refactor: use ENOTDIR approach for cross-platform install error tests

Instead of platform-specific invalid paths (Z:\ or /root), create a
temporary file and use it as homeDir. This guarantees deterministic
ENOTDIR failures when trying to create subdirectories on all platforms.

-# OpenSpec Rules for Cursor Agents
-
-Instructions for AI coding assistants using OpenSpec for spec-driven development.
-
-## 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
-
-Skip proposal for:
-- Bug fixes (restore intended behavior)
-- Typos, formatting, comments
-- Dependency updates (non-breaking)
-- Configuration changes
-- Tests for existing behavior
-
-### Stage 2: Implementing Changes
-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. **Mark complete immediately** - Update `- [x]` after each task
-
-### 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] --skip-specs` for tooling-only changes
-
-## 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
-
-## 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 diff [change]         # Show spec differences
-openspec validate [item]       # Validate changes or specs
-openspec archive [change]      # Archive after deployment
-
-# 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
-
-## Directory Structure
-
-```
-openspec/
-├── project.md              # Project conventions
-├── specs/                  # Current truth - what IS built
-│   └── [capability]/       # Single focused capability
-│       ├── spec.md         # Requirements and scenarios
-│       └── design.md       # Technical patterns

-│   │           └── spec.md # ADDED/MODIFIED/REMOVED
-│   └── archive/            # Completed changes
-```
-
-## 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/[descriptive-name]/`
-
-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]
-```
-
-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
-```
-
-## 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.
-
-### 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.
-
-## 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
-```
-
-## 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"
-
-## 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 diff [change]     # What's changing?
-openspec validate --strict # Is it correct?
-openspec archive [change]  # Mark complete
-```
-
-Remember: Specs are truth. Changes are proposals. Keep them in sync.

+# Dev Container Setup
+
+This directory contains the VS Code dev container configuration for OpenSpec development.
+
+## What's Included
+
+- **Node.js 20 LTS** (>=20.19.0) - TypeScript/JavaScript runtime
+- **pnpm** - Fast, disk space efficient package manager
+- **Git + GitHub CLI** - Version control tools
+- **VS Code Extensions**:
+  - ESLint & Prettier for code quality
+  - Vitest Explorer for running tests
+  - GitLens for enhanced git integration
+  - Error Lens for inline error highlighting
+  - Code Spell Checker
+  - Path IntelliSense
+
+## How to Use
+
+### First Time Setup
+
+1. **Install Prerequisites** (on your local machine):
+   - [VS Code](https://code.visualstudio.com/)
+   - [Docker Desktop](https://www.docker.com/products/docker-desktop)
+   - [Dev Containers extension](https://marketplace.visualstudio.com/items?itemName=ms-vscode-remote.remote-containers)
+
+2. **Open in Container**:
+   - Open this project in VS Code
+   - You'll see a notification: "Folder contains a Dev Container configuration file"
+   - Click "Reopen in Container"
+
+   OR
+
+   - Open Command Palette (`Cmd/Ctrl+Shift+P`)
+   - Type "Dev Containers: Reopen in Container"
+   - Press Enter
+
+3. **Wait for Setup**:
+   - The container will build (first time takes a few minutes)
+   - `pnpm install` runs automatically via `postCreateCommand`
+   - All extensions install automatically
+
+### Daily Development
+
+Once set up, the container preserves your development environment:
+
+```bash
+# Run development build
+pnpm run dev
+
+# Run CLI in development
+pnpm run dev:cli
+
+# Run tests
+pnpm test
+
+# Run tests in watch mode
+pnpm test:watch
+
+# Build the project
+pnpm run build
+```
+
+### SSH Keys
+
+Your SSH keys are mounted read-only from `~/.ssh`, so git operations work seamlessly with GitHub/GitLab.
+
+### Rebuilding the Container
+
+If you modify `.devcontainer/devcontainer.json`:
+- Command Palette → "Dev Containers: Rebuild Container"
+
+## Benefits
+
+- No need to install Node.js or pnpm on your local machine
+- Consistent development environment across team members
+- Isolated from other Node.js projects on your machine
+- All dependencies and tools containerized
+- Easy onboarding for new developers
+
+## Troubleshooting
+
+**Container won't build:**
+- Ensure Docker Desktop is running
+- Check Docker has enough memory allocated (recommend 4GB+)
+
+**Extensions not appearing:**
+- Rebuild the container: "Dev Containers: Rebuild Container"
+
+**Permission issues:**
+- The container runs as the `node` user (non-root)
+- Files created in the container are owned by this user

-# OpenSpec Project
+# OpenSpec Instructions
 
-This document provides instructions for AI coding assistants on how to use OpenSpec conventions for spec-driven development. Follow these rules precisely when working on OpenSpec-enabled projects.
+These instructions are for AI assistants working in this project.
 
-This project uses OpenSpec for spec-driven development. Specifications are the source of truth.
+Always open `@/openspec/AGENTS.md` when the request:
+- Mentions planning or proposals (words like proposal, spec, change, plan)
+- Introduces new capabilities, breaking changes, architecture shifts, or big performance/security work
+- Sounds ambiguous and you need the authoritative spec before coding
+
+Use `@/openspec/AGENTS.md` to learn:
+- How to create and apply change proposals
+- Spec format and conventions
+- Project structure and guidelines
+
+Keep this managed block so 'openspec update' can refresh the instructions.
 
-See @openspec/AGENTS.md for detailed conventions and guidelines.
 <!-- OPENSPEC:END -->
-
-## Complexity Management
-
-**Default to minimal solutions:**
-- Propose <100 lines of new code for features
-- Prefer single-file implementations until proven insufficient
-- Avoid frameworks, abstractions, and optimizations without clear justification
-- Choose boring, well-understood patterns over novel approaches
-
-**Question requests for complexity:**
-- Caching? → Ask for performance data and targets
-- New framework? → Suggest plain code first
-- Extra layers? → Start with the thinnest viable design
-
-**Justify complexity with data:**
-- Performance metrics showing current solution is too slow
-- Concrete scale requirements (e.g., >1000 users, >100MB data)
-- Multiple proven use cases requiring an abstraction
-
-## Package Manager
-Always use pnpm (NOT npm or yarn) for all Node.js package management:
-- Install dependencies: `pnpm install`
-- Add packages: `pnpm add [package]`
-- Run scripts: `pnpm run [script]`
-
-## Git Commits
-Use conventional commits with these rules:
-- Format: `type(scope): subject` (e.g., `fix: resolve auth error`, `feat(api): add user endpoint`)
-- Keep commit messages to ONE line only - no body or footer
-- Common types: feat, fix, docs, style, refactor, test, chore
-- Never add co-authorship lines or attribution

 # @fission-ai/openspec
 
+## 0.18.0
+
+### Minor Changes
+
+- 8dfd824: Add OPSX experimental workflow commands and enhanced artifact system
+
+  **New Commands:**
+
+  - `/opsx:ff` - Fast-forward through artifact creation, generating all needed artifacts in one go
+  - `/opsx:sync` - Sync delta specs from a change to main specs
+  - `/opsx:archive` - Archive completed changes with smart sync check
+
+  **Artifact Workflow Enhancements:**
+
+  - Schema-aware apply instructions with inline guidance and XML output
+  - Agent schema selection for experimental artifact workflow
+  - Per-change schema metadata via `.openspec.yaml` files
+  - Agent Skills for experimental artifact workflow
+  - Instruction loader for template loading and change context
+  - Restructured schemas as directories with templates
+
+  **Improvements:**
+
+  - Enhanced list command with last modified timestamps and sorting
+  - Change creation utilities for better workflow support
+
+  **Fixes:**
+
+  - Normalize paths for cross-platform glob compatibility
+  - Allow REMOVED requirements when creating new spec files
+
+## 0.17.2
+
+### Patch Changes
+
+- 455c65f: Fix `--no-interactive` flag in validate command to properly disable spinner, preventing hangs in pre-commit hooks and CI environments
+
+## 0.17.1
+
+### Patch Changes
+
+- a2757e7: Fix pre-commit hook hang issue in config command by using dynamic import for @inquirer/prompts
+
+  The config command was causing pre-commit hooks to hang indefinitely due to stdin event listeners being registered at module load time. This fix converts the static import to a dynamic import that only loads inquirer when the `config reset` command is actually used interactively.
+
+  Also adds ESLint with a rule to prevent static @inquirer imports, avoiding future regressions.

-**Supported AI Tools:** ✅ Claude Code | 🔜 Cursor (coming soon) | 🔜 AGENTS.md support (coming soon)
-
-Create **alignment** between humans and AI coding assistants through spec-driven development. **No API keys required.**
-
-OpenSpec ensures you and your AI assistant agree on what to build before any code is written. By discussing and refining specifications first, you bring determinism to AI code generation, getting exactly what you want, not what the AI thinks you might want.
+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?
 
-**The Problem:** AI coding assistants are powerful but unpredictable. Without clear specifications, they generate code based on assumptions, often missing requirements or adding unwanted features. Teams waste time in review cycles because humans and AI aren't aligned on what to build.
+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.
 
-**The Solution:** OpenSpec creates alignment BEFORE code is written:
-- **Human-AI Alignment** - You and your AI agree on specifications before implementation
-- **Deterministic Output** - Clear specs lead to predictable code generation
-- **Team Alignment** - Everyone reviews specs, not code surprises
-- **Focus on What, Not How** - Define requirements while AI handles implementation
-- **Living Documentation** - Specs evolve with your code as a natural byproduct
+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.
 
-## What You Get
+## How OpenSpec compares (at a glance)
 
-- **Alignment First** - Ensure humans and AI agree on what to build before writing code
-- **Predictable AI Output** - Turn non-deterministic AI into a reliable development partner
-- **Universal Tool Support** - Works with any AI assistant - Claude Code, Cursor, or future tools
-- **No API Keys Required** - Integrates through context rules, not external services
-- **Spec-Level Reviews** - Teams review intentions, not implementation details
-- **Clear Feature Scope** - Know exactly what you're building and what you're not
-- **Progress Tracking** - See what's proposed, in progress, or completed 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).

-### 2. Create Your First Change
+**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
 
-Jump straight into creating a change proposal with your AI assistant (works with Claude Code, Cursor, or any AI tool):
+**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
 
-```markdown
-// Quick win - Add a simple new feature:
-You: "I want to add a user profile API endpoint.
-      Please create an OpenSpec change proposal for this."
+### Optional: Populate Project Context
 
-AI: "I'll create an OpenSpec change proposal for the user profile API..."
-    *Creates openspec/changes/add-user-profile-api/ with:*
-    - proposal.md (why this feature is needed)
-    - tasks.md (implementation checklist)
-    - design.md (API design decisions)
-    - specs/user-profile/spec.md (new requirements)
+After `openspec init` completes, you'll receive a suggested prompt to help populate your project context:
 
-You: "The proposal looks good. Let's implement it."
-
-AI: "Following the tasks in openspec/changes/add-user-profile-api/tasks.md:
-     Task 1.1: Create user profile model..."
-    *Implements each task systematically*
+```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"
 ```
 
-### 3. Track Your Work
+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
-# View active changes (what's being worked on)
-openspec list
-
-# Validate your changes are properly formatted
-openspec validate add-2fa --strict
-
-# After deployment, archive the completed change
-openspec archive add-2fa
-# This moves the change to archive/ and updates specs/
+$ 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
 ```
 
-## Common Commands
+#### 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
-# Most used:
-openspec list              # See what changes you're working on
-openspec archive <change>  # Mark a change as complete after deployment
-
-# Also useful:
-openspec validate <change> # Check formatting before committing
-openspec show <change>     # View change details
+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

-## Why OpenSpec Works
-
-OpenSpec creates **alignment** between you and your AI coding assistant:
-
-1. **You describe** what you want to build
-2. **AI creates specs** before writing any code
-3. **You review and adjust** the specifications
-4. **AI implements** exactly what was specified
-5. **Everyone understands** what's being built through clear specs
-
-**True Interoperability:** OpenSpec is designed to be universal. No API keys, no vendor lock-in. It works by adding context rules to ANY AI coding tool - whether you use Claude Code today, switch to Cursor tomorrow, or adopt the next breakthrough AI assistant. Your specs remain portable and your workflow stays consistent.

 ## 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 all changes for a feature in one place (`openspec/changes/feature-name/`), making it easy to track what needs to be done. Kiro spreads changes across multiple spec folders, making feature tracking harder.
+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 based on vague prompts, often missing requirements or adding unwanted features. OpenSpec ensures alignment before any code is written.

 ## Team Adoption
 
-### Getting Started with Your Team
+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.
 
-1. **Initialize OpenSpec** - Run `openspec init` in your project
-2. **Start with new features** - Use OpenSpec for your next change proposal
-3. **Build incrementally** - Each new feature adds to your spec library
-4. **Future capability** - We're working on tools to generate specs from existing code
+Run `openspec update` whenever someone switches tools so your agents pick up the latest instructions and slash-command bindings.
 
-**Tool Freedom:** Your team can use different AI assistants. One developer might use Claude Code while another uses Cursor - OpenSpec keeps everyone aligned through shared specifications. Run `openspec update` to configure for any supported tool without affecting others.
+## 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.

