├── payments/
+│   └── spec.md           # Payment processing
+├── notifications/
+│   └── spec.md           # Notification system
+└── ui/
+    └── spec.md           # UI behavior and themes
+```
+
+Organize specs by domain — logical groupings that make sense for your system. Common patterns:
+
+- **By feature area**: `auth/`, `payments/`, `search/`
+- **By component**: `api/`, `frontend/`, `workers/`
+- **By bounded context**: `ordering/`, `fulfillment/`, `inventory/`
+
+### Spec Format
+
+A spec contains requirements, and each requirement has scenarios:
+
+```markdown
+# Auth Specification
+
+## Purpose
+Authentication and session management for the application.
+
+## Requirements
+
+### Requirement: User Authentication
+The system SHALL issue a JWT token upon successful login.
+
+#### Scenario: Valid credentials
+- GIVEN a user with valid credentials
+- WHEN the user submits login form
+- THEN a JWT token is returned
+- AND the user is redirected to dashboard
+
+#### Scenario: Invalid credentials
+- GIVEN invalid credentials
+- WHEN the user submits login form
+- THEN an error message is displayed
+- AND no token is issued
+
+### Requirement: Session Expiration
+The system MUST expire sessions after 30 minutes of inactivity.
+
+#### Scenario: Idle timeout
+- GIVEN an authenticated session
+- WHEN 30 minutes pass without activity
+- THEN the session is invalidated
+- AND the user must re-authenticate
+```
+
+**Key elements:**
+
+| Element | Purpose |
+|---------|---------|
+| `## Purpose` | High-level description of this spec's domain |
+| `### Requirement:` | A specific behavior the system must have |
+| `#### Scenario:` | A concrete example of the requirement in action |
+| SHALL/MUST/SHOULD | RFC 2119 keywords indicating requirement strength |
+
+### Why Structure Specs This Way
+
+**Requirements are the "what"** — they state what the system should do without specifying implementation.
+
+**Scenarios are the "when"** — they provide concrete examples that can be verified. Good scenarios:
+- Are testable (you could write an automated test for them)
+- Cover both happy path and edge cases
+- Use Given/When/Then or similar structured format
+
+**RFC 2119 keywords** (SHALL, MUST, SHOULD, MAY) communicate intent:
+- **MUST/SHALL** — absolute requirement
+- **SHOULD** — recommended, but exceptions exist
+- **MAY** — optional
+
+### What a Spec Is (and Is Not)
+
+A spec is a **behavior contract**, not an implementation plan.
+
+Good spec content:
+- Observable behavior users or downstream systems rely on
+- Inputs, outputs, and error conditions
+- External constraints (security, privacy, reliability, compatibility)
+- Scenarios that can be tested or explicitly validated
+
+Avoid in specs:
+- Internal class/function names
+- Library or framework choices
+- Step-by-step implementation details
+- Detailed execution plans (those belong in `design.md` or `tasks.md`)
+
+Quick test:
+- If implementation can change without changing externally visible behavior, it likely does not belong in the spec.
+
+### Keep It Lightweight: Progressive Rigor
+
+OpenSpec aims to avoid bureaucracy. Use the lightest level that still makes the change verifiable.
+
+**Lite spec (default):**
+- Short behavior-first requirements
+- Clear scope and non-goals
+- A few concrete acceptance checks
+
+**Full spec (for higher risk):**
+- Cross-team or cross-repo changes
+- API/contract changes, migrations, security/privacy concerns
+- Changes where ambiguity is likely to cause expensive rework
+
+Most changes should stay in Lite mode.
+
+### Human + Agent Collaboration
+
+In many teams, humans explore and agents draft artifacts. The intended loop is:
+
+1. Human provides intent, context, and constraints.
+2. Agent converts this into behavior-first requirements and scenarios.
+3. Agent keeps implementation detail in `design.md` and `tasks.md`, not `spec.md`.
+4. Validation confirms structure and clarity before implementation.
+
+This keeps specs readable for humans and consistent for agents.
+
+## Changes
+
+A change is a proposed modification to your system, packaged as a folder with everything needed to understand and implement it.
+
+### Change Structure
+
+```
+openspec/changes/add-dark-mode/
+├── proposal.md           # Why and what
+├── design.md             # How (technical approach)
+├── tasks.md              # Implementation checklist
+├── .openspec.yaml        # Change metadata (optional)
+└── specs/                # Delta specs
+    └── ui/
+        └── spec.md       # What's changing in ui/spec.md
+```
+
+Each change is self-contained. It has:
+- **Artifacts** — documents that capture intent, design, and tasks
+- **Delta specs** — specifications for what's being added, modified, or removed
+- **Metadata** — optional configuration for this specific change
+
+### Why Changes Are Folders
+
+Packaging a change as a folder has several benefits:
+
+1. **Everything together.** Proposal, design, tasks, and specs live in one place. No hunting through different locations.
+
+2. **Parallel work.** Multiple changes can exist simultaneously without conflicting. Work on `add-dark-mode` while `fix-auth-bug` is also in progress.
+
+3. **Clean history.** When archived, changes move to `changes/archive/` with their full context preserved. You can look back and understand not just what changed, but why.
+
+4. **Review-friendly.** A change folder is easy to review — open it, read the proposal, check the design, see the spec deltas.
+
+## Artifacts
+
+Artifacts are the documents within a change that guide the work.
+
+### The Artifact Flow
+
+```
+proposal ──────► specs ──────► design ──────► tasks ──────► implement
+    │               │             │              │
+   why            what           how          steps
+ + scope        changes       approach      to take
+```
+
+Artifacts build on each other. Each artifact provides context for the next.
+
+### Artifact Types
+
+#### Proposal (`proposal.md`)
+
+The proposal captures **intent**, **scope**, and **approach** at a high level.
+
+```markdown
+# Proposal: Add Dark Mode
+
+## Intent
+Users have requested a dark mode option to reduce eye strain
+during nighttime usage and match system preferences.
+
+## Scope
+In scope:
+- Theme toggle in settings
+- System preference detection
+- Persist preference in localStorage
+
+Out of scope:
+- Custom color themes (future work)
+- Per-page theme overrides
+
+## Approach
+Use CSS custom properties for theming with a React context
+for state management. Detect system preference on first load,
+allow manual override.
+```
+
+**When to update the proposal:**
+- Scope changes (narrowing or expanding)
+- Intent clarifies (better understanding of the problem)
+- Approach fundamentally shifts
+
+#### Specs (delta specs in `specs/`)
+
+Delta specs describe **what's changing** relative to the current specs. See [Delta Specs](#delta-specs) below.
+
+#### Design (`design.md`)
+
+The design captures **technical approach** and **architecture decisions**.
+
+```markdown
+# Design: Add Dark Mode
+
+## Technical Approach
+Theme state managed via React Context to avoid prop drilling.
+CSS custom properties enable runtime switching without class toggling.
+
+## Architecture Decisions
+
+### Decision: Context over Redux
+Using React Context for theme state because:
+- Simple binary state (light/dark)
+- No complex state transitions
+- Avoids adding Redux dependency
+
+### Decision: CSS Custom Properties
+Using CSS variables instead of CSS-in-JS because:
+- Works with existing stylesheet
+- No runtime overhead
+- Browser-native solution
+
+## Data Flow
+```
+ThemeProvider (context)
+       │
+       ▼
+ThemeToggle ◄──► localStorage
+       │
+       ▼
+CSS Variables (applied to :root)
+```
+
+## File Changes
+- `src/contexts/ThemeContext.tsx` (new)
+- `src/components/ThemeToggle.tsx` (new)
+- `src/styles/globals.css` (modified)
+```
+
+**When to update the design:**
+- Implementation reveals the approach won't work
+- Better solution discovered
+- Dependencies or constraints change
+
+#### Tasks (`tasks.md`)
+
+Tasks are the **implementation checklist** — concrete steps with checkboxes.
+
+```markdown
+# Tasks
+
+## 1. Theme Infrastructure
+- [ ] 1.1 Create ThemeContext with light/dark state
+- [ ] 1.2 Add CSS custom properties for colors
+- [ ] 1.3 Implement localStorage persistence
+- [ ] 1.4 Add system preference detection
+
+## 2. UI Components
+- [ ] 2.1 Create ThemeToggle component
+- [ ] 2.2 Add toggle to settings page
+- [ ] 2.3 Update Header to include quick toggle
+
+## 3. Styling
+- [ ] 3.1 Define dark theme color palette
+- [ ] 3.2 Update components to use CSS variables
+- [ ] 3.3 Test contrast ratios for accessibility
+```
+
+**Task best practices:**
+- Group related tasks under headings
+- Use hierarchical numbering (1.1, 1.2, etc.)
+- Keep tasks small enough to complete in one session
+- Check tasks off as you complete them
+
+## Delta Specs
+
+Delta specs are the key concept that makes OpenSpec work for brownfield development. They describe **what's changing** rather than restating the entire spec.
+
+### The Format
+
+```markdown
+# Delta for Auth
+
+## ADDED Requirements
+
+### Requirement: Two-Factor Authentication
+The system MUST support TOTP-based two-factor authentication.
+
+#### Scenario: 2FA enrollment
+- GIVEN a user without 2FA enabled
+- WHEN the user enables 2FA in settings
+- THEN a QR code is displayed for authenticator app setup
+- AND the user must verify with a code before activation
+
+#### Scenario: 2FA login
+- GIVEN a user with 2FA enabled
+- WHEN the user submits valid credentials
+- THEN an OTP challenge is presented
+- AND login completes only after valid OTP
+
+## MODIFIED Requirements
+
+### Requirement: Session Expiration
+The system MUST expire sessions after 15 minutes of inactivity.
+(Previously: 30 minutes)
+
+#### Scenario: Idle timeout
+- GIVEN an authenticated session
+- WHEN 15 minutes pass without activity
+- THEN the session is invalidated
+
+## REMOVED Requirements
+
+### Requirement: Remember Me
+(Deprecated in favor of 2FA. Users should re-authenticate each session.)
+```
+
+### Delta Sections
+
+| Section | Meaning | What Happens on Archive |
+|---------|---------|------------------------|
+| `## ADDED Requirements` | New behavior | Appended to main spec |
+| `## MODIFIED Requirements` | Changed behavior | Replaces existing requirement |
+| `## REMOVED Requirements` | Deprecated behavior | Deleted from main spec |
+
+### Why Deltas Instead of Full Specs
+
+**Clarity.** A delta shows exactly what's changing. Reading a full spec, you'd have to diff it mentally against the current version.
+
+**Conflict avoidance.** Two changes can touch the same spec file without conflicting, as long as they modify different requirements.
+
+**Review efficiency.** Reviewers see the change, not the unchanged context. Focus on what matters.
+
+**Brownfield fit.** Most work modifies existing behavior. Deltas make modifications first-class, not an afterthought.
+
+## Schemas
+
+Schemas define the artifact types and their dependencies for a workflow.
+
+### How Schemas Work
+
+```yaml
+# openspec/schemas/spec-driven/schema.yaml
+name: spec-driven
+artifacts:
+  - id: proposal
+    generates: proposal.md
+    requires: []              # No dependencies, can create first
+
+  - id: specs
+    generates: specs/**/*.md
+    requires: [proposal]      # Needs proposal before creating
+
+  - id: design
+    generates: design.md
+    requires: [proposal]      # Can create in parallel with specs
+
+  - id: tasks
+    generates: tasks.md
+    requires: [specs, design] # Needs both specs and design first
+```
+
+**Artifacts form a dependency graph:**
+
+```
+                    proposal
+                   (root node)
+                       │
+         ┌─────────────┴─────────────┐
+         │                           │
+         ▼                           ▼
+      specs                       design
+   (requires:                  (requires:
+    proposal)                   proposal)
+         │                           │
+         └─────────────┬─────────────┘
+                       │
+                       ▼
+                    tasks
+                (requires:
+                specs, design)
+```
+
+**Dependencies are enablers, not gates.** They show what's possible to create, not what you must create next. You can skip design if you don't need it. You can create specs before or after design — both depend only on proposal.
+
+### Built-in Schemas
+
+**spec-driven** (default)
+
+The standard workflow for spec-driven development:
+
+```
+proposal → specs → design → tasks → implement
+```
+
+Best for: Most feature work where you want to agree on specs before implementation.
+
+### Custom Schemas
+
+Create custom schemas for your team's workflow:
+
+```bash
+# Create from scratch
+openspec schema init research-first
+
+# Or fork an existing one
+openspec schema fork spec-driven research-first
+```
+
+**Example custom schema:**
+
+```yaml
+# openspec/schemas/research-first/schema.yaml
+name: research-first
+artifacts:
+  - id: research
+    generates: research.md
+    requires: []           # Do research first
+
+  - id: proposal
+    generates: proposal.md
+    requires: [research]   # Proposal informed by research
+
+  - id: tasks
+    generates: tasks.md
+    requires: [proposal]   # Skip specs/design, go straight to tasks
+```
+
+See [Customization](customization.md) for full details on creating and using custom schemas.
+
+## Archive
+
+Archiving completes a change by merging its delta specs into the main specs and preserving the change for history.
+
+### What Happens When You Archive
+
+```
+Before archive:
+
+openspec/
+├── specs/
+│   └── auth/
+│       └── spec.md ◄────────────────┐
+└── changes/                         │
+    └── add-2fa/                     │
+        ├── proposal.md              │
+        ├── design.md                │ merge
+        ├── tasks.md                 │
+        └── specs/                   │
+            └── auth/                │
+                └── spec.md ─────────┘
+
+
+After archive:
+
+openspec/
+├── specs/
+│   └── auth/
+│       └── spec.md        # Now includes 2FA requirements
+└── changes/
+    └── archive/
+        └── 2025-01-24-add-2fa/    # Preserved for history
+            ├── proposal.md
+            ├── design.md
+            ├── tasks.md
+            └── specs/
+                └── auth/
+                    └── spec.md
+```
+
+### The Archive Process
+
+1. **Merge deltas.** Each delta spec section (ADDED/MODIFIED/REMOVED) is applied to the corresponding main spec.
+
+2. **Move to archive.** The change folder moves to `changes/archive/` with a date prefix for chronological ordering.
+
+3. **Preserve context.** All artifacts remain intact in the archive. You can always look back to understand why a change was made.
+
+### Why Archive Matters
+
+**Clean state.** Active changes (`changes/`) shows only work in progress. Completed work moves out of the way.
+
+**Audit trail.** The archive preserves the full context of every change — not just what changed, but the proposal explaining why, the design explaining how, and the tasks showing the work done.
+
+**Spec evolution.** Specs grow organically as changes are archived. Each archive merges its deltas, building up a comprehensive specification over time.

+# Customization
+
+OpenSpec provides three levels of customization:
+
+| Level | What it does | Best for |
+|-------|--------------|----------|
+| **Project Config** | Set defaults, inject context/rules | Most teams |
+| **Custom Schemas** | Define your own workflow artifacts | Teams with unique processes |
+| **Global Overrides** | Share schemas across all projects | Power users |
+
+---
+
+## Project Configuration
+
+The `openspec/config.yaml` file is the easiest way to customize OpenSpec for your team. It lets you:
+
+- **Set a default schema** - Skip `--schema` on every command
+- **Inject project context** - AI sees your tech stack, conventions, etc.
+- **Add per-artifact rules** - Custom rules for specific artifacts
+
+### Quick Setup
+
+```bash
+openspec init
+```
+
+This walks you through creating a config interactively. Or create one manually:
+
+```yaml
+# openspec/config.yaml
+schema: spec-driven
+
+context: |
+  Tech stack: TypeScript, React, Node.js, PostgreSQL
+  API style: RESTful, documented in docs/api.md
+  Testing: Jest + React Testing Library
+  We value backwards compatibility for all public APIs
+
+rules:
+  proposal:
+    - Include rollback plan
+    - Identify affected teams
+  specs:
+    - Use Given/When/Then format
+    - Reference existing patterns before inventing new ones
+```
+
+### How It Works
+
+**Default schema:**
+
+```bash
+# Without config
+openspec new change my-feature --schema spec-driven
+
+# With config - schema is automatic
+openspec new change my-feature
+```
+
+**Context and rules injection:**
+
+When generating any artifact, your context and rules are injected into the AI prompt:
+
+```xml
+<context>
+Tech stack: TypeScript, React, Node.js, PostgreSQL
+...
+</context>
+
+<rules>
+- Include rollback plan
+- Identify affected teams
+</rules>
+
+<template>
+[Schema's built-in template]
+</template>
+```
+
+- **Context** appears in ALL artifacts
+- **Rules** ONLY appear for the matching artifact
+
+### Schema Resolution Order
+
+When OpenSpec needs a schema, it checks in this order:
+
+1. CLI flag: `--schema <name>`
+2. Change metadata (`.openspec.yaml` in the change folder)
+3. Project config (`openspec/config.yaml`)
+4. Default (`spec-driven`)
+
+---
+
+## Custom Schemas
+
+When project config isn't enough, create your own schema with a completely custom workflow. Custom schemas live in your project's `openspec/schemas/` directory and are version-controlled with your code.
+
+```text
+your-project/
+├── openspec/
+│   ├── config.yaml        # Project config
+│   ├── schemas/           # Custom schemas live here
+│   │   └── my-workflow/
+│   │       ├── schema.yaml
+│   │       └── templates/
+│   └── changes/           # Your changes
+└── src/
+```
+
+### Fork an Existing Schema
+
+The fastest way to customize is to fork a built-in schema:
+
+```bash
+openspec schema fork spec-driven my-workflow
+```
+
+This copies the entire `spec-driven` schema to `openspec/schemas/my-workflow/` where you can edit it freely.
+
+**What you get:**
+
+```text
+openspec/schemas/my-workflow/
+├── schema.yaml           # Workflow definition
+└── templates/
+    ├── proposal.md       # Template for proposal artifact
+    ├── spec.md           # Template for specs
+    ├── design.md         # Template for design
+    └── tasks.md          # Template for tasks
+```
+
+Now edit `schema.yaml` to change the workflow, or edit templates to change what AI generates.
+
+### Create a Schema from Scratch
+
+For a completely fresh workflow:
+
+```bash
+# Interactive
+openspec schema init research-first
+
+# Non-interactive
+openspec schema init rapid \
+  --description "Rapid iteration workflow" \
+  --artifacts "proposal,tasks" \
+  --default
+```
+
+### Schema Structure
+
+A schema defines the artifacts in your workflow and how they depend on each other:
+
+```yaml
+# openspec/schemas/my-workflow/schema.yaml
+name: my-workflow
+version: 1
+description: My team's custom workflow
+
+artifacts:
+  - id: proposal
+    generates: proposal.md
+    description: Initial proposal document
+    template: proposal.md
+    instruction: |
+      Create a proposal that explains WHY this change is needed.
+      Focus on the problem, not the solution.
+    requires: []
+
+  - id: design
+    generates: design.md
+    description: Technical design
+    template: design.md
+    instruction: |
+      Create a design document explaining HOW to implement.
+    requires:
+      - proposal    # Can't create design until proposal exists
+
+  - id: tasks
+    generates: tasks.md
+    description: Implementation checklist
+    template: tasks.md
+    requires:
+      - design
+
+apply:
+  requires: [tasks]
+  tracks: tasks.md
+```
+
+**Key fields:**
+
+| Field | Purpose |
+|-------|---------|
+| `id` | Unique identifier, used in commands and rules |
+| `generates` | Output filename (supports globs like `specs/**/*.md`) |
+| `template` | Template file in `templates/` directory |
+| `instruction` | AI instructions for creating this artifact |
+| `requires` | Dependencies - which artifacts must exist first |
+
+### Templates
+
+Templates are markdown files that guide the AI. They're injected into the prompt when creating that artifact.
+
+```markdown
+<!-- templates/proposal.md -->
+## Why
+
+<!-- Explain the motivation for this change. What problem does this solve? -->
+
+## What Changes
+
+<!-- Describe what will change. Be specific about new capabilities or modifications. -->
+
+## Impact
+
+<!-- Affected code, APIs, dependencies, systems -->
+```
+
+Templates can include:
+- Section headers the AI should fill in
+- HTML comments with guidance for the AI
+- Example formats showing expected structure
+
+### Validate Your Schema
+
+Before using a custom schema, validate it:
+
+```bash
+openspec schema validate my-workflow
+```
+
+This checks:
+- `schema.yaml` syntax is correct
+- All referenced templates exist
+- No circular dependencies
+- Artifact IDs are valid
+
+### Use Your Custom Schema
+
+Once created, use your schema with:
+
+```bash
+# Specify on command
+openspec new change feature --schema my-workflow
+
+# Or set as default in config.yaml
+schema: my-workflow
+```
+
+### Debug Schema Resolution
+
+Not sure which schema is being used? Check with:
+
+```bash
+# See where a specific schema resolves from
+openspec schema which my-workflow
+
+# List all available schemas
+openspec schema which --all
+```
+
+Output shows whether it's from your project, user directory, or the package:
+
+```text
+Schema: my-workflow
+Source: project
+Path: /path/to/project/openspec/schemas/my-workflow
+```
+
+---
+
+> **Note:** OpenSpec also supports user-level schemas at `~/.local/share/openspec/schemas/` for sharing across projects, but project-level schemas in `openspec/schemas/` are recommended since they're version-controlled with your code.
+
+---
+
+## Examples
+
+### Rapid Iteration Workflow
+
+A minimal workflow for quick iterations:
+
+```yaml
+# openspec/schemas/rapid/schema.yaml
+name: rapid
+version: 1
+description: Fast iteration with minimal overhead
+
+artifacts:
+  - id: proposal
+    generates: proposal.md
+    description: Quick proposal
+    template: proposal.md
+    instruction: |
+      Create a brief proposal for this change.
+      Focus on what and why, skip detailed specs.
+    requires: []
+
+  - id: tasks
+    generates: tasks.md
+    description: Implementation checklist
+    template: tasks.md
+    requires: [proposal]
+
+apply:
+  requires: [tasks]
+  tracks: tasks.md
+```
+
+### Adding a Review Artifact
+
+Fork the default and add a review step:
+
+```bash
+openspec schema fork spec-driven with-review
+```
+
+Then edit `schema.yaml` to add:
+
+```yaml
+  - id: review
+    generates: review.md
+    description: Pre-implementation review checklist
+    template: review.md
+    instruction: |
+      Create a review checklist based on the design.
+      Include security, performance, and testing considerations.
+    requires:
+      - design
+
+  - id: tasks
+    # ... existing tasks config ...
+    requires:
+      - specs
+      - design
+      - review    # Now tasks require review too
+```