+## Design Decisions & Terminology
+
+### Philosophy: Not a Workflow System
+
+This system is **not** a workflow engine. It's an **artifact tracker with dependency awareness**.
+
+| What it's NOT | What it IS |
+|---------------|------------|
+| Linear step-by-step progression | Exploratory, iterative planning |
+| Bureaucratic checkpoints | Enablers that unlock possibilities |
+| "You must complete step 1 first" | "Here's what you could create now" |
+| Form-filling | Fluid document creation |
+
+**Key insight:** Dependencies are *enablers*, not *gates*. You can't meaningfully write a design document if there's no proposal to design from - that's not bureaucracy, it's logic.
+
+### Terminology
+
+| Term | Definition | Example |
+|------|------------|---------|
+| **Change** | A unit of work being planned (feature, refactor, migration) | `openspec/changes/add-auth/` |
+| **Schema** | An artifact graph definition (what artifacts exist, their dependencies) | `spec-driven.yaml` |
+| **Artifact** | A node in the graph (a document to create) | `proposal`, `design`, `specs` |
+| **Template** | Instructions/guidance for creating an artifact | `templates/proposal.md` |
+
+### Hierarchy
+
+```
+Schema (defines) ──→ Artifacts (guided by) ──→ Templates
+```
+
+- **Schema** = the artifact graph (what exists, dependencies)
+- **Artifact** = a document to produce
+- **Template** = instructions for creating that artifact
+
+### Schema Variations
+
+Schemas can vary across multiple dimensions:
+
+| Dimension | Examples |
+|-----------|----------|
+| Philosophy | `spec-driven`, `tdd`, `prototype-first` |
+| Version | `v1`, `v2`, `v3` |
+| Language | `en`, `zh`, `es` |
+| Custom | `team-alpha`, `experimental` |
+
+### Schema Resolution (XDG Standard)
+
+Schemas follow the XDG Base Directory Specification with a 2-level resolution:
+
+```
+1. ${XDG_DATA_HOME}/openspec/schemas/<name>/schema.yaml   # Global user override
+2. <package>/schemas/<name>/schema.yaml                    # Built-in defaults
+```
+
+**Platform-specific paths:**
+- Unix/macOS: `~/.local/share/openspec/schemas/`
+- Windows: `%LOCALAPPDATA%/openspec/schemas/`
+- All platforms: `$XDG_DATA_HOME/openspec/schemas/` (when set)
+
+**Why XDG?**
+- Schemas are workflow definitions (data), not user preferences (config)
+- Built-ins baked into package, never auto-copied
+- Users customize by creating files in global data dir
+- Consistent with modern CLI tooling standards
+
+### Template Inheritance (2 Levels Max)
+
+Templates are co-located with schemas in a `templates/` subdirectory:
+
+```
+1. ${XDG_DATA_HOME}/openspec/schemas/<schema>/templates/<artifact>.md  # User override
+2. <package>/schemas/<schema>/templates/<artifact>.md                   # Built-in
+```
+
+**Rules:**
+- User overrides take precedence over package built-ins
+- A CLI command shows resolved paths (no guessing)
+- No inheritance between schemas (copy if you need to diverge)
+- Templates are always co-located with their schema
+
+**Why this matters:**
+- Avoids "where does this come from?" debugging
+- No implicit magic that works until it doesn't
+- Schema + templates form a cohesive unit
+
+---
+
+## Executive Summary
+
+This is an **artifact tracker with dependency awareness** that guides iterative development through a structured artifact pipeline. The core innovation is using the **filesystem as a database** - artifact completion is detected by file existence, making the system stateless and version-control friendly.
+
+The system answers:
+- "What artifacts exist for this change?"
+- "What could I create next?" (not "what must I create")
+- "What's blocking X?" (informational, not prescriptive)
+
+---
+
+## Core Components
+
+### 1. ArtifactGraph (Slice 1 - COMPLETE)
+
+The dependency graph engine with XDG-compliant schema resolution.
+
+| Responsibility | Approach |
+|----------------|----------|
+| Model artifacts as a DAG | Artifact with `requires: string[]` |
+| Track completion state | `Set<string>` for completed artifacts |
+| Calculate build order | Kahn's algorithm (topological sort) |
+| Find ready artifacts | Check if all dependencies are in `completed` set |
+| Resolve schemas | XDG global → package built-ins |
+
+**Key Data Structures (Zod-validated):**
+
+```typescript
+// Zod schemas define types + validation
+const ArtifactSchema = z.object({
+  id: z.string().min(1),
+  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([]),
+});
+
+const SchemaYamlSchema = z.object({
+  name: z.string().min(1),
+  version: z.number().int().positive(),
+  description: z.string().optional(),
+  artifacts: z.array(ArtifactSchema).min(1),
+});
+
+// Derived types
+type Artifact = z.infer<typeof ArtifactSchema>;
+type SchemaYaml = z.infer<typeof SchemaYamlSchema>;
+```
+
+**Key Methods:**
+- `resolveSchema(name)` - Load schema with XDG fallback
+- `ArtifactGraph.fromSchema(schema)` - Build graph from schema
+- `detectState(graph, changeDir)` - Scan filesystem for completion
+- `getNextArtifacts(graph, completed)` - Find artifacts ready to create
+- `getBuildOrder(graph)` - Topological sort of all artifacts
+- `getBlocked(graph, completed)` - Artifacts with unmet dependencies
+
+---
+
+### 2. Change Utilities (Slice 2)
+
+Simple utility functions for programmatic change creation. No class, no abstraction layer.
+
+| Responsibility | Approach |
+|----------------|----------|
+| Create changes | Create dirs under `openspec/changes/<name>/` with README |
+| Name validation | Enforce kebab-case naming |
+
+**Key Paths:**
+
+```
+openspec/changes/<name>/   → Change instances with artifacts (project-level)
+```
+
+**Key Functions** (`src/utils/change-utils.ts`):
+- `createChange(projectRoot, name, description?)` - Create new change directory + README
+- `validateChangeName(name)` - Validate kebab-case naming, returns `{ valid, error? }`
+
+**Note:** Existing CLI commands (`ListCommand`, `ChangeCommand`) already handle listing, path resolution, and existence checks. No need to extract that logic - it works fine as-is.
+
+---
+
+### 3. InstructionLoader (Slice 3)
+
+Template resolution and instruction enrichment.
+
+| Responsibility | Approach |
+|----------------|----------|
+| Resolve templates | XDG 2-level fallback (schema-specific → shared → built-in) |
+| Build dynamic context | Gather dependency status, change info |
+| Enrich templates | Inject context into base templates |
+| Generate status reports | Formatted markdown with progress |
+
+**Key Class - ChangeState:**
+
+```
+ChangeState {
+  changeName: string
+  changeDir: string
+  graph: ArtifactGraph
+  completed: Set<string>
+
+  // Methods
+  getNextSteps(): string[]
+  getStatus(artifactId): ArtifactStatus
+  isComplete(): boolean
+}
+```
+
+**Key Functions:**
+- `getTemplatePath(artifactId, schemaName?)` - Resolve with 2-level fallback
+- `getEnrichedInstructions(artifactId, projectRoot, changeName?)` - Main entry point
+- `getChangeStatus(projectRoot, changeName?)` - Formatted status report
+
+---
+
+### 4. CLI (Slice 4)
+
+User interface layer. **All commands are deterministic** - require explicit `--change` parameter.
+
+| Command | Function | Status |
+|---------|----------|--------|
+| `status --change <id>` | Show change progress (artifact graph) | **NEW** |
+| `next --change <id>` | Show artifacts ready to create | **NEW** |
+| `instructions <artifact> --change <id>` | Get enriched instructions for artifact | **NEW** |
+| `list` | List all changes | EXISTS (`openspec change list`) |
+| `new <name>` | Create change | **NEW** (uses `createChange()`) |
+| `init` | Initialize structure | EXISTS (`openspec init`) |
+| `templates --change <id>` | Show resolved template paths | **NEW** |
+
+**Note:** Commands that operate on a change require `--change`. Missing parameter → error with list of available changes. Agent infers the change from conversation and passes it explicitly.
+
+**Existing CLI commands** (not part of this slice):
+- `openspec change list` / `openspec change show <id>` / `openspec change validate <id>`
+- `openspec list --changes` / `openspec list --specs`
+- `openspec view` (dashboard)
+- `openspec init` / `openspec archive <change>`
+
+---
+
+### 5. Claude Commands
+
+Integration layer for Claude Code. **Operational commands only** - artifact creation via natural language.
+
+| Command | Purpose |
+|---------|---------|
+| `/status` | Show change progress |
+| `/next` | Show what's ready to create |
+| `/run [artifact]` | Execute a specific step (power users) |
+| `/list` | List all changes |
+| `/new <name>` | Create a new change |
+| `/init` | Initialize structure |
+
+**Artifact creation:** Users say "create the proposal" or "write the tests" in natural language. The agent:
+1. Infers change from conversation (confirms if uncertain)
+2. Infers artifact from request
+3. Calls CLI with explicit `--change` parameter
+4. Creates artifact following instructions
+
+This works for ANY artifact in ANY schema - no new slash commands needed when schemas change.
+
+**Note:** Legacy commands (`/openspec-proposal`, `/openspec-apply`, `/openspec-archive`) exist in the main project for backward compatibility but are separate from this architecture.

+```
+
+---
+
+## Key Design Patterns
+
+### 1. Filesystem as Database
+
+No SQLite, no JSON state files. The existence of `proposal.md` means proposal is complete.
+
+```
+// State detection is just file existence checking
+if (exists(artifactPath)) {
+  completed.add(artifactId)
+}
+```
+
+### 2. Deterministic CLI, Inferring Agent
+
+**CLI layer:** Always deterministic - requires explicit `--change` parameter.
+
+```
+openspec status --change add-auth     # explicit, works
+openspec status                        # error: "No change specified"
+```
+
+**Agent layer:** Infers from conversation, confirms if uncertain, passes explicit `--change`.
+
+This separation means:
+- CLI is pure, testable, no state to corrupt
+- Agent handles all "smartness"
+- No config.yaml tracking of "active change"
+
+### 3. XDG-Compliant Schema Resolution
+
+```
+${XDG_DATA_HOME}/openspec/schemas/<name>/schema.yaml   # User override
+    ↓ (not found)
+<package>/schemas/<name>/schema.yaml                    # Built-in
+    ↓ (not found)
+Error (schema not found)
+```
+
+### 4. Two-Level Template Fallback
+
+```
+${XDG_DATA_HOME}/openspec/schemas/<schema>/templates/<artifact>.md  # User override
+    ↓ (not found)
+<package>/schemas/<schema>/templates/<artifact>.md                   # Built-in
+    ↓ (not found)
+Error (no silent fallback to avoid confusion)
+```
+
+### 5. Glob Pattern Support
+
+`specs/*.md` allows multiple files to satisfy a single artifact:
+
+```
+if (artifact.generates.includes("*")) {
+  const parentDir = changeDir / patternParts[0]
+  if (exists(parentDir) && hasFiles(parentDir)) {
+    completed.add(artifactId)
+  }
+}
+```
+
+### 6. Stateless State Detection
+
+Every command re-scans the filesystem. No cached state to corrupt.
+
+---
+
+## Artifact Pipeline (Default Schema)
+
+The default `spec-driven` schema:
+
+```
+┌──────────┐
+│ proposal │  (no dependencies)
+└────┬─────┘
+     │
+     ▼
+┌──────────┐
+│  specs   │  (requires: proposal)
+└────┬─────┘
+     │
+     ├──────────────┐
+     ▼              ▼
+┌──────────┐   ┌──────────┐
+│  design  │   │          │
+│          │◄──┤ proposal │
+└────┬─────┘   └──────────┘
+     │         (requires: proposal, specs)
+     ▼
+┌──────────┐
+│  tasks   │  (requires: design)
+└──────────┘
+```
+
+Other schemas (TDD, prototype-first) would have different graphs.
+
+---
+
+## Implementation Order
+
+Structured as **vertical slices** - each slice is independently testable.
+
+---
+
+### Slice 1: "What's Ready?" (Core Query) ✅ COMPLETE
+
+**Delivers:** Types + Graph + State Detection + Schema Resolution
+
+**Implementation:** `src/core/artifact-graph/`
+- `types.ts` - Zod schemas and derived TypeScript types
+- `schema.ts` - YAML parsing with Zod validation
+- `graph.ts` - ArtifactGraph class with topological sort
+- `state.ts` - Filesystem-based state detection
+- `resolver.ts` - XDG-compliant schema resolution
+- `builtin-schemas.ts` - Package-bundled default schemas
+
+**Key decisions made:**
+- Zod for schema validation (consistent with project)
+- XDG for global schema overrides
+- `Set<string>` for completion state (immutable, functional)
+- `inProgress` and `failed` states deferred (require external tracking)
+
+---
+
+### Slice 2: "Change Creation Utilities"
+
+**Delivers:** Utility functions for programmatic change creation
+
+**Scope:**
+- `createChange(projectRoot, name, description?)` → creates directory + README
+- `validateChangeName(name)` → kebab-case pattern enforcement
+
+**Not in scope (already exists in CLI commands):**
+- `listChanges()` → exists in `ListCommand` and `ChangeCommand.getActiveChanges()`
+- `getChangePath()` → simple `path.join()` inline
+- `changeExists()` → simple `fs.access()` inline
+- `isInitialized()` → simple directory check inline
+
+**Why simplified:** Extracting existing CLI logic into a class would require similar refactoring of `SpecCommand` for consistency. The existing code works fine (~15 lines each). Only truly new functionality is `createChange()` + name validation.
+
+---
+
+### Slice 3: "Get Instructions" (Enrichment)
+
+**Delivers:** Template resolution + context injection
+
+**Testable behaviors:**
+- Template fallback: schema-specific → shared → built-in → error
+- Context injection: completed deps show ✓, missing show ✗
+- Output path shown correctly based on change directory
+
+---
+
+### Slice 4: "CLI + Integration"
+
+**Delivers:** New artifact graph commands (builds on existing CLI)
+
+**New commands:**
+- `status --change <id>` - Show artifact completion state
+- `next --change <id>` - Show ready-to-create artifacts
+- `instructions <artifact> --change <id>` - Get enriched template
+- `templates --change <id>` - Show resolved paths
+- `new <name>` - Create change (wrapper for `createChange()`)
+
+**Already exists (not in scope):**
+- `openspec change list/show/validate` - change management
+- `openspec list --changes/--specs` - listing
+- `openspec view` - dashboard
+- `openspec init` - initialization
+
+**Testable behaviors:**
+- Each new command produces expected output
+- Commands compose correctly (status → next → instructions flow)
+- Error handling for missing changes, invalid artifacts, etc.

+- `ChangeCommand.list/show/validate()` in `src/commands/change.ts`
+- `ListCommand.execute()` in `src/core/list.ts`
+- `ViewCommand.execute()` in `src/core/view.ts` - dashboard
+- `src/core/init.ts` - initialization
+- `src/core/archive.ts` - archiving
+
+**Key Principles:**
+- **Filesystem IS the database** - stateless, version-control friendly
+- **Dependencies are enablers** - show what's possible, don't force order
+- **Deterministic CLI, inferring agent** - CLI requires explicit `--change`, agent infers from context
+- **XDG-compliant paths** - schemas and templates use standard user data directories
+- **2-level inheritance** - user override → package built-in (no deeper)
+- **Schemas are versioned** - support variations by philosophy, version, language

+# OpenSpec Experimental Release Plan
+
+This document outlines the plan to release the experimental artifact workflow system for user testing.
+
+## Overview
+
+The goal is to allow users to test the new artifact-driven workflow system alongside the existing OpenSpec commands. This experimental system (`opsx`) provides a more granular, step-by-step approach to creating change artifacts.
+
+## Three Workflow Modes
+
+### 1. Old Workflow (Current Production)
+- **Commands**: `/openspec:proposal`, `/openspec:apply`, `/openspec:archive`
+- **Behavior**: Hardcoded slash commands that generate all artifacts in one command
+- **Status**: Production, unchanged
+
+### 2. New Artifact System - Batch Mode (Future)
+- **Commands**: Refactored `/openspec:proposal` using schemas
+- **Behavior**: Schema-driven but generates all artifacts at once (like legacy)
+- **Status**: Not in scope for this experimental release
+- **Note**: This is a future refactor to unify the old system with schemas
+
+### 3. New Artifact System - Granular Mode (Experimental)
+- **Commands**: `/opsx:new`, `/opsx:continue`
+- **Behavior**: One artifact at a time, dependency-driven, iterative
+- **Status**: Target for this experimental release
+
+---
+
+## Work Items
+
+### 1. Rename AWF to OPSX
+
+**Current State:**
+- Commands: `/awf:start`, `/awf:continue`
+- Files: `.claude/commands/awf/start.md`, `.claude/commands/awf/continue.md`
+
+**Target State:**
+- Commands: `/opsx:new`, `/opsx:continue`
+- Files: `.claude/commands/opsx/new.md`, `.claude/commands/opsx/continue.md`
+
+**Tasks:**
+- [x] Create `.claude/commands/opsx/` directory
+- [x] Rename `start.md` → `new.md` and update content
+- [x] Copy `continue.md` with updated references
+- [x] Update all references from "awf" to "opsx" in command content
+- [x] Update frontmatter (name, description) to use "opsx" naming
+- [x] Remove `.claude/commands/awf/` directory
+
+**CLI Commands:**
+The underlying CLI commands (`openspec status`, `openspec instructions`, etc.) remain unchanged. Only the slash command names change.
+
+---
+
+### 2. Remove WF Skill Files
+
+**Current State:**
+- `.claude/commands/wf/start.md` - References non-existent `openspec wf` commands
+- `.claude/commands/wf/continue.md` - References non-existent `openspec wf` commands
+
+**Target State:**
+- Directory and files removed
+
+**Tasks:**
+- [x] Delete `.claude/commands/wf/start.md`
+- [x] Delete `.claude/commands/wf/continue.md`
+- [x] Delete `.claude/commands/wf/` directory
+
+---
+
+### 3. Add Agent Skills for Experimental Workflow
+
+**Purpose:**
+Generate experimental workflow skills using the [Agent Skills](https://agentskills.io/specification) open standard.
+
+**Why Skills Instead of Slash Commands:**
+- **Cross-editor compatibility**: Skills work in Claude Code, Cursor, Windsurf, and other compatible editors automatically
+- **Simpler implementation**: Single directory (`.claude/skills/`) instead of 18+ editor-specific configurators
+- **Standard format**: Open standard with simple YAML frontmatter + markdown
+- **User invocation**: Users explicitly invoke skills when they want to use them
+
+**Behavior:**
+1. Create `.claude/skills/` directory if it doesn't exist
+2. Generate two skills using the Agent Skills specification:
+   - `openspec-new-change/SKILL.md` - Start a new change with artifact workflow
+   - `openspec-continue-change/SKILL.md` - Continue working on a change (create next artifact)
+3. Skills are added **alongside** existing `/openspec:*` commands (not replacing)
+
+**Supported Editors:**
+- Claude Code (native support)
+- Cursor (native support via Settings → Rules → Import Settings)
+- Windsurf (imports `.claude` configs)
+- Cline, Codex, and other Agent Skills-compatible editors
+
+**Tasks:**
+- [x] Create skill template content for `openspec-new-change` (based on current opsx:new)
+- [x] Create skill template content for `openspec-continue-change` (based on current opsx:continue)
+- [x] Add temporary `artifact-experimental-setup` command to CLI
+- [x] Implement skill file generation (YAML frontmatter + markdown body)
+- [x] Add success message with usage instructions
+
+**Note:** The `artifact-experimental-setup` command is temporary and will be merged into `openspec init` once the experimental workflow is promoted to stable.
+
+**Skill Format:**
+Each skill is a directory with a `SKILL.md` file:
+```
+.claude/skills/
+├── openspec-new-change/
+│   └── SKILL.md          # name, description, instructions
+├── openspec-continue-change/
+│   └── SKILL.md          # name, description, instructions
+└── openspec-apply-change/
+    └── SKILL.md          # name, description, instructions
+```
+
+**CLI Interface:**
+```bash
+openspec artifact-experimental-setup
+
+# Output:
+# 🧪 Experimental Artifact Workflow Skills Created
+#
+#   ✓ .claude/skills/openspec-new-change/SKILL.md
+#   ✓ .claude/skills/openspec-continue-change/SKILL.md
+#   ✓ .claude/skills/openspec-apply-change/SKILL.md
+#
+# 📖 Usage:
+#
+#   Skills work automatically in compatible editors:
+#   • Claude Code - Auto-detected, ready to use
+#   • Cursor - Enable in Settings → Rules → Import Settings
+#   • Windsurf - Auto-imports from .claude directory
+#
+#   Ask Claude naturally:
+#   • "I want to start a new OpenSpec change to add <feature>"
+#   • "Continue working on this change"
+#
+#   Claude will automatically use the appropriate skill.
+#
+# 💡 This is an experimental feature.
+#    Feedback welcome at: https://github.com/Fission-AI/OpenSpec/issues
+```
+
+**Implementation Notes:**
+- Simple file writing: Create directories and write templated `SKILL.md` files (no complex logic)
+- Use existing `FileSystemUtils.writeFile()` pattern like slash command configurators
+- Template structure: YAML frontmatter + markdown body
+- Keep existing `/opsx:*` slash commands for now (manual cleanup later)
+- Skills use invocation model (user explicitly asks Claude to use them)
+- Skill `description` field guides when Claude suggests using the skill
+- Each `SKILL.md` has required fields: `name` (matches directory) and `description`
+
+---
+
+### 4. Update `/opsx:new` Command Content
+
+**Current Behavior (awf:start):**
+1. Ask user what they want to build (if no input)
+2. Create change directory
+3. Show artifact status
+4. Show what's ready
+5. Get instructions for proposal
+6. STOP and wait
+
+**New Behavior (opsx:new):**
+Same flow but with updated naming:
+- References to "awf" → "opsx"
+- References to `/awf:continue` → `/opsx:continue`
+- Update frontmatter name/description
+
+**Tasks:**
+- [x] Update all "awf" references to "opsx"
+- [x] Update command references in prompt text
+- [x] Verify CLI commands still work (they use `openspec`, not `awf`)
+
+---
+
+### 5. Update `/opsx:continue` Command Content
+
+**Current Behavior (awf:continue):**
+1. Prompt for change selection (if not provided)
+2. Check current status
+3. Create ONE artifact based on what's ready
+4. Show progress and what's unlocked
+5. STOP
+
+**New Behavior (opsx:continue):**
+Same flow with updated naming.
+
+**Tasks:**
+- [x] Update all "awf" references to "opsx"
+- [x] Update command references in prompt text
+
+---
+
+### 6. End-to-End Testing
+
+**Objective:**
+Run through a complete workflow with Claude using the new skills to create a real feature, validating the entire flow works.
+
+**Test Scenario:**
+Use a real OpenSpec feature as the test case (dog-fooding).
+
+**Test Flow:**
+1. Run `openspec artifact-experimental-setup` to create skills
+2. Verify `.claude/skills/openspec-new-change/SKILL.md` created
+3. Verify `.claude/skills/openspec-continue-change/SKILL.md` created
+4. Verify `.claude/skills/openspec-apply-change/SKILL.md` created
+5. Ask Claude: "I want to start a new OpenSpec change to add feature X"
+6. Verify Claude invokes the `openspec-new-change` skill
+7. Verify change directory created at `openspec/changes/add-feature-x/`
+8. Verify proposal template shown
+9. Ask Claude: "Continue working on this change"
+10. Verify Claude invokes the `openspec-continue-change` skill
+11. Verify `proposal.md` created with content
+12. Ask Claude: "Continue" (create specs)
+13. Verify `specs/*.md` created
+14. Ask Claude: "Continue" (create design)
+15. Verify `design.md` created
+16. Ask Claude: "Continue" (create tasks)
+17. Verify `tasks.md` created
+18. Verify status shows 4/4 complete
+19. Implement the feature based on tasks
+20. Run `/openspec:archive` to archive the change
+