+# Getting Started
+
+This guide explains how OpenSpec works after you've installed and initialized it. For installation instructions, see the [main README](../README.md#quick-start).
+
+## How It Works
+
+OpenSpec helps you and your AI coding assistant agree on what to build before any code is written. The workflow follows a simple pattern:
+
+```
+┌────────────────────┐
+│ Start a Change     │  /opsx:new
+└────────┬───────────┘
+         │
+         ▼
+┌────────────────────┐
+│ Create Artifacts   │  /opsx:ff or /opsx:continue
+│ (proposal, specs,  │
+│  design, tasks)    │
+└────────┬───────────┘
+         │
+         ▼
+┌────────────────────┐
+│ Implement Tasks    │  /opsx:apply
+│ (AI writes code)   │
+└────────┬───────────┘
+         │
+         ▼
+┌────────────────────┐
+│ Archive & Merge    │  /opsx:archive
+│ Specs              │
+└────────────────────┘
+```
+
+## What OpenSpec Creates
+
+After running `openspec init`, your project has this structure:
+
+```
+openspec/
+├── specs/              # Source of truth (your system's behavior)
+│   └── <domain>/
+│       └── spec.md
+├── changes/            # Proposed updates (one folder per change)
+│   └── <change-name>/
+│       ├── proposal.md
+│       ├── design.md
+│       ├── tasks.md
+│       └── specs/      # Delta specs (what's changing)
+│           └── <domain>/
+│               └── spec.md
+└── config.yaml         # Project configuration (optional)
+```
+
+**Two key directories:**
+
+- **`specs/`** - The source of truth. These specs describe how your system currently behaves. Organized by domain (e.g., `specs/auth/`, `specs/payments/`).
+
+- **`changes/`** - Proposed modifications. Each change gets its own folder with all related artifacts. When a change is complete, its specs merge into the main `specs/` directory.
+
+## Understanding Artifacts
+
+Each change folder contains artifacts that guide the work:
+
+| Artifact | Purpose |
+|----------|---------|
+| `proposal.md` | The "why" and "what" - captures intent, scope, and approach |
+| `specs/` | Delta specs showing ADDED/MODIFIED/REMOVED requirements |
+| `design.md` | The "how" - technical approach and architecture decisions |
+| `tasks.md` | Implementation checklist with checkboxes |
+
+**Artifacts build on each other:**
+
+```
+proposal ──► specs ──► design ──► tasks ──► implement
+   ▲           ▲          ▲                    │
+   └───────────┴──────────┴────────────────────┘
+            update as you learn
+```
+
+You can always go back and refine earlier artifacts as you learn more during implementation.
+
+## How Delta Specs Work
+
+Delta specs are the key concept in OpenSpec. They show what's changing relative to your current specs.
+
+### The Format
+
+Delta specs use sections to indicate the type of change:
+
+```markdown
+# Delta for Auth
+
+## ADDED Requirements
+
+### Requirement: Two-Factor Authentication
+The system MUST require a second factor during login.
+
+#### Scenario: OTP required
+- GIVEN a user with 2FA enabled
+- WHEN the user submits valid credentials
+- THEN an OTP challenge is presented
+
+## MODIFIED Requirements
+
+### Requirement: Session Timeout
+The system SHALL expire sessions after 30 minutes of inactivity.
+(Previously: 60 minutes)
+
+#### Scenario: Idle timeout
+- GIVEN an authenticated session
+- WHEN 30 minutes pass without activity
+- THEN the session is invalidated
+
+## REMOVED Requirements
+
+### Requirement: Remember Me
+(Deprecated in favor of 2FA)
+```
+
+### What Happens on Archive
+
+When you archive a change:
+
+1. **ADDED** requirements are appended to the main spec
+2. **MODIFIED** requirements replace the existing version
+3. **REMOVED** requirements are deleted from the main spec
+
+The change folder moves to `openspec/changes/archive/` for audit history.
+
+## Example: Your First Change
+
+Let's walk through adding dark mode to an application.
+
+### 1. Start the Change
+
+```
+You: /opsx:new add-dark-mode
+
+AI:  Created openspec/changes/add-dark-mode/
+     Ready to create: proposal
+```
+
+### 2. Create Artifacts
+
+Use `/opsx:ff` (fast-forward) to create all planning artifacts at once:
+
+```
+You: /opsx:ff
+
+AI:  Creating artifacts for add-dark-mode...
+     ✓ proposal.md — why we're doing this, what's changing
+     ✓ specs/       — requirements and scenarios
+     ✓ design.md    — technical approach
+     ✓ tasks.md     — implementation checklist
+     Ready for implementation!
+```
+
+### 3. What Gets Created
+
+**proposal.md** - Captures the intent:
+
+```markdown
+# Proposal: Add Dark Mode
+
+## Intent
+Users have requested a dark mode option to reduce eye strain
+during nighttime usage.
+
+## Scope
+- Add theme toggle in settings
+- Support system preference detection
+- Persist preference in localStorage
+
+## Approach
+Use CSS custom properties for theming with a React context
+for state management.
+```
+
+**specs/ui/spec.md** - Delta showing new requirements:
+
+```markdown
+# Delta for UI
+
+## ADDED Requirements
+
+### Requirement: Theme Selection
+The system SHALL allow users to choose between light and dark themes.
+
+#### Scenario: Manual toggle
+- GIVEN a user on any page
+- WHEN the user clicks the theme toggle
+- THEN the theme switches immediately
+- AND the preference persists across sessions
+
+#### Scenario: System preference
+- GIVEN a user with no saved preference
+- WHEN the application loads
+- THEN the system's preferred color scheme is used
+```
+
+**tasks.md** - Implementation checklist:
+
+```markdown
+# Tasks
+
+## 1. Theme Infrastructure
+- [ ] 1.1 Create ThemeContext with light/dark state
+- [ ] 1.2 Add CSS custom properties for colors
+- [ ] 1.3 Implement localStorage persistence
+
+## 2. UI Components
+- [ ] 2.1 Create ThemeToggle component
+- [ ] 2.2 Add toggle to settings page
+- [ ] 2.3 Update Header to include quick toggle
+
+## 3. Styling
+- [ ] 3.1 Define dark theme color palette
+- [ ] 3.2 Update components to use CSS variables
+```
+
+### 4. Implement
+
+```
+You: /opsx:apply
+
+AI:  Working through tasks...
+     ✓ 1.1 Created ThemeContext with light/dark state
+     ✓ 1.2 Added CSS custom properties to globals.css
+     ✓ 1.3 Implemented localStorage persistence
+     ✓ 2.1 Created ThemeToggle component
+     ...
+     All tasks complete!
+```
+
+During implementation, if you discover the design needs adjustment, just update the artifact and continue.
+
+### 5. Archive
+
+```
+You: /opsx:archive
+
+AI:  Archiving add-dark-mode...
+     ✓ Merged specs into openspec/specs/ui/spec.md
+     ✓ Moved to openspec/changes/archive/2025-01-24-add-dark-mode/
+     Done! Ready for the next feature.
+```
+
+Your delta specs are now part of the main specs, documenting how your system works.
+
+## Verifying and Reviewing
+
+Use the CLI to check on your changes:
+
+```bash
+# List active changes
+openspec list
+
+# View change details
+openspec show add-dark-mode
+
+# Validate spec formatting
+openspec validate add-dark-mode
+
+# Interactive dashboard
+openspec view
+```

+# Migrating to OPSX
+
+This guide helps you transition from the legacy OpenSpec workflow to OPSX. The migration is designed to be smooth—your existing work is preserved, and the new system offers more flexibility.
+
+## What's Changing?
+
+OPSX replaces the old phase-locked workflow with a fluid, action-based approach. Here's the key shift:
+
+| Aspect | Legacy | OPSX |
+|--------|--------|------|
+| **Commands** | `/openspec:proposal`, `/openspec:apply`, `/openspec:archive` | `/opsx:new`, `/opsx:continue`, `/opsx:apply`, and more |
+| **Workflow** | Create all artifacts at once | Create incrementally or all at once—your choice |
+| **Going back** | Awkward phase gates | Natural—update any artifact anytime |
+| **Customization** | Fixed structure | Schema-driven, fully hackable |
+| **Configuration** | `CLAUDE.md` with markers + `project.md` | Clean config in `openspec/config.yaml` |
+
+**The philosophy change:** Work isn't linear. OPSX stops pretending it is.
+
+---
+
+## Before You Begin
+
+### Your Existing Work Is Safe
+
+The migration process is designed with preservation in mind:
+
+- **Active changes in `openspec/changes/`** — Completely preserved. You can continue them with OPSX commands.
+- **Archived changes** — Untouched. Your history remains intact.
+- **Main specs in `openspec/specs/`** — Untouched. These are your source of truth.
+- **Your content in CLAUDE.md, AGENTS.md, etc.** — Preserved. Only the OpenSpec marker blocks are removed; everything you wrote stays.
+
+### What Gets Removed
+
+Only OpenSpec-managed files that are being replaced:
+
+| What | Why |
+|------|-----|
+| Legacy slash command directories/files | Replaced by the new skills system |
+| `openspec/AGENTS.md` | Obsolete workflow trigger |
+| OpenSpec markers in `CLAUDE.md`, `AGENTS.md`, etc. | No longer needed |
+
+**Legacy command locations by tool** (examples—your tool may vary):
+
+- Claude Code: `.claude/commands/openspec/`
+- Cursor: `.cursor/commands/openspec-*.md`
+- Windsurf: `.windsurf/workflows/openspec-*.md`
+- Cline: `.clinerules/workflows/openspec-*.md`
+- Roo: `.roo/commands/openspec-*.md`
+- GitHub Copilot: `.github/prompts/openspec-*.prompt.md` (IDE extensions only; not supported in Copilot CLI)
+- And others (Augment, Continue, Amazon Q, etc.)
+
+The migration detects whichever tools you have configured and cleans up their legacy files.
+
+The removal list may seem long, but these are all files that OpenSpec originally created. Your own content is never deleted.
+
+### What Needs Your Attention
+
+One file requires manual migration:
+
+**`openspec/project.md`** — This file isn't deleted automatically because it may contain project context you've written. You'll need to:
+
+1. Review its contents
+2. Move useful context to `openspec/config.yaml` (see guidance below)
+3. Delete the file when ready
+
+**Why we made this change:**
+
+The old `project.md` was passive—agents might read it, might not, might forget what they read. We found reliability was inconsistent.
+
+The new `config.yaml` context is **actively injected into every OpenSpec planning request**. This means your project conventions, tech stack, and rules are always present when the AI is creating artifacts. Higher reliability.
+
+**The tradeoff:**
+
+Because context is injected into every request, you'll want to be concise. Focus on what really matters:
+- Tech stack and key conventions
+- Non-obvious constraints the AI needs to know
+- Rules that frequently got ignored before
+
+Don't worry about getting it perfect. We're still learning what works best here, and we'll be improving how context injection works as we experiment.
+
+---
+
+## Running the Migration
+
+Both `openspec init` and `openspec update` detect legacy files and guide you through the same cleanup process. Use whichever fits your situation:
+
+### Using `openspec init`
+
+Run this if you want to add new tools or reconfigure which tools are set up:
+
+```bash
+openspec init
+```
+
+The init command detects legacy files and guides you through cleanup:
+
+```
+Upgrading to the new OpenSpec
+
+OpenSpec now uses agent skills, the emerging standard across coding
+agents. This simplifies your setup while keeping everything working
+as before.
+
+Files to remove
+No user content to preserve:
+  • .claude/commands/openspec/
+  • openspec/AGENTS.md
+
+Files to update
+OpenSpec markers will be removed, your content preserved:
+  • CLAUDE.md
+  • AGENTS.md
+
+Needs your attention
+  • openspec/project.md
+    We won't delete this file. It may contain useful project context.
+
+    The new openspec/config.yaml has a "context:" section for planning
+    context. This is included in every OpenSpec request and works more
+    reliably than the old project.md approach.
+
+    Review project.md, move any useful content to config.yaml's context
+    section, then delete the file when ready.
+
+? Upgrade and clean up legacy files? (Y/n)
+```
+
+**What happens when you say yes:**
+
+1. Legacy slash command directories are removed
+2. OpenSpec markers are stripped from `CLAUDE.md`, `AGENTS.md`, etc. (your content stays)
+3. `openspec/AGENTS.md` is deleted
+4. New skills are installed in `.claude/skills/`
+5. `openspec/config.yaml` is created with a default schema
+
+### Using `openspec update`
+
+Run this if you just want to migrate and refresh your existing tools to the latest version:
+
+```bash
+openspec update
+```
+
+The update command also detects and cleans up legacy artifacts, then refreshes your skills to the latest version.
+
+### Non-Interactive / CI Environments
+
+For scripted migrations:
+
+```bash
+openspec init --force --tools claude
+```
+
+The `--force` flag skips prompts and auto-accepts cleanup.
+
+---
+
+## Migrating project.md to config.yaml
+
+The old `openspec/project.md` was a freeform markdown file for project context. The new `openspec/config.yaml` is structured and—critically—**injected into every planning request** so your conventions are always present when the AI works.
+
+### Before (project.md)
+
+```markdown
+# Project Context
+
+This is a TypeScript monorepo using React and Node.js.
+We use Jest for testing and follow strict ESLint rules.
+Our API is RESTful and documented in docs/api.md.
+
+## Conventions
+
+- All public APIs must maintain backwards compatibility
+- New features should include tests
+- Use Given/When/Then format for specifications
+```
+
+### After (config.yaml)
+
+```yaml
+schema: spec-driven
+
+context: |
+  Tech stack: TypeScript, React, Node.js
+  Testing: Jest with React Testing Library
+  API: RESTful, documented in docs/api.md
+  We maintain backwards compatibility for all public APIs
+
+rules:
+  proposal:
+    - Include rollback plan for risky changes
+  specs:
+    - Use Given/When/Then format for scenarios
+    - Reference existing patterns before inventing new ones
+  design:
+    - Include sequence diagrams for complex flows
+```
+
+### Key Differences
+
+| project.md | config.yaml |
+|------------|-------------|
+| Freeform markdown | Structured YAML |
+| One blob of text | Separate context and per-artifact rules |
+| Unclear when it's used | Context appears in ALL artifacts; rules appear in matching artifacts only |
+| No schema selection | Explicit `schema:` field sets default workflow |
+
+### What to Keep, What to Drop
+
+When migrating, be selective. Ask yourself: "Does the AI need this for *every* planning request?"
+
+**Good candidates for `context:`**
+- Tech stack (languages, frameworks, databases)
+- Key architectural patterns (monorepo, microservices, etc.)
+- Non-obvious constraints ("we can't use library X because...")
+- Critical conventions that often get ignored
+
+**Move to `rules:` instead**
+- Artifact-specific formatting ("use Given/When/Then in specs")
+- Review criteria ("proposals must include rollback plans")
+- These only appear for the matching artifact, keeping other requests lighter
+
+**Leave out entirely**
+- General best practices the AI already knows
+- Verbose explanations that could be summarized
+- Historical context that doesn't affect current work
+
+### Migration Steps
+
+1. **Create config.yaml** (if not already created by init):
+   ```yaml
+   schema: spec-driven
+   ```
+
+2. **Add your context** (be concise—this goes into every request):
+   ```yaml
+   context: |
+     Your project background goes here.
+     Focus on what the AI genuinely needs to know.
+   ```
+
+3. **Add per-artifact rules** (optional):
+   ```yaml
+   rules:
+     proposal:
+       - Your proposal-specific guidance
+     specs:
+       - Your spec-writing rules
+   ```
+
+4. **Delete project.md** once you've moved everything useful.
+
+**Don't overthink it.** Start with the essentials and iterate. If you notice the AI missing something important, add it. If context feels bloated, trim it. This is a living document.
+
+### Need Help? Use This Prompt
+
+If you're unsure how to distill your project.md, ask your AI assistant:
+
+```
+I'm migrating from OpenSpec's old project.md to the new config.yaml format.
+
+Here's my current project.md:
+[paste your project.md content]
+
+Please help me create a config.yaml with:
+1. A concise `context:` section (this gets injected into every planning request, so keep it tight—focus on tech stack, key constraints, and conventions that often get ignored)
+2. `rules:` for specific artifacts if any content is artifact-specific (e.g., "use Given/When/Then" belongs in specs rules, not global context)
+
+Leave out anything generic that AI models already know. Be ruthless about brevity.
+```
+
+The AI will help you identify what's essential vs. what can be trimmed.
+
+---
+
+## The New Commands
+
+After migration, you have 9 OPSX commands instead of 3:
+
+| Command | Purpose |
+|---------|---------|
+| `/opsx:explore` | Think through ideas with no structure |
+| `/opsx:new` | Start a new change |
+| `/opsx:continue` | Create the next artifact (one at a time) |
+| `/opsx:ff` | Fast-forward—create all planning artifacts at once |
+| `/opsx:apply` | Implement tasks from tasks.md |
+| `/opsx:verify` | Validate implementation matches specs |
+| `/opsx:sync` | Preview spec merge (optional—archive prompts if needed) |
+| `/opsx:archive` | Finalize and archive the change |
+| `/opsx:bulk-archive` | Archive multiple changes at once |
+
+### Command Mapping from Legacy
+
+| Legacy | OPSX Equivalent |
+|--------|-----------------|
+| `/openspec:proposal` | `/opsx:new` then `/opsx:ff` |
+| `/openspec:apply` | `/opsx:apply` |
+| `/openspec:archive` | `/opsx:archive` |
+
+### New Capabilities
+
+**Granular artifact creation:**
+```
+/opsx:continue
+```
+Creates one artifact at a time based on dependencies. Use this when you want to review each step.
+
+**Exploration mode:**
+```
+/opsx:explore
+```
+Think through ideas with a partner before committing to a change.
+
+---
+
+## Understanding the New Architecture
+
+### From Phase-Locked to Fluid
+
+The legacy workflow forced linear progression:
+
+```
+┌──────────────┐      ┌──────────────┐      ┌──────────────┐
+│   PLANNING   │ ───► │ IMPLEMENTING │ ───► │   ARCHIVING  │
+│    PHASE     │      │    PHASE     │      │    PHASE     │
+└──────────────┘      └──────────────┘      └──────────────┘
+
+If you're in implementation and realize the design is wrong?
+Too bad. Phase gates don't let you go back easily.
+```
+
+OPSX uses actions, not phases:
+
+```
+         ┌───────────────────────────────────────────────┐
+         │           ACTIONS (not phases)                │
+         │                                               │
+         │     new ◄──► continue ◄──► apply ◄──► archive │
+         │      │          │           │             │   │
+         │      └──────────┴───────────┴─────────────┘   │
+         │                    any order                  │
+         └───────────────────────────────────────────────┘
+```
+
+### Dependency Graph
+
+Artifacts form a directed graph. Dependencies are enablers, not gates:
+
+```
+                        proposal
+                       (root node)
+                            │
+              ┌─────────────┴─────────────┐
+              │                           │
+              ▼                           ▼
+           specs                       design
+        (requires:                  (requires:
+         proposal)                   proposal)
+              │                           │
+              └─────────────┬─────────────┘
+                            │
+                            ▼
+                         tasks
+                     (requires:
+                     specs, design)
+```
+
+When you run `/opsx:continue`, it checks what's ready and offers the next artifact. You can also create multiple ready artifacts in any order.
+
+### Skills vs Commands
+
+The legacy system used tool-specific command files:
+
+```
+.claude/commands/openspec/
+├── proposal.md
+├── apply.md
+└── archive.md
+```
+
+OPSX uses the emerging **skills** standard:
+
+```
+.claude/skills/
+├── openspec-explore/SKILL.md
+├── openspec-new-change/SKILL.md
+├── openspec-continue-change/SKILL.md
+├── openspec-apply-change/SKILL.md
+└── ...
+```
+
+Skills are recognized across multiple AI coding tools and provide richer metadata.
+
+---
+
+## Continuing Existing Changes
+
+Your in-progress changes work seamlessly with OPSX commands.
+
+**Have an active change from the legacy workflow?**
+
+```
+/opsx:apply add-my-feature
+```
+
+OPSX reads the existing artifacts and continues from where you left off.
+
+**Want to add more artifacts to an existing change?**
+
+```
+/opsx:continue add-my-feature
+```
+
+Shows what's ready to create based on what already exists.
+
+**Need to see status?**
+
+```bash
+openspec status --change add-my-feature
+```
+
+---
+
+## The New Config System
+
+### config.yaml Structure
+
+```yaml
+# Required: Default schema for new changes
+schema: spec-driven
+
+# Optional: Project context (max 50KB)
+# Injected into ALL artifact instructions
+context: |
+  Your project background, tech stack,
+  conventions, and constraints.
+
+# Optional: Per-artifact rules
+# Only injected into matching artifacts
+rules:
+  proposal:
+    - Include rollback plan
+  specs:
+    - Use Given/When/Then format
+  design:
+    - Document fallback strategies
+  tasks:
+    - Break into 2-hour maximum chunks
+```
+
+### Schema Resolution
+
+When determining which schema to use, OPSX checks in order:
+
+1. **CLI flag**: `--schema <name>` (highest priority)
+2. **Change metadata**: `.openspec.yaml` in the change directory
+3. **Project config**: `openspec/config.yaml`
+4. **Default**: `spec-driven`
+
+### Available Schemas
+
+| Schema | Artifacts | Best For |
+|--------|-----------|----------|
+| `spec-driven` | proposal → specs → design → tasks | Most projects |
+
+List all available schemas:
+
+```bash
+openspec schemas
+```
+
+### Custom Schemas
+
+Create your own workflow:
+
+```bash
+openspec schema init my-workflow
+```
+
+Or fork an existing one:
+
+```bash
+openspec schema fork spec-driven my-workflow
+```
+
+See [Customization](customization.md) for details.
+
+---
+
+## Troubleshooting
+
+### "Legacy files detected in non-interactive mode"
+
+You're running in a CI or non-interactive environment. Use:
+
+```bash
+openspec init --force
+```
+
+### Commands not appearing after migration
+
+Restart your IDE. Skills are detected at startup.
+
+### "Unknown artifact ID in rules"
+
+Check that your `rules:` keys match your schema's artifact IDs:
+
+- **spec-driven**: `proposal`, `specs`, `design`, `tasks`
+
+Run this to see valid artifact IDs:
+
+```bash
+openspec schemas --json
+```
+
+### Config not being applied
+
+1. Ensure the file is at `openspec/config.yaml` (not `.yml`)
+2. Validate YAML syntax
+3. Config changes take effect immediately—no restart needed
+
+### project.md not migrated
+
+The system intentionally preserves `project.md` because it may contain your custom content. Review it manually, move useful parts to `config.yaml`, then delete it.
+
+### Want to see what would be cleaned up?
+
+Run init and decline the cleanup prompt—you'll see the full detection summary without any changes being made.

+# Multi-Language Guide
+
+Configure OpenSpec to generate artifacts in languages other than English.
+
+## Quick Setup
+
+Add a language instruction to your `openspec/config.yaml`:
+
+```yaml
+schema: spec-driven
+
+context: |
+  Language: Portuguese (pt-BR)
+  All artifacts must be written in Brazilian Portuguese.
+
+  # Your other project context below...
+  Tech stack: TypeScript, React, Node.js
+```
+
+That's it. All generated artifacts will now be in Portuguese.
+
+## Language Examples
+
+### Portuguese (Brazil)
+
+```yaml
+context: |
+  Language: Portuguese (pt-BR)
+  All artifacts must be written in Brazilian Portuguese.
+```
+
+### Spanish
+
+```yaml
+context: |
+  Idioma: Español
+  Todos los artefactos deben escribirse en español.
+```
+
+### Chinese (Simplified)
+
+```yaml
+context: |
+  语言：中文（简体）
+  所有产出物必须用简体中文撰写。
+```
+
+### Japanese
+
+```yaml
+context: |
+  言語：日本語
+  すべての成果物は日本語で作成してください。
+```
+
+### French
+
+```yaml
+context: |
+  Langue : Français
+  Tous les artefacts doivent être rédigés en français.
+```
+
+### German
+
+```yaml
+context: |
+  Sprache: Deutsch
+  Alle Artefakte müssen auf Deutsch verfasst werden.
+```
+
+## Tips
+
+### Handle Technical Terms
+
+Decide how to handle technical terminology:
+
+```yaml
+context: |
+  Language: Japanese
+  Write in Japanese, but:
+  - Keep technical terms like "API", "REST", "GraphQL" in English
+  - Code examples and file paths remain in English
+```
+
+### Combine with Other Context
+
+Language settings work alongside your other project context:
+
+```yaml
+schema: spec-driven
+
+context: |
+  Language: Portuguese (pt-BR)
+  All artifacts must be written in Brazilian Portuguese.
+
+  Tech stack: TypeScript, React 18, Node.js 20
+  Database: PostgreSQL with Prisma ORM
+```
+
+## Verification
+
+To verify your language config is working:
+
+```bash
+# Check the instructions - should show your language context
+openspec instructions proposal --change my-change
+
+# Output will include your language context
+```

+# OPSX Workflow
+
+> Feedback welcome on [Discord](https://discord.gg/YctCnvvshC).
+
+## What Is It?
+
+OPSX is now the standard workflow for OpenSpec.
+
+It's a **fluid, iterative workflow** for OpenSpec changes. No more rigid phases — just actions you can take anytime.
+
+## Why This Exists
+
+The legacy OpenSpec workflow works, but it's **locked down**:
+
+- **Instructions are hardcoded** — buried in TypeScript, you can't change them
+- **All-or-nothing** — one big command creates everything, can't test individual pieces
+- **Fixed structure** — same workflow for everyone, no customization
+- **Black box** — when AI output is bad, you can't tweak the prompts
+
+**OPSX opens it up.** Now anyone can:
+
+1. **Experiment with instructions** — edit a template, see if the AI does better
+2. **Test granularly** — validate each artifact's instructions independently
+3. **Customize workflows** — define your own artifacts and dependencies
+4. **Iterate quickly** — change a template, test immediately, no rebuild
+
+```
+Legacy workflow:                      OPSX:
+┌────────────────────────┐           ┌────────────────────────┐
+│  Hardcoded in package  │           │  schema.yaml           │◄── You edit this
+│  (can't change)        │           │  templates/*.md        │◄── Or this
+│        ↓               │           │        ↓               │
+│  Wait for new release  │           │  Instant effect        │
+│        ↓               │           │        ↓               │
+│  Hope it's better      │           │  Test it yourself      │
+└────────────────────────┘           └────────────────────────┘
+```
+
+**This is for everyone:**
+- **Teams** — create workflows that match how you actually work
+- **Power users** — tweak prompts to get better AI outputs for your codebase
+- **OpenSpec contributors** — experiment with new approaches without releases
+
+We're all still learning what works best. OPSX lets us learn together.
+
+## The User Experience
+
+**The problem with linear workflows:**
+You're "in planning phase", then "in implementation phase", then "done". But real work doesn't work that way. You implement something, realize your design was wrong, need to update specs, continue implementing. Linear phases fight against how work actually happens.
+
+**OPSX approach:**
+- **Actions, not phases** — create, implement, update, archive — do any of them anytime
+- **Dependencies are enablers** — they show what's possible, not what's required next
+
+```
+  proposal ──→ specs ──→ design ──→ tasks ──→ implement
+```
+
+## Setup
+
+```bash
+# Make sure you have openspec installed — skills are automatically generated
+openspec init
+```
+
+This creates skills in `.claude/skills/` (or equivalent) that AI coding assistants auto-detect.
+
+During setup, you'll be prompted to create a **project config** (`openspec/config.yaml`). This is optional but recommended.
+
+## Project Configuration
+
+Project config lets you set defaults and inject project-specific context into all artifacts.
+
+### Creating Config
+
+Config is created during `openspec init`, or manually:
+
+```yaml
+# openspec/config.yaml
+schema: spec-driven
+
+context: |
+  Tech stack: TypeScript, React, Node.js
+  API conventions: RESTful, JSON responses
+  Testing: Vitest for unit tests, Playwright for e2e
+  Style: ESLint with Prettier, strict TypeScript
+
+rules:
+  proposal:
+    - Include rollback plan
+    - Identify affected teams
+  specs:
+    - Use Given/When/Then format for scenarios
+  design:
+    - Include sequence diagrams for complex flows
+```
+
+### Config Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `schema` | string | Default schema for new changes (e.g., `spec-driven`) |
+| `context` | string | Project context injected into all artifact instructions |
+| `rules` | object | Per-artifact rules, keyed by artifact ID |
+
+### How It Works
+
+**Schema precedence** (highest to lowest):
+1. CLI flag (`--schema <name>`)
+2. Change metadata (`.openspec.yaml` in change directory)
+3. Project config (`openspec/config.yaml`)
+4. Default (`spec-driven`)
+
+**Context injection:**
+- Context is prepended to every artifact's instructions
+- Wrapped in `<context>...</context>` tags
+- Helps AI understand your project's conventions
+
+**Rules injection:**
+- Rules are only injected for matching artifacts
+- Wrapped in `<rules>...</rules>` tags
+- Appear after context, before the template
+
+### Artifact IDs by Schema
+
+**spec-driven** (default):
+- `proposal` — Change proposal
+- `specs` — Specifications
+- `design` — Technical design
+- `tasks` — Implementation tasks
+
+### Config Validation
+
+- Unknown artifact IDs in `rules` generate warnings
+- Schema names are validated against available schemas
+- Context has a 50KB size limit
+- Invalid YAML is reported with line numbers
+
+### Troubleshooting
+
+**"Unknown artifact ID in rules: X"**
+- Check artifact IDs match your schema (see list above)
+- Run `openspec schemas --json` to see artifact IDs for each schema
+
+**Config not being applied:**
+- Ensure file is at `openspec/config.yaml` (not `.yml`)
+- Check YAML syntax with a validator
+- Config changes take effect immediately (no restart needed)
+
+**Context too large:**
+- Context is limited to 50KB
+- Summarize or link to external docs instead
+
+## Commands
+
+| Command | What it does |
+|---------|--------------|
+| `/opsx:explore` | Think through ideas, investigate problems, clarify requirements |
+| `/opsx:new` | Start a new change |
+| `/opsx:continue` | Create the next artifact (based on what's ready) |
+| `/opsx:ff` | Fast-forward — create all planning artifacts at once |
+| `/opsx:apply` | Implement tasks, updating artifacts as needed |
+| `/opsx:sync` | Sync delta specs to main (optional—archive prompts if needed) |
+| `/opsx:archive` | Archive when done |
+
+## Usage
+
+### Explore an idea
+```
+/opsx:explore
+```
+Think through ideas, investigate problems, compare options. No structure required - just a thinking partner. When insights crystallize, transition to `/opsx:new` or `/opsx:ff`.
+
+### Start a new change
+```
+/opsx:new
+```
+You'll be asked what you want to build and which workflow schema to use.
+
+### Create artifacts
+```
+/opsx:continue
+```
+Shows what's ready to create based on dependencies, then creates one artifact. Use repeatedly to build up your change incrementally.
+
+```
+/opsx:ff add-dark-mode
+```
+Creates all planning artifacts at once. Use when you have a clear picture of what you're building.
+
+### Implement (the fluid part)
+```
+/opsx:apply
+```
+Works through tasks, checking them off as you go. If you're juggling multiple changes, you can run `/opsx:apply <name>`; otherwise it should infer from the conversation and prompt you to choose if it can't tell.
+
+### Finish up
+```
+/opsx:archive   # Move to archive when done (prompts to sync specs if needed)
+```
+
+## When to Update vs. Start Fresh
+
+You can always edit your proposal or specs before implementation. But when does refining become "this is different work"?
+
+### What a Proposal Captures
+
+A proposal defines three things:
+1. **Intent** — What problem are you solving?
+2. **Scope** — What's in/out of bounds?
+3. **Approach** — How will you solve it?
+
+The question is: which changed, and by how much?
+
+### Update the Existing Change When:
+
+**Same intent, refined execution**
+- You discover edge cases you didn't consider
+- The approach needs tweaking but the goal is unchanged
+- Implementation reveals the design was slightly off
+
+**Scope narrows**
+- You realize full scope is too big, want to ship MVP first
+- "Add dark mode" → "Add dark mode toggle (system preference in v2)"
+
+**Learning-driven corrections**
+- Codebase isn't structured how you thought
+- A dependency doesn't work as expected
+- "Use CSS variables" → "Use Tailwind's dark: prefix instead"
+
+### Start a New Change When:
+
+**Intent fundamentally changed**
+- The problem itself is different now
+- "Add dark mode" → "Add comprehensive theme system with custom colors, fonts, spacing"
+
+**Scope exploded**
+- Change grew so much it's essentially different work
+- Original proposal would be unrecognizable after updates
+- "Fix login bug" → "Rewrite auth system"
+
+**Original is completable**
+- The original change can be marked "done"
+- New work stands alone, not a refinement
+- Complete "Add dark mode MVP" → Archive → New change "Enhance dark mode"
+

+       UPDATE            NEW  UPDATE       NEW  UPDATE          NEW
+```
+
+| Test | Update | New Change |
+|------|--------|------------|
+| **Identity** | "Same thing, refined" | "Different work" |
+| **Scope overlap** | >50% overlaps | <50% overlaps |
+| **Completion** | Can't be "done" without changes | Can finish original, new work stands alone |
+| **Story** | Update chain tells coherent story | Patches would confuse more than clarify |
+
+### The Principle
+
+> **Update preserves context. New change provides clarity.**
+>
+> Choose update when the history of your thinking is valuable.
+> Choose new when starting fresh would be clearer than patching.
+
+Think of it like git branches:
+- Keep committing while working on the same feature
+- Start a new branch when it's genuinely new work
+- Sometimes merge a partial feature and start fresh for phase 2
+
+## What's Different?
+
+| | Legacy (`/openspec:proposal`) | OPSX (`/opsx:*`) |
+|---|---|---|
+| **Structure** | One big proposal document | Discrete artifacts with dependencies |
+| **Workflow** | Linear phases: plan → implement → archive | Fluid actions — do anything anytime |
+| **Iteration** | Awkward to go back | Update artifacts as you learn |
+| **Customization** | Fixed structure | Schema-driven (define your own artifacts) |
+
+**The key insight:** work isn't linear. OPSX stops pretending it is.

+      │                └── Creates ONE artifact, shows what's unlocked
+      │
+      └── Scaffolds change, waits for direction
+```
+
+### Custom Schemas
+
+Create custom workflows using the schema management commands:
+
+```bash
+# Create a new schema from scratch (interactive)
+openspec schema init my-workflow
+
+# Or fork an existing schema as a starting point
+openspec schema fork spec-driven my-workflow
+
+# Validate your schema structure
+openspec schema validate my-workflow
+
+# See where a schema resolves from (useful for debugging)
+openspec schema which my-workflow
+```
+
+Schemas are stored in `openspec/schemas/` (project-local, version controlled) or `~/.local/share/openspec/schemas/` (user global).
+
+**Schema structure:**
+```
+openspec/schemas/research-first/
+├── schema.yaml
+└── templates/
+    ├── research.md
+    ├── proposal.md
+    └── tasks.md
+```
+
+**Example schema.yaml:**
+```yaml
+name: research-first
+artifacts:
+  - id: research        # Added before proposal
+    generates: research.md
+    requires: []
+
+  - id: proposal
+    generates: proposal.md
+    requires: [research]  # Now depends on research
+
+  - id: tasks
+    generates: tasks.md
+    requires: [proposal]
+```
+
+**Dependency Graph:**
+```
+   research ──► proposal ──► tasks
+```
+
+### Summary
+
+| Aspect | Legacy | OPSX |
+|--------|----------|------|
+| **Templates** | Hardcoded TypeScript | External YAML + Markdown |
+| **Dependencies** | None (all at once) | DAG with topological sort |
+| **State** | Phase-based mental model | Filesystem existence |
+| **Customization** | Edit source, rebuild | Create schema.yaml |
+| **Iteration** | Phase-locked | Fluid, edit anything |
+| **Editor Support** | 18+ configurator classes | Single skills directory |
+
+## Schemas
+
+Schemas define what artifacts exist and their dependencies. Currently available:
+
+- **spec-driven** (default): proposal → specs → design → tasks
+
+```bash
+# List available schemas
+openspec schemas
+
+# See all schemas with their resolution sources
+openspec schema which --all
+
+# Create a new schema interactively
+openspec schema init my-workflow
+
+# Fork an existing schema for customization
+openspec schema fork spec-driven my-workflow
+
+# Validate schema structure before use
+openspec schema validate my-workflow
+```
+
+## Tips
+
+- Use `/opsx:explore` to think through an idea before committing to a change
+- `/opsx:ff` when you know what you want, `/opsx:continue` when exploring
+- During `/opsx:apply`, if something's wrong — fix the artifact, then continue
+- Tasks track progress via checkboxes in `tasks.md`
+- Check status anytime: `openspec status --change "name"`

+# Supported Tools
+
+OpenSpec works with 20+ AI coding assistants. When you run `openspec init`, you'll be prompted to select which tools you use, and OpenSpec will configure the appropriate integrations.
+
+## How It Works
+
+For each tool you select, OpenSpec installs:
+
+1. **Skills** — Reusable instruction files that power the `/opsx:*` workflow commands
+2. **Commands** — Tool-specific slash command bindings
+
+## Tool Directory Reference
+
+| Tool | Skills Location | Commands Location |
+|------|-----------------|-------------------|
+| Amazon Q Developer | `.amazonq/skills/` | `.amazonq/prompts/` |
+| Antigravity | `.agent/skills/` | `.agent/workflows/` |
+| Auggie (Augment CLI) | `.augment/skills/` | `.augment/commands/` |
+| Claude Code | `.claude/skills/` | `.claude/commands/opsx/` |
+| Cline | `.cline/skills/` | `.clinerules/workflows/` |
+| CodeBuddy | `.codebuddy/skills/` | `.codebuddy/commands/opsx/` |
+| Codex | `.codex/skills/` | `~/.codex/prompts/`\* |
+| Continue | `.continue/skills/` | `.continue/prompts/` |
+| CoStrict | `.cospec/skills/` | `.cospec/openspec/commands/` |
+| Crush | `.crush/skills/` | `.crush/commands/opsx/` |
+| Cursor | `.cursor/skills/` | `.cursor/commands/` |
+| Factory Droid | `.factory/skills/` | `.factory/commands/` |
+| Gemini CLI | `.gemini/skills/` | `.gemini/commands/opsx/` |
+| GitHub Copilot | `.github/skills/` | `.github/prompts/`\*\* |
+| iFlow | `.iflow/skills/` | `.iflow/commands/` |
+| Kilo Code | `.kilocode/skills/` | `.kilocode/workflows/` |
+| Kiro | `.kiro/skills/` | `.kiro/prompts/` |
+| OpenCode | `.opencode/skills/` | `.opencode/command/` |
+| Pi | `.pi/skills/` | `.pi/prompts/` |
+| Qoder | `.qoder/skills/` | `.qoder/commands/opsx/` |
+| Qwen Code | `.qwen/skills/` | `.qwen/commands/` |
+| RooCode | `.roo/skills/` | `.roo/commands/` |
+| Trae | `.trae/skills/` | `.trae/skills/` (via `/openspec-*`) |
+| Windsurf | `.windsurf/skills/` | `.windsurf/workflows/` |
+
+\* Codex commands are installed to the global home directory (`~/.codex/prompts/` or `$CODEX_HOME/prompts/`), not the project directory.
+
+\*\* GitHub Copilot's `.github/prompts/*.prompt.md` files are recognized as custom slash commands in **IDE extensions only** (VS Code, JetBrains, Visual Studio). GitHub Copilot CLI does not currently support custom prompts from this directory — see [github/copilot-cli#618](https://github.com/github/copilot-cli/issues/618). If you use Copilot CLI, you may need to manually set up [custom agents](https://docs.github.com/en/copilot/how-tos/use-copilot-agents/coding-agent/create-custom-agents) in `.github/agents/` as a workaround.
+
+## Non-Interactive Setup
+
+For CI/CD or scripted setup, use the `--tools` flag:
+
+```bash
+# Configure specific tools
+openspec init --tools claude,cursor
+
+# Configure all supported tools
+openspec init --tools all
+
+# Skip tool configuration
+openspec init --tools none
+```
+
+**Available tool IDs:** `amazon-q`, `antigravity`, `auggie`, `claude`, `cline`, `codebuddy`, `codex`, `continue`, `costrict`, `crush`, `cursor`, `factory`, `gemini`, `github-copilot`, `iflow`, `kilocode`, `kiro`, `opencode`, `pi`, `qoder`, `qwen`, `roocode`, `trae`, `windsurf`
+
+## What Gets Installed
+
+For each tool, OpenSpec generates 10 skill files that power the OPSX workflow:
+
+| Skill | Purpose |
+|-------|---------|
+| `openspec-explore` | Thinking partner for exploring ideas |
+| `openspec-new-change` | Start a new change |
+| `openspec-continue-change` | Create the next artifact |
+| `openspec-ff-change` | Fast-forward through all planning artifacts |
+| `openspec-apply-change` | Implement tasks |
+| `openspec-verify-change` | Verify implementation completeness |
+| `openspec-sync-specs` | Sync delta specs to main (optional—archive prompts if needed) |
+| `openspec-archive-change` | Archive a completed change |
+| `openspec-bulk-archive-change` | Archive multiple changes at once |
+| `openspec-onboard` | Guided onboarding through a complete workflow cycle |
+
+These skills are invoked via slash commands like `/opsx:new`, `/opsx:apply`, etc. See [Commands](commands.md) for the full list.