+
+---
+
+### 7. Documentation for Users
+
+**Create user-facing documentation explaining:**
+
+1. **What is the experimental workflow?**
+   - A new way to create OpenSpec changes step-by-step using Agent Skills
+   - One artifact at a time with dependency tracking
+   - More interactive and iterative than the batch approach
+   - Works across Claude Code, Cursor, Windsurf, and other compatible editors
+
+2. **How to set up experimental workflow**
+   ```bash
+   openspec artifact-experimental-setup
+   ```
+
+   Note: This is a temporary command that will be integrated into `openspec init` once promoted to stable.
+
+3. **Available skills**
+   - `openspec-new-change` - Start a new change with artifact workflow
+   - `openspec-continue-change` - Continue working (create next artifact)
+
+4. **How to use**
+   - **Claude Code**: Skills are auto-detected, just ask Claude naturally
+     - "I want to start a new OpenSpec change to add X"
+     - "Continue working on this change"
+   - **Cursor**: Enable in Settings → Rules → Import Settings
+   - **Windsurf**: Auto-imports `.claude` directory
+
+5. **Example workflow**
+   - Step-by-step walkthrough with natural language interactions
+   - Show how Claude invokes skills based on user requests
+
+6. **Feedback mechanism**
+   - GitHub issue template for feedback
+   - What to report (bugs, UX issues, suggestions)
+
+**Tasks:**
+- [ ] Create `docs/experimental-workflow.md` user guide
+- [ ] Add GitHub issue template for experimental feedback
+- [ ] Update README with mention of experimental features
+
+---
+
+## Dependency Graph
+
+```
+1. Remove WF skill files
+   └── (no dependencies)
+
+2. Rename AWF to OPSX
+   └── (no dependencies)
+
+3. Add Agent Skills
+   └── Depends on: Rename AWF to OPSX (uses opsx content as templates)
+
+4. Update opsx:new content
+   └── Depends on: Rename AWF to OPSX
+
+5. Update opsx:continue content
+   └── Depends on: Rename AWF to OPSX
+
+6. E2E Testing
+   └── Depends on: Add Agent Skills (tests the skills workflow)
+
+7. User Documentation
+   └── Depends on: E2E Testing (need to know final behavior)
+```
+
+---
+
+## Out of Scope
+
+The following are explicitly NOT part of this experimental release:
+
+1. **Batch mode refactor** - Making legacy `/openspec:proposal` use schemas
+2. **New schemas** - Only shipping with existing `spec-driven` and `tdd`
+3. **Schema customization UI** - No `openspec schema list` or similar
+4. **Multiple editor support in CLI** - Skills work cross-editor automatically via `.claude/skills/`
+5. **Replacing existing commands** - Skills are additive, not replacing `/openspec:*` or `/opsx:*`
+
+---
+
+## Success Criteria
+
+The experimental release is ready when:
+
+1. `openspec-new-change`, `openspec-continue-change`, and `openspec-apply-change` skills work end-to-end
+2. `openspec artifact-experimental-setup` creates skills in `.claude/skills/`
+3. Skills work in Claude Code and are compatible with Cursor/Windsurf
+4. At least one complete workflow has been tested manually
+5. User documentation exists explaining how to generate and use skills
+6. Feedback mechanism is in place
+7. WF skill files are removed
+8. No references to "awf" remain in user-facing content
+
+---
+
+## Open Questions
+
+1. **Schema selection** - Should `opsx:new` allow selecting a schema, or always use `spec-driven`?
+   - Current: Always uses `spec-driven` as default
+   - Consider: Add `--schema tdd` option or prompt
+
+2. **Namespace in CLI** - Should experimental CLI commands be namespaced?
+   - Current: `openspec status`, `openspec instructions` (no namespace)
+   - Alternative: `openspec opsx status` (explicit experimental namespace)
+   - Recommendation: Keep current, less typing for users
+
+3. **Deprecation path** - If opsx becomes the default, how do we migrate?
+   - Not needed for experimental release
+   - Document that command names may change
+
+---
+
+## Estimated Work Breakdown
+
+| Item | Complexity | Notes |
+|------|------------|-------|
+| Remove WF files | Trivial | Just delete 2 files + directory |
+| Rename AWF → OPSX | Low | File renames + content updates |
+| Add Agent Skills | **Low** | **Simple: 3-4 files, single output directory, standard format** |
+| Update opsx:new content | Low | Text replacements |
+| Update opsx:continue content | Low | Text replacements |
+| E2E Testing | Medium | Manual testing, documenting results |
+| User Documentation | Medium | New docs, issue template |
+
+**Key Improvement:** Switching to Agent Skills reduces complexity significantly:
+- **Before:** 20+ files (type definitions, 18+ editor configurators, editor selection UI)
+- **After:** 3-4 files (skill templates, simple CLI command)
+- **Cross-editor:** Works automatically in Claude Code, Cursor, Windsurf without extra code
+

+
+## User Feedback from E2E Testing
+
+### What Worked Well
+
+1. **Clear dependency graph** ⭐ HIGH PRIORITY - KEEP
+   - The status command showing blocked/unblocked artifacts was intuitive:
+     ```
+     [x] proposal
+     [ ] design
+     [-] tasks (blocked by: design, specs)
+     ```
+   - Users always knew what they could work on next
+   - **Relevance**: Core UX strength to preserve
+
+2. **Structured instructions output** ⭐ HIGH PRIORITY - KEEP
+   - `openspec instructions <artifact>` gave templates, output paths, and context in one call
+   - Very helpful for understanding what to create
+   - **Relevance**: Essential for agent-driven workflow
+
+3. **Simple scaffolding** ✅ WORKS WELL
+   - `openspec new change "name"` just worked - created directory structure without fuss
+   - **Relevance**: Good baseline, room for improvement (see pain points)
+
+---
+
+### Pain Points & Confusion
+
+1. **Redundant CLI calls** ⚠️ MEDIUM PRIORITY
+   - Users called both `status` AND `next` every time, but they overlap significantly
+   - `status` already shows what's blocked
+   - **Recommendation**: Consider merging or making `next` give actionable guidance beyond just listing names
+   - **Relevance**: Reduces friction in iterative workflow
+
+2. **Specs directory structure was ambiguous** 🔥 HIGH PRIORITY - FIX
+   - Instructions said: `Write to: .../specs/**/*.md`
+   - Users had to guess: `specs/spec.md`? `specs/game/spec.md`? `specs/tic-tac-toe/spec.md`?
+   - Users ended up doing manual `mkdir -p .../specs/tic-tac-toe` then writing `spec.md` inside
+   - **Recommendation**: CLI should scaffold this directory structure automatically
+   - **Relevance**: Critical agent UX - ambiguous paths cause workflow friction
+
+3. **Repetitive --change flag** ⚠️ MEDIUM PRIORITY
+   - Every command needed `--change "tic-tac-toe-game"`
+   - After 10+ calls, this felt verbose
+   - **Recommendation**: `openspec use "tic-tac-toe-game"` to set context, then subsequent commands assume that change
+   - **Relevance**: Quality of life improvement for iterative sessions
+
+4. **No validation feedback** 🔥 HIGH PRIORITY - ADD
+   - After writing each artifact, users just ran `status` hoping it would show `[x]`
+   - Questions raised:
+     - How did it know the artifact was "done"? File existence?
+     - What if spec format was wrong (e.g., wrong heading levels)?
+   - **Recommendation**: Add `openspec validate --change "name"` to check content quality
+   - **Relevance**: Critical for user confidence and catching errors early
+
+5. **Query-heavy, action-light CLI** 🔥 HIGH PRIORITY - ENHANCE
+   - Most commands retrieve info. The only "action" is `new change`
+   - Artifact creation is manual Write to guessed paths
+   - **Recommendation**: `openspec create proposal --change "name"` could scaffold the file with template pre-filled, then user just edits
+   - **Relevance**: Directly impacts agent productivity - reduce manual file writing
+
+6. **Instructions output was verbose** ⚠️ LOW PRIORITY
+   - XML-style output (`<artifact>`, `<template>`, `<instruction>`) was parseable but long
+   - Key info (output path, template) was buried in ~50 lines
+   - **Recommendation**: Add compact mode or structured JSON output for agents
+   - **Relevance**: Nice-to-have for agent parsing efficiency
+
+---
+
+### Workflow Friction
+
+1. **Mandatory "STOP and wait" after showing proposal template** ⚠️ MEDIUM PRIORITY
+   - The skill said "STOP and wait" after showing the proposal template
+   - This felt overly cautious when user had already provided enough context (e.g., "tic tac toe, single player vs AI, minimal aesthetics")
+   - **Recommendation**: Make the pause optional or conditional based on context clarity
+   - **Relevance**: Reduces unnecessary round-trips in agent conversations
+
+2. **No connection to implementation** 🔥 HIGH PRIORITY - ROADMAP ITEM
+   - After 4/4 artifacts complete, then what? The workflow ends at planning
+   - No `openspec apply` or guidance on how to execute the tasks
+   - User asked "would you like me to implement?" but that's outside OpenSpec's scope currently
+   - **Recommendation**: Add implementation bridge - either:
+     - `openspec apply` command to start execution phase
+     - Clear handoff to existing `/openspec:apply` workflow
+     - Documentation on next steps after planning completes
+   - **Relevance**: Critical missing piece - users expect end-to-end workflow
+

+---
+
+## Design Decisions (from E2E Testing Feedback)
+
+Based on dev testing and analysis of agent workflow friction, we identified three blockers for experimental release and made the following decisions.
+
+### Blockers Identified
+
+From the pain points in E2E testing, three issues are blocking the experimental release:
+
+1. **Specs directory ambiguity** - Agents don't know where to write spec files or how to name capabilities
+2. **CLI is query-heavy** - Most commands retrieve info, artifact creation is manual
+3. **Apply integration missing** - After 4/4 artifacts complete, no guidance on implementation phase
+
+### Decision 1: Capability Discovery in Proposal (RESOLVED)
+
+**Problem:** The specs artifact instruction says "Create one spec file per capability in `specs/<name>/spec.md`" but:
+- Agent doesn't know what `<name>` should be
+- Capability identification requires research (existing specs, codebase)
+- Proposal template asks for "Affected specs" but doesn't structure it
+- Research happens implicitly, output isn't captured
+
+**Decision:** Enrich the proposal template to explicitly capture capability discovery.
+
+**Current proposal template:**
+```markdown
+## Why
+## What Changes
+## Impact
+- Affected specs: List capabilities...  ← vague, easy to skip
+- Affected code: ...
+```
+
+**New proposal template:**
+```markdown
+## Why
+## What Changes
+## Capabilities
+
+### New Capabilities
+<!-- Capabilities being introduced (will create new specs/<name>/spec.md) -->
+- `<name>`: <brief description of what this capability covers>
+
+### Modified Capabilities
+<!-- Existing capabilities being changed (will update existing specs) -->
+- `<existing-name>`: <what's changing>
+
+## Impact
+<!-- Affected code, APIs, dependencies, systems -->
+```
+
+**Rationale:**
+- Proposal already asks for capabilities (just poorly) - this makes it explicit
+- Captured output is reviewable (vs implicit research that can't be verified)
+- Creates clear contract between proposal and specs phases
+- Distinguishes NEW vs MODIFIED upfront (critical for specs phase)
+- Agent can't skip research - it's part of the deliverable
+
+**Implementation:**
+- Update `schemas/spec-driven/templates/proposal.md`
+- Update proposal instruction in `schemas/spec-driven/schema.yaml`
+- Update skill instructions to guide capability discovery
+
+### Decision 2: CLI Action Commands (IN PROGRESS)
+
+**Problem:** CLI is mostly query-oriented. Agents run `openspec status`, `openspec next`, `openspec instructions` but then must manually write files.
+
+#### Decision 2a: Remove `openspec next` command (RESOLVED)
+
+**Problem:** The `next` command is redundant. It only shows which artifacts are ready, but `status` already shows this information (artifacts with status "ready" vs "blocked" vs "done").
+
+**Current behavior:**
+```bash
+openspec status --change "X"  # Shows: proposal (done), specs (ready), design (blocked), tasks (blocked)
+openspec next --change "X"    # Shows: ["specs"]  ← redundant
+```
+
+**Decision:** Remove the `next` command. Agents should use `status` which provides the same info plus more context.
+
+**Implementation:**
+- Remove `next` command from CLI
+- Update skill instructions to use `status` instead of `next`
+- Update AGENTS.md references
+
+#### Decision 2b: CLI Scaffolding (RESOLVED - NO)
+
+**Problem:** After getting instructions, agents manually write files. Should CLI scaffold artifacts instead?
+
+**Options considered:**
+- Add `openspec create <artifact>` commands that scaffold files with templates
+- Keep current approach where agent writes files directly from instructions
+- Hybrid: CLI can scaffold, agent can also write directly
+
+**Decision:** Keep current flow. No scaffolding commands.
+
+**Rationale (from agent ergonomics perspective):**
+- One Write is better than multiple Edits - agent composes full content atomically
+- `instructions` already provides template in context - scaffolding just moves it to a file
+- Fewer tool calls: `instructions` + Write (2) vs `create` + `instructions` + Read + Edit×N (4+)
+- Scaffolding doesn't solve the real problem (not knowing WHAT to write)
+- Real problem solved by proposal template change (capability discovery)
+
+**For multi-file artifacts (specs):** Scaffolding can't help because CLI doesn't know capability names until proposal is complete. The capability discovery in proposal solves this.
+
+### Decision 3: Apply Integration (RESOLVED)
+
+**Original problem:** After planning completes (4/4 artifacts), the experimental workflow ends. No guidance on implementation.
+
+**Key insight: No phases, just actions.**
+
+Through discussion, we realized phases (planning → implementation → archive) are an artificial constraint. Work is fluid:
+- You might start implementing, realize the design is wrong → update design.md
+- You're halfway through tasks, discover a new requirement → update specs
+- You bounce between "planning" and "implementing" constantly
+
+**The better model: Actions on a Change**
+
+A change is a thing (with artifacts). Actions are verbs you perform on a change. Actions aren't phases - they're fluid operations you can perform anytime.
+
+| Action | What it does | Skill | CLI Command |
+|--------|--------------|-------|-------------|
+| `new` | Create a change (scaffold directory) | `opsx:new` | `openspec new change` |
+| `continue` | Create next artifact (dependency-aware) | `opsx:continue` | `openspec instructions` |
+| `apply` | Implement tasks (execute, check off) | `opsx:apply` (NEW) | TBD |
+| `update` | Refresh/update artifacts based on learnings | `opsx:update` (NEW) | TBD |
+| `explore` | Research, ask questions, understand | `opsx:explore` (NEW) | TBD |
+| `validate` | Check artifacts are correct/complete | TBD | `openspec validate` |
+| `archive` | Finalize and move to archive | existing | `openspec archive` |
+
+**Key principles:**
+- Actions are modeled as skills (primary interface for agents)
+- Some skills have matching CLI commands for convenience
+- Skills and CLI commands are decoupled - not everything needs both
+- Actions can be performed in any order (with soft prerequisites)
+- No linear phase gates
+
+**What the schema defines:**
+- Artifacts (what they are, where they go)
+- Dependencies (what must exist first)
+- Required vs optional
+- Templates + instructions
+
+**What the schema does NOT define:**
+- Phases
+- When you can modify things
+- Linear workflow
+
+**Progress tracking:**
+- tasks.md checkboxes = implementation progress
+- Artifact existence = planning progress
+- Archive readiness = user decides (or all tasks done)
+
+**For experimental release:**
+- Create `opsx:apply` skill (guidance for implementing tasks)
+- Document the "actions on a change" model
+- Other actions (update, explore) can come later
+
+---
+
+### Design: `openspec-apply-change` Skill
+
+#### Overview
+
+The apply skill guides agents through implementing tasks from a completed (or in-progress) change. Unlike the old `/openspec:apply` command, this skill:
+- Is **fluid** - can be invoked anytime, not just after all artifacts are done
+- Allows **artifact updates** - if implementation reveals issues, update design/specs
+- Works **until done** - keeps going through tasks until complete or blocked
+- Tracks **progress via checkboxes** - tasks.md is the source of truth
+
+#### Skill Metadata
+
+```yaml
+name: openspec-apply-change
+description: Implement tasks from an OpenSpec change. Use when the user wants to start implementing, continue implementation, or work through tasks.
+```
+
+#### When to Invoke
+
+The skill should be invoked when:
+- User says "implement this change" or "start implementing"
+- User says "work on the tasks" or "do the next task"
+- User says "apply this change"
+- All artifacts are complete and user wants to proceed
+- User wants to continue implementation after a break
+
+#### Input
+
+- Optionally: change name
+- Optionally: specific task number to work on
+- If omitted: prompt for change selection (same pattern as continue-change)
+
+#### Steps
+
+```markdown
+**Steps**
+
+1. **If no change name provided, prompt for selection**
+
+   Run `openspec list --json` to get available changes. Use **AskUserQuestion** to let user select.
+
+   Show changes that have tasks.md (implementation-ready).
+   Mark changes with incomplete tasks as "(In Progress)".
+
+2. **Get apply instructions**
+
+   ```bash
+   openspec instructions apply --change "<name>" --json
+   ```
+
+   This returns:
+   - Context file paths (proposal, specs, design, tasks)
+   - Progress (total, complete, remaining)
+   - Task list with status
+   - Dynamic instruction based on current state
+
+   **Handle states:**
+   - If blocked (missing artifacts): show message, suggest `openspec-continue-change`
+   - If all done: congratulate, suggest archive
+   - Otherwise: proceed to implementation
+
+3. **Read context files**
+
+   Read the files listed in the instructions:
+   - `proposal.md` - why and what
+   - `specs/*.md` - requirements and scenarios
+   - `design.md` - technical approach (if exists)
+   - `tasks.md` - the implementation checklist
+
+4. **Show current progress**
+
+   Display:
+   - Progress: "N/M tasks complete"
+   - Remaining tasks overview
+   - Dynamic instruction from CLI
+
+5. **Implement tasks (loop until done or blocked)**
+
+   For each pending task:
+   - Show which task is being worked on
+   - Make the code changes required
+   - Keep changes minimal and focused
+   - Mark task complete in tasks.md: `- [ ]` → `- [x]`
+   - Continue to next task
+
+   **Pause if:**
+   - Task is unclear → ask for clarification
+   - Implementation reveals a design issue → suggest updating artifacts
+   - Error or blocker encountered → report and wait for guidance
+   - User interrupts
+
+6. **On completion or pause, show status**
+
+   Display:
+   - Tasks completed this session
+   - Overall progress: "N/M tasks complete"
+   - If all done: suggest archive
+   - If paused: explain why and wait for guidance
+```
+
+#### Output Format
+
+**During implementation:**
+```
+## Implementing: add-user-auth
+
+Working on task 3/7: Create UserAuth service class
+[...implementation happening...]
+✓ Task complete
+
+Working on task 4/7: Add login endpoint to AuthController
+[...implementation happening...]
+✓ Task complete
+
+Working on task 5/7: Add JWT token generation
+[...implementation happening...]
+```
+
+**On completion:**
+```
+## Implementation Complete
+
+**Change:** add-user-auth
+**Progress:** 7/7 tasks complete ✓
+
+### Completed This Session
+- [x] Create UserAuth service class
+- [x] Add login endpoint to AuthController
+- [x] Add JWT token generation
+- [x] Add logout endpoint
+- [x] Add auth middleware
+- [x] Write unit tests
+- [x] Update API documentation
+
+All tasks complete! Ready to archive this change.
+```
+
+**On pause (issue encountered):**
+```
+## Implementation Paused
+
+**Change:** add-user-auth
+**Progress:** 4/7 tasks complete
+
+### Issue Encountered
+Task 5 "Add JWT token generation" - the design specifies using RS256 but
+the existing auth library only supports HS256.
+
+**Options:**
+1. Update design.md to use HS256 instead
+2. Add a new JWT library that supports RS256
+3. Other approach
+
+What would you like to do?
+```
+
+#### Guardrails
+
+- Keep going through tasks until done or blocked
+- Always read context before starting (specs, design)
+- If task is ambiguous, pause and ask before implementing
+- If implementation reveals issues, pause and suggest artifact updates
+- Keep code changes minimal and scoped to each task
+- Update task checkbox immediately after completing each task
+- Pause on errors, blockers, or unclear requirements - don't guess
+
+#### Fluid Workflow Integration
+
+The apply skill supports the "actions on a change" model:
+
+**Can be invoked anytime:**
+- Before all artifacts are done (if tasks.md exists)
+- After partial implementation
+- Interleaved with other actions (update, continue)
+
+**Allows artifact updates:**
+- If implementation reveals design issues → suggest `opsx:update` or manual edit
+- If requirements need clarification → suggest updating specs
+- Not phase-locked - work fluidly
+
+**Example fluid workflow:**
+```
+User: "Implement add-user-auth"
+→ openspec-apply-change: implements tasks 1, 2, 3, 4...
+→ Pauses at task 5: "Design says RS256 but library only supports HS256"
+
+User: "Let's use HS256 instead, update the design"
+→ User edits design.md (or uses opsx:update in future)
+
+User: "Continue implementing"
+→ openspec-apply-change: implements tasks 5, 6, 7
+→ "All tasks complete! Ready to archive."
+```
+
+#### CLI Commands Used
+
+```bash
+openspec list --json                        # List changes for selection
+openspec status --change "<name>"           # Check artifact completion
+openspec instructions apply --change "<name>" # Get apply instructions (NEW)
+# File reads via Read tool for proposal, specs, design, tasks
+# File edits via Edit tool for checking off tasks
+```
+
+#### New CLI Command: `openspec instructions apply`
+
+For consistency with artifact instructions.
+
+**Usage:**
+```bash
+openspec instructions apply --change "<name>" [--json]
+```
+
+**Output (Markdown format):**
+```markdown
+## Apply: add-user-auth
+
+### Context Files
+- proposal: openspec/changes/add-user-auth/proposal.md
+- specs: openspec/changes/add-user-auth/specs/**/*.md
+- design: openspec/changes/add-user-auth/design.md
+- tasks: openspec/changes/add-user-auth/tasks.md
+
+### Progress
+2/7 complete
+
+### Tasks
+- [x] Create UserAuth service class
+- [x] Add login endpoint
+- [ ] Add JWT token generation
+- [ ] Add logout endpoint
+- [ ] Add auth middleware
+- [ ] Write unit tests
+- [ ] Update API documentation
+
+### Instruction
+Read context files, work through pending tasks, mark complete as you go.
+Pause if you hit blockers or need clarification.
+```
+
+**Benefits of CLI command:**
+- **Consistency** - same pattern as `openspec instructions <artifact>`
+- **Structured output** - progress, tasks, context paths in one call
+- **Clean format** - markdown is readable and compact (vs verbose XML)
+- **Extensibility** - can add more sections later if needed
+- **JSON option** - `--json` flag available for programmatic use
+
+#### Differences from Old `/openspec:apply`
+
+| Aspect | Old `/openspec:apply` | New `openspec-apply-change` |
+|--------|----------------------|----------------------------|
+| Invocation | After all artifacts done | Anytime (if tasks.md exists) |
+| Granularity | All tasks at once | All tasks, but pauses on issues |
+| Artifact updates | Not mentioned | Encouraged when needed |
+| Progress tracking | Update all at end | Update after each task |
+| Flow control | Push through everything | Pause on blockers, resume after |
+| Context loading | Read once at start | Read context, reference as needed |
+| Issue handling | Not specified | Pause, present options, wait for guidance |
+
+#### Implementation Notes
+
+1. **Add CLI command**: Add `openspec instructions apply` to artifact-workflow.ts
+   - Parse tasks.md for progress (count done/pending)
+   - Return context paths, progress, task list, simple instruction
+2. **Add to skill-templates.ts**: Create `getApplyChangeSkillTemplate()` function
+3. **Update artifact-experimental-setup**: Generate this skill alongside new/continue
+4. **Update skills list**: Add to `.claude/skills/` directory
+5. **Test the flow**: Verify it works with existing changes that have tasks.md
+

+# Experimental Workflow (OPSX)
+
+> **Status:** Experimental. Things might break. Feedback welcome on [Discord](https://discord.gg/BYjPaKbqMt).
+>
+> **Compatibility:** Claude Code only (for now)
+
+## What Is It?
+
+OPSX is a new way to work with OpenSpec changes. Instead of one big proposal, you build **artifacts** step-by-step:
+
+```
+proposal → specs → design → tasks → implementation → archive
+```
+
+Each artifact has dependencies. Can't write tasks until you have specs. Can't implement until you have tasks. The system tracks what's ready and what's blocked.
+
+## Setup
+
+```bash
+# 1. Make sure you have openspec installed and initialized
+openspec init
+
+# 2. Generate the experimental skills
+openspec artifact-experimental-setup
+```
+
+This creates skills in `.claude/skills/` that Claude Code auto-detects.
+
+## Commands
+
+| Command | What it does |
+|---------|--------------|
+| `/opsx:new` | Start a new change |
+| `/opsx:continue` | Create the next artifact |
+| `/opsx:ff` | Fast-forward (create all artifacts at once) |
+| `/opsx:apply` | Implement the tasks |
+| `/opsx:sync` | Sync delta specs to main specs |
+| `/opsx:archive` | Archive when done |
+
+## Usage
+
+### Start a new change
+```
+/opsx:new
+```
+You'll be asked what you want to build and which workflow schema to use.
+
+### Build artifacts step-by-step
+```
+/opsx:continue
+```
+Creates one artifact at a time. Good for reviewing each step.
+
+### Or fast-forward
+```
+/opsx:ff add-dark-mode
+```
+Creates all artifacts in one go. Good when you know what you want.
+
+### Implement
+```
+/opsx:apply
+```
+Works through tasks, checking them off as you go.
+
+### Sync specs and archive
+```
+/opsx:sync      # Update main specs with your delta specs
+/opsx:archive   # Move to archive when done
+```
+
+## What's Different?
+
+**Standard workflow** (`/openspec:proposal`):
+- One big proposal document
+- Linear phases: plan → implement → archive
+- All-or-nothing artifact creation
+
+**Experimental workflow** (`/opsx:*`):
+- Discrete artifacts with dependencies
+- Fluid actions (not phases) - update artifacts anytime
+- Step-by-step or fast-forward
+- Schema-driven (can customize the workflow)
+
+The key insight: work isn't linear. You implement, realize the design is wrong, update it, continue. OPSX supports this.
+
+## Schemas
+
+Schemas define what artifacts exist and their dependencies. Currently available:
+
+- **spec-driven** (default): proposal → specs → design → tasks
+- **tdd**: tests → implementation → docs
+
+Run `openspec schemas` to see available schemas.
+
+## Tips
+
+- Use `/opsx:ff` when you have a clear idea, `/opsx:continue` when exploring
+- Tasks track progress via checkboxes in `tasks.md`
+- Delta specs (in `specs/`) get synced to main specs with `/opsx:sync`
+- If you get stuck, the status command shows what's blocked: `openspec status --change "name"`
+