+# Workflows
+
+This guide covers common workflow patterns for OpenSpec and when to use each one. For basic setup, see [Getting Started](getting-started.md). For command reference, see [Commands](commands.md).
+
+## Philosophy: Actions, Not Phases
+
+Traditional workflows force you through phases: planning, then implementation, then done. But real work doesn't fit neatly into boxes.
+
+OPSX takes a different approach:
+
+```text
+Traditional (phase-locked):
+
+  PLANNING ────────► IMPLEMENTING ────────► DONE
+      │                    │
+      │   "Can't go back"  │
+      └────────────────────┘
+
+OPSX (fluid actions):
+
+  proposal ──► specs ──► design ──► tasks ──► implement
+```
+
+**Key principles:**
+
+- **Actions, not phases** - Commands are things you can do, not stages you're stuck in
+- **Dependencies are enablers** - They show what's possible, not what's required next
+
+> **Customization:** OPSX workflows are driven by schemas that define artifact sequences. See [Customization](customization.md) for details on creating custom schemas.
+
+## Workflow Patterns
+
+### Quick Feature
+
+When you know what you want to build and just need to execute:
+
+```text
+/opsx:new ──► /opsx:ff ──► /opsx:apply ──► /opsx:verify ──► /opsx:archive
+```
+
+**Example conversation:**
+
+```text
+You: /opsx:new add-logout-button
+
+AI:  Created openspec/changes/add-logout-button/
+     Ready to create: proposal
+
+You: /opsx:ff
+
+AI:  Creating all planning artifacts...
+     ✓ proposal.md
+     ✓ specs/
+     ✓ design.md
+     ✓ tasks.md
+     Ready for implementation!
+
+You: /opsx:apply
+
+AI:  Working through tasks...
+     ✓ Added logout button to header
+     ✓ Implemented session clearing
+     ✓ Added confirmation dialog
+     All tasks complete!
+
+You: /opsx:archive
+
+AI:  ✓ Merged specs
+     ✓ Archived change
+```
+
+**Best for:** Small to medium features, bug fixes, straightforward changes.
+
+### Exploratory
+
+When requirements are unclear or you need to investigate first:
+
+```text
+/opsx:explore ──► /opsx:new ──► /opsx:continue ──► ... ──► /opsx:apply
+```
+
+**Example conversation:**
+
+```text
+You: /opsx:explore
+
+AI:  What would you like to explore?
+
+You: I want to improve page load performance but I'm not sure
+     where the bottlenecks are.
+
+AI:  Let me help investigate...
+     [Analyzes bundle sizes, identifies slow queries, reviews
+     component render patterns]
+
+     I found three main bottlenecks:
+     1. Large unoptimized images
+     2. Synchronous data fetching in ProductList
+     3. Re-renders from context changes
+
+     Which would you like to address first?
+
+You: Let's tackle the data fetching issue.
+
+You: /opsx:new optimize-product-list-fetching
+
+AI:  Created change. Ready to create: proposal
+
+You: /opsx:continue
+
+AI:  Creating proposal based on our exploration...
+     [Writes proposal incorporating investigation insights]
+
+     Ready to create: specs, design
+     Which would you like next?
+
+You: /opsx:continue
+
+AI:  Creating specs...
+```
+
+**Best for:** Performance optimization, debugging, architectural decisions, unclear requirements.
+
+### Parallel Changes
+
+Work on multiple changes at once:
+
+```text
+Change A: /opsx:new ──► /opsx:ff ──► /opsx:apply (in progress)
+                                         │
+                                    context switch
+                                         │
+Change B: /opsx:new ──► /opsx:ff ──────► /opsx:apply
+```
+
+**Example conversation:**
+
+```text
+You: I'm working on add-dark-mode but got pulled into a bug fix
+
+You: /opsx:new fix-login-redirect
+
+AI:  Created openspec/changes/fix-login-redirect/
+
+You: /opsx:ff
+
+AI:  ✓ Created planning artifacts
+
+You: /opsx:apply
+
+AI:  Working on fix-login-redirect...
+     [Implements the fix]
+     All tasks complete!
+
+You: /opsx:archive
+
+AI:  ✓ Archived fix-login-redirect
+
+You: Let's get back to dark mode
+
+You: /opsx:apply add-dark-mode
+
+AI:  Resuming add-dark-mode...
+     Picking up at task 2.3: Update Header...
+```
+
+**Best for:** Parallel work streams, urgent interrupts, team collaboration.
+
+When you have multiple completed changes, use `/opsx:bulk-archive`:
+
+```text
+You: /opsx:bulk-archive
+
+AI:  Found 3 completed changes:
+     - add-dark-mode (all tasks done)
+     - fix-login-redirect (all tasks done)
+     - update-footer (all tasks done)
+
+     Checking for spec conflicts...
+     ⚠ add-dark-mode and update-footer both touch specs/ui/
+
+     Inspecting codebase to resolve...
+     Both changes are implemented. Will apply in chronological order.
+
+     Archive all 3 changes?
+
+You: Yes
+
+AI:  ✓ Archived add-dark-mode
+     ✓ Archived fix-login-redirect
+     ✓ Archived update-footer
+     Specs merged in order: add-dark-mode → update-footer
+```
+
+Bulk archive detects when multiple changes touch the same specs and resolves conflicts by checking what's actually implemented.
+
+### Completing a Change
+
+The recommended completion flow:
+
+```text
+/opsx:apply ──► /opsx:verify ──► /opsx:archive
+                    │                 │
+              validates          prompts to sync
+              implementation     if needed
+```
+
+#### Verify: Check Your Work
+
+`/opsx:verify` validates implementation against your artifacts across three dimensions:
+
+```text
+You: /opsx:verify
+
+AI:  Verifying add-auth...
+
+     COMPLETENESS
+     ✓ All 12 tasks in tasks.md are checked
+     ✓ All requirements in specs have corresponding code
+     ⚠ Scenario "Session timeout after inactivity" not tested
+
+     CORRECTNESS
+     ✓ Implementation matches spec intent
+     ✓ Edge cases from scenarios are handled
+     ✓ Error states match spec definitions
+
+     COHERENCE
+     ✓ Design decisions reflected in code structure
+     ✓ Naming conventions consistent with design.md
+     ⚠ Design mentions "event-driven" but implementation uses polling
+
+     SUMMARY
+     ─────────────────────────────
+     Critical issues: 0
+     Warnings: 2
+     Ready to archive: Yes (with warnings)
+
+     Recommendations:
+     1. Add test for session timeout scenario
+     2. Consider refactoring to event-driven as designed, or update design.md
+```
+
+**What verify checks:**
+
+| Dimension | What it validates |
+|-----------|------------------|
+| Completeness | All tasks done, all requirements implemented, scenarios covered |
+| Correctness | Implementation matches spec intent, edge cases handled |
+| Coherence | Design decisions reflected in code, patterns consistent |
+
+Verify won't block archive, but it surfaces issues you might want to address first.
+
+#### Archive: Finalize the Change
+
+`/opsx:archive` completes the change and moves it to the archive:
+
+```text
+You: /opsx:archive
+
+AI:  Archiving add-auth...
+
+     Artifact status:
+     ✓ proposal.md exists
+     ✓ specs/ exists
+     ✓ design.md exists
+     ✓ tasks.md exists (12/12 tasks complete)
+
+     Delta specs: Not yet synced to main
+     → Would you like to sync now?
+
+You: Yes
+
+AI:  ✓ Synced specs to openspec/specs/auth/spec.md
+     ✓ Moved to openspec/changes/archive/2025-01-24-add-auth/
+
+     Change archived successfully.
+```
+
+Archive will prompt if specs aren't synced. It won't block on incomplete tasks, but it will warn you.
+
+## When to Use What
+
+### `/opsx:ff` vs `/opsx:continue`
+
+| Situation | Use |
+|-----------|-----|
+| Clear requirements, ready to build | `/opsx:ff` |
+| Exploring, want to review each step | `/opsx:continue` |
+| Want to iterate on proposal before specs | `/opsx:continue` |
+| Time pressure, need to move fast | `/opsx:ff` |
+| Complex change, want control | `/opsx:continue` |
+
+**Rule of thumb:** If you can describe the full scope upfront, use `/opsx:ff`. If you're figuring it out as you go, use `/opsx:continue`.
+
+### When to Update vs Start Fresh
+
+A common question: when is updating an existing change okay, and when should you start a new one?
+
+**Update the existing change when:**
+
+- Same intent, refined execution
+- Scope narrows (MVP first, rest later)
+- Learning-driven corrections (codebase isn't what you expected)
+- Design tweaks based on implementation discoveries
+
+**Start a new change when:**
+
+- Intent fundamentally changed
+- Scope exploded to different work entirely
+- Original change can be marked "done" standalone
+- Patches would confuse more than clarify
+
+```text
+                     ┌─────────────────────────────────────┐
+                     │     Is this the same work?          │
+                     └──────────────┬──────────────────────┘
+                                    │
+                 ┌──────────────────┼──────────────────┐
+                 │                  │                  │
+                 ▼                  ▼                  ▼
+          Same intent?      >50% overlap?      Can original
+          Same problem?     Same scope?        be "done" without
+                 │                  │          these changes?
+                 │                  │                  │
+       ┌────────┴────────┐  ┌──────┴──────┐   ┌───────┴───────┐
+       │                 │  │             │   │               │
+      YES               NO YES           NO  NO              YES
+       │                 │  │             │   │               │
+       ▼                 ▼  ▼             ▼   ▼               ▼
+    UPDATE            NEW  UPDATE       NEW  UPDATE          NEW
+```
+
+**Example: "Add dark mode"**
+
+- "Need to also support custom themes" → New change (scope exploded)
+- "System preference detection is harder than expected" → Update (same intent)
+- "Let's ship toggle first, add preferences later" → Update then archive, then new change
+
+## Best Practices
+
+### Keep Changes Focused
+
+One logical unit of work per change. If you're doing "add feature X and also refactor Y", consider two separate changes.
+
+**Why it matters:**
+- Easier to review and understand
+- Cleaner archive history
+- Can ship independently
+- Simpler rollback if needed
+
+### Use `/opsx:explore` for Unclear Requirements
+
+Before committing to a change, explore the problem space:
+
+```text
+You: /opsx:explore
+
+AI:  What would you like to explore?
+
+You: How should we handle rate limiting for our API?
+
+AI:  Let me investigate your current setup and options...
+     [Researches codebase, considers patterns]
+
+     I see three approaches we could take:
+     1. Middleware-based (simple, per-endpoint)
+     2. Redis-backed (scalable, shared state)
+     3. Token bucket per user (fair, complex)
+
+     Your current stack suggests #1 or #2. What's your scale?
+```
+
+Exploration clarifies thinking before you create artifacts.
+
+### Verify Before Archiving
+
+Use `/opsx:verify` to check implementation matches artifacts:
+
+```text
+You: /opsx:verify
+
+AI:  Verifying add-dark-mode...
+
+     ✓ All tasks in tasks.md are checked
+     ✓ Requirements in specs have corresponding code
+     ✓ Design decisions are reflected in implementation
+
+     Ready to archive!
+```
+
+Catches mismatches before you close out the change.
+
+### Name Changes Clearly
+
+Good names make `openspec list` useful:
+
+```text
+Good:                          Avoid:
+add-dark-mode                  feature-1
+fix-login-redirect             update
+optimize-product-query         changes
+implement-2fa                  wip
+```

-# OpenSpec Instructions
-
-Instructions for AI coding assistants using OpenSpec for spec-driven development.
-
-## TL;DR Quick Checklist
-
-- Search existing work: `openspec spec list --long`, `openspec list` (use `rg` only for full-text search)
-- Decide scope: new capability vs modify existing capability
-- Pick a unique `change-id`: kebab-case, verb-led (`add-`, `update-`, `remove-`, `refactor-`)
-- Scaffold: `proposal.md`, `tasks.md`, `design.md` (only if needed), and delta specs per affected capability
-- Write deltas: use `## ADDED|MODIFIED|REMOVED|RENAMED Requirements`; include at least one `#### Scenario:` per requirement
-- Validate: `openspec validate [change-id] --strict` and fix issues
-- Request approval: Do not start implementation until proposal is approved
-
-## Three-Stage Workflow
-
-### Stage 1: Creating Changes
-Create proposal when you need to:
-- Add features or functionality
-- Make breaking changes (API, schema)
-- Change architecture or patterns  
-- Optimize performance (changes behavior)
-- Update security patterns
-
-Triggers (examples):
-- "Help me create a change proposal"
-- "Help me plan a change"
-- "Help me create a proposal"
-- "I want to create a spec proposal"
-- "I want to create a spec"
-
-Loose matching guidance:
-- Contains one of: `proposal`, `change`, `spec`
-- With one of: `create`, `plan`, `make`, `start`, `help`
-
-Skip proposal for:
-- Bug fixes (restore intended behavior)
-- Typos, formatting, comments
-- Dependency updates (non-breaking)
-- Configuration changes
-- Tests for existing behavior
-
-**Workflow**
-1. Review `openspec/project.md`, `openspec list`, and `openspec list --specs` to understand current context.
-2. Choose a unique verb-led `change-id` and scaffold `proposal.md`, `tasks.md`, optional `design.md`, and spec deltas under `openspec/changes/<id>/`.
-3. Draft spec deltas using `## ADDED|MODIFIED|REMOVED Requirements` with at least one `#### Scenario:` per requirement.
-4. Run `openspec validate <id> --strict` and resolve any issues before sharing the proposal.
-
-### Stage 2: Implementing Changes
-Track these steps as TODOs and complete them one by one.
-1. **Read proposal.md** - Understand what's being built
-2. **Read design.md** (if exists) - Review technical decisions
-3. **Read tasks.md** - Get implementation checklist
-4. **Implement tasks sequentially** - Complete in order
-5. **Confirm completion** - Ensure every item in `tasks.md` is finished before updating statuses
-6. **Update checklist** - After all work is done, set every task to `- [x]` so the list reflects reality
-7. **Approval gate** - Do not start implementation until the proposal is reviewed and approved
-
-### Stage 3: Archiving Changes
-After deployment, create separate PR to:
-- Move `changes/[name]/` → `changes/archive/YYYY-MM-DD-[name]/`
-- Update `specs/` if capabilities changed
-- Use `openspec archive <change-id> --skip-specs --yes` for tooling-only changes (always pass the change ID explicitly)
-- Run `openspec validate --strict` to confirm the archived change passes checks
-
-## Before Any Task
-
-**Context Checklist:**
-- [ ] Read relevant specs in `specs/[capability]/spec.md`
-- [ ] Check pending changes in `changes/` for conflicts
-- [ ] Read `openspec/project.md` for conventions
-- [ ] Run `openspec list` to see active changes
-- [ ] Run `openspec list --specs` to see existing capabilities
-
-**Before Creating Specs:**
-- Always check if capability already exists
-- Prefer modifying existing specs over creating duplicates
-- Use `openspec show [spec]` to review current state
-- If request is ambiguous, ask 1–2 clarifying questions before scaffolding
-
-### Search Guidance
-- Enumerate specs: `openspec spec list --long` (or `--json` for scripts)
-- Enumerate changes: `openspec list` (or `openspec change list --json` - deprecated but available)
-- Show details:
-  - Spec: `openspec show <spec-id> --type spec` (use `--json` for filters)
-  - Change: `openspec show <change-id> --json --deltas-only`
-- Full-text search (use ripgrep): `rg -n "Requirement:|Scenario:" openspec/specs`
-
-## Quick Start
-
-### CLI Commands
-
-```bash
-# Essential commands
-openspec list                  # List active changes
-openspec list --specs          # List specifications
-openspec show [item]           # Display change or spec
-openspec validate [item]       # Validate changes or specs
-openspec archive <change-id> [--yes|-y]   # Archive after deployment (add --yes for non-interactive runs)
-
-# Project management
-openspec init [path]           # Initialize OpenSpec
-openspec update [path]         # Update instruction files
-
-# Interactive mode
-openspec show                  # Prompts for selection
-openspec validate              # Bulk validation mode
-
-# Debugging
-openspec show [change] --json --deltas-only
-openspec validate [change] --strict
-```
-
-### Command Flags
-
-- `--json` - Machine-readable output
-- `--type change|spec` - Disambiguate items
-- `--strict` - Comprehensive validation
-- `--no-interactive` - Disable prompts
-- `--skip-specs` - Archive without spec updates
-- `--yes`/`-y` - Skip confirmation prompts (non-interactive archive)
-

-
-## Creating Change Proposals
-
-### Decision Tree
-
-```
-New request?
-├─ Bug fix restoring spec behavior? → Fix directly
-├─ Typo/format/comment? → Fix directly  
-├─ New feature/capability? → Create proposal
-├─ Breaking change? → Create proposal
-├─ Architecture change? → Create proposal
-└─ Unclear? → Create proposal (safer)
-```
-
-### Proposal Structure
-
-1. **Create directory:** `changes/[change-id]/` (kebab-case, verb-led, unique)
-
-2. **Write proposal.md:**
-```markdown
-## Why
-[1-2 sentences on problem/opportunity]
-
-## What Changes
-- [Bullet list of changes]
-- [Mark breaking changes with **BREAKING**]
-
-## Impact
-- Affected specs: [list capabilities]
-- Affected code: [key files/systems]
-```
-
-3. **Create spec deltas:** `specs/[capability]/spec.md`
-```markdown
-## ADDED Requirements
-### Requirement: New Feature
-The system SHALL provide...
-
-#### Scenario: Success case
-- **WHEN** user performs action
-- **THEN** expected result
-
-## MODIFIED Requirements
-### Requirement: Existing Feature
-[Complete modified requirement]
-
-## REMOVED Requirements
-### Requirement: Old Feature
-**Reason**: [Why removing]
-**Migration**: [How to handle]
-```
-If multiple capabilities are affected, create multiple delta files under `changes/[change-id]/specs/<capability>/spec.md`—one per capability.
-
-4. **Create tasks.md:**
-```markdown
-## 1. Implementation
-- [ ] 1.1 Create database schema
-- [ ] 1.2 Implement API endpoint
-- [ ] 1.3 Add frontend component
-- [ ] 1.4 Write tests
-```
-
-5. **Create design.md when needed:**
-Create `design.md` if any of the following apply; otherwise omit it:
-- Cross-cutting change (multiple services/modules) or a new architectural pattern
-- New external dependency or significant data model changes
-- Security, performance, or migration complexity
-- Ambiguity that benefits from technical decisions before coding
-
-Minimal `design.md` skeleton:
-```markdown
-## Context
-[Background, constraints, stakeholders]
-
-## Goals / Non-Goals
-- Goals: [...]
-- Non-Goals: [...]
-
-## Decisions
-- Decision: [What and why]
-- Alternatives considered: [Options + rationale]
-
-## Risks / Trade-offs
-- [Risk] → Mitigation
-
-## Migration Plan
-[Steps, rollback]
-
-## Open Questions
-- [...]
-```
-
-## Spec File Format
-
-### Critical: Scenario Formatting
-
-**CORRECT** (use #### headers):
-```markdown
-#### Scenario: User login success
-- **WHEN** valid credentials provided
-- **THEN** return JWT token
-```
-
-**WRONG** (don't use bullets or bold):
-```markdown
-- **Scenario: User login**  ❌
-**Scenario**: User login     ❌
-### Scenario: User login      ❌
-```
-
-Every requirement MUST have at least one scenario.
-
-### Requirement Wording
-- Use SHALL/MUST for normative requirements (avoid should/may unless intentionally non-normative)
-
-### Delta Operations
-
-- `## ADDED Requirements` - New capabilities
-- `## MODIFIED Requirements` - Changed behavior
-- `## REMOVED Requirements` - Deprecated features
-- `## RENAMED Requirements` - Name changes
-
-Headers matched with `trim(header)` - whitespace ignored.
-
-#### When to use ADDED vs MODIFIED
-- ADDED: Introduces a new capability or sub-capability that can stand alone as a requirement. Prefer ADDED when the change is orthogonal (e.g., adding "Slash Command Configuration") rather than altering the semantics of an existing requirement.
-- MODIFIED: Changes the behavior, scope, or acceptance criteria of an existing requirement. Always paste the full, updated requirement content (header + all scenarios). The archiver will replace the entire requirement with what you provide here; partial deltas will drop previous details.
-- RENAMED: Use when only the name changes. If you also change behavior, use RENAMED (name) plus MODIFIED (content) referencing the new name.
-
-Common pitfall: Using MODIFIED to add a new concern without including the previous text. This causes loss of detail at archive time. If you aren’t explicitly changing the existing requirement, add a new requirement under ADDED instead.
-
-Authoring a MODIFIED requirement correctly:
-1) Locate the existing requirement in `openspec/specs/<capability>/spec.md`.
-2) Copy the entire requirement block (from `### Requirement: ...` through its scenarios).
-3) Paste it under `## MODIFIED Requirements` and edit to reflect the new behavior.
-4) Ensure the header text matches exactly (whitespace-insensitive) and keep at least one `#### Scenario:`.
-
-Example for RENAMED:
-```markdown
-## RENAMED Requirements
-- FROM: `### Requirement: Login`
-- TO: `### Requirement: User Authentication`
-```
-
-## Troubleshooting
-
-### Common Errors
-
-**"Change must have at least one delta"**
-- Check `changes/[name]/specs/` exists with .md files
-- Verify files have operation prefixes (## ADDED Requirements)
-
-**"Requirement must have at least one scenario"**
-- Check scenarios use `#### Scenario:` format (4 hashtags)
-- Don't use bullet points or bold for scenario headers
-
-**Silent scenario parsing failures**
-- Exact format required: `#### Scenario: Name`
-- Debug with: `openspec show [change] --json --deltas-only`
-
-### Validation Tips
-
-```bash
-# Always use strict mode for comprehensive checks
-openspec validate [change] --strict
-
-# Debug delta parsing
-openspec show [change] --json | jq '.deltas'
-
-# Check specific requirement
-openspec show [spec] --json -r 1
-```
-
-## Happy Path Script
-
-```bash
-# 1) Explore current state
-openspec spec list --long
-openspec list
-# Optional full-text search:
-# rg -n "Requirement:|Scenario:" openspec/specs
-# rg -n "^#|Requirement:" openspec/changes
-
-# 2) Choose change id and scaffold
-CHANGE=add-two-factor-auth
-mkdir -p openspec/changes/$CHANGE/{specs/auth}
-printf "## Why\n...\n\n## What Changes\n- ...\n\n## Impact\n- ...\n" > openspec/changes/$CHANGE/proposal.md
-printf "## 1. Implementation\n- [ ] 1.1 ...\n" > openspec/changes/$CHANGE/tasks.md
-
-# 3) Add deltas (example)
-cat > openspec/changes/$CHANGE/specs/auth/spec.md << 'EOF'
-## ADDED Requirements
-### Requirement: Two-Factor Authentication
-Users MUST provide a second factor during login.
-
-#### Scenario: OTP required
-- **WHEN** valid credentials are provided
-- **THEN** an OTP challenge is required
-EOF
-
-# 4) Validate
-openspec validate $CHANGE --strict
-```
-

-```
-

-## ADDED Requirements

-```
-
-## Best Practices
-
-### Simplicity First
-- Default to <100 lines of new code
-- Single-file implementations until proven insufficient
-- Avoid frameworks without clear justification
-- Choose boring, proven patterns
-
-### Complexity Triggers
-Only add complexity with:
-- Performance data showing current solution too slow
-- Concrete scale requirements (>1000 users, >100MB data)
-- Multiple proven use cases requiring abstraction
-
-### Clear References
-- Use `file.ts:42` format for code locations
-- Reference specs as `specs/auth/spec.md`
-- Link related changes and PRs
-
-### Capability Naming
-- Use verb-noun: `user-auth`, `payment-capture`
-- Single purpose per capability
-- 10-minute understandability rule
-- Split if description needs "AND"
-
-### Change ID Naming
-- Use kebab-case, short and descriptive: `add-two-factor-auth`
-- Prefer verb-led prefixes: `add-`, `update-`, `remove-`, `refactor-`
-- Ensure uniqueness; if taken, append `-2`, `-3`, etc.