+# Schema Customization
+
+This document describes how users can customize OpenSpec schemas and templates, the current manual process, and the gap that needs to be addressed.
+
+---
+
+## Overview
+
+OpenSpec uses a 2-level schema resolution system following the XDG Base Directory Specification:
+
+1. **User override**: `${XDG_DATA_HOME}/openspec/schemas/<name>/`
+2. **Package built-in**: `<npm-package>/schemas/<name>/`
+
+When a schema is requested (e.g., `spec-driven`), the resolver checks the user directory first. If found, that entire schema directory is used. Otherwise, it falls back to the package's built-in schema.
+
+---
+
+## Current Manual Process
+
+To override the default `spec-driven` schema, a user must:
+
+### 1. Determine the correct directory path
+
+| Platform | Path |
+|----------|------|
+| macOS/Linux | `~/.local/share/openspec/schemas/` |
+| Windows | `%LOCALAPPDATA%\openspec\schemas\` |
+| All (if set) | `$XDG_DATA_HOME/openspec/schemas/` |
+
+### 2. Create the directory structure
+
+```bash
+# macOS/Linux example
+mkdir -p ~/.local/share/openspec/schemas/spec-driven/templates
+```
+
+### 3. Find and copy the default schema files
+
+The user must locate the installed npm package to copy the defaults:
+
+```bash
+# Find the package location (varies by install method)
+npm list -g openspec --parseable
+# or
+which openspec && readlink -f $(which openspec)
+
+# Copy files from the package's schemas/ directory
+cp <package-path>/schemas/spec-driven/schema.yaml ~/.local/share/openspec/schemas/spec-driven/
+cp <package-path>/schemas/spec-driven/templates/*.md ~/.local/share/openspec/schemas/spec-driven/templates/
+```
+
+### 4. Modify the copied files
+
+Edit `schema.yaml` to change the workflow structure:
+
+```yaml
+name: spec-driven
+version: 1
+description: My custom workflow
+artifacts:
+  - id: proposal
+    generates: proposal.md
+    description: Initial proposal
+    template: proposal.md
+    requires: []
+  # Add, remove, or modify artifacts...
+```
+
+Edit templates in `templates/` to customize the content guidance.
+
+### 5. Verify the override is active
+
+Currently there's no command to verify which schema is being used. Users must trust that the file exists in the right location.
+
+---
+
+## Gap Analysis
+
+The current process has several friction points:
+
+| Issue | Impact |
+|-------|--------|
+| **Path discovery** | Users must know XDG conventions and platform-specific paths |
+| **Package location** | Finding the npm package path varies by install method (global, local, pnpm, yarn, volta, etc.) |
+| **No scaffolding** | Users must manually create directories and copy files |
+| **No verification** | No way to confirm which schema is actually being resolved |
+| **No diffing** | When upgrading openspec, users can't see what changed in built-in templates |
+| **Full copy required** | Must copy entire schema even to change one template |
+
+### User Stories Not Currently Supported
+
+1. *"I want to add a `research` artifact before `proposal`"* — requires manual copy and edit
+2. *"I want to customize just the proposal template"* — must copy entire schema
+3. *"I want to see what the default schema looks like"* — must find package path
+4. *"I want to revert to defaults"* — must delete files and hope paths are correct
+5. *"I upgraded openspec, did the templates change?"* — no way to diff
+
+---
+
+## Proposed Solution: Schema Configurator
+
+A CLI command (or set of commands) that handles path resolution and file operations for users.
+
+### Option A: Single `openspec schema` command
+
+```bash
+# List available schemas (built-in and user overrides)
+openspec schema list
+
+# Show where a schema resolves from
+openspec schema which spec-driven
+# Output: /Users/me/.local/share/openspec/schemas/spec-driven/ (user override)
+# Output: /usr/local/lib/node_modules/openspec/schemas/spec-driven/ (built-in)
+
+# Copy a built-in schema to user directory for customization
+openspec schema copy spec-driven
+# Creates ~/.local/share/openspec/schemas/spec-driven/ with all files
+
+# Show diff between user override and built-in
+openspec schema diff spec-driven
+
+# Remove user override (revert to built-in)
+openspec schema reset spec-driven
+
+# Validate a schema
+openspec schema validate spec-driven
+```
+
+### Option B: Dedicated `openspec customize` command
+
+```bash
+# Interactive schema customization
+openspec customize
+# Prompts: Which schema? What do you want to change? etc.
+
+# Copy and open for editing
+openspec customize spec-driven
+# Copies to user dir, prints path, optionally opens in $EDITOR
+```
+
+### Option C: Init-time schema selection
+
+```bash
+# During project init, offer schema customization
+openspec init
+# ? Select a workflow schema:
+#   > spec-driven (default)
+#     tdd
+#     minimal
+#     custom (copy and edit)
+```
+
+### Recommended Approach
+
+**Option A** provides the most flexibility and follows Unix conventions (subcommands for discrete operations). Key commands in priority order:
+
+1. `openspec schema list` — see what's available
+2. `openspec schema which <name>` — debug resolution
+3. `openspec schema copy <name>` — scaffold customization
+4. `openspec schema diff <name>` — compare with built-in
+5. `openspec schema reset <name>` — revert to defaults
+
+---
+
+## Implementation Considerations
+
+### Path Resolution
+
+The resolver already exists in `src/core/artifact-graph/resolver.ts`:
+
+```typescript
+export function getPackageSchemasDir(): string { ... }
+export function getUserSchemasDir(): string { ... }
+export function getSchemaDir(name: string): string | null { ... }
+export function listSchemas(): string[] { ... }
+```
+
+New commands would leverage these existing functions.
+
+### File Operations
+
+- Copy should preserve file permissions
+- Copy should not overwrite existing user files without `--force`
+- Reset should prompt for confirmation
+
+### Template-Only Overrides
+
+A future enhancement could support overriding individual templates without copying the entire schema. This would require changes to the resolution logic:
+
+```
+Current: schema dir (user) OR schema dir (built-in)
+Future:  schema.yaml from user OR built-in
+         + each template from user OR built-in (independent fallback)
+```
+
+This adds complexity but enables the "I just want to change one template" use case.

+# Schema Workflow: End-to-End Analysis
+
+This document analyzes the complete user journey for working with schemas in OpenSpec, identifies gaps, and proposes a phased solution.
+
+---
+
+## Current State
+
+### What Exists
+
+| Component | Status |
+|-----------|--------|
+| Schema resolution (XDG) | 2-level: user override → package built-in |
+| Built-in schemas | `spec-driven`, `tdd` |
+| Artifact workflow commands | `status`, `next`, `instructions`, `templates` with `--schema` flag |
+| Change creation | `openspec new change <name>` — no schema binding |
+
+### What's Missing
+
+| Component | Status |
+|-----------|--------|
+| Schema bound to change | Not stored — must pass `--schema` every time |
+| Project-local schemas | Not supported — can't version control with repo |
+| Schema management CLI | None — manual path discovery required |
+| Project default schema | None — hardcoded to `spec-driven` |
+
+---
+
+## User Journey Analysis
+
+### Scenario 1: Using a Non-Default Schema
+
+**Goal:** User wants to use TDD workflow for a new feature.
+
+**Today's experience:**
+```bash
+openspec new change add-auth
+# Creates directory, no schema info stored
+
+openspec status --change add-auth
+# Shows spec-driven artifacts (WRONG - user wanted TDD)
+
+# User realizes mistake...
+openspec status --change add-auth --schema tdd
+# Correct, but must remember --schema every time
+
+# 6 months later...
+openspec status --change add-auth
+# Wrong again - nobody remembers this was TDD
+```
+
+**Problems:**
+- Schema is a runtime argument, not persisted
+- Easy to forget `--schema` and get wrong results
+- No record of intended schema for future reference
+
+---
+
+### Scenario 2: Customizing a Schema
+
+**Goal:** User wants to add a "research" artifact before "proposal".
+
+**Today's experience:**
+```bash
+# Step 1: Figure out where to put overrides
+# Must know XDG conventions:
+#   macOS/Linux: ~/.local/share/openspec/schemas/
+#   Windows: %LOCALAPPDATA%\openspec\schemas/
+
+# Step 2: Create directory structure
+mkdir -p ~/.local/share/openspec/schemas/my-workflow/templates
+
+# Step 3: Find the npm package to copy defaults
+npm list -g openspec --parseable
+# Output varies by package manager:
+#   npm: /usr/local/lib/node_modules/openspec
+#   pnpm: ~/.local/share/pnpm/global/5/node_modules/openspec
+#   volta: ~/.volta/tools/image/packages/openspec/...
+#   yarn: ~/.config/yarn/global/node_modules/openspec
+
+# Step 4: Copy files
+cp -r <package-path>/schemas/spec-driven/* \
+      ~/.local/share/openspec/schemas/my-workflow/
+
+# Step 5: Edit schema.yaml and templates
+# No way to verify override is active
+# No way to diff against original
+```
+
+**Problems:**
+- Must know XDG path conventions
+- Finding npm package path varies by install method
+- No tooling to scaffold or verify
+- No diff capability when upgrading openspec
+
+---
+
+### Scenario 3: Team Sharing Custom Workflow
+
+**Goal:** Team wants everyone to use the same custom schema.
+
+**Today's options:**
+1. Everyone manually sets up XDG override — error-prone, drift risk
+2. Document setup in README — still manual, easy to miss
+3. Publish separate npm package — overkill for most teams
+4. Check schema into repo — **not supported** (no project-local resolution)
+
+**Problems:**
+- No project-local schema resolution
+- Can't version control custom schemas with the codebase
+- No single source of truth for team workflow
+
+---
+
+## Gap Summary
+
+| Gap | Impact | Workaround |
+|-----|--------|------------|
+| Schema not bound to change | Wrong results, forgotten context | Remember to pass `--schema` |
+| No project-local schemas | Can't share via repo | Manual XDG setup per machine |
+| No schema management CLI | Manual path hunting | Know XDG + find npm package |
+| No project default schema | Must specify every time | Always pass `--schema` |
+| No init-time schema selection | Missed setup opportunity | Manual config |
+
+---
+

+```
+
+### config.yaml (Project Config)
+
+```yaml
+# openspec/config.yaml
+defaultSchema: spec-driven
+```
+
+Sets the project-wide default schema. Used when:
+- Creating new changes without `--schema`
+- Running commands on changes without `change.yaml`
+
+### change.yaml (Change Metadata)
+
+```yaml
+# openspec/changes/add-auth/change.yaml
+schema: tdd
+created: 2025-01-15T10:30:00Z
+description: Add user authentication system
+```
+
+Binds a specific schema to a change. Created automatically by `openspec new change`.
+
+### Schema Resolution Order
+
+```
+1. ./openspec/schemas/<name>/                    # Project-local
+2. ~/.local/share/openspec/schemas/<name>/       # User global (XDG)
+3. <npm-package>/schemas/<name>/                 # Built-in
+```
+
+Project-local takes priority, enabling version-controlled custom schemas.
+
+### Schema Selection Order (Per Command)
+
+```
+1. --schema CLI flag                    # Explicit override

+## Ideal User Experience
+
+### Creating a Change
+
+```bash
+# Uses project default (from config.yaml, or spec-driven)
+openspec new change add-auth
+# Creates openspec/changes/add-auth/change.yaml:
+#   schema: spec-driven
+#   created: 2025-01-15T10:30:00Z
+
+# Explicit schema for this change
+openspec new change add-auth --schema tdd
+# Creates change.yaml with schema: tdd
+```
+
+### Working with Changes
+
+```bash
+# Auto-reads schema from change.yaml — no --schema needed
+openspec status --change add-auth
+# Output: "Change: add-auth (schema: tdd)"
+# Shows which artifacts are ready/blocked/done
+
+# Explicit override still works (with informational message)
+openspec status --change add-auth --schema spec-driven
+# "Note: change.yaml specifies 'tdd', using 'spec-driven' per --schema flag"
+```
+
+### Customizing Schemas
+
+```bash
+# See what's available
+openspec schema list
+# Built-in:
+#   spec-driven    proposal → specs → design → tasks
+#   tdd            spec → tests → implementation → docs
+# Project: (none)
+# User: (none)
+
+# Copy to project for customization
+openspec schema copy spec-driven my-workflow
+# Created ./openspec/schemas/my-workflow/
+# Edit schema.yaml and templates/ to customize
+
+# Copy to global (user-level override)
+openspec schema copy spec-driven --global

+# or: ~/.local/share/openspec/schemas/spec-driven/ (user)
+# or: /usr/local/lib/node_modules/openspec/schemas/spec-driven/ (built-in)
+
+# Compare override with built-in
+openspec schema diff spec-driven
+# Shows diff between user/project version and package built-in
+
+# Remove override, revert to built-in
+openspec schema reset spec-driven
+# Removes ./openspec/schemas/spec-driven/ (or --global for user dir)
+```
+
+### Project Setup
+
+```bash

+#     tdd (spec → tests → implementation → docs)
+#     (custom schemas if detected)
+#
+# Writes to openspec/config.yaml:

+
+---
+
+## Implementation Phases
+
+### Phase 1: Change Metadata (change.yaml)
+
+**Priority:** High
+**Solves:** "Forgot --schema", lost context, wrong results
+
+**Scope:**
+- Create `change.yaml` when running `openspec new change`
+- Store `schema`, `created` timestamp
+- Modify workflow commands to read schema from `change.yaml`
+- `--schema` flag overrides (with informational message)
+- Backwards compatible: missing `change.yaml` → use default
+
+**change.yaml format:**
+```yaml
+schema: tdd
+created: 2025-01-15T10:30:00Z
+```
+
+**Migration:**
+- Existing changes without `change.yaml` continue to work
+- Default to `spec-driven` (current behavior)
+- Optional: `openspec migrate` to add `change.yaml` to existing changes
+
+---
+
+### Phase 2: Project-Local Schemas
+
+**Priority:** High
+**Solves:** Team sharing, version control, no XDG knowledge needed
+
+**Scope:**
+- Add `./openspec/schemas/` to resolution order (first priority)
+- `openspec schema copy <name> [new-name]` creates in project by default
+- `--global` flag for user-level XDG directory
+- Teams can commit `openspec/schemas/` to repo
+
+**Resolution order:**
+```
+1. ./openspec/schemas/<name>/           # Project-local (NEW)
+2. ~/.local/share/openspec/schemas/<name>/  # User global
+3. <npm-package>/schemas/<name>/        # Built-in
+```
+
+---
+
+### Phase 3: Schema Management CLI
+
+**Priority:** Medium
+**Solves:** Path discovery, scaffolding, debugging
+
+**Commands:**
+```bash
+openspec schema list              # Show available schemas with sources
+openspec schema which <name>      # Show resolution path
+openspec schema copy <name> [to]  # Copy for customization
+openspec schema diff <name>       # Compare with built-in
+openspec schema reset <name>      # Remove override
+openspec schema validate <name>   # Validate schema.yaml structure
+```
+
+---
+
+### Phase 4: Project Config + Init Enhancement
+
+**Priority:** Low
+**Solves:** Project-wide defaults, streamlined setup
+
+**Scope:**
+- Add `openspec/config.yaml` with `defaultSchema` field
+- `openspec init` prompts for schema selection
+- Store selection in `config.yaml`
+- Commands use as fallback when no `change.yaml` exists
+
+**config.yaml format:**
+```yaml
+defaultSchema: spec-driven
+```
+
+---
+
+## Backwards Compatibility
+
+| Scenario | Behavior |
+|----------|----------|
+| Existing change without `change.yaml` | Uses `--schema` flag or project default or `spec-driven` |
+| Existing project without `config.yaml` | Falls back to `spec-driven` |
+| `--schema` flag provided | Overrides `change.yaml` (with info message) |
+| No project-local schemas dir | Skipped in resolution, checks user/built-in |
+
+All existing functionality continues to work. New features are additive.

+# OpenSpec Parallel Delta Remediation Plan
+
+## Problem Summary
+- Active changes apply requirement-level replacements when archiving. When two changes touch the same requirement, the second archive overwrites the first and silently drops scenarios (e.g., Windsurf vs. Kilo Code slash command updates).
+- The archive workflow (`src/core/archive.ts:191` and `src/core/archive.ts:501`) rebuilds main specs by replacing entire requirement blocks with the content contained in the change delta. The delta format (`src/core/parsers/requirement-blocks.ts:113`) has no notion of base versions or scenario-level operations.
+- The tooling cannot detect divergence between the change author’s starting point and the live spec, so parallel development corrupts the source of truth without warning.
+
+## Observed Failure Mode
+- Change A (`add-windsurf-workflows`) adds a Windsurf scenario under `Slash Command Configuration`.
+- Change B (`add-kilocode-workflows`) adds a Kilo Code scenario to the same requirement, starting from the pre-Windsurf spec.
+- After Change A archives, the main spec contains both scenarios.
+- When Change B archives, `buildUpdatedSpec` sees a `MODIFIED` block for `Slash Command Configuration` and replaces the requirement with the four-scenario variant shipped in that change. Because that file never learned about Windsurf, the Windsurf scenario disappears.
+- There is no warning, diff, or conflict indicator—the archive completes successfully, and the source-of-truth spec now omits a shipped scenario.
+
+## Root Causes
+1. **Replace-only semantics.** `buildUpdatedSpec` performs hash-map substitution of requirement blocks and cannot merge or compare individual scenarios (`src/core/archive.ts:455`-`src/core/archive.ts:526`).
+2. **Missing base fingerprint.** Changes do not persist the requirement content they were authored against, so the archive step cannot tell if the live spec diverged.
+3. **Single-level granularity.** The delta language only understands requirements. Even if we introduced scenario-level parsing, we would still lose sibling edits without an accompanying merge strategy.
+4. **Lack of conflict UX.** The CLI never forces contributors to reconcile parallel updates. There is no equivalent of `git merge`, `git rebase`, or conflict markers.
+
+## Design Objectives
+- Preserve every approved scenario regardless of archive order.
+- Detect and block speculative archives when the live spec diverges from the author’s base.
+- Provide a deterministic, reviewable conflict resolution flow that mirrors source-control best practices.
+- Keep the authoring experience ergonomic: deltas should remain human-editable markdown.
+- Support incremental adoption so existing repositories can roll forward without breaking active work.
+
+## Proposed Fix: Layered Remediation
+
+### Phase 0 – Stop the Bleeding (Detection & Guardrails)
+1. **Persist requirement fingerprints alongside each change.**
+   - When scaffolding or validating a change, capture the current requirement body for every `MODIFIED`/`REMOVED`/`RENAMED` entry and write it to `changes/<id>/meta.json`.
+   - Store a stable hash (e.g., SHA-256) of the base requirement content and the raw text itself for later merges.
+2. **Validate fingerprints during archive.**
+   - Before `buildUpdatedSpec` mutates specs, recompute the requirement hash from the live spec.
+   - If the hash differs from the stored base, abort and instruct the user to rebase. This makes the destructive path impossible.
+3. **Surface intent in CLI output.**
+   - Show which requirements are stale, when they diverged, and which change last touched them.
+4. **Document interim manual mitigation.**
+   - Update `openspec/AGENTS.md` and docs so contributors know to rerun `openspec change sync` (see Phase 1) whenever another change lands.
+
+_Outcome:_ We prevent data loss immediately while we work on a richer merge story.
+
+### Phase 1 – Add a Rebase Workflow (Author-Side Merge)
+1. **Introduce `openspec change sync <id>` (or `rebase`).**
+   - Reads the stored base snapshot, the current spec, and the author’s delta.
+   - Performs a 3-way merge per requirement. A naive diff3 on markdown lines is acceptable initially because we already operate on requirement-sized chunks.
+   - If the merge is clean, rewrite the `MODIFIED` block with the merged text and refresh the stored fingerprint.
+   - On conflict, write conflict markers inside the change delta (similar to Git) and require the author to hand-edit before re-running validation.
+2. **Enrich validator messages.**
+   - `openspec validate` should flag unresolved conflict markers or fingerprint mismatches so errors appear early in the workflow.
+3. **Optional:** Offer a `--rewrite-scenarios` helper that merges bullet lists of scenarios to reduce manual editing noise.
+
+_Outcome:_ Contributors can safely reconcile their work with the latest spec before archiving, restoring true parallel development.
+
+### Phase 2 – Increase Delta Granularity
+1. **Extend the delta language with scenario-level directives.**
+   - Allow `## MODIFIED Requirements` + `## ADDED Scenarios` / `## MODIFIED Scenarios` sections nested under the requirement header.
+   - Backed by stable scenario identifiers (explicit IDs or generated hashes) stored in `meta.json`. This lets the system reason about individual scenarios.
+2. **Teach the parser to understand nested operations.**
+   - Update `parseDeltaSpec` to emit scenario-level operations in addition to requirement blocks.
+   - Update `buildUpdatedSpec` (or its replacement) to merge scenario lists, preserving order while inserting new entries in a deterministic fashion.
+3. **Automate migration.**
+   - Provide a one-time command that inspects each existing spec, injects scenario IDs, and rewrites in-flight change deltas into the richer format.
+4. **Continue to rely on the Phase 1 rebase flow for conflicts when two changes edit the same scenario body or description.**
+
+_Outcome:_ Most concurrent updates become commutative, drastically reducing the odds of human merges.
+
+### Phase 3 – Structured Spec Graph (Long-Term)
+1. **Define stable requirement IDs.**
+   - Embed `Requirement ID: <uuid>` markers in specs so renames and moves are trackable.
+   - This enables future features like cross-capability references and better diff visualizations.
+2. **Model spec edits as operations over an AST.**
+   - Build an intermediate representation (IR) for requirements/scenarios/metadata.
+   - Use operational transforms or CRDT-like techniques to guarantee merge associativity.
+3. **Integrate with Git directly.**
+   - Offer optional `openspec branch` scaffolding that aligns spec changes with Git branches, letting teams leverage Git’s conflict editor for the markdown IR.
+
+_Outcome:_ OpenSpec graduates from replace-based updates to a resilient, intent-preserving spec management platform.
+
+## Migration & Product Impacts
+- **Backfill metadata:** add hashes for all active changes and the current main specs during the initial rollout.
+- **CLI UX:** new commands (`change sync`, enhanced `archive`) require documentation, help text, and release notes.
+- **Docs & AGENTS updates:** reinforce the rebase workflow and explain conflict resolution to AI assistants.
+- **Testing:** introduce fixtures covering divergent requirement fingerprints and merge resolution logic.
+- **Telemetry (optional):** log fingerprint mismatches so we can see how often teams hit conflicts after the rollout.
+
+## Open Questions / Risks
+- How should we order scenarios when multiple changes insert at different points? (Consider optional `position` metadata or deterministic alphabetical fallbacks.)
+- What is the graceful failure mode if contributors delete the `meta.json` file? (CLI should recreate fingerprints on demand.)
+- Do we need to support offline authors who cannot easily re-run the sync command before archiving? (Potential `--accept-outdated` escape hatch for emergencies.)
+- How will archived historical changes be handled? We may need a migration script to embed fingerprints retroactively so re-validation succeeds.
+
+## Immediate Next Steps
+1. Prototype fingerprint capture during `openspec change validate` and block archive on mismatches.
+2. Ship `openspec change sync` with line-based diff3 merging and conflict markers.
+3. Update contributor docs and AI instructions to mandate running `sync` before archiving.
+4. Plan the scenario-level delta extension and migration path as a follow-up RFC.

+#### 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.

+# Change: Add View Dashboard Command
+
+## Why
+
+Users need a quick, at-a-glance overview of their OpenSpec project status without running multiple commands. Currently, users must run `openspec list --changes` and `openspec list --specs` separately to understand the project state. A unified dashboard view would improve developer experience and provide immediate insight into project progress.
+
+## What Changes
+
+### Added `openspec view` Command
+
+The new command provides an interactive dashboard displaying:
+- Summary metrics (total specs, requirements, changes, task progress)
+- Active changes with visual progress bars
+- Completed changes
+- Specifications with requirement counts
+
+### Specifications Affected
+
+- **cli-view** (NEW): Complete specification for the view dashboard command
+
+## Implementation Details
+
+### File Structure
+- Created `/src/core/view.ts` implementing the `ViewCommand` class
+- Registered command in `/src/cli/index.ts`
+- Reuses existing utilities from `task-progress.ts` and `MarkdownParser`
+
+### Visual Design
+- Uses Unicode box drawing characters for borders
+- Color coding: cyan for specs, yellow for active, green for completed
+- Progress bars using filled (█) and empty (░) blocks
+- Clean alignment with proper padding
+
+### Technical Approach
+- Async data fetching from changes and specs directories
+- Parallel processing of specs and changes
+- Error handling for missing or invalid data
+- Maintains consistency with existing list command output

+# CLI View Command - Changes
+
+## ADDED Requirements
+
+### Requirement: Dashboard Display
+
+The system SHALL provide a `view` command that displays a dashboard overview of specs and changes.
+
+#### Scenario: Basic dashboard display
+
+- **WHEN** user runs `openspec view`
+- **THEN** system displays a formatted dashboard with sections for summary, active changes, completed changes, and specifications
+
+#### Scenario: No OpenSpec directory
+
+- **WHEN** user runs `openspec view` in a directory without OpenSpec
+- **THEN** system displays error message "✗ No openspec directory found"
+
+### Requirement: Summary Section
+
+The dashboard SHALL display a summary section with key project metrics.
+
+#### Scenario: Complete summary display
+
+- **WHEN** dashboard is rendered with specs and changes
+- **THEN** system shows total number of specifications and requirements
+- **AND** shows number of active changes in progress
+- **AND** shows number of completed changes
+- **AND** shows overall task progress percentage
+
+#### Scenario: Empty project summary
+
+- **WHEN** no specs or changes exist
+- **THEN** summary shows zero counts for all metrics
+
+### Requirement: Active Changes Display
+
+The dashboard SHALL show active changes with visual progress indicators.
+
+#### Scenario: Active changes with progress bars
+
+- **WHEN** there are in-progress changes with tasks
+- **THEN** system displays each change with change name left-aligned
+- **AND** visual progress bar using Unicode characters
+- **AND** percentage completion on the right
+
+#### Scenario: No active changes
+
+- **WHEN** all changes are completed or no changes exist
+- **THEN** active changes section is omitted from display
+
+### Requirement: Completed Changes Display
+
+The dashboard SHALL list completed changes in a separate section.
+
+#### Scenario: Completed changes listing
+
+- **WHEN** there are completed changes (all tasks done)
+- **THEN** system shows them with checkmark indicators in a dedicated section
+
+#### Scenario: Mixed completion states
+
+- **WHEN** some changes are complete and others active
+- **THEN** system separates them into appropriate sections
+
+### Requirement: Specifications Display
+
+The dashboard SHALL display specifications sorted by requirement count.
+
+#### Scenario: Specs listing with counts
+
+- **WHEN** specifications exist in the project
+- **THEN** system shows specs sorted by requirement count (descending) with count labels
+
+#### Scenario: Specs with parsing errors
+
+- **WHEN** a spec file cannot be parsed
+- **THEN** system includes it with 0 requirement count
+
+### Requirement: Visual Formatting
+
+The dashboard SHALL use consistent visual formatting with colors and symbols.
+
+#### Scenario: Color coding
+
+- **WHEN** dashboard elements are displayed
+- **THEN** system uses cyan for specification items
+- **AND** yellow for active changes
+- **AND** green for completed items
+- **AND** dim gray for supplementary text
+
+#### Scenario: Progress bar rendering
+
+- **WHEN** displaying progress bars
+- **THEN** system uses filled blocks (█) for completed portions and light blocks (░) for remaining
+
+### Requirement: Error Handling
+
+The view command SHALL handle errors gracefully.
+
+#### Scenario: File system errors
+
+- **WHEN** file system operations fail
+- **THEN** system continues with available data and omits inaccessible items
+
+#### Scenario: Invalid data structures
+
+- **WHEN** specs or changes have invalid format
+- **THEN** system skips invalid items and continues rendering

+# Add AGENTS.md Standard Support To Init/Update
+
+## Summary
+- Teach `openspec init` to manage a root-level `AGENTS.md` file using the same marker system as `CLAUDE.md`.
+- Allow `openspec update` to refresh or scaffold that root `AGENTS.md` so AGENTS-compatible tools always receive current instructions.
+- Keep the existing `openspec/AGENTS.md` template as the canonical source while ensuring assistants that read `AGENTS.md` opt-in instructions get the latest guidance automatically.
+
+## Motivation
+The README now points teams to AGENTS.md-compatible assistants, but the CLI only manages `CLAUDE.md`. Projects must hand-roll a root `AGENTS.md` file to benefit from the standard, and updates will drift unless maintainers remember to copy content manually. Extending `init` and `update` closes that gap so OpenSpec actually delivers on the promise of first-class AGENTS support.
+
+## Proposal
+1. Extend the `openspec init` selection flow with an "AGENTS.md standard" option that creates or refreshes a root `AGENTS.md` file wrapped in OpenSpec markers, mirroring the existing CLAUDE integration.
+2. When generating the file, pull the managed content from the same template used in `openspec/AGENTS.md`, ensuring both locations stay in sync.
+3. Update `openspec update` so it always refreshes the root `AGENTS.md` (creating it if missing) alongside `openspec/AGENTS.md` and any other configured assistants.
+4. Document the new behavior in CLI specs and verify marker handling (no duplicates, preserve user content outside the block) with tests for both commands.
+
+## Out of Scope
+- Adding additional AGENTS-specific prompts or workflows beyond the shared instructions block.
+- Non-interactive flags or bulk configuration for multiple standards in one run.
+- Broader restructuring of how templates are stored or loaded.
+
+## Risks & Mitigations
+- **Risk:** Accidentally overwriting user-edited content surrounding the managed block.
+  - **Mitigation:** Reuse the existing marker-update helper shared with `CLAUDE.md`, and add tests that cover files containing custom text before and after the block.
+- **Risk:** Divergence between `openspec/AGENTS.md` and the root file.
+  - **Mitigation:** Source the root file content from the canonical template rather than duplicating strings inline.
+- **Risk:** Confusion about when the file is created.
+  - **Mitigation:** Log creation vs update, and ensure help text references the AGENTS option during `init`.

+## MODIFIED Requirements
+### Requirement: AI Tool Configuration
+The command SHALL configure AI coding assistants with OpenSpec instructions based on user selection.
+
+#### Scenario: Prompting for AI tool selection
+
+- **WHEN** run
+- **THEN** prompt user to select AI tools to configure:
+  - Claude Code (✅ OpenSpec custom slash commands available)
+  - Cursor (✅ OpenSpec custom slash commands available)
+  - AGENTS.md (works with Codex, Amp, Copilot, …)
+
+### Requirement: AI Tool Configuration Details
+The command SHALL properly configure selected AI tools with OpenSpec-specific instructions using a marker system.
+
+#### Scenario: Configuring Claude Code
+
+- **WHEN** Claude Code is selected
+- **THEN** create or update `CLAUDE.md` in the project root directory (not inside openspec/)
+
+#### Scenario: Configuring AGENTS standard
+
+- **WHEN** the AGENTS.md standard is selected
+- **THEN** create or update `AGENTS.md` in the project root directory (not inside openspec/)
+
+#### Scenario: Creating new CLAUDE.md
+
+- **WHEN** CLAUDE.md does not exist
+- **THEN** create new file with OpenSpec content wrapped in markers:
+```markdown
+<!-- OPENSPEC:START -->
+# OpenSpec Project
+
+This document provides instructions for AI coding assistants on how to use OpenSpec conventions for spec-driven development. Follow these rules precisely when working on OpenSpec-enabled projects.
+
+This project uses OpenSpec for spec-driven development. Specifications are the source of truth.
+
+See @openspec/AGENTS.md for detailed conventions and guidelines.
+<!-- OPENSPEC:END -->
+```
+
+#### Scenario: Creating new AGENTS.md
+
+- **WHEN** AGENTS.md does not exist in the project root
+- **THEN** create new file with OpenSpec content wrapped in markers using the same template as CLAUDE.md
+
+#### Scenario: Updating existing CLAUDE.md
+
+- **WHEN** CLAUDE.md already exists
+- **THEN** preserve all existing content
+- **AND** insert OpenSpec content at the beginning of the file using markers
+- **AND** ensure markers don't duplicate if they already exist
+
+#### Scenario: Updating existing AGENTS.md
+
+- **WHEN** AGENTS.md already exists in the project root
+- **THEN** preserve all existing content
+- **AND** ensure the OpenSpec-managed block at the beginning of the file is refreshed without duplicating markers
+
+#### Scenario: Managing content with markers
+
+- **WHEN** using the marker system
+- **THEN** use `<!-- OPENSPEC:START -->` to mark the beginning of managed content
+- **AND** use `<!-- OPENSPEC:END -->` to mark the end of managed content
+- **AND** allow OpenSpec to update its content without affecting user customizations
+- **AND** preserve all content outside the markers intact
+
+WHY use markers:
+- Users may have existing CLAUDE.md or AGENTS.md instructions they want to keep
+- OpenSpec can update its instructions in future versions
+- Clear boundary between OpenSpec-managed and user-managed content

+The update command SHALL update OpenSpec instruction files to the latest templates in a team-friendly manner.
+
+#### Scenario: Running update command
+
+- **WHEN** a user runs `openspec update`
+- **THEN** the command SHALL:
+  - Check if the `openspec` directory exists
+  - Replace `openspec/AGENTS.md` with the latest template (complete replacement)
+  - Create or refresh a root-level `AGENTS.md` file using the managed marker block (create if missing)
+  - Update **only existing** AI tool configuration files (e.g., CLAUDE.md)
+    - Check each registered AI tool configurator
+    - For each configurator, check if its file exists
+    - Update only files that already exist using their markers
+    - Preserve user content outside markers
+  - Display success message listing updated files
+
+### Requirement: Tool-Agnostic Updates
+The update command SHALL handle file updates in a predictable and safe manner while respecting team tool choices.
+
+#### Scenario: Updating files
+
+- **WHEN** updating files
+- **THEN** completely replace `openspec/AGENTS.md` with the latest template
+- **AND** create or update the root-level `AGENTS.md` using the OpenSpec markers
+- **AND** update only the OpenSpec-managed blocks in **existing** AI tool files using markers
+- **AND** use the default directory name `openspec`
+- **AND** be idempotent (repeated runs have no additional effect)
+- **AND** respect team members' AI tool choices by not creating additional tool files beyond the root `AGENTS.md`
+
+### Requirement: Core Files Always Updated
+The update command SHALL always update the core OpenSpec files and display an ASCII-safe success message.
+
+#### Scenario: Successful update
+
+- **WHEN** the update completes successfully
+- **THEN** replace `openspec/AGENTS.md` with the latest template
+- **AND** ensure the root-level `AGENTS.md` matches the latest template via the marker block
+- **AND** update existing AI tool configuration files within markers

+# Allow Additional AI Tool Initialization After Setup
+
+## Summary
+- Let `openspec init` configure new AI coding tools for projects that already contain an OpenSpec structure.
+- Keep the initialization flow safe by skipping structure creation and only generating files for tools the user explicitly selects.
+- Provide clear feedback so users know which tool files were added versus already present.
+
+## Motivation
+Today `openspec init` exits with an error once an `openspec/` directory exists. That protects the directory layout, but it blocks
+teams that start with one assistant (for example, Claude Code) and later want to add another such as Cursor. They have to create
+those files by hand or rerun `init` in a clean clone, which undermines the "easy onboarding" promise. Letting the command extend
+an existing installation keeps the workflow consistent and avoids manual file management.
+
+## Proposal
+1. Detect an existing OpenSpec structure at the start of `openspec init` and branch into an "extend" mode instead of exiting.
+   - Announce that the base structure already exists and that the command will only manage AI tool configuration files.
+   - Keep the existing guard for directories or files we must not overwrite.
+2. Present the usual AI tool selection prompt even in extend mode, showing which tools are already configured.
+   - Skip disabled options that remain "coming soon".
+   - Mark already configured tools as such so users know whether selecting them will refresh or add files.
+3. When the user selects additional tools, generate the same initialization files that a fresh run would create (e.g., Cursor
+   workspace files) while leaving untouched tools intact apart from marker-managed sections.
+   - Do nothing when the user selects no new tools and keep the previous error messaging to avoid silently succeeding.
+4. Summarize the outcome (created, refreshed, skipped) before exiting with code 0 when work was performed.
+   - Include friendly guidance that future updates to shared content still come from `openspec update`.
+
+## Out of Scope
+- Changing how `openspec update` discovers or updates AI tool files.
+- Supporting brand-new AI tools beyond those already wired into the CLI.
+- Adding non-interactive flags for selecting multiple tools in one run (follow-up if needed).
+
+## Risks & Mitigations
+- **User confusion about extend mode** → Explicitly log what will happen before prompting and summarise results afterward.
+- **Accidental overwrites** → Continue using marker-based updates and skip files unless the user chooses that tool.
+- **Inconsistent state if init fails mid-run** → Reuse existing rollback/transaction logic so partial writes clean up.