-## Tool Selection Guide
-
-| Task | Tool | Why |
-|------|------|-----|
-| Find files by pattern | Glob | Fast pattern matching |
-| Search code content | Grep | Optimized regex search |
-| Read specific files | Read | Direct file access |
-| Explore unknown scope | Task | Multi-step investigation |
-
-## Error Recovery
-
-### Change Conflicts
-1. Run `openspec list` to see active changes
-2. Check for overlapping specs
-3. Coordinate with change owners
-4. Consider combining proposals
-
-### Validation Failures
-1. Run with `--strict` flag
-2. Check JSON output for details
-3. Verify spec file format
-4. Ensure scenarios properly formatted
-
-### Missing Context
-1. Read project.md first
-2. Check related specs
-3. Review recent archives
-4. Ask for clarification
-
-## Quick Reference
-
-### Stage Indicators
-- `changes/` - Proposed, not yet built
-- `specs/` - Built and deployed
-- `archive/` - Completed changes
-
-### File Purposes
-- `proposal.md` - Why and what
-- `tasks.md` - Implementation steps
-- `design.md` - Technical decisions
-- `spec.md` - Requirements and behavior
-
-### CLI Essentials
-```bash
-openspec list              # What's in progress?
-openspec show [item]       # View details
-openspec validate --strict # Is it correct?
-openspec archive <change-id> [--yes|-y]  # Mark complete (add --yes for automation)
-```

+# Add Artifact Regeneration Support
+
+## Problem
+
+Currently, there is **no way to regenerate artifacts** in the OPSX workflow:
+
+- `/opsx:apply` just reads whatever's on disk
+- `/opsx:continue` only creates the NEXT artifact - won't touch existing ones
+
+If you edit `design.md` after `tasks.md` exists, your only options are:
+1. Delete tasks.md manually, then run `/opsx:continue`
+2. Edit tasks.md manually
+
+The documentation claims you can "update artifacts mid-flight and continue" but there's no mechanism that actually supports this.
+
+## Proposed Solution
+
+Two parts:
+
+### Part 1: Staleness Detection
+Add artifact staleness detection to `/opsx:apply`:
+
+1. **Track modification times**: When generating an artifact, record the mtime of its dependencies
+2. **Detect staleness**: When `/opsx:apply` runs, check if upstream artifacts (design.md, specs) have been modified since tasks.md was generated
+3. **Prompt user**: If stale, ask: "Design was modified after tasks were generated. Would you like to regenerate tasks with `/opsx:continue`?"
+
+## User Experience
+
+### Vision: Seamless Mid-Flight Correction
+
+This is the workflow we want to enable (currently documented but not supported):
+
+```
+You: /opsx:apply
+
+AI:  Working through tasks...
+     ✓ Task 1.1: Created caching layer
+     ✓ Task 1.2: Added cache invalidation
+
+     Working on 1.3: Implement TTL...
+     I noticed the design assumes Redis, but your project uses
+     in-memory caching. Should I update the design?
+
+You: Yes, update it to use the existing cache module.
+
+AI:  Updated design.md to use CacheManager from src/cache/
+     Updated tasks.md with revised implementation steps
+     Continuing implementation...
+     ✓ Task 1.3: Implemented TTL using CacheManager
+     ...
+```
+
+**No restart needed.** Just update the artifact and continue.
+
+### Staleness Warning UX
+
+When user manually edits an upstream artifact:
+
+```

+
+### Part 2: Regeneration Capability
+
+Add a way to regenerate specific artifacts:
+
+```bash
+# Option A: Flag on continue
+/opsx:continue --regenerate tasks
+
+# Option B: Separate command
+/opsx:regenerate tasks
+
+# Option C: Interactive prompt when staleness detected
+/opsx:apply
+# "Design changed. Regenerate tasks? [y/N]"
+```
+
+## Technical Approach
+
+### Option A: Metadata File
+Store `.openspec-meta.json` in change directory:
+```json
+{
+  "tasks.md": {
+    "generated_at": "2025-01-24T10:00:00Z",
+    "dependencies": {
+      "design.md": "2025-01-24T09:55:00Z",
+      "specs/feature/spec.md": "2025-01-24T09:50:00Z"
+    }
+  }
+}
+```
+
+### Option B: Frontmatter
+Add YAML frontmatter to generated artifacts:
+```markdown
+---
+generated_at: 2025-01-24T10:00:00Z
+depends_on:
+  - design.md@2025-01-24T09:55:00Z
+---
+# Tasks
+...
+```
+
+### Option C: Git-based
+Use git to detect if upstream files changed since downstream was last modified. No extra metadata needed but requires git.
+
+## Non-Goals
+
+- Automatic regeneration (user should always choose)
+- Blocking apply entirely (just warn)
+- Tracking code file changes (only artifact dependencies)
+
+## Dependencies
+
+- Should be implemented after `fix-midflight-update-docs` so docs are accurate first
+- Could be combined with that change if desired
+
+## Success Criteria
+
+- User is warned when applying with stale artifacts
+- Clear path to regenerate if needed
+- No false positives (only warn when genuinely stale)
+- Documentation claims become actually true

+## Why
+
+Parallel changes often touch the same capabilities and `cli-init`/`cli-update` behavior, but today there is no machine-readable way to express sequencing, dependencies, or expected merge order.
+
+This creates three recurring problems:
+
+- teams cannot tell which change should land first
+- large changes are hard to split into safe mergeable slices
+- parallel work can accidentally reintroduce assumptions already removed by another change
+
+We need lightweight planning metadata and CLI guidance so contributors can safely stack plans on top of each other.
+
+## What Changes
+
+### 1. Add lightweight stack metadata for changes
+
+Extend change metadata to support sequencing and decomposition context, for example:
+
+- `dependsOn`: changes that must land first
+- `provides`: capability markers exposed by this change
+- `requires`: capability markers needed by this change
+- `touches`: capability/spec areas likely affected (advisory only; warning signal, not a hard dependency)
+- `parent`: optional parent change for split work
+
+Metadata is optional and backward compatible for existing changes.
+
+Ordering semantics:
+
+- `dependsOn` is the source of truth for execution/archive ordering
+- `provides`/`requires` are capability contracts for validation and planning visibility
+- `provides`/`requires` do not create implicit dependency edges; authors must still declare required ordering via `dependsOn`
+
+### 2. Add stack-aware validation
+
+Enhance change validation to detect planning issues early:
+
+- missing dependencies
+- dependency cycles
+- archive ordering violations (for example, attempting to archive a change before all `dependsOn` predecessors are archived)
+- unmatched capability markers (for example, `requires` marker with no provider in active history emits non-blocking warning)
+- overlap warnings when active changes touch the same capability
+
+Validation should fail only for deterministic blockers (for example cycles or missing required dependencies), and keep overlap checks as actionable warnings.
+
+### 3. Add sequencing visibility commands
+
+Add lightweight CLI support to inspect and execute plan order:
+
+- `openspec change graph` to show dependency DAG/order
+- `openspec change graph` validates for cycles first; when cycles are present it fails with the same deterministic cycle error as stack-aware validation
+- `openspec change next` to suggest unblocked changes ready to implement/archive
+
+### 4. Add split scaffolding for large changes
+
+Add helper workflow to decompose large proposals into stackable slices:
+
+- `openspec change split <change-id>` scaffolds child changes with `parent` + `dependsOn`
+- generates minimal proposal/tasks stubs for each child slice
+- converts the source change into a parent planning container (no duplicate child implementation tasks)
+- re-running split for an already-split source change returns a deterministic actionable error unless `--overwrite` (alias `--force`) is passed
+- `--overwrite` / `--force` fully regenerates managed child scaffold stubs and metadata links for the split, replacing prior scaffold content
+
+### 5. Document stack-first workflow
+
+Update docs to describe:
+
+- how to model dependencies and parent/child slices
+- when to split a large change
+- how to use graph/next validation signals during parallel development
+- migration guidance for `openspec/changes/IMPLEMENTATION_ORDER.md`:
+  - machine-readable change metadata becomes the normative dependency source
+  - `IMPLEMENTATION_ORDER.md` remains optional narrative context during transition
+
+## Capabilities
+
+### New Capabilities
+
+- `change-stacking-workflow`: Dependency-aware sequencing and split scaffolding for change planning
+
+### Modified Capabilities
+
+- `cli-change`: Adds graph/next/split planning commands and stack-aware validation messaging
+- `change-creation`: Supports parent/dependency metadata when creating or splitting changes
+- `openspec-conventions`: Defines optional stack metadata conventions for change proposals
+
+## Impact
+
+- `src/core/project-config.ts` and related parsing/validation utilities for change metadata loading
+- `src/core/config-schema.ts` (or dedicated change schema) for stack metadata validation
+- `src/commands/change.ts` and/or `src/core/list.ts` for graph/next/split command behavior
+- `src/core/validation/*` for dependency cycle and overlap checks
+- `docs/cli.md`, `docs/concepts.md`, and contributor guidance for stack-aware workflows
+- tests for metadata parsing, graph ordering, next-item suggestions, and split scaffolding

+## Context
+
+OpenSpec today assumes project-local installation for most generated artifacts, with Codex command prompts as the main global exception. This mixed model works, but it is implicit and not user-configurable.
+
+The requested change is to support user-selectable install scope (`global` or `project`) for tool skills/commands, defaulting to `global` for new configurations while preserving legacy project-local behavior until explicit migration.
+
+## Goals / Non-Goals
+
+**Goals:**
+
+- Provide a single scope preference that users can set globally and override per run
+- Default new users to `global` scope
+- Make install path resolution deterministic and explicit across tools/surfaces
+- Preserve current behavior for users with older config files that do not yet define `installScope`
+- Avoid silent partial installs; surface effective scope decisions in output
+
+**Non-Goals:**
+
+- Implementing project-local config file support for global settings
+- Defining global install paths for tools where upstream location conventions are unknown
+- Changing workflow/profile semantics (`core`, `custom`, `delivery`) in this change
+
+## Decisions
+
+### 1. Scope model in global config
+
+Add install scope preference to global config:
+
+```ts
+type InstallScope = 'global' | 'project';
+
+interface GlobalConfig {
+  // existing fields...
+  installScope?: InstallScope;
+}
+```
+
+Defaults:
+
+- New configs SHOULD write `installScope: global` explicitly.
+- Existing configs without this field continue to load safely through schema evolution and SHALL resolve effective default as `project` until users explicitly set `installScope`.
+
+### 2. Explicit tool scope support metadata
+
+Extend `AI_TOOLS` metadata with optional scope support declarations per surface:
+
+```ts
+interface ToolInstallScopeSupport {
+  skills?: InstallScope[];
+  commands?: InstallScope[];
+}
+```
+
+Resolution rules:
+
+1. If scope support metadata is absent for a tool surface, treat it as project-only support for conservative backward compatibility.
+2. Try preferred scope.
+3. If unsupported, use alternate scope when supported.
+4. If neither is supported, fail with actionable error.
+
+This enables default-global behavior while remaining safe for tools that only support project-local paths.
+
+### 3. Scope-aware install target resolver
+
+Introduce shared resolver utilities to compute effective target paths for:
+
+- skills root directory
+- command output files
+
+Resolver input:
+
+- tool id
+- requested scope
+- project root
+- environment context (`CODEX_HOME`, etc.)
+
+Resolver output:
+
+- effective scope per surface
+- concrete target paths
+- optional fallback reasons for user-facing output
+
+Platform behavior:
+
+- Resolver outputs are OS-aware and normalized for the current platform.
+- Windows global targets MUST use Windows path conventions (for example `%USERPROFILE%\.codex\prompts` fallback for Codex when `CODEX_HOME` is unset), not POSIX defaults.
+
+### 4. Context-aware command adapter paths
+
+Update command generation contract so adapters receive install context for path resolution. This avoids hardcoded absolute/relative assumptions and centralizes scope decisions.
+
+Example direction:
+
+```ts
+getFilePath(commandId: string, context: InstallContext): string
+```
+
+### 5. CLI behavior and UX
+
+`init`:
+
+- Uses configured install scope by default; if absent in a legacy config, uses migration-safe effective default (`project`).
+- Supports explicit override flag (`--scope global|project`).
+- In interactive mode, displays chosen scope and any per-tool fallback decisions before writing files.
+
+`update`:
+
+- Applies current scope preference (or override); if absent in a legacy config, uses migration-safe effective default (`project`).
+- Performs drift detection using effective scoped paths and last-applied scope state.
+- Reports effective scope decisions in summary output.
+
+`config`:
+
+- `openspec config profile` interactive flow includes install scope selection.
+- `openspec config list` shows `installScope` with source annotation (`explicit`, `new-default`, or `legacy-default`).
+
+### 6. Cleanup safety during scope changes
+
+When scope changes:
+
+- Writes occur in the new effective targets.
+- Cleanup/removal is limited to OpenSpec-managed files for the relevant tool/workflow IDs.
+- Output explicitly states which scope locations were updated and which were cleaned.
+
+### 7. Scope drift state tracking
+
+Track last successful effective scope per tool/surface in project-managed state.
+
+Rules:
+
+1. Drift is detected when current resolved scope differs from last successful scope for a configured tool/surface.
+2. Scope support MUST be validated for all configured tools/surfaces before any write starts.
+3. Update writes to newly resolved targets first, verifies completeness, then removes managed files at previous targets.
+4. If new-target writes are partial or verification fails, command SHALL abort old-target cleanup and report actionable failure with incomplete/new and preserved/old paths.
+5. Cleanup failures do not rollback new writes; command returns actionable failure with leftover paths to resolve.
+
+### 8. Coordination with command-surface capability changes
+
+If `add-tool-command-surface-capabilities` lands, planning logic must evaluate scope resolution and delivery/capability behavior together (scope × delivery × command surface).
+
+## Risks / Trade-offs
+
+**Risk: Cross-project shared global state**
+Global installs are shared across projects. Updating global artifacts from one project affects all projects using that tool scope.
+→ Mitigation: make scope explicit in output; keep profile/delivery global and deterministic.
+
+**Risk: Tool-specific unknown global conventions**
+Not all tools document a stable global install location.
+→ Mitigation: use explicit scope support metadata; fallback or fail instead of guessing.
+
+**Risk: Adapter API churn**
+Changing adapter path contracts touches many files/tests.
+→ Mitigation: migrate in one pass with adapter contract tests and existing end-to-end generation tests.
+
+## Rollout Plan
+
+1. Add config schema + defaults for install scope.
+2. Add tool scope capability metadata and resolver utilities.
+3. Upgrade command adapter contract and generator path plumbing.
+4. Integrate scope-aware behavior into init/update.
+5. Add documentation and test coverage.

+## Why
+
+OpenSpec installation paths are currently inconsistent:
+
+- Most skills and commands are written to project-local directories.
+- Codex commands are already global (`$CODEX_HOME/prompts` or `~/.codex/prompts`).
+- Users cannot choose a consistent install scope strategy across tools.
+
+This creates friction for users who prefer user-level setup and expect tool artifacts to be managed globally by default.
+
+## What Changes
+
+### 1. Add install scope preference with legacy-safe defaults
+
+Introduce a global install scope setting with two modes:
+
+- `global` (default for newly created configs)
+- `project`
+
+The setting is stored in global config and can be overridden per command run.
+For schema-evolved legacy configs where `installScope` is absent, effective default remains `project` until users opt in to global scope.
+
+### 2. Add scope-aware path resolution for skills and commands
+
+Refactor path resolution so both `init` and `update` compute install targets from:
+
+- selected scope preference (`global` or `project`)
+- tool capability metadata (which scopes each tool/surface supports)
+- runtime context (project root, home directories, env overrides)
+
+### 3. Add per-tool capability metadata for scope support
+
+Extend tool metadata to explicitly declare scope support per surface:
+
+- skills scope support
+- commands scope support
+
+When preferred scope is unsupported for a tool/surface, the system uses deterministic fallback rules and reports the effective scope in output.
+
+### 4. Make command generation context-aware
+
+Extend command adapter path resolution so adapters receive install context (scope + environment context), instead of only command ID. This removes special-case handling and allows consistent scope behavior across tools.
+
+### 5. Update init/update UX and behavior
+
+- `openspec init`:
+  - accepts scope override flag
+  - uses configured scope or migration-aware default (new configs default global; legacy configs preserve project until migration)
+  - applies scope-aware generation and cleanup planning
+- `openspec update`:
+  - applies current scope preference
+  - syncs artifacts in effective scope per tool/surface
+  - tracks last successful effective scope per tool/surface for deterministic scope-drift detection
+  - reports effective scope decisions clearly
+
+### 6. Extend config UX and docs
+
+- Add install scope control in `openspec config profile` interactive flow.
+- Extend `openspec config list` output with install scope source (`explicit`, `new-default`, `legacy-default`).
+- Add explicit migration guidance and prompt path so legacy users can opt into `global` scope.
+- Update supported tools and CLI docs to explain scope behavior and fallback rules.
+
+### 7. Coordinate with command-surface capability delivery rules
+
+`cli-init` and `cli-update` planning SHALL compose:
+
+- install scope (`global | project`)
+- delivery mode (`both | skills | commands`)
+- command surface capability (`adapter | skills-invocable | none`)
+
+This proposal remains focused on scope resolution, but implementation and test coverage should include mixed-tool cases to avoid regressions when combined with `add-tool-command-surface-capabilities`.
+
+## Capabilities
+
+### New Capabilities
+
+- `installation-scope`: Scope preference model and effective scope resolution for tool artifact installation.
+
+### Modified Capabilities
+
+- `global-config`: Persist install scope preference with schema evolution defaults.
+- `cli-config`: Configure and inspect install scope preferences.
+- `ai-tool-paths`: Add tool-level scope support metadata and path strategy.

+## Purpose
+
+Define the install scope model for OpenSpec-generated skills and commands, including scope preference, effective scope resolution, and fallback/error semantics.
+
+## ADDED Requirements
+
+### Requirement: Install scope preference model
+The system SHALL support a user-level install scope preference with values `global` and `project`.
+
+#### Scenario: Default install scope
+- **WHEN** install scope is not explicitly configured
+- **THEN** the system SHALL resolve a migration-aware default:
+- **AND** use `global` for newly created configs
+- **AND** use `project` for legacy schema-evolved configs until explicit migration
+
+#### Scenario: Explicit install scope
+- **WHEN** user configures install scope to `project`
+- **THEN** generation and update flows SHALL use `project` as the preferred scope
+
+### Requirement: Effective scope resolution by tool surface
+The system SHALL compute effective scope per tool surface (skills, commands) based on preferred scope and tool capability support.
+
+#### Scenario: Preferred scope is supported
+- **WHEN** preferred scope is supported for a tool surface
+- **THEN** the system SHALL use that scope as the effective scope
+
+#### Scenario: Preferred scope is unsupported but alternate is supported
+- **WHEN** preferred scope is not supported for a tool surface
+- **AND** the alternate scope is supported
+- **THEN** the system SHALL use the alternate scope as effective scope
+- **AND** SHALL record a fallback note for user-facing output
+
+#### Scenario: No supported scope
+- **WHEN** neither `global` nor `project` is supported for a tool surface
+- **THEN** the command SHALL fail before writing files
+- **AND** SHALL display actionable remediation
+
+### Requirement: Effective scope reporting
+The system SHALL report effective scope decisions in command output when they differ from the preferred scope.
+
+#### Scenario: Fallback reporting
+- **WHEN** fallback resolution occurs for any selected/configured tool surface
+- **THEN** init/update summaries SHALL include effective scope notes per affected tool
+
+### Requirement: Cross-platform path behavior
+Install scope resolution SHALL produce platform-correct target paths.
+
+#### Scenario: Global scope path on Windows
+- **WHEN** effective scope is `global`
+- **AND** the command runs on Windows
+- **THEN** resolved target paths SHALL use Windows path conventions and separators
+- **AND** SHALL NOT reuse POSIX-style home-relative defaults directly
+
+### Requirement: Cleanup safety for scope transitions
+Scope transitions SHALL update new targets first and clean old managed targets safely.
+
+#### Scenario: Automatic cleanup for managed files on scope change
+- **WHEN** update or init applies a scope transition for a configured tool/surface
+- **THEN** the system SHALL write new artifacts in the new effective scope before cleanup
+- **AND** SHALL automatically remove only OpenSpec-managed files in the previous effective scope
+
+#### Scenario: Cleanup scope boundaries
+- **WHEN** cleanup runs after a scope transition
+- **THEN** the system SHALL leave non-managed files untouched
+- **AND** SHALL limit removal scope to the affected tool/workflow-managed paths
+
+#### Scenario: Cleanup failure after successful writes
+- **WHEN** new artifacts were written successfully in the new scope
+- **AND** cleanup of old managed targets fails
+- **THEN** the command SHALL report failure with leftover cleanup paths
+- **AND** SHALL NOT rollback successfully written new-scope artifacts

+## Why
+
+We need a faster, more reliable way to manually validate CLI behavior changes like profile/delivery sync, migration behavior, and tool-detection UX.
+
+Today, manual review is mostly ad hoc: each developer sets up state differently, runs a different command order, and checks outputs informally. This makes regressions easy to miss and slows iteration on CLI UX work.
+
+An 80/20 solution is to add a lightweight smoke harness for deterministic non-interactive flows, plus a short manual checklist for interactive prompt behavior.
+
+## What Changes
+
+- Add a lightweight QA smoke harness for OpenSpec CLI behavior with isolated per-run sandbox state
+- Use `Makefile` targets as the primary entrypoint:
+  - `make qa` (default local QA entrypoint)
+  - `make qa-smoke` (deterministic non-interactive suite)
+  - `make qa-interactive` (prints/opens manual interactive checklist)
+- Implement smoke logic in a script (invoked by Make targets), not in Make itself
+- Ensure each scenario runs in an isolated sandbox with temporary `HOME`, `XDG_CONFIG_HOME`, `XDG_DATA_HOME`, and `CODEX_HOME`
+- Capture scenario artifacts for inspection (command output, exit code, and before/after filesystem state)
+- Add a focused scenario set for high-risk behavior:
+  - init core output generation
+  - non-interactive detected-tool behavior
+  - migration when profile is unset
+  - delivery cleanup (`both -> skills`, `both -> commands`)
+  - commands-only update detection
+  - new tool directory detection messaging
+  - invalid profile override validation
+- Add a short interactive checklist for keypress/prompt UX verification (Space toggle, Enter confirm, detected pre-selection)
+- Wire CI to run the smoke suite on Linux as a fast regression gate
+
+## Capabilities
+
+### New Capabilities
+
+- `qa-smoke-harness`: Deterministic, sandboxed CLI smoke validation with a single developer entrypoint
+
+### Modified Capabilities
+
+- `developer-qa-workflow`: Standardized local/CI QA flow for CLI behavior and migration-sensitive scenarios
+
+## Impact
+
+- `Makefile` - Add `qa`, `qa-smoke`, and `qa-interactive` targets
+- `scripts/qa-smoke.sh` (or equivalent) - Implement sandbox setup, scenario execution, and assertions
+- `docs/` - Add/update contributor-facing QA instructions and interactive checklist usage
+- CI workflow - Add smoke target execution as a lightweight regression gate

+
+### Requirement: Sandboxed Smoke Scenario Runner
+
+The smoke suite SHALL run CLI scenarios in isolated sandboxes so tests are repeatable and do not depend on machine-global state.
+
+#### Scenario: Scenario execution is environment-isolated
+
+- **WHEN** a smoke scenario runs
+- **THEN** it SHALL use temporary values for `HOME`, `XDG_CONFIG_HOME`, `XDG_DATA_HOME`, and `CODEX_HOME`
+- **AND** global config from the host machine SHALL NOT affect scenario outcomes
+
+#### Scenario: Scenario artifacts are captured for review
+
+- **WHEN** a smoke scenario completes
+- **THEN** the runner SHALL capture command output and exit status
+- **AND** SHALL capture enough filesystem state to inspect before/after behavior
+
+#### Scenario: High-risk workflow coverage exists
+
+- **WHEN** the smoke suite executes
+- **THEN** it SHALL include scenarios covering profile/delivery behavior and migration-sensitive flows
+- **AND** include at least:
+  - non-interactive tool detection
+  - migration when profile is unset
+  - delivery cleanup (`both -> skills`, `both -> commands`)
+  - commands-only update detection

-## Why
-Manual setup for new changes leads to formatting mistakes in spec deltas and slows agents who must recreate the same file skeletons for every proposal. A built-in scaffold command will generate compliant templates so assistants can focus on the change content instead of structure.

-- Add an `openspec scaffold <change-id>` CLI command that creates a change directory (if it does not already exist) with validated `proposal.md`, `tasks.md`, and spec delta templates.
-- Update CLI documentation and quick-reference guidance so agents discover the scaffold workflow before drafting files manually, including reminders on when to create spec deltas.
-- Add automated coverage (unit/integ tests) to ensure the command respects naming rules, copies templates correctly, fails for existing directories, and produces output that passes `openspec validate --strict` untouched.