+## MODIFIED Requirements
+### Requirement: Safety Checks
+The command SHALL perform safety checks to prevent overwriting existing structures and ensure proper permissions.
+
+#### Scenario: Detecting existing initialization
+- **WHEN** the `openspec/` directory already exists
+- **THEN** inform the user that OpenSpec is already initialized, skip recreating the base structure, and enter an extend mode
+- **AND** continue to the AI tool selection step so additional tools can be configured
+- **AND** display the existing-initialization error message only when the user declines to add any AI tools
+

+The command SHALL provide an interactive menu for AI tool selection with clear navigation instructions.
+
+#### Scenario: Displaying interactive menu
+- **WHEN** run in fresh or extend mode
+- **THEN** present a looping select menu that lets users toggle tools with Enter and finish via a "Done" option

+### Requirement: Additional AI Tool Initialization
+`openspec init` SHALL allow users to add configuration files for new AI coding assistants after the initial setup.
+
+#### Scenario: Configuring an extra tool after initial setup
+- **GIVEN** an `openspec/` directory already exists and at least one AI tool file is present
+- **WHEN** the user runs `openspec init` and selects a different supported AI tool
+- **THEN** generate that tool's configuration files with OpenSpec markers the same way as during first-time initialization
+- **AND** leave existing tool configuration files unchanged except for managed sections that need refreshing
+- **AND** exit with code 0 and display a success summary highlighting the newly added tool files
+
+### Requirement: Success Output Enhancements
+`openspec init` SHALL summarize tool actions when initialization or extend mode completes.
+
+#### Scenario: Showing tool summary
+- **WHEN** the command completes successfully
+- **THEN** display a categorized summary of tools that were created, refreshed, or skipped (including already-configured skips)
+- **AND** personalize the "Next steps" header using the names of the selected tools, defaulting to a generic label when none remain
+
+### Requirement: Exit Code Adjustments
+`openspec init` SHALL treat extend mode with no selected tools as a guarded error.
+
+#### Scenario: Preventing empty extend runs
+- **WHEN** OpenSpec is already initialized and the user selects no additional tools
+- **THEN** exit with code 1 after showing the existing-initialization guidance message

+# Add Slash Command Support for Coding Agents
+
+## Summary
+- Enable OpenSpec to generate and update custom slash commands for supported coding agents (Claude Code and Cursor).
+- Provide three slash commands aligned with OpenSpec's workflow: proposal (start a change proposal), apply (implement), and archive.
+- Share slash command templating between agents to make future extensions simple.
+
+## Motivation
+Developers use different coding agents and editors. Having consistent slash commands across tools for the OpenSpec workflow reduces friction and ensures a standard way to trigger the workflow. Supporting both Claude Code and Cursor now lays a foundation for future agents that introduce slash command features.
+
+## Proposal
+1. During `openspec init`, when a user selects a supported tool, generate slash command configuration for three OpenSpec workflow stages:
+   - Claude (namespaced): `/openspec/proposal`, `/openspec/apply`, `/openspec/archive`.
+   - Cursor (flat, prefixed): `/openspec-proposal`, `/openspec-apply`, `/openspec-archive`.
+   - Semantics:
+     - Create – scaffold a change (ID, `proposal.md`, `tasks.md`, delta specs); validate strictly.
+     - Apply – implement an approved change; complete tasks; validate strictly.
+     - Archive – archive after deployment; update specs if needed.
+   - Each command file MUST embed concise, step-by-step instructions sourced from `openspec/README.md` (see Template Content section).
+2. Store slash command files per tool:
+   - Claude Code: `.claude/commands/openspec/{proposal,apply,archive}.md`
+   - Cursor: `.cursor/commands/{openspec-proposal,openspec-apply,openspec-archive}.md`
+   - Ensure nested directories are created.
+3. Command file format and metadata:
+   - Use Markdown with optional YAML frontmatter for tool metadata (name/title, description, category/tags) when supported by the tool.
+   - Place OpenSpec markers around the body only, never inside frontmatter.
+   - Keep the visible slash name, file name, and any frontmatter `name`/`id` consistently aligned (e.g., `proposal`, `openspec-proposal`).
+   - Namespacing: categorize these under “OpenSpec” and prefer unique IDs (e.g., `openspec-proposal`) to avoid collisions.
+4. Centralize templates: define command bodies once and reuse across tools; apply minimal per-tool wrappers (frontmatter, categories, filenames).
+5. During `openspec update`, refresh only existing slash command files (per-file basis) within markers; do not create missing files or new tools.
+
+## Design Ideas
+- Introduce `SlashCommandConfigurator` to manage multiple files per tool.
+  - Expose targets rather than a single `configFileName` (e.g., `getTargets(): Array<{ path: string; kind: 'slash'; id: string }>`).
+  - Provide `generateAll(projectPath, openspecDir)` for init and `updateExisting(projectPath, openspecDir)` for update.
+- Per-tool adapters add only frontmatter and pathing; bodies come from shared templates.
+- Templates live in `TemplateManager` with helpers that extract concise, authoritative snippets from `openspec/README.md`.
+- Update flow logs per-file results so users see exactly which slash files were refreshed.
+
+### Marker Placement
+- Markers MUST wrap only the Markdown body contents:
+  - Frontmatter (if present) goes first.
+  - Then `<!-- OPENSPEC:START -->` … body … `<!-- OPENSPEC:END -->`.
+  - Avoid inserting markers into the YAML block to prevent parse errors.
+
+### Idempotency and Creation Rules
+- `init`: create all three files for the chosen tool(s) once; subsequent `init` runs are no-ops for existing files.
+- `update`: refresh only files that exist; skip missing ones without creating new files.
+- Directory creation for `.claude/commands/openspec/` and `.cursor/commands/` is the configurator’s responsibility.
+
+### Command Naming & UX
+- Claude Code: use namespacing in the slash itself for readability and grouping: `/openspec/proposal`, `/openspec/apply`, `/openspec/archive`.
+- Cursor: use flat names with an `openspec-` prefix: `/openspec-proposal`, `/openspec-apply`, `/openspec-archive`. Group via `category: OpenSpec` when supported.
+- Consistency: align file names, visible slash names, and any frontmatter `id` (e.g., `id: openspec-apply`).
+- Migration: do not rename existing commands during `update`; apply new naming only on `init` (or via an explicit migrate step).
+
+## Open Questions
+- Validate exact metadata/frontmatter supported by each tool version; if unsupported, omit frontmatter and ship Markdown body only.
+- Confirm the final Cursor command file location for the targeted versions; fall back to Markdown-only if Cursor does not parse frontmatter.
+- Evaluate additional commands beyond the initial three (e.g., `/show-change`, `/validate-all`) based on user demand.
+
+## Alternatives
+- Hard-code slash command text per tool (rejected: duplicates content; increases maintenance).
+- Delay Cursor support until its config stabilizes (partial accept): gate Cursor behind a feature flag until verified in real environments.
+
+## Risks
+- Tool configuration formats may change, requiring updates to wrappers/frontmatter.
+- Incorrect paths or categories can hide commands; add path existence checks and clear logging.
+- Marker misuse (inside frontmatter) can break parsing; enforce placement rules in tests.
+
+## Future Work
+- Support additional editors/agents that expose slash command APIs.
+- Allow users to customize command names and categories during `openspec init`.
+- Provide a dedicated command to regenerate slash commands without running full `update`.
+
+## File Format Examples
+The following examples illustrate expected structure. If a tool does not support frontmatter, omit the YAML block and keep only the markers + body.
+
+### Claude Code: `.claude/commands/openspec/proposal.md`
+```markdown
+---
+name: OpenSpec: Proposal
+description: Scaffold a new OpenSpec change and validate strictly.
+category: OpenSpec
+tags: [openspec, change]
+---
+<!-- OPENSPEC:START -->
+...command body from shared template...
+<!-- OPENSPEC:END -->
+```
+
+Slash invocation: `/openspec/proposal` (namespaced)
+
+### Cursor: `.cursor/commands/openspec-proposal.md`
+```markdown
+---
+name: /openspec-proposal
+id: openspec-proposal
+category: OpenSpec
+description: Scaffold a new OpenSpec change and validate strictly.
+---
+<!-- OPENSPEC:START -->
+...command body from shared template...
+<!-- OPENSPEC:END -->
+```
+
+Slash invocation: `/openspec-proposal` (flat, prefixed)
+
+## Template Content
+Templates should be brief, actionable, and sourced from `openspec/README.md` to avoid duplication. Each command body includes:
+- Guardrails: ask 1–2 clarifying questions if needed; follow minimal-complexity rules; use `pnpm` for Node projects.
+- Step list tailored to the workflow stage (proposal, apply, archive), including strict validation commands.
+- Pointers to `openspec show`, `openspec list`, and troubleshooting tips when validation fails.
+
+## Testing Strategy
+- Golden snapshots for generated files per tool (frontmatter + markers + body).
+- Partial presence tests: if 1–2 files exist, `update` only refreshes those and does not create missing ones.

+## Why
+Recent cross-shell regressions for `openspec` commands revealed that our existing unit/integration tests do not exercise the packaged CLI or shell-specific behavior. The prior attempt at Vitest spawn tests stalled because it coupled e2e coverage with `pnpm pack` installs, which fail in network-restricted environments. With those findings incorporated, we now need an approved plan to realign the work.
+
+## What Changes
+- Adopt a phased strategy that first stabilizes direct spawn testing of the built CLI (`node dist/cli/index.js`) using lightweight fixtures and a shared `runCLI` helper.
+- Expand coverage once the spawn harness is stable, keeping the initial matrix focused on bash jobs for Linux/macOS and `pwsh` on Windows while exercising both the direct `node dist/cli/index.js` invocation and the bin shim with non-TTY defaults and captured diagnostics.
+- Treat packaging/install validation as an optional CI safeguard: when a runner has registry access, run a simple pnpm-based pack→install→smoke-test flow; otherwise document it as out of scope while closing remaining hardening items.
+- Close out the remaining cross-shell hardening items: ensure `.gitattributes` covers packaged assets, enforce executable bits for CLI shims during CI, and finish the pending SIGINT handling improvements.
+
+## Impact
+- Tests: add `test/cli-e2e` spawn suite, create the shared `runCLI` helper, and adjust `vitest.setup.ts` as needed.
+- Tooling: update GitHub Actions workflows with the lightweight matrix above and (optionally) a packaging install check where network is available.
+- Docs: note phase progress and any limitations inline in this proposal (or the relevant spec) so future phases have clear context.
+
+### Phase 1 Status
+- Shared `test/helpers/run-cli.ts` guarantees the CLI bundle exists before spawning and enforces non-TTY defaults for every invocation.
+- New `test/cli-e2e/basic.test.ts` covers `--help`, `--version`, a successful `validate --all --json`, and an unknown-item error path against the `tmp-init` fixture copy.
+- Legacy top-level `validate` exec tests now rely on `runCLI`, avoiding manual `execSync` usage while keeping their fixture authoring intact.
+- CI matrix groundwork is in place (bash on Linux/macOS, pwsh on Windows) so the spawn suite runs the same way the helper does across supported shells.

+## 1. Phase 1 – Stabilize Local Spawn Coverage
+- [x] 1.1 Add `test/helpers/run-cli.ts` that ensures the build runs once and executes `node dist/cli/index.js` with non-TTY defaults; update `vitest.setup.ts` to reuse the shared build step.
+- [x] 1.2 Seed `test/cli-e2e` using the minimal fixture set (`tmp-init` or copy) to cover help/version, a happy-path `validate`, and a representative error flow via the new helper.

+## Why
+The current `openspec init` flow assumes a single assistant selection and stops once an OpenSpec structure already exists.

+# Change: Sort Active Changes by Progress
+
+## Problem
+- The dashboard currently lists active changes in filesystem discovery order.
+- Users cannot quickly spot proposals that have not started or are nearly complete.
+- Inconsistent ordering between runs makes it harder to track progress when many changes exist.
+
+## Proposal
+1. Update the Active Changes list in the dashboard to sort by percentage of completion in ascending order so 0% items show first.
+2. When two changes share the same completion percentage, break ties deterministically by change identifier (alphabetical).
+
+## Benefits
+- Highlights work that has not started yet, enabling quicker prioritization.
+- Provides consistent ordering across machines and repeated runs.
+- Keeps the dashboard compact while communicating the most important status signal.
+
+## Risks & Mitigations
+- **Risk:** Sorting logic could regress rendering when progress data is missing.
+  - **Mitigation:** Treat missing progress as 0% so items still surface and document behavior in tests.
+- **Risk:** Additional sorting could impact performance for large change sets.
+  - **Mitigation:** The number of active changes is typically small; sorting a few entries is negligible.
+
+## Success Criteria

+# Update Markdown Parser CRLF Handling
+
+## Problem
+Windows users report that `openspec validate` raises “Change must have a Why section” even when the section exists (see GitHub issue #77). The CLI currently splits markdown on `\n` and compares headers without stripping `\r`, so files saved with CRLF line endings keep a trailing carriage return in the header token. As a result the parser fails to detect `## Why`/`## What Changes`, triggering false validation errors and breaking the workflow on Windows-default editors.
+
+## Solution
+- Normalize markdown content inside the parser so CRLF and lone-CR inputs are treated as `\n` before section detection, trimming any carriage returns from titles and content comparisons.
+- Reuse the normalized reader everywhere `MarkdownParser` is constructed to keep behavior consistent for validation, view, spec, and list flows.
+- Add regression coverage that reproduces the failure (unit test around `parseChange` and a CLI spawn/e2e test that writes a CRLF change then runs `openspec validate`).
+- Update the `cli-validate` spec to codify the expectation that required sections are recognized regardless of line-ending style.
+
+## Benefits
+- Restores correct validation behavior for Windows editors without requiring manual line-ending conversion.
+- Locks in the fix with targeted tests so future parser refactors keep cross-platform support.
+- Clarifies the spec so downstream work (e.g., cross-shell e2e plan) understands the non-negotiable behavior.
+
+## Risks
+- Low: parser normalization touches shared code paths that parse specs and changes; need to ensure no regressions in other command consumers (mitigated by existing parser tests plus the new CRLF fixtures).

+## Why
+- Codex (the VS Code extension formerly known as Codeium Chat) exposes "slash commands" by reading Markdown prompt files from `~/.codex/prompts/`. Each file name becomes the `/command` users can run, with YAML frontmatter for metadata (`description`, `argument-hint`) and `$ARGUMENTS` to capture user input. The workflow screenshot shared by Kevin Kern ("Codex problem analyzer") shows the format OpenSpec should target so teams can invoke curated workflows straight from the chat palette.
+- Teams already rely on OpenSpec to manage the slash-command surface area for Claude, Cursor, OpenCode, Kilo Code, and Windsurf. Leaving Codex out forces them to manually copy/paste OpenSpec guardrails into `~/.codex/prompts/*.md`, which drifts quickly and undermines the "single source of truth" promise of the CLI.
+- Codex commands live outside the repository (under the user's home directory), so shipping an automated configurator that both scaffolds the prompts and keeps them refreshed via `openspec update` eliminates error-prone manual steps and keeps OpenSpec instructions synchronized across assistants.
+
+## What Changes
+- Add Codex to the `openspec init` tool picker with the same "already configured" detection we use for other editors, wiring an implementation that writes managed Markdown prompts directly to Codex's global directory (`~/.codex/prompts` or `$CODEX_HOME/prompts`) with OpenSpec marker blocks.
+- Produce three Codex prompt files—`openspec-proposal.md`, `openspec-apply.md`, and `openspec-archive.md`—whose content mirrors the shared slash-command templates while using YAML frontmatter (`description` and `argument-hint` fields) and `$ARGUMENTS` to capture all arguments as a single string (matching the GitHub Copilot pattern and official Codex specification).
+- Document Codex's global-only discovery and that OpenSpec writes prompts directly to `~/.codex/prompts` (or `$CODEX_HOME/prompts`).
+- Teach `openspec update` to refresh existing Codex prompts in-place (and only when they already exist) in the global directory, updating both frontmatter and body.