+## Why
+
+OpenSpec currently assumes command delivery maps directly to command adapters. That assumption does not hold for all tools.
+
+Trae is a concrete example: it invokes OpenSpec workflows via skill entries (for example `/openspec-new-change`) rather than adapter-generated command files. In this model, skills are the command surface.
+
+Today, this creates a behavior gap:
+
+- `delivery=commands` can remove skills
+- tools without adapters skip command generation
+- result: selected tools like Trae can end up with no invocable workflow artifacts
+
+This is more than a prompt UX issue because non-interactive and CI flows bypass interactive guidance. We need a capability-aware model in core generation logic.
+
+## What Changes
+
+### 1. Add explicit command-surface capability metadata
+
+Add an optional field in tool metadata to describe how a tool exposes commands:
+
+- `adapter`: command files are generated through a command adapter
+- `skills-invocable`: skills are directly invocable as commands
+- `none`: no OpenSpec command surface
+
+Field should be optional. Default behavior is inferred from adapter registry presence: tools with a registered adapter resolve to `adapter`; tools with no adapter registration and no explicit annotation resolve to `none`.
+Capability values use kebab-case string tokens for consistency with serialized metadata conventions.
+
+Initial explicit override:
+
+- Trae -> `skills-invocable`
+
+### 2. Make delivery behavior capability-aware
+
+Update `init` and `update` to compute effective artifact actions per tool from:
+
+- global delivery (`both | skills | commands`)
+- tool command surface capability
+
+Behavior matrix:
+
+- `both`:
+  - generate skills for all tools with `skillsDir` (including `skills-invocable`)
+  - generate command files only for `adapter` tools
+  - `none`: no artifact action; MAY emit compatibility warning
+- `skills`:
+  - generate skills for all tools with `skillsDir` (including `skills-invocable`)
+  - remove adapter-generated command files
+  - `none`: no artifact action; MAY emit compatibility warning
+- `commands`:
+  - `adapter`: generate commands, remove skills
+  - `skills-invocable`: generate (or keep if up-to-date) skills as command surface; do not remove them
+  - `none`: fail fast with clear error
+
+### 3. Add preflight validation and clearer output
+
+Before writing/removing artifacts, validate selected/configured tools against delivery mode:
+
+- interactive flow: show clear compatibility note before confirmation
+- non-interactive flow: fail with deterministic error listing incompatible tools and supported alternatives
+
+Update summaries to show effective delivery outcomes per tool (for example, when commands mode still installs skills for skills-invocable tools).
+
+### 4. Update docs and tests
+
+- document capability model and Trae behavior under delivery modes
+- ensure CLI docs and supported-tools docs reflect effective behavior
+- add test coverage for:
+  - `init --tools trae` with `delivery=commands`
+  - `update` with Trae configured under `delivery=commands`
+  - mixed selections (`claude + trae`) across all delivery modes
+  - explicit error path for tools with no command surface under `delivery=commands`
+
+### 5. Coordinate with install-scope behavior
+
+When combined with `add-global-install-scope`, init/update planning must compose:
+
+- install scope (`global | project`)
+- delivery mode (`both | skills | commands`)
+- command surface capability (`adapter | skills-invocable | none`)
+
+Implementation tests should cover mixed-tool matrices to ensure deterministic behavior when both changes are active.
+
+## Capabilities
+
+### New Capabilities
+
+- `tool-command-surface`: Capability model that classifies tools as `adapter`, `skills-invocable`, or `none` to drive delivery behavior
+
+### Modified Capabilities
+
+- `cli-init`: Delivery handling becomes tool-capability-aware with preflight compatibility validation
+- `cli-update`: Delivery sync becomes tool-capability-aware with consistent compatibility validation and messaging
+- `supported-tools-docs`: Documents command-surface semantics for non-adapter tools
+
+## Impact
+
+- `src/core/config.ts` - add optional command-surface metadata and Trae override
+- `src/core/command-generation/registry.ts` (or shared helper) - capability inference from adapter presence
+- `src/core/init.ts` - capability-aware generation/removal planning + compatibility validation + summary messaging
+- `src/core/update.ts` - capability-aware sync/removal planning + compatibility validation + summary messaging
+- `src/core/shared/tool-detection.ts` - include capability-aware detection so `skills-invocable` tools remain detectable under `delivery=commands`, and `none` tools are excluded from command-surface artifact detection
+- `docs/supported-tools.md` and `docs/cli.md` - document delivery behavior and compatibility notes
+- `test/core/init.test.ts` and `test/core/update.test.ts` - add coverage for skills-invocable behavior and mixed-tool delivery scenarios
+
+## Sequencing Notes
+
+- This change is intended to stack safely with `simplify-skill-installation` by introducing additive, capability-specific requirements for init/update.
+- If `simplify-skill-installation` merges first, this change should be rebased and keep the capability-aware rule as the source of truth for `delivery=commands` behavior on `skills-invocable` tools.
+- If this change merges first, the `simplify-skill-installation` branch should be rebased to avoid re-introducing a global "commands-only means no skills for all tools" assumption.
+- If `add-global-install-scope` merges first, this change should be rebased to compose capability-aware behavior on top of scope-resolved path decisions from that change.
+- If this change merges first, `add-global-install-scope` should be rebased to preserve Section 5 composition rules (`install scope` + `delivery mode` + `command surface capability`) without overriding capability-aware command-surface outcomes.

+# Change Proposal: Extend Shell Completions
+
+## Why
+
+Zsh completions provide an excellent developer experience, but many developers use bash, fish, or PowerShell. Extending completion support to these shells removes friction for the majority of developers who don't use Zsh.
+
+## What Changes
+
+This change adds bash, fish, and PowerShell completion support following the same architectural patterns, documentation methodology, and testing rigor established for Zsh completions.
+
+## Deltas
+
+- **Spec:** `cli-completion`
+  - **Operation:** MODIFIED
+  - **Description:** Extend completion generation, installation, and testing requirements to support bash, fish, and PowerShell while maintaining the existing Zsh implementation and architectural patterns

+- **AND** each installer handles shell-specific paths, config files, and installation patterns
+
+#### Scenario: Factory pattern for shell selection
+
+- **WHEN** selecting shell-specific implementation
+- **THEN** use `CompletionFactory` class with static methods:
+  - `createGenerator(shell: SupportedShell): CompletionGenerator`

+- **AND** implement methods:
+  - `getChangeIds(): Promise<string[]>` - Discovers active change IDs
+  - `getSpecIds(): Promise<string[]>` - Discovers spec IDs
+  - `isOpenSpecProject(): boolean` - Checks if current directory is OpenSpec-enabled
+- **AND** implement caching with 2-second TTL using class properties
+
+#### Scenario: Command registry
+
+- **WHEN** defining completable commands
+- **THEN** create a centralized `CommandDefinition` type with properties:
+  - `name: string` - Command name
+  - `description: string` - Help text
+  - `flags: FlagDefinition[]` - Available flags
+  - `acceptsPositional: boolean` - Whether command takes positional arguments
+  - `positionalType: string` - Type of positional (change-id, spec-id, path, shell)
+  - `subcommands?: CommandDefinition[]` - Nested subcommands
+- **AND** export a `COMMAND_REGISTRY` constant with all command definitions
+- **AND** all generators consume this registry to ensure consistency across shells
+
+#### Scenario: Type-safe shell detection
+
+- **WHEN** implementing shell detection
+- **THEN** define a `SupportedShell` type as literal type: `'zsh' | 'bash' | 'fish' | 'powershell'`
+- **AND** implement `detectShell()` function in `src/utils/shell-detection.ts`
+- **AND** return detected shell or throw error with supported shells list
+
+### Requirement: Testing Support
+
+The completion implementation SHALL be testable with unit and integration tests for all supported shells.
+
+#### Scenario: Mock shell environment
+
+- **WHEN** writing tests for shell detection
+- **THEN** allow overriding `$SHELL` and `$PSModulePath` environment variables
+- **AND** use dependency injection for file system operations
+- **AND** test detection for all four shells independently
+
+#### Scenario: Generator output verification
+
+- **WHEN** testing completion generators
+- **THEN** create test suite for each shell generator (zsh, bash, fish, powershell)
+- **AND** verify generated scripts contain expected patterns for that shell
+- **AND** test that command registry is properly consumed
+- **AND** ensure dynamic completion placeholders are present
+- **AND** verify shell-specific syntax and escaping
+
+#### Scenario: Installer simulation
+
+- **WHEN** testing installation logic
+- **THEN** create test suite for each shell installer
+- **AND** use temporary test directories instead of actual home directories
+- **AND** verify file creation without modifying real shell configurations
+- **AND** test path resolution logic independently
+- **AND** mock file system operations to avoid side effects
+
+#### Scenario: Cross-shell consistency
+
+- **WHEN** testing completion behavior
+- **THEN** verify all shells support the same commands and flags
+- **AND** verify dynamic completions work consistently across shells
+- **AND** ensure error messages are consistent across shells

+## Context
+
+This implements "Slice 1: What's Ready?" from the artifact POC analysis. The core insight is using the filesystem as a database - artifact completion is detected by file existence, making the system stateless and version-control friendly.
+
+This module will coexist with the current OpenSpec system as a parallel capability, potentially enabling future migration or integration.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Pure dependency graph logic with no side effects
+- Stateless state detection (rescan filesystem each query)
+- Support glob patterns for multi-file artifacts (e.g., `specs/*.md`)
+- Load artifact definitions from YAML schemas
+- Calculate topological build order
+- Determine "ready" artifacts based on dependency completion
+
+**Non-Goals:**
+- CLI commands (Slice 4)
+- Multi-change management (Slice 2)
+- Template resolution and enrichment (Slice 3)
+- Agent integration or Claude commands
+- Replacing existing OpenSpec functionality
+
+## Decisions
+
+### Decision: Filesystem as Database
+Use file existence for state detection rather than a separate state file.
+
+**Rationale:**
+- Stateless - no state corruption possible
+- Git-friendly - state derived from committed files
+- Simple - no sync issues between state file and actual files
+
+**Alternatives considered:**
+- JSON/SQLite state file: More complex, sync issues, not git-friendly
+- Git metadata: Too coupled to git, complex implementation
+
+### Decision: Kahn's Algorithm for Topological Sort
+Use Kahn's algorithm for computing build order.
+
+**Rationale:**
+- Well-understood, O(V+E) complexity
+- Naturally detects cycles during execution
+- Produces a stable, deterministic order
+
+### Decision: Glob Pattern Support
+Support glob patterns like `specs/*.md` in artifact `generates` field.
+
+**Rationale:**
+- Allows multiple files to satisfy a single artifact requirement
+- Common pattern for spec directories with multiple files
+- Uses standard glob syntax
+
+### Decision: Immutable Completed Set
+Represent completion state as an immutable Set of completed artifact IDs.
+
+**Rationale:**
+- Functional style, easier to reason about
+- State derived fresh each query, no mutation needed
+- Clear separation between graph structure and runtime state
+- Filesystem can only detect binary existence (complete vs not complete)
+
+**Note:** `inProgress` and `failed` states are deferred to future slices. They would require external state tracking (e.g., a status file) since file existence alone cannot distinguish these states.
+
+### Decision: Zod for Schema Validation
+Use Zod for validating YAML schema structure and deriving TypeScript types.
+
+**Rationale:**
+- Already a project dependency (v4.0.17) used in `src/core/schemas/`
+- Type inference via `z.infer<>` - single source of truth for types
+- Runtime validation with detailed error messages
+- Consistent with existing project patterns (`base.schema.ts`, `config-schema.ts`)
+
+**Alternatives considered:**
+- Manual validation: More code, error-prone, no type inference
+- JSON Schema: Would require additional dependency, less TypeScript integration
+- io-ts: Not already in project, steeper learning curve
+
+### Decision: Two-Level Schema Resolution
+Schemas resolve from global user data directory, falling back to package built-ins.
+
+**Resolution order:**
+1. `${XDG_DATA_HOME:-~/.local/share}/openspec/schemas/<name>.yaml` - Global user override
+2. `<package>/schemas/<name>.yaml` - Built-in defaults
+
+**Rationale:**
+- Follows XDG Base Directory Specification (schemas are data, not config)
+- Mirrors existing `getGlobalConfigDir()` pattern in `src/core/global-paths.ts`
+- Built-ins baked into package, never auto-copied
+- Users customize by creating files in global data dir
+- Simple - no project-level overrides (can add later if needed)
+
+**XDG compliance:**
+- Uses `XDG_DATA_HOME` env var when set (all platforms)
+- Unix/macOS fallback: `~/.local/share/openspec/`
+- Windows fallback: `%LOCALAPPDATA%/openspec/`
+
+**Alternatives considered:**
+- Project-level overrides: Added complexity, not needed initially
+- Auto-copy to user space: Creates drift, harder to update defaults
+- Config directory (`XDG_CONFIG_HOME`): Schemas are workflow definitions (data), not user preferences (config)
+
+### Decision: Template Field Parsed But Not Resolved
+The `template` field is required in schema YAML for completeness, but template resolution is deferred to Slice 3.
+
+**Rationale:**
+- Slice 1 focuses on "What's Ready?" - dependency and completion queries only
+- Template paths are validated syntactically (non-empty string) but not resolved
+- Keeps Slice 1 focused and independently testable
+
+### Decision: Cycle Error Format
+Cycle errors list all artifact IDs in the cycle for easy debugging.
+
+**Format:** `"Cyclic dependency detected: A → B → C → A"`
+
+**Rationale:**
+- Shows the full cycle path, not just that a cycle exists
+- Actionable - developer can see exactly which artifacts to fix
+- Consistent with Kahn's algorithm which naturally identifies cycle participants
+
+## Data Structures
+
+**Zod Schemas (source of truth):**
+
+```typescript
+import { z } from 'zod';
+
+// Artifact definition schema
+export const ArtifactSchema = z.object({
+  id: z.string().min(1, 'Artifact ID is required'),
+  generates: z.string().min(1),      // e.g., "proposal.md" or "specs/*.md"
+  description: z.string(),
+  template: z.string(),              // path to template file
+  requires: z.array(z.string()).default([]),
+});
+
+// Full schema YAML structure
+export const SchemaYamlSchema = z.object({
+  name: z.string().min(1, 'Schema name is required'),
+  version: z.number().int().positive(),
+  description: z.string().optional(),
+  artifacts: z.array(ArtifactSchema).min(1, 'At least one artifact required'),
+});
+
+// Derived TypeScript types
+export type Artifact = z.infer<typeof ArtifactSchema>;
+export type SchemaYaml = z.infer<typeof SchemaYamlSchema>;
+```
+
+**Runtime State (not Zod - internal only):**
+
+```typescript
+// Slice 1: Simple completion tracking via filesystem
+type CompletedSet = Set<string>;
+
+// Return type for blocked query
+interface BlockedArtifacts {
+  [artifactId: string]: string[];  // artifact → list of unmet dependencies
+}
+
+interface ArtifactGraphResult {
+  completed: string[];
+  ready: string[];
+  blocked: BlockedArtifacts;
+  buildOrder: string[];
+}
+```
+

+- Global user override: `${XDG_DATA_HOME:-~/.local/share}/openspec/schemas/<name>.yaml`
+- Package built-in: `src/core/artifact-graph/schemas/<name>.yaml` (bundled with package)
+
+## Risks / Trade-offs
+
+| Risk | Mitigation |
+|------|------------|
+| Glob pattern edge cases | Use well-tested glob library (fast-glob or similar) |
+| Cycle detection | Kahn's algorithm naturally fails on cycles; provide clear error |
+| Schema evolution | Version field in schema, validate on load |

+## Why
+
+The current OpenSpec system relies on conventions and AI inference for artifact ordering. A formal artifact graph with dependency awareness would enable deterministic "what's ready?" queries, making the system more predictable and enabling future features like automated pipeline execution.
+
+## What Changes
+
+- Add `ArtifactGraph` class to model artifacts as a DAG with dependency relationships
+- Add `ArtifactState` type to track completion status (completed, in_progress, failed)
+- Add filesystem-based state detection using file existence and glob patterns
+- Add schema YAML parser to load artifact definitions
+- Implement topological sort (Kahn's algorithm) for build order calculation
+- Add `getNextArtifacts()` to find artifacts ready for creation
+
+## Impact
+
+- Affected specs: New `artifact-graph` capability
+- Affected code: `src/core/artifact-graph/` (new directory)
+- No changes to existing functionality - this is a parallel module

+## ADDED Requirements
+
+### Requirement: Schema Loading
+The system SHALL load artifact graph definitions from YAML schema files.
+
+#### Scenario: Valid schema loaded
+- **WHEN** a valid schema YAML file is provided
+- **THEN** the system returns an ArtifactGraph with all artifacts and dependencies
+
+#### Scenario: Invalid schema rejected
+- **WHEN** a schema YAML file is missing required fields
+- **THEN** the system throws an error with a descriptive message
+
+#### Scenario: Cyclic dependencies detected
+- **WHEN** a schema contains cyclic artifact dependencies
+- **THEN** the system throws an error listing the artifact IDs in the cycle
+
+#### Scenario: Invalid dependency reference
+- **WHEN** an artifact's `requires` array references a non-existent artifact ID
+- **THEN** the system throws an error identifying the invalid reference
+
+#### Scenario: Duplicate artifact IDs rejected
+- **WHEN** a schema contains multiple artifacts with the same ID
+- **THEN** the system throws an error identifying the duplicate
+
+### Requirement: Build Order Calculation
+The system SHALL compute a valid topological build order for artifacts.
+
+#### Scenario: Linear dependency chain
+- **WHEN** artifacts form a linear chain (A → B → C)
+- **THEN** getBuildOrder() returns [A, B, C]
+
+#### Scenario: Diamond dependency
+- **WHEN** artifacts form a diamond (A → B, A → C, B → D, C → D)
+- **THEN** getBuildOrder() returns A before B and C, and D last
+
+#### Scenario: Independent artifacts
+- **WHEN** artifacts have no dependencies
+- **THEN** getBuildOrder() returns them in a stable order
+
+### Requirement: State Detection
+The system SHALL detect artifact completion state by scanning the filesystem.
+
+#### Scenario: Simple file exists
+- **WHEN** an artifact generates "proposal.md" and the file exists
+- **THEN** the artifact is marked as completed
+
+#### Scenario: Simple file missing
+- **WHEN** an artifact generates "proposal.md" and the file does not exist
+- **THEN** the artifact is not marked as completed
+
+#### Scenario: Glob pattern with files
+- **WHEN** an artifact generates "specs/*.md" and the specs/ directory contains .md files
+- **THEN** the artifact is marked as completed
+
+#### Scenario: Glob pattern empty
+- **WHEN** an artifact generates "specs/*.md" and the specs/ directory is empty or missing
+- **THEN** the artifact is not marked as completed
+
+#### Scenario: Missing change directory
+- **WHEN** the change directory does not exist
+- **THEN** all artifacts are marked as not completed (empty state)
+
+### Requirement: Ready Artifact Query
+The system SHALL identify which artifacts are ready to be created based on dependency completion.
+
+#### Scenario: Root artifacts ready initially
+- **WHEN** no artifacts are completed
+- **THEN** getNextArtifacts() returns artifacts with no dependencies
+
+#### Scenario: Dependent artifact becomes ready
+- **WHEN** an artifact's dependencies are all completed
+- **THEN** getNextArtifacts() includes that artifact
+
+#### Scenario: Blocked artifacts excluded
+- **WHEN** an artifact has uncompleted dependencies
+- **THEN** getNextArtifacts() does not include that artifact
+
+### Requirement: Completion Check
+The system SHALL determine when all artifacts in a graph are complete.
+
+#### Scenario: All complete
+- **WHEN** all artifacts in the graph are in the completed set
+- **THEN** isComplete() returns true
+
+#### Scenario: Partially complete
+- **WHEN** some artifacts in the graph are not completed
+- **THEN** isComplete() returns false
+
+### Requirement: Blocked Query
+The system SHALL identify which artifacts are blocked and return all their unmet dependencies.
+
+#### Scenario: Artifact blocked by single dependency
+- **WHEN** artifact B requires artifact A and A is not complete
+- **THEN** getBlocked() returns `{ B: ['A'] }`
+
+#### Scenario: Artifact blocked by multiple dependencies
+- **WHEN** artifact C requires A and B, and only A is complete
+- **THEN** getBlocked() returns `{ C: ['B'] }`
+
+#### Scenario: Artifact blocked by all dependencies
+- **WHEN** artifact C requires A and B, and neither is complete
+- **THEN** getBlocked() returns `{ C: ['A', 'B'] }`

+## Context
+
+This is Slice 2 of the artifact tracker POC. The goal is to provide utilities for creating change directories programmatically.
+
+**Current state:** No programmatic way to create changes. Users must manually create directories.
+
+**Proposed state:** Utility functions for change creation with name validation.
+
+## Goals / Non-Goals
+
+### Goals
+- **Add** `createChange()` function to create change directories
+- **Add** `validateChangeName()` function for kebab-case validation
+- **Enable** automation (Claude commands, scripts) to create changes
+
+### Non-Goals
+- Refactor existing CLI commands (they work fine)
+- Create abstraction layers or manager classes
+- Change how `ListCommand` or `ChangeCommand` work
+
+## Decisions
+
+### Decision 1: Simple Utility Functions
+
+**Choice**: Add functions to `src/utils/change-utils.ts` - no class.
+
+```typescript
+// src/utils/change-utils.ts
+
+export function validateChangeName(name: string): { valid: boolean; error?: string }
+
+export async function createChange(
+  projectRoot: string,
+  name: string
+): Promise<void>
+```
+
+**Why**:
+- Simple, no abstraction overhead
+- Easy to test
+- Easy to import where needed
+- Matches existing utility patterns in `src/utils/`
+
+**Alternatives considered**:
+- ChangeManager class: Rejected - over-engineered for 2 functions
+- Add to existing command: Rejected - mixes CLI with reusable logic
+
+### Decision 2: Kebab-Case Validation Pattern
+
+**Choice**: Validate names with `^[a-z][a-z0-9]*(-[a-z0-9]+)*$`
+
+Valid: `add-auth`, `refactor-db`, `add-feature-2`, `refactor`
+Invalid: `Add-Auth`, `add auth`, `add_auth`, `-add-auth`, `add-auth-`, `add--auth`
+
+**Why**:
+- Filesystem-safe (no special characters)
+- URL-safe (for future web UI)
+- Consistent with existing change naming in repo
+
+## File Changes
+
+### New Files
+- `src/utils/change-utils.ts` - Utility functions
+- `src/utils/change-utils.test.ts` - Unit tests
+
+### Modified Files
+- None
+
+## Risks / Trade-offs
+
+| Risk | Mitigation |
+|------|------------|
+| Function might not cover all use cases | Start simple, extend if needed |
+| Naming conflicts with future work | Using clear, specific function names |

+## Why
+
+There's no programmatic way to create a new change directory. Users must manually:
+1. Create `openspec/changes/<name>/` directory
+2. Create a `proposal.md` file
+3. Hope they got the naming right
+
+This is error-prone and blocks automation (e.g., Claude commands, scripts).
+
+**This proposal adds:**
+1. `createChange(projectRoot, name)` - Create change directories programmatically
+2. `validateChangeName(name)` - Enforce kebab-case naming conventions
+
+## What Changes
+
+### New Utilities
+
+| Function | Description |
+|----------|-------------|
+| `createChange(projectRoot, name)` | Creates `openspec/changes/<name>/` directory |
+| `validateChangeName(name)` | Returns `{ valid: boolean; error?: string }` |
+
+### Name Validation Rules
+
+Pattern: `^[a-z][a-z0-9]*(-[a-z0-9]+)*$`
+
+| Valid | Invalid |
+|-------|---------|
+| `add-auth` | `Add-Auth` (uppercase) |
+| `refactor-db` | `add auth` (spaces) |
+| `add-feature-2` | `add_auth` (underscores) |
+| `refactor` | `-add-auth` (leading hyphen) |

+## Context
+
+Slice 4 of the artifact workflow POC. The core functionality (ArtifactGraph, InstructionLoader, change-utils) is complete. This slice adds CLI commands to expose the artifact workflow to users.
+
+**Key constraint**: This is experimental. Commands must be isolated for easy removal if the feature doesn't work out.
+
+## Goals / Non-Goals
+
+- **Goals:**
+  - Expose artifact workflow status and instructions via CLI
+  - Provide fluid UX with top-level verb commands
+  - Support both human-readable and JSON output
+  - Enable agents to programmatically query workflow state
+  - Keep implementation isolated for easy removal
+
+- **Non-Goals:**
+  - Interactive artifact creation wizards (future work)
+  - Schema management commands (deferred)
+  - Auto-detection of active change (CLI is deterministic, agents infer)
+
+## Decisions
+
+### Command Structure: Top-Level Verbs
+
+Commands are top-level for maximum fluidity:
+
+```
+openspec status --change <id>
+openspec next --change <id>
+openspec instructions <artifact> --change <id>
+openspec templates [--schema <name>]
+openspec new change <name>
+```
+
+**Rationale:**
+- Most fluid UX - fewest keystrokes
+- Commands are unique enough to avoid conflicts
+- Simple mental model for users
+
+**Trade-off accepted:** Slight namespace pollution, but commands are distinct and can be removed cleanly.
+
+### Experimental Isolation
+
+All artifact workflow commands are implemented in a single file:
+
+```
+src/commands/artifact-workflow.ts
+```
+
+**To remove the feature:**
+1. Delete `src/commands/artifact-workflow.ts`
+2. Remove ~5 lines from `src/cli/index.ts`
+
+No other files touched, no risk to stable functionality.
+
+### Deterministic CLI with Explicit `--change`
+
+All change-specific commands require `--change <id>`:
+
+```bash
+openspec status --change add-auth   # explicit, works
+openspec status                      # error: missing --change
+```
+
+**Rationale:**
+- CLI is pure, testable, no hidden state
+- Agents infer change from conversation and pass explicitly
+- No config file tracking "active change"
+- Consistent with POC design philosophy
+
+### New Change Command Structure
+
+Creating changes uses explicit subcommand:
+
+```bash
+openspec new change add-feature
+```
+
+**Rationale:**
+- `openspec new <name>` is ambiguous (new what?)
+- `openspec new change <name>` is clear and extensible
+- Can add `openspec new spec <name>` later if needed
+
+### Output Formats
+
+- **Default**: Human-readable text with visual indicators
+  - Status: `[x]` done, `[ ]` ready, `[-]` blocked
+  - Colors: green (done), yellow (ready), red (blocked)
+- **JSON** (`--json`): Machine-readable for scripts and agents
+
+### Error Handling
+
+- Missing `--change`: Error listing available changes
+- Unknown change: Error with suggestion
+- Unknown artifact: Error listing valid artifacts
+- Missing schema: Error with schema resolution details
+
+## Risks / Trade-offs
+
+| Risk | Mitigation |
+|------|------------|
+| Top-level commands pollute namespace | Commands are distinct; isolated for easy removal |
+| `status` confused with git | Context (`--change`) makes it clear |
+| Feature doesn't work out | Single file deletion removes everything |
+
+## Implementation Notes
+
+- All commands in `src/commands/artifact-workflow.ts`
+- Imports from `src/core/artifact-graph/` for all operations
+- Uses `getActiveChangeIds()` from `item-discovery.ts` for change listing
+- Follows existing CLI patterns (ora spinners, commander.js options)
+- Help text marks commands as "Experimental"

+## Why
+
+The ArtifactGraph (Slice 1) and InstructionLoader (Slice 3) provide programmatic APIs for artifact-based workflow management. Users currently have no CLI interface to:
+- See artifact completion status for a change
+- Discover what artifacts are ready to create
+- Get enriched instructions for creating artifacts
+- Create new changes with proper validation
+
+This proposal adds CLI commands that expose the artifact workflow functionality to users and agents.
+
+## What Changes
+
+- **NEW**: `openspec status --change <id>` shows artifact completion state
+- **NEW**: `openspec next --change <id>` shows artifacts ready to create
+- **NEW**: `openspec instructions <artifact> --change <id>` outputs enriched template
+- **NEW**: `openspec templates [--schema <name>]` shows resolved template paths
+- **NEW**: `openspec new change <name>` creates a new change directory
+
+All commands are top-level for fluid UX. They integrate with existing core modules:
+- Uses `loadChangeContext()`, `formatChangeStatus()`, `generateInstructions()` from instruction-loader
+- Uses `ArtifactGraph`, `detectCompleted()` from artifact-graph
+- Uses `createChange()`, `validateChangeName()` from change-utils
+
+**Experimental isolation**: All commands are implemented in a single file (`src/commands/artifact-workflow.ts`) for easy removal if the feature doesn't work out. Help text marks them as experimental.
+
+## Impact
+
+- Affected specs: NEW `cli-artifact-workflow` capability
+- Affected code:
+  - `src/cli/index.ts` - register new commands
+  - `src/commands/artifact-workflow.ts` - new command implementations
+- No changes to existing commands or specs
+- Builds on completed Slice 1, 2, and 3 implementations

+# cli-artifact-workflow Specification
+
+## Purpose
+CLI commands for artifact workflow operations, exposing the artifact graph and instruction loader functionality to users and agents. Commands are top-level for fluid UX and implemented in isolation for easy removal.
+
+## ADDED Requirements
+
+### Requirement: Status Command
+The system SHALL display artifact completion status for a change.
+
+#### Scenario: Show status with all states
+- **WHEN** user runs `openspec status --change <id>`
+- **THEN** the system displays each artifact with status indicator:
+  - `[x]` for completed artifacts
+  - `[ ]` for ready artifacts
+  - `[-]` for blocked artifacts (with missing dependencies listed)
+
+#### Scenario: Status shows completion summary
+- **WHEN** user runs `openspec status --change <id>`
+- **THEN** output includes completion percentage and count (e.g., "2/4 artifacts complete")
+
+#### Scenario: Status JSON output
+- **WHEN** user runs `openspec status --change <id> --json`
+- **THEN** the system outputs JSON with changeName, schemaName, isComplete, and artifacts array
+
+#### Scenario: Missing change parameter
+- **WHEN** user runs `openspec status` without `--change`
+- **THEN** the system displays an error with list of available changes
+
+#### Scenario: Unknown change
+- **WHEN** user runs `openspec status --change unknown-id`
+- **THEN** the system displays an error indicating the change does not exist
+
+### Requirement: Next Command
+The system SHALL show which artifacts are ready to be created.
+
+#### Scenario: Show ready artifacts
+- **WHEN** user runs `openspec next --change <id>`
+- **THEN** the system lists artifacts whose dependencies are all satisfied
+
+#### Scenario: No artifacts ready
+- **WHEN** all artifacts are either completed or blocked
+- **THEN** the system indicates no artifacts are ready (with explanation)
+
+#### Scenario: All artifacts complete
+- **WHEN** all artifacts in the change are completed
+- **THEN** the system indicates the change is complete
+
+#### Scenario: Next JSON output
+- **WHEN** user runs `openspec next --change <id> --json`
+- **THEN** the system outputs JSON array of ready artifact IDs
+
+### Requirement: Instructions Command
+The system SHALL output enriched instructions for creating an artifact.
+
+#### Scenario: Show enriched instructions
+- **WHEN** user runs `openspec instructions <artifact> --change <id>`
+- **THEN** the system outputs:
+  - Artifact metadata (ID, output path, description)
+  - Template content
+  - Dependency status (done/missing)
+  - Unlocked artifacts (what becomes available after completion)
+
+#### Scenario: Instructions JSON output
+- **WHEN** user runs `openspec instructions <artifact> --change <id> --json`
+- **THEN** the system outputs JSON matching ArtifactInstructions interface
+
+#### Scenario: Unknown artifact
+- **WHEN** user runs `openspec instructions unknown-artifact --change <id>`
+- **THEN** the system displays an error listing valid artifact IDs for the schema
+
+#### Scenario: Artifact with unmet dependencies
+- **WHEN** user requests instructions for a blocked artifact
+- **THEN** the system displays instructions with a warning about missing dependencies
+
+### Requirement: Templates Command
+The system SHALL show resolved template paths for all artifacts in a schema.
+
+#### Scenario: List template paths with default schema
+- **WHEN** user runs `openspec templates`
+- **THEN** the system displays each artifact with its resolved template path using the default schema
+
+#### Scenario: List template paths with custom schema
+- **WHEN** user runs `openspec templates --schema tdd`
+- **THEN** the system displays template paths for the specified schema
+
+#### Scenario: Templates JSON output
+- **WHEN** user runs `openspec templates --json`
+- **THEN** the system outputs JSON mapping artifact IDs to template paths
+
+#### Scenario: Template resolution source
+- **WHEN** displaying template paths
+- **THEN** the system indicates whether each template is from user override or package built-in
+
+### Requirement: New Change Command
+The system SHALL create new change directories with validation.
+
+#### Scenario: Create valid change
+- **WHEN** user runs `openspec new change add-feature`
+- **THEN** the system creates `openspec/changes/add-feature/` directory
+
+#### Scenario: Invalid change name
+- **WHEN** user runs `openspec new change "Add Feature"` with invalid name
+- **THEN** the system displays validation error with guidance
+
+#### Scenario: Duplicate change name
+- **WHEN** user runs `openspec new change existing-change` for an existing change
+- **THEN** the system displays an error indicating the change already exists
+
+#### Scenario: Create with description
+- **WHEN** user runs `openspec new change add-feature --description "Add new feature"`
+- **THEN** the system creates the change directory with description in README.md
+
+### Requirement: Schema Selection
+The system SHALL support custom schema selection for workflow commands.
+
+#### Scenario: Default schema
+- **WHEN** user runs workflow commands without `--schema`
+- **THEN** the system uses the "spec-driven" schema
+
+#### Scenario: Custom schema
+- **WHEN** user runs `openspec status --change <id> --schema tdd`
+- **THEN** the system uses the specified schema for artifact graph
+
+#### Scenario: Unknown schema
+- **WHEN** user specifies an unknown schema
+- **THEN** the system displays an error listing available schemas
+
+### Requirement: Output Formatting
+The system SHALL provide consistent output formatting.
+
+#### Scenario: Color output
+- **WHEN** terminal supports colors
+- **THEN** status indicators use colors: green (done), yellow (ready), red (blocked)
+
+#### Scenario: No color output
+- **WHEN** `--no-color` flag is used or NO_COLOR environment variable is set
+- **THEN** output uses text-only indicators without ANSI colors
+
+#### Scenario: Progress indication
+- **WHEN** loading change state takes time
+- **THEN** the system displays a spinner during loading
+
+### Requirement: Experimental Isolation
+The system SHALL implement artifact workflow commands in isolation for easy removal.
+
+#### Scenario: Single file implementation
+- **WHEN** artifact workflow feature is implemented
+- **THEN** all commands are in `src/commands/artifact-workflow.ts`
+
+#### Scenario: Help text marking
+- **WHEN** user runs `--help` on any artifact workflow command
+- **THEN** help text indicates the command is experimental

+## Context
+
+This is Slice 3 of the artifact-graph POC. We have:
+- `ArtifactGraph` class with graph operations (Slice 1)
+- `detectCompleted()` for filesystem-based state detection (Slice 1)
+- `resolveSchema()` for XDG schema resolution (Slice 1)
+- `createChange()` and `validateChangeName()` utilities (Slice 2)
+
+After `restructure-schema-directories` is implemented, schemas will be self-contained directories:
+```
+schemas/<name>/
+├── schema.yaml
+└── templates/
+    └── *.md
+```
+
+This proposal adds template loading and instruction enrichment on top of that structure.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Load templates from schema directories
+- Enrich templates with change-specific context (dependency status)
+- Format change status for CLI output
+
+**Non-Goals:**
+- Template authoring UI
+- Dynamic template compilation/execution
+- Caching (keep it stateless like the rest)
+
+## Decisions
+
+### 1. Pure functions over classes
+
+Follow the pattern in `resolver.ts` and `state.ts`. Use a simple `ChangeContext` interface with pure functions:
+
+```typescript
+interface ChangeContext {
+  changeName: string;
+  changeDir: string;
+  schemaName: string;
+  graph: ArtifactGraph;
+  completed: CompletedSet;
+}
+
+function loadChangeContext(projectRoot: string, changeName: string, schemaName?: string): ChangeContext
+function loadTemplate(schemaName: string, templatePath: string): string
+function getInstructions(artifactId: string, context: ChangeContext): string
+function formatStatus(context: ChangeContext): string
+```
+
+**Why:** Matches existing codebase patterns. Easier to test. No hidden state.
+
+### 2. Template resolution from schema directory
+
+Templates are loaded from the schema's `templates/` subdirectory:
+
+```typescript
+function loadTemplate(schemaName: string, templatePath: string): string {
+  const schemaDir = getSchemaDir(schemaName);  // From resolver.ts
+  const fullPath = path.join(schemaDir, 'templates', templatePath);
+  return fs.readFileSync(fullPath, 'utf-8');
+}
+```
+
+Resolution is handled by `getSchemaDir()` which already checks user override → package built-in.
+
+**Why:** Leverages existing schema resolution. Templates are co-located with schemas.
+
+### 3. Template path from artifact definition
+
+The artifact's `template` field is a path relative to the schema's `templates/` directory:
+
+```yaml
+artifacts:
+  - id: proposal
+    template: "proposal.md"  # → schemas/<schema>/templates/proposal.md
+```
+
+**Why:** Explicit, simple, no magic.
+
+### 4. Minimal context injection
+
+Templates are markdown. Injection prepends a header section with context:
+
+```markdown
+---
+change: add-auth
+artifact: proposal
+schema: spec-driven
+output: openspec/changes/add-auth/proposal.md
+---
+
+## Dependencies
+- [x] (none - this is a root artifact)
+
+## Next Steps
+After creating this artifact, you can work on: design, specs
+
+---
+
+[original template content...]
+```
+
+**Why:** Simple string concatenation. No template engine dependency. Clear separation.
+
+### 5. Status output format
+
+```markdown
+## Change: add-auth (spec-driven)
+
+| Artifact | Status | Output |
+|----------|--------|--------|
+| proposal | done | proposal.md |
+| specs | ready | specs/*.md |
+| design | blocked (needs: proposal) | design.md |
+| tasks | blocked (needs: specs, design) | tasks.md |
+```
+
+**Why:** Markdown table is readable in terminal and docs. Matches CLI output style.
+
+## File Structure
+
+```
+src/core/artifact-graph/
+├── index.ts              # Add new exports
+├── template.ts           # NEW: Template loading
+├── context.ts            # NEW: ChangeContext loading
+└── instructions.ts       # NEW: Enrichment and formatting
+```
+
+## Risks / Trade-offs
+
+**Dependency on restructure-schema-directories:**
+- This proposal requires the schema restructure to be done first
+- Mitigation: Clear dependency documented, implement in order
+
+**No template engine:**
+- Pro: Zero dependencies, simple code
+- Con: Limited expressiveness
+- Mitigation: Current use case only needs static templates + header injection
+
+## Migration Plan
+
+N/A - new capability, no existing code to migrate.
+
+## Open Questions
+
+None.

+## Why
+
+Slice 1 (artifact-graph) provides graph operations and state detection. Slice 2 (change-utils) provides change creation. We now need the ability to load templates for artifacts and enrich them with change-specific context so users/agents know what to create next.
+
+## What Changes
+
+- Add template resolution from schema directories (uses structure from `restructure-schema-directories`)
+- Add instruction enrichment that injects change context into templates
+- Add status formatting for CLI output
+- New `instruction-loader` capability
+
+## Dependencies
+
+- Requires `restructure-schema-directories` to be implemented first (schemas as directories with co-located templates)
+
+## Impact
+
+- Affected specs: New `instruction-loader` spec
+- Affected code: `src/core/artifact-graph/` (new files)
+- Builds on: `artifact-graph` (Slice 1), uses `ArtifactGraph`, `detectCompleted`, `resolveSchema`

+# instruction-loader Specification
+
+## Purpose
+Load templates from schema directories and enrich them with change-specific context for guiding artifact creation.
+
+## ADDED Requirements
+
+### Requirement: Template Loading
+The system SHALL load templates from schema directories.
+
+#### Scenario: Load template from schema directory
+- **WHEN** `loadTemplate(schemaName, templatePath)` is called
+- **THEN** the system loads the template from `schemas/<schemaName>/templates/<templatePath>`
+
+#### Scenario: Template file not found
+- **WHEN** a template file does not exist in the schema's templates directory
+- **THEN** the system throws an error with the template path
+
+### Requirement: Change Context Loading
+The system SHALL load change context combining graph and completion state.
+
+#### Scenario: Load context for existing change
+- **WHEN** `loadChangeContext(projectRoot, changeName)` is called for an existing change
+- **THEN** the system returns a context with graph, completed set, schema name, and change info
+
+#### Scenario: Load context with custom schema
+- **WHEN** `loadChangeContext(projectRoot, changeName, schemaName)` is called
+- **THEN** the system uses the specified schema instead of default
+
+#### Scenario: Load context for non-existent change directory
+- **WHEN** `loadChangeContext` is called for a non-existent change directory
+- **THEN** the system returns context with empty completed set
+
+### Requirement: Template Enrichment
+The system SHALL enrich templates with change-specific context.
+
+#### Scenario: Include artifact metadata
+- **WHEN** instructions are generated for an artifact
+- **THEN** the output includes change name, artifact ID, schema name, and output path
+
+#### Scenario: Include dependency status
+- **WHEN** an artifact has dependencies
+- **THEN** the output shows each dependency with completion status (done/missing)
+
+#### Scenario: Include unlocked artifacts
+- **WHEN** instructions are generated
+- **THEN** the output includes which artifacts become available after this one
+
+#### Scenario: Root artifact indicator
+- **WHEN** an artifact has no dependencies
+- **THEN** the dependency section indicates this is a root artifact
+
+### Requirement: Status Formatting
+The system SHALL format change status as readable output.
+
+#### Scenario: All artifacts completed
+- **WHEN** all artifacts are completed
+- **THEN** status shows all artifacts as "done"
+
+#### Scenario: Mixed completion status
+- **WHEN** some artifacts are completed
+- **THEN** status shows completed as "done", ready as "ready", blocked as "blocked"
+
+#### Scenario: Blocked artifact details
+- **WHEN** an artifact is blocked
+- **THEN** status shows which dependencies are missing
+
+#### Scenario: Include output paths
+- **WHEN** status is formatted
+- **THEN** each artifact shows its output path pattern

+## Context
+
+Built-in schemas are currently embedded as TypeScript objects:
+
+```typescript
+// src/core/artifact-graph/builtin-schemas.ts
+export const SPEC_DRIVEN_SCHEMA: SchemaYaml = {
+  name: 'spec-driven',
+  version: 1,
+  artifacts: [...]
+};
+```
+
+This doesn't support templates co-located with schemas. The instruction loader (Slice 3) needs templates, and the cleanest approach is self-contained schema directories.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Schemas as self-contained directories (schema.yaml + templates/)
+- User overrides via XDG data directory
+- Simple 2-level resolution (user → package)
+- Templates co-located with their schema
+
+**Non-Goals:**
+- Shared template fallback (intentionally avoiding complexity)
+- Runtime schema compilation
+- Schema inheritance
+
+## Decisions
+
+### 1. Directory structure
+
+Each schema is a directory containing `schema.yaml` and `templates/`:
+
+```
+<package>/schemas/
+├── spec-driven/
+│   ├── schema.yaml
+│   └── templates/
+│       ├── proposal.md
+│       ├── design.md
+│       ├── spec.md
+│       └── tasks.md
+└── tdd/
+    ├── schema.yaml
+    └── templates/
+        ├── spec.md
+        ├── test.md
+        ├── implementation.md
+        └── docs.md
+```
+
+**Why:** Self-contained like Helm charts. No cross-schema dependencies. Each schema owns its templates.
+
+### 2. Resolution order (2 levels)
+
+```
+1. ${XDG_DATA_HOME}/openspec/schemas/<name>/schema.yaml   # User override
+2. <package>/schemas/<name>/schema.yaml                    # Built-in
+3. Error (not found)
+```
+
+**Why:** Simple mental model. User can override entire schema directory or just parts.
+
+### 3. Template path in schema.yaml
+
+The `template` field is relative to the schema's `templates/` directory:
+
+```yaml
+# schemas/spec-driven/schema.yaml
+artifacts:
+  - id: proposal
+    template: "proposal.md"  # → schemas/spec-driven/templates/proposal.md
+```
+
+**Why:** Paths are relative to the schema, not a global templates directory.
+
+### 4. Resolve package directory via import.meta.url
+
+```typescript
+function getPackageSchemasDir(): string {
+  const currentFile = fileURLToPath(import.meta.url);
+  // Navigate from src/core/artifact-graph/ to package root
+  return path.join(path.dirname(currentFile), '..', '..', '..', 'schemas');
+}
+```
+
+**Why:** Works in ESM. No hardcoded paths.
+
+### 5. Keep schema.yaml format unchanged
+
+The YAML format stays the same - only the storage location changes:
+
+```yaml
+name: spec-driven
+version: 1
+description: Specification-driven development
+artifacts:
+  - id: proposal
+    generates: "proposal.md"
+    template: "proposal.md"
+    requires: []
+```
+
+**Why:** No breaking changes to schema format. Just moving from TS to YAML files.
+
+## Migration
+
+1. Create `schemas/` directory at package root
+2. Convert `SPEC_DRIVEN_SCHEMA` to `schemas/spec-driven/schema.yaml`
+3. Convert `TDD_SCHEMA` to `schemas/tdd/schema.yaml`
+4. Update `resolveSchema()` to load from directories
+5. Remove `builtin-schemas.ts`
+6. Update `listSchemas()` to scan directories
+
+## Risks / Trade-offs
+
+**File I/O at runtime:**
+- Previously schemas were in-memory objects
+- Now requires reading YAML files
+- Mitigation: Schemas are small, loaded once per operation
+
+**Package distribution:**
+- Must ensure `schemas/` directory is included in npm package
+- Add to `files` in package.json
+

+
+None.