+## Why
+- GitHub Copilot supports custom slash commands through markdown files in `.github/prompts/<name>.prompt.md`. Each file includes YAML frontmatter with a `description` label and uses `$ARGUMENTS` to capture user input. This format allows teams to expose curated workflows directly in Copilot's chat interface.
+- Teams already rely on OpenSpec to manage slash-command configurations for Claude Code, Cursor, OpenCode, Codex, Kilo Code, and Windsurf. Excluding GitHub Copilot forces developers to manually maintain OpenSpec prompts in `.github/prompts/`, which leads to drift and undermines OpenSpec's "single source of truth" promise.
+- GitHub Copilot discovers prompts from the repository's `.github/prompts/` directory, making it straightforward to version control and share across the team. Adding automated generation and refresh through `openspec init` and `openspec update` eliminates manual synchronization and keeps OpenSpec instructions consistent across all AI assistants.
+
+## What Changes
+- Add GitHub Copilot to the `openspec init` tool picker with "already configured" detection similar to other editors, wiring an implementation that writes managed Markdown prompt files to `.github/prompts/` with OpenSpec marker blocks.
+- Generate three GitHub Copilot prompt files—`openspec-proposal.prompt.md`, `openspec-apply.prompt.md`, and `openspec-archive.prompt.md`—whose content mirrors shared slash-command templates while conforming to Copilot's frontmatter and `$ARGUMENTS` placeholder convention.
+- Document GitHub Copilot's repository-based discovery and that OpenSpec writes prompts to `.github/prompts/` with managed blocks.
+- Teach `openspec update` to refresh existing GitHub Copilot prompts in-place (only when they already exist) in the repository's `.github/prompts/` directory.
+- Document GitHub Copilot support alongside other slash-command integrations and add test coverage that exercises init/update behavior for `.github/prompts/` files.

+## Why
+- Kilo Code executes \"slash commands\" by loading markdown workflows from `.kilocode/workflows/` (or the global `~/.kilocode/workflows/`) and running them when a user types `/workflow-name.md`, making project-local workflow files the analogue to the slash-command files we already ship for other tools.\\
+  ([Workflows | Kilo Code Docs](https://kilocode.ai/docs/features/slash-commands/workflows))
+- Those workflows are plain markdown with step-by-step instructions that can call built-in tools and MCP integrations, so reusing OpenSpec's shared proposal/apply/archive bodies keeps behaviour aligned across assistants without inventing new content.
+- OpenSpec already detects configured tools and refreshes marker-wrapped files during `init`/`update`; extending the same mechanism to `.kilocode/workflows/openspec-*.md` ensures Kilo Code stays in sync with one source of truth.
+
+## What Changes
+- Add Kilo Code to the `openspec init` tool picker with \"already configured\" detection, including wiring for extend mode so teams can refresh Kilo Code assets.
+- Implement a `KiloCodeSlashCommandConfigurator` that creates `.kilocode/workflows/openspec-{proposal,apply,archive}.md`, ensuring the workflow directory exists and wrapping shared content in OpenSpec markers (no front matter required).
+- Teach `openspec update` to refresh existing Kilo Code workflows (and only those that already exist) using the shared slash-command templates.
+- Update documentation, release notes, and integration tests so the new workflow support is covered alongside Claude, Cursor, OpenCode, and Windsurf.

+## Why
+The current `openspec init` command requires interactive prompts, preventing automation in CI/CD pipelines and scripted setups. Adding non-interactive options will enable programmatic initialization for automated workflows while maintaining the existing interactive experience as the default.
+
+## What Changes
+- Replace the multiple flag design with a single `--tools` option that accepts `all`, `none`, or a comma-separated list of tool IDs
+- Update InitCommand to bypass interactive prompts when `--tools` is supplied and apply single-flag validation rules
+- Document the non-interactive behavior via the CLI init spec delta (scenarios for `all`, `none`, list parsing, and invalid entries)
+- Generate CLI help text dynamically from `AI_TOOLS` so supported tools stay in sync
+
+## Impact
+- Affected specs: `specs/cli-init/spec.md`
+- Affected code: `src/cli/index.ts`, `src/core/init.ts`

+## ADDED Requirements
+### Requirement: Non-Interactive Mode
+The command SHALL support non-interactive operation through command-line options for automation and CI/CD use cases.
+
+#### Scenario: Select all tools non-interactively
+- **WHEN** run with `--tools all`
+- **THEN** automatically select every available AI tool without prompting
+- **AND** proceed with initialization using the selected tools
+
+#### Scenario: Select specific tools non-interactively
+- **WHEN** run with `--tools claude,cursor`
+- **THEN** parse the comma-separated tool IDs and validate against available tools
+- **AND** proceed with initialization using only the specified valid tools
+
+#### Scenario: Skip tool configuration non-interactively
+- **WHEN** run with `--tools none`
+- **THEN** skip AI tool configuration entirely
+- **AND** only create the OpenSpec directory structure and template files
+
+#### Scenario: Invalid tool specification
+- **WHEN** run with `--tools` containing any IDs not present in the AI tool registry
+- **THEN** exit with code 1 and display available values (`all`, `none`, or the supported tool IDs)
+
+#### Scenario: Help text lists available tool IDs
+- **WHEN** displaying CLI help for `openspec init`
+- **THEN** show the `--tools` option description with the valid values derived from the AI tool registry
+
+## MODIFIED Requirements
+### Requirement: Interactive Mode
+The command SHALL provide an interactive menu for AI tool selection with clear navigation instructions.
+
+#### Scenario: Displaying interactive menu
+- **WHEN** run in fresh or extend mode without non-interactive options
+- **THEN** present a looping select menu that lets users toggle tools with Enter and finish via a "Done" option
+- **AND** label already configured tools with "(already configured)" while keeping disabled options marked "coming soon"
+- **AND** change the prompt copy in extend mode to "Which AI tools would you like to add or refresh?"

+## Why
+- Windsurf exposes "Workflows" as the vehicle for slash-like automation: saved Markdown files under `.windsurf/workflows/` that Cascade discovers across the workspace (including subdirectories and up to the git root), then executes when a user types `/workflow-name`. These files can be team-authored, must stay under 12k characters, and can call other workflows, making them the natural place to publish OpenSpec guidance for Windsurf users.\
+  ([Windsurf Workflows documentation](https://docs.windsurf.com/windsurf/cascade/workflows))
+- The Wave 12 changelog reiterates that workflows are invoked via slash commands and that Windsurf stores them in `.windsurf/workflows`, so the OpenSpec CLI just needs to generate Markdown there to participate in Windsurf's command palette.\
+  ("Custom Workflows" section, [Windsurf changelog](https://windsurf.com/changelog))
+- OpenSpec already ships shared command bodies for proposal/apply/archive and uses markers so commands stay up to date. Extending the same templates to Windsurf keeps behaviour consistent with Claude, Cursor, and OpenCode without inventing new content flows.
+
+## What Changes
+- Add Windsurf to the CLI tool picker (`openspec init`) and the slash-command registry so selecting it scaffolds `.windsurf/workflows/openspec-proposal.md`, `openspec-apply.md`, and `openspec-archive.md` with marker-managed bodies.
+- Shape each Windsurf workflow with a short heading/description plus the existing OpenSpec guardrails/steps wrapped in markers, ensuring the total payload remains well below the 12,000 character limit.
+- Ensure `openspec update` refreshes existing Windsurf workflows (and only those that already exist) in-place, mirroring current behaviour for other editors.
+- Extend unit tests for init/update to cover Windsurf generation and updates, and update the README/tooling docs to advertise Windsurf support.
+
+## Impact
+- Specs: `cli-init`, `cli-update`
+- Code: `src/core/configurators/slash/*`, `src/core/templates/slash-command-templates.ts`, CLI prompts, README

+## Why
+OpenSpec currently creates the root-level `AGENTS.md` stub only when teams explicitly select the "AGENTS.md standard" tool during `openspec init`. Projects that skip that checkbox never get a managed stub, so non-native assistants (Copilot, Codeium, etc.) have no entry point and later `openspec update` runs silently create the file without any context. We need to bake the stub into initialization, clarify the tool selection experience, and keep the update workflow aligned so every teammate lands on the right instructions from day one.
+
+## What Changes
+- Update `openspec init` so the root `AGENTS.md` stub is always generated (first run and extend mode) and refreshed from a shared utility instead of being tied to a tool selection.
+- Redesign the AI tool selection wizard to split options into "Natively supported" (Claude, Cursor, OpenCode, …) and an informational "Other tools" section that explains the always-on `AGENTS.md` hand-off.
+- Adjust CLI specs, prompts, and success messaging to reflect the new categories while keeping extend-mode behaviour consistent.
+- Update automated tests and fixtures to cover the unconditional stub creation and the reworked prompt flow.
+- Refresh documentation and onboarding snippets so they no longer describe the stub as opt-in and instead call out the new grouping.

+The update command SHALL refresh OpenSpec-managed files in a predictable manner while respecting each team's chosen tooling.
+
+#### Scenario: Updating files
+- **WHEN** updating files
+- **THEN** completely replace `openspec/AGENTS.md` with the latest template
+- **AND** create or refresh the root-level `AGENTS.md` stub using the managed marker block, even if the file was previously absent
+- **AND** update only the OpenSpec-managed sections inside existing AI tool files, leaving user-authored content untouched
+- **AND** avoid creating new native-tool configuration files (slash commands, CLAUDE.md, etc.) unless they already exist

+## 1. Implementation
+- [x] 1.1 Refactor `openspec init` to always generate the root `AGENTS.md` stub (initial run and extend mode) via shared helper logic.
+- [x] 1.2 Rework the AI tool selection wizard to surface "Natively supported" vs "Other tools" groupings and make the stub non-optional.
+- [x] 1.3 Update CLI messaging, templates, and configurators so the new flow stays in sync across init and update commands.
+- [x] 1.4 Refresh unit/integration tests to cover the unconditional stub and the regrouped prompt layout.
+- [x] 1.5 Update documentation, README snippets, and CHANGELOG entries that mention the opt-in `AGENTS.md` experience.
+
+## 2. Validation
+- [x] 2.1 Run `pnpm test` targeting CLI init/update suites.
+- [x] 2.2 Execute `openspec validate update-cli-init-root-agents --strict`.
+- [x] 2.3 Perform a manual smoke test: run `openspec init` in a temp directory, confirm stub + grouped prompts, rerun in extend mode.

+## Why
+Today’s process requires maintainers to merge the Changesets PR, cut a tag, and draft the GitHub release by hand. npm publish then runs from our existing workflow after the GitHub release is published. The human-in-the-loop steps (versioning, tagging, release notes) slow us down and risk drift between npm, tags, and changelog.
+
+## What Changes
+- Use the single `changesets/action` on pushes to `main` to either open/update the version PR or, when the release PR is merged, run our publish command automatically using repository secrets.
+- Add a `release` script that builds and runs `changeset publish` so the action handles version bumps, changelog commits, npm publish, and GitHub releases end-to-end.
+- Enable `createGithubReleases: true` so GitHub releases are created from the changeset data right after publishing.
+- Document the automated flow, required secrets, guardrails, and recovery steps (rollback, hotfixes).
+
+## Two-Phase Rollout (Two PRs)
+1) Phase 1 — Dry run (no publish)
+   - Update the existing `release-prepare.yml` to wire up `changesets/action` with `createGithubReleases: true` and a no-op `publish` command (e.g., `echo 'dry run'`).
+   - Keep `.github/workflows/release-publish.yml` intact. This avoids any publish path changes while we verify that the version PR behavior and permissions are correct.
+   - Add a repository guard (`if: github.repository == 'Fission-AI/OpenSpec'`) and a concurrency group for safety.
+
+2) Phase 2 — Enable publish and consolidate
+   - Add `"release": "pnpm run build && pnpm exec changeset publish"` to `package.json`.
+   - Change `release-prepare.yml` to use `with: publish: pnpm run release` and `env: NPM_TOKEN: \\${{ secrets.NPM_TOKEN }}` plus the default `GITHUB_TOKEN`.
+   - Remove `.github/workflows/release-publish.yml` to avoid double-publish. Publishing now happens when the version PR is merged.
+
+## Guardrails
+- Concurrency: `concurrency: { group: release-\\${{ github.ref }}, cancel-in-progress: false }` on the workflow to serialize releases.
+- Repository/branch guard: run publish logic only on upstream `main` (`if: github.repository == 'Fission-AI/OpenSpec' && github.ref == 'refs/heads/main'`).
+- Permissions: ensure `contents: write` and `pull-requests: write` for opening/updating the version PR; `packages: read` optional.
+
+## Rollback and Hotfixes
+- Rollback: revert the release PR merge (which reverts version bumps/changelog); if a tag or GitHub release was created, delete the tag and release; deprecate the npm version if necessary (`npm deprecate @fission-ai/openspec@x.y.z 'reason'`).
+- Hotfix (urgent, no pending changesets): create a changeset for the fix and merge the release PR; in emergencies, run a manual bump/publish but reconcile with Changesets by adding a follow-up changeset to align versions.
+
+## Required Secrets
+- `NPM_TOKEN` with publish rights for the `@fission-ai` scope.
+- Default `GITHUB_TOKEN` (provided by GitHub) for opening/updating the version PR and creating GitHub releases.
+
+## How the Maintainer Flow Changes
+| Step | Current process | Future process |
+| --- | --- | --- |
+| Prepare release | Merge changeset PR, then manually draft release notes and tags | Merge release PR; action updates versions and handles changelog automatically |
+| Publish npm package | Happens automatically after GitHub release | Happens automatically via `changeset publish` invoked by the action |
+| GitHub release | Draft manually and sync with changelog | Action creates GitHub releases from changeset data |
+| Docs/process | Follow manual tagging/release steps | Docs describe automated flow + recovery and hotfix paths |
+
+## Impact
+- Automation: reuse `.github/workflows/release-prepare.yml` (phase 1: dry-run, phase 2: publish) and remove `.github/workflows/release-publish.yml` in phase 2.
+- Package metadata: add `release` script to `package.json`.
+- Docs: update README or `/docs` to show the automated flow, secrets, guardrails, and recovery steps.
+
+## Acceptance Criteria
+- Phase 1: merges to `main` open/update a version PR; on merge, the action’s `publish` step is a no-op; no npm publish occurs; logs confirm intended behavior; GitHub releases creation is wired but inert due to no publish.
+- Phase 2: merges to `main` run `pnpm run release` from the action; npm package publishes successfully; GitHub release is created automatically; `.github/workflows/release-publish.yml` is removed; no duplicate publishes occur.

+## 1. Release workflow automation
+- [x] 1.1 Add a `.github/workflows/release.yml` that runs on pushes to `main`, sets up pnpm + Node 20, installs dependencies, and invokes `changesets/action@v1` with `publish: pnpm run release`.
+- [x] 1.2 Configure the action with `createGithubReleases: true` and document required secrets (`NPM_TOKEN`, default `GITHUB_TOKEN`) plus recommended concurrency safeguards.
+- [x] 1.3 Validate the workflow using `act` or a dry-run push to confirm the action opens release PRs when changesets exist and publishes when the release PR merge lands.
+
+## 2. Package release script
+- [x] 2.1 Add a `release` script to `package.json` that builds the project and runs `changeset publish` using pnpm.
+- [x] 2.2 Ensure the script respects the existing `prepare`/`prepublishOnly` hooks to avoid duplicate builds and update documentation or scripts if adjustments are needed.
+
+## 3. Documentation and recovery steps
+- [x] 3.1 Update maintainer docs (e.g., README or `/docs`) with the end-to-end automated release flow, explicitly removing the manual tag/release steps that are no longer required and explaining how changesets drive the release PR.
+- [x] 3.2 Document fallback steps for failed publishes (rerun workflow, manual publish) and the hotfix path when a release must be cut without pending changesets.

+# Add Archive Command Arguments
+
+## Why
+The `/openspec:archive` slash command currently lacks argument support, forcing the AI to infer which change to archive from conversation context or by listing all changes. This creates a safety risk where the wrong proposal could be archived if the context is ambiguous or multiple changes exist. Users expect to specify the change ID explicitly, matching the behavior of the CLI command `openspec archive <id>`.
+
+## What Changes
+- Add `$ARGUMENTS` placeholder to the OpenCode archive slash command frontmatter (matching existing pattern for proposal command)
+- Update archive command template steps to validate the specific change ID argument when provided
+- Note: Codex, GitHub Copilot, and Amazon Q already have `$ARGUMENTS` for archive; Claude/Cursor/Windsurf/Kilocode don't support arguments
+
+## Impact
+- Affected specs: `cli-update` (slash command generation logic)
+- Affected code:
+  - `src/core/configurators/slash/opencode.ts` (add `$ARGUMENTS` to archive frontmatter)
+  - `src/core/templates/slash-command-templates.ts` (archive template steps for argument validation)
+- Breaking: No - this is additive functionality that makes the command safer
+- User-facing: Yes - OpenCode users will be able to pass the change ID as an argument: `/openspec:archive <change-id>`