+## Why
+
+Currently, built-in schemas are embedded as TypeScript objects in `builtin-schemas.ts`. This works for schemas but doesn't support co-located templates. To enable self-contained schema packages (schema + templates together), we need to restructure schemas as directories.
+
+## What Changes
+
+- **BREAKING (internal):** Move built-in schemas from embedded TS objects to actual directory structure
+- Schemas become directories containing `schema.yaml` + `templates/`
+- Update `resolveSchema()` to load from directory structure
+- Remove `builtin-schemas.ts` (replaced by file-based schemas)
+- Update resolution to check user dir → package dir
+
+## Impact
+
+- Affected specs: `artifact-graph` (schema resolution changes)
+- Affected code:
+  - Remove `src/core/artifact-graph/builtin-schemas.ts`
+  - Update `src/core/artifact-graph/resolver.ts`
+  - Add `schemas/` directory at package root
+- No external API changes (resolution still returns `SchemaYaml`)

+# Design: Unify Change State Model
+
+## Overview
+
+This change fixes two bugs with minimal disruption to the existing system:
+
+1. **View bug**: Empty changes incorrectly shown as "Completed"
+2. **Artifact workflow bug**: Commands fail on scaffolded changes
+
+## Key Design Decision: Two Systems, Two Purposes
+
+The task-based and artifact-based systems serve **different purposes** and should coexist:
+
+| System | Purpose | Used By |
+|--------|---------|---------|
+| **Task Progress** | Track implementation work | `openspec view`, `openspec list` |
+| **Artifact Progress** | Track planning/spec work | `openspec status`, `openspec next` |
+
+We do NOT merge these systems. Instead, we fix each to work correctly in its domain.
+
+## Change 1: Fix View Command
+
+### Current Logic (Buggy)
+
+```typescript
+// view.ts line 90
+if (progress.total === 0 || progress.completed === progress.total) {
+  completed.push({ name: entry.name });
+}
+```
+
+Problem: `total === 0` means "no tasks defined yet", not "all tasks done".
+
+### New Logic
+
+```typescript
+if (progress.total === 0) {
+  draft.push({ name: entry.name });
+} else if (progress.completed === progress.total) {
+  completed.push({ name: entry.name });
+} else {
+  active.push({ name: entry.name, progress });
+}
+```
+
+### View Output Change
+
+**Before:**
+```
+Completed Changes
+─────────────────
+  ✓ add-feature        (all tasks done - correct)
+  ✓ test-workflow      (no tasks - WRONG)
+```
+
+**After:**
+```
+Draft Changes
+─────────────────
+  ○ test-workflow      (no tasks yet)
+
+Active Changes
+─────────────────
+  ◉ add-scaffold       [████░░░░] 3/7 tasks
+
+Completed Changes
+─────────────────
+  ✓ add-feature        (all tasks done)
+```
+
+## Change 2: Fix Artifact Workflow Discovery
+
+### Current Logic (Buggy)
+
+```typescript
+// artifact-workflow.ts - validateChangeExists()
+const activeChanges = await getActiveChangeIds(projectRoot);
+if (!activeChanges.includes(changeName)) {
+  throw new Error(`Change '${changeName}' not found...`);
+}
+```
+
+Problem: `getActiveChangeIds()` requires `proposal.md`, but artifact workflow should work on empty directories to help create the first artifact.
+
+### New Logic
+
+```typescript
+async function validateChangeExists(changeName: string, projectRoot: string): Promise<string> {
+  const changePath = path.join(projectRoot, 'openspec', 'changes', changeName);
+
+  // Check directory existence directly, not proposal.md
+  if (!fs.existsSync(changePath) || !fs.statSync(changePath).isDirectory()) {
+    // List available changes for helpful error message
+    const entries = await fs.promises.readdir(
+      path.join(projectRoot, 'openspec', 'changes'),
+      { withFileTypes: true }
+    );
+    const available = entries
+      .filter(e => e.isDirectory() && e.name !== 'archive' && !e.name.startsWith('.'))
+      .map(e => e.name);
+
+    if (available.length === 0) {
+      throw new Error('No changes found. Create one with: openspec new change <name>');
+    }
+    throw new Error(`Change '${changeName}' not found. Available:\n  ${available.join('\n  ')}`);
+  }
+
+  return changeName;
+}
+```
+
+### Behavior Change
+
+```bash
+# Before
+$ openspec new change foo
+$ openspec status --change foo
+Error: Change 'foo' not found.
+
+# After
+$ openspec new change foo
+$ openspec status --change foo
+Change: foo
+Progress: 0/4 artifacts complete
+
+[ ] proposal
+[-] specs (blocked by: proposal)
+[-] design (blocked by: proposal)
+[-] tasks (blocked by: specs, design)
+```
+
+## What Stays the Same
+
+1. **`getActiveChangeIds()`** - Still requires `proposal.md` (used by validate, show)
+2. **`getArchivedChangeIds()`** - Unchanged
+3. **Active/Completed semantics** - Still based on task checkboxes
+4. **Validation** - Still requires `proposal.md` to have something to validate
+
+## File Changes
+
+| File | Change |
+|------|--------|
+| `src/core/view.ts` | Add draft category, fix completion logic |
+| `src/commands/artifact-workflow.ts` | Update `validateChangeExists()` to use directory existence |
+| `test/commands/artifact-workflow.test.ts` | Add tests for scaffolded changes |
+
+## Testing Strategy
+
+1. **Unit test**: `validateChangeExists()` with scaffolded change
+2. **View test**: Verify three categories render correctly
+3. **Manual test**: Full workflow from `new change` → `status` → `view`

+# Proposal: Unify Change State Model
+
+## Problem Statement
+
+Two bugs create inconsistent behavior when working with changes:
+
+### Bug 1: Empty changes shown as "Completed" in view
+
+```typescript
+// view.ts line 90
+if (progress.total === 0 || progress.completed === progress.total) {
+  completed.push({ name: entry.name });  // BUG: total === 0 ≠ completed
+}
+```
+
+Result: `openspec new change foo && openspec view` shows `foo` as "Completed" when it has no content.
+
+### Bug 2: Artifact workflow commands can't find scaffolded changes
+
+```typescript
+// item-discovery.ts - getActiveChangeIds()
+const proposalPath = path.join(changesPath, entry.name, 'proposal.md');
+await fs.access(proposalPath);  // Only returns changes WITH proposal.md
+```
+
+Result: `openspec status --change foo` says "not found" even though the directory exists.
+
+## Root Cause
+
+The system conflates two different concepts:
+
+| Concept | Question | Source of Truth |
+|---------|----------|-----------------|
+| **Planning Progress** | Are all spec documents created? | File existence (ArtifactGraph) |
+| **Implementation Progress** | Is the coding work done? | Task checkboxes (tasks.md) |
+
+## Proposed Solution
+
+### Fix 1: Add "Draft" state to view command
+
+Keep Active/Completed with their existing meanings, but fix the bug:
+
+| State | Criteria | Meaning |
+|-------|----------|---------|
+| **Draft** | No tasks.md OR `tasks.total === 0` | Still planning |
+| **Active** | `tasks.total > 0` AND `completed < total` | Implementing |
+| **Completed** | `tasks.total > 0` AND `completed === total` | Done |
+
+### Fix 2: Artifact workflow uses directory existence
+
+Update `validateChangeExists()` to check if the directory exists, not if `proposal.md` exists. This allows the artifact workflow to guide users through creating their first artifact.
+
+### Keep existing discovery functions
+
+`getActiveChangeIds()` continues to require `proposal.md` for backward compatibility with validation and other commands.
+
+## What Changes
+
+| Command | Before | After |
+|---------|--------|-------|
+| `openspec view` | Empty = "Completed" | Empty = "Draft" |
+| `openspec status --change X` | Requires proposal.md | Works on any directory |
+| `openspec validate X` | Requires proposal.md | Unchanged (still requires it) |
+
+## Breaking Changes
+
+### Minimal Breaking Change
+
+1. **`openspec view` output**: Empty changes move from "Completed" section to new "Draft" section
+
+### Non-Breaking
+
+- Active/Completed semantics unchanged (still task-based)
+- `getActiveChangeIds()` unchanged
+- `openspec validate` unchanged
+- Archived changes unaffected
+
+## Out of Scope
+
+- Merging task-based and artifact-based progress (they serve different purposes)
+- Changing what "Completed" means (it stays = all tasks done)
+- Adding artifact progress to view command (separate enhancement)
+- Shell tab completions for artifact workflow commands (not yet registered)
+
+## Related Commands Analysis
+
+| Command | Uses `getActiveChangeIds()` | Should include scaffolded? | Change needed? |
+|---------|-----------------------------|-----------------------------|----------------|
+| `openspec view` | No (reads dirs directly) | Yes → Draft section | **Yes** |
+| `openspec list` | No (reads dirs directly) | Yes (shows "No tasks") | No |
+| `openspec status/next/instructions` | Yes | Yes | **Yes** |
+| `openspec validate` | Yes | No (can't validate empty) | No |
+| `openspec show` | Yes | No (nothing to show) | No |
+| Tab completions | Yes | Future enhancement | No |
+
+## Success Criteria
+
+1. `openspec new change foo && openspec view` shows `foo` in "Draft" section
+2. `openspec new change foo && openspec status --change foo` works
+3. Changes with all tasks done still show as "Completed"
+4. All existing tests pass

+## MODIFIED Requirements
+
+### Requirement: Status Command
+
+The system SHALL display artifact completion status for a change, including scaffolded (empty) changes.
+
+> **Fixes bug**: Previously required `proposal.md` to exist via `getActiveChangeIds()`.
+
+#### Scenario: Show status with all states
+
+- **WHEN** user runs `openspec status --change <id>`
+- **THEN** the system displays each artifact with status indicator:
+  - `[x]` for completed artifacts
+  - `[ ]` for ready artifacts
+  - `[-]` for blocked artifacts (with missing dependencies listed)
+
+#### Scenario: Status shows completion summary
+
+- **WHEN** user runs `openspec status --change <id>`
+- **THEN** output includes completion percentage and count (e.g., "2/4 artifacts complete")
+
+#### Scenario: Status JSON output
+
+- **WHEN** user runs `openspec status --change <id> --json`
+- **THEN** the system outputs JSON with changeName, schemaName, isComplete, and artifacts array
+
+#### Scenario: Status on scaffolded change
+
+- **WHEN** user runs `openspec status --change <id>` on a change with no artifacts
+- **THEN** system displays all artifacts with their status
+- **AND** root artifacts (no dependencies) show as ready `[ ]`
+- **AND** dependent artifacts show as blocked `[-]`
+
+#### Scenario: Missing change parameter
+
+- **WHEN** user runs `openspec status` without `--change`
+- **THEN** the system displays an error with list of available changes
+- **AND** includes scaffolded changes (directories without proposal.md)
+
+#### Scenario: Unknown change
+
+- **WHEN** user runs `openspec status --change unknown-id`
+- **AND** directory `openspec/changes/unknown-id/` does not exist
+- **THEN** the system displays an error listing all available change directories
+
+### Requirement: Next Command
+
+The system SHALL show which artifacts are ready to be created, including for scaffolded changes.
+
+#### Scenario: Show ready artifacts
+
+- **WHEN** user runs `openspec next --change <id>`
+- **THEN** the system lists artifacts whose dependencies are all satisfied
+
+#### Scenario: No artifacts ready
+
+- **WHEN** all artifacts are either completed or blocked
+- **THEN** the system indicates no artifacts are ready (with explanation)
+
+#### Scenario: All artifacts complete
+
+- **WHEN** all artifacts in the change are completed
+- **THEN** the system indicates the change is complete
+
+#### Scenario: Next JSON output
+
+- **WHEN** user runs `openspec next --change <id> --json`
+- **THEN** the system outputs JSON array of ready artifact IDs
+
+#### Scenario: Next on scaffolded change
+
+- **WHEN** user runs `openspec next --change <id>` on a change with no artifacts
+- **THEN** system shows root artifacts (e.g., "proposal") as ready to create
+
+### Requirement: Instructions Command
+
+The system SHALL output enriched instructions for creating an artifact, including for scaffolded changes.
+
+#### Scenario: Show enriched instructions
+
+- **WHEN** user runs `openspec instructions <artifact> --change <id>`
+- **THEN** the system outputs:
+  - Artifact metadata (ID, output path, description)
+  - Template content
+  - Dependency status (done/missing)
+  - Unlocked artifacts (what becomes available after completion)
+
+#### Scenario: Instructions JSON output
+
+- **WHEN** user runs `openspec instructions <artifact> --change <id> --json`
+- **THEN** the system outputs JSON matching ArtifactInstructions interface
+
+#### Scenario: Unknown artifact
+
+- **WHEN** user runs `openspec instructions unknown-artifact --change <id>`
+- **THEN** the system displays an error listing valid artifact IDs for the schema
+
+#### Scenario: Artifact with unmet dependencies
+
+- **WHEN** user requests instructions for a blocked artifact
+- **THEN** the system displays instructions with a warning about missing dependencies
+
+#### Scenario: Instructions on scaffolded change
+
+- **WHEN** user runs `openspec instructions proposal --change <id>` on a scaffolded change
+- **THEN** system outputs template and metadata for creating the proposal
+- **AND** does not require any artifacts to already exist

+## Why
+
+With per-change schema metadata in place (see `add-per-change-schema-metadata`), agents can now create changes with different workflow schemas. However, the agent skills are still hardcoded to `spec-driven` artifacts and don't offer schema selection to users.
+
+## What Changes
+
+**Scope: Experimental artifact workflow agent skills**
+
+**Depends on:** `add-per-change-schema-metadata` (must be implemented first)
+
+- Update `openspec-new-change` skill to prompt user for schema selection
+- Update `openspec-continue-change` skill to work with any schema's artifacts
+- Update `openspec-apply-change` skill to handle schema-specific task structures
+- Add schema descriptions to help users choose appropriate workflow
+
+## Capabilities
+
+### Modified Capabilities
+- `cli-artifact-workflow`: Agent skills support dynamic schema selection
+
+## Impact
+
+- **Affected code**: `src/core/templates/skill-templates.ts`
+- **User experience**: Users can choose TDD, spec-driven, or future workflows when starting a change
+- **Agent behavior**: Skills read artifact list from schema rather than hardcoding
+- **Backward compatible**: Default remains `spec-driven` if user doesn't choose

+## Context
+
+The experimental artifact workflow supports multiple schemas (`spec-driven`, `tdd`), but schema selection must be passed on every command. This creates friction for agents and users.
+
+We need a lightweight metadata file to persist the schema choice per change.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Store schema choice once at change creation
+- Auto-detect schema in experimental workflow commands
+- Maintain backward compatibility (no metadata = default)
+- Validate metadata with Zod schema
+
+**Non-Goals:**
+- Migrate existing changes (they use default)
+- Extend to legacy commands
+- Store additional metadata beyond schema (keep minimal for now)
+
+## Decisions
+
+### Decision: Zod Schema Design
+
+The metadata file (`.openspec.yaml`) will be validated with this Zod schema:
+
+```typescript
+// src/core/artifact-graph/types.ts (or new metadata.ts)
+
+import { z } from 'zod';
+import { listSchemas } from './resolver.js';
+
+/**
+ * Schema for per-change metadata stored in .openspec.yaml
+ */
+export const ChangeMetadataSchema = z.object({
+  // Required: which workflow schema this change uses
+  schema: z.string().min(1, { message: 'schema is required' }).refine(
+    (val) => listSchemas().includes(val),
+    (val) => ({ message: `Unknown schema '${val}'. Available: ${listSchemas().join(', ')}` })
+  ),
+
+  // Optional: creation timestamp (ISO date string)
+  created: z.string().regex(/^\d{4}-\d{2}-\d{2}$/, {
+    message: 'created must be YYYY-MM-DD format'
+  }).optional(),
+});
+
+export type ChangeMetadata = z.infer<typeof ChangeMetadataSchema>;
+```
+
+**Rationale:**
+- `schema` is required and validated against available schemas at parse time
+- `created` is optional, ISO date format for consistency
+- Minimal fields - can extend later without breaking existing files
+- Follows existing codebase pattern (see `ArtifactSchema`, `SchemaYamlSchema`)
+
+### Decision: File Location and Format
+
+**Location:** `openspec/changes/<name>/.openspec.yaml`
+
+**Format:**
+```yaml
+schema: tdd
+created: 2025-01-05
+```
+
+**Alternatives considered:**
+- `change.yaml` - less hidden, but clutters directory
+- Frontmatter in `proposal.md` - couples to proposal existence
+- `openspec.json` - YAML matches existing schema files
+
+### Decision: Read/Write Functions
+
+```typescript
+// src/utils/change-metadata.ts
+
+import * as fs from 'node:fs';
+import * as path from 'node:path';
+import * as yaml from 'yaml';
+import { ChangeMetadataSchema, type ChangeMetadata } from '../core/artifact-graph/types.js';
+
+const METADATA_FILENAME = '.openspec.yaml';
+
+export function writeChangeMetadata(
+  changeDir: string,
+  metadata: ChangeMetadata
+): void {
+  // Validate before writing
+  const validated = ChangeMetadataSchema.parse(metadata);
+  const content = yaml.stringify(validated);
+  fs.writeFileSync(path.join(changeDir, METADATA_FILENAME), content);
+}
+
+export function readChangeMetadata(
+  changeDir: string
+): ChangeMetadata | null {
+  const metaPath = path.join(changeDir, METADATA_FILENAME);
+
+  if (!fs.existsSync(metaPath)) {
+    return null;
+  }
+
+  const content = fs.readFileSync(metaPath, 'utf-8');
+  const parsed = yaml.parse(content);
+
+  // Validate and return (throws ZodError if invalid)
+  return ChangeMetadataSchema.parse(parsed);
+}
+```
+
+### Decision: Schema Resolution Order
+
+When determining which schema to use:
+
+1. **Explicit `--schema` flag** (highest priority - user override)
+2. **`.openspec.yaml` metadata** (persisted choice)
+3. **Default `spec-driven`** (fallback)
+
+```typescript
+function resolveSchemaForChange(
+  changeDir: string,
+  explicitSchema?: string
+): string {
+  if (explicitSchema) return explicitSchema;
+
+  const metadata = readChangeMetadata(changeDir);
+  if (metadata?.schema) return metadata.schema;
+
+  return 'spec-driven';
+}
+```
+
+## Risks / Trade-offs
+
+- **Extra file per change** → Minimal overhead, hidden file
+- **YAML parsing dependency** → Already using `yaml` package for schema files
+- **Schema validation at read time** → Fail fast with clear error if corrupted
+
+## Migration Plan
+
+No migration needed:
+- Existing changes without `.openspec.yaml` continue to work (use default)
+- New changes created with `openspec new change --schema X` get metadata file
+
+## Open Questions
+
+- Should `openspec new change` prompt for schema interactively if not specified? (Leaning no - default is fine)

+## Why
+
+Currently, the schema (workflow type) must be passed via `--schema` flag on every experimental workflow command. This is repetitive and error-prone. Agents have no way to know which schema a change uses, so they default to `spec-driven` and cannot leverage alternative workflows like `tdd`.
+
+## What Changes
+
+**Scope: Experimental artifact workflow only** (`openspec new change`, `openspec status`, `openspec instructions`, `openspec templates`)
+
+- Store schema choice in `.openspec.yaml` metadata file when creating a change via `openspec new change`
+- Auto-detect schema from metadata in experimental workflow commands
+- Make `--schema` flag optional (override only, metadata takes precedence)
+- Add `--schema` option to `openspec new change` command
+
+**Not affected**: Legacy commands (`openspec validate`, `openspec archive`, `openspec list`, `openspec show`)

+## Capabilities

+### Modified Capabilities
+- `cli-artifact-workflow`: Commands auto-detect schema from change metadata
+
+## Impact
+
+- **Affected code**: `src/utils/change-utils.ts`, `src/core/artifact-graph/instruction-loader.ts`, `src/commands/artifact-workflow.ts`
+- **Agent skills**: Can be simplified - no longer need to pass schema explicitly
+- **Backward compatible**: Changes without `.openspec.yaml` fall back to `spec-driven` default
+- **Isolation**: All changes contained within experimental workflow code; legacy commands untouched

+## ADDED Requirements
+
+### Requirement: Change Metadata
+
+The system SHALL store and validate per-change metadata in `.openspec.yaml` files using a Zod schema.
+
+#### Scenario: Metadata file created with new change
+
+- **WHEN** user runs `openspec new change add-feature --schema tdd`
+- **THEN** the system creates `.openspec.yaml` in the change directory
+- **AND** the file contains `schema: tdd` and `created: <YYYY-MM-DD>`
+
+#### Scenario: Metadata validated on read
+
+- **WHEN** the system reads `.openspec.yaml`
+- **AND** the `schema` field references an unknown schema
+- **THEN** the system displays a validation error listing available schemas
+
+#### Scenario: Metadata schema validation
+
+- **WHEN** `.openspec.yaml` contains invalid YAML or missing required fields
+- **THEN** the system displays a Zod validation error with details
+
+#### Scenario: Missing metadata file
+
+- **WHEN** a change directory has no `.openspec.yaml` file
+- **THEN** the system falls back to the default schema (`spec-driven`)
+
+## MODIFIED Requirements
+
+### Requirement: New Change Command
+
+The system SHALL create new change directories with validation and optional schema metadata.
+
+#### Scenario: Create valid change
+
+- **WHEN** user runs `openspec new change add-feature`
+- **THEN** the system creates `openspec/changes/add-feature/` directory
+- **AND** creates `.openspec.yaml` with `schema: spec-driven` (default)
+
+#### Scenario: Create change with schema
+
+- **WHEN** user runs `openspec new change add-feature --schema tdd`
+- **THEN** the system creates `openspec/changes/add-feature/` directory
+- **AND** creates `.openspec.yaml` with `schema: tdd`
+
+#### Scenario: Invalid schema on create
+
+- **WHEN** user runs `openspec new change add-feature --schema unknown`
+- **THEN** the system displays an error listing available schemas
+- **AND** does not create the change directory
+
+#### Scenario: Invalid change name
+
+- **WHEN** user runs `openspec new change "Add Feature"` with invalid name
+- **THEN** the system displays validation error with guidance
+
+#### Scenario: Duplicate change name
+
+- **WHEN** user runs `openspec new change existing-change` for an existing change
+- **THEN** the system displays an error indicating the change already exists
+
+#### Scenario: Create with description
+
+- **WHEN** user runs `openspec new change add-feature --description "Add new feature"`
+- **THEN** the system creates the change directory with description in README.md
+
+### Requirement: Schema Selection
+
+The system SHALL support custom schema selection for workflow commands, with automatic detection from change metadata.
+
+#### Scenario: Schema auto-detected from metadata
+
+- **WHEN** user runs `openspec status --change <id>` without `--schema`
+- **AND** the change has `.openspec.yaml` with `schema: tdd`
+- **THEN** the system uses the `tdd` schema
+
+#### Scenario: Explicit schema overrides metadata
+
+- **WHEN** user runs `openspec status --change <id> --schema spec-driven`
+- **AND** the change has `.openspec.yaml` with `schema: tdd`
+- **THEN** the system uses `spec-driven` (explicit flag wins)
+
+#### Scenario: Default schema fallback
+
+- **WHEN** user runs workflow commands without `--schema`
+- **AND** the change has no `.openspec.yaml` file
+- **THEN** the system uses the "spec-driven" schema
+
+#### Scenario: Custom schema via flag
+
+- **WHEN** user runs `openspec status --change <id> --schema tdd`
+- **THEN** the system uses the specified schema for artifact graph
+
+#### Scenario: Unknown schema
+
+- **WHEN** user specifies an unknown schema
+- **THEN** the system displays an error listing available schemas
