+# 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

+# 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.

+## Why
+Google is rolling out Antigravity, a Windsurf-derived IDE that discovers workflows from `.agent/workflows/*.md`. Today OpenSpec can only scaffold slash commands for Windsurf directories, so Antigravity users cannot run the proposal/apply/archive flows from the IDE.

+## Why
+Manual setup for new changes leads to formatting mistakes in spec deltas and slows agents who must recreate the same file skeletons for every proposal. A built-in scaffold command will generate compliant templates so assistants can focus on the change content instead of structure.
+
+## What Changes
+- Add an `openspec scaffold <change-id>` CLI command that creates a change directory (if it does not already exist) with validated `proposal.md`, `tasks.md`, and spec delta templates.
+- Update CLI documentation and quick-reference guidance so agents discover the scaffold workflow before drafting files manually, including reminders on when to create spec deltas.
+- Add automated coverage (unit/integ tests) to ensure the command respects naming rules, copies templates correctly, fails for existing directories, and produces output that passes `openspec validate --strict` untouched.
+
+## Impact

+## 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.

+# 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.
+- Document Codex support alongside other slash-command integrations and add regression coverage that exercises init/update behaviour against a temporary global prompts directory via `CODEX_HOME`.
+
+## Impact
+- Specs: `cli-init`, `cli-update`
+- Code: `src/core/config.ts`, `src/core/configurators/slash/*`, `src/core/templates/slash-command-templates.ts`, CLI tool summaries, docs
+- Tests: integration coverage for Codex prompt scaffolding and refresh logic
+- Docs: README and CHANGELOG entries announcing Codex slash-command support
+
+## Current Spec Reference
+- `specs/cli-init/spec.md`
+  - Requirements cover init UX, directory scaffolding, AI tool configuration, and the existing slash-command support for Claude Code, Cursor, and OpenCode.
+  - Our `## MODIFIED` delta in `changes/.../specs/cli-init/spec.md` copies the full "Slash Command Configuration" requirement (header, description, and all scenarios) before appending the new Codex scenario so archiving will retain every prior scenario.
+- `specs/cli-update/spec.md`
+  - Requirements define update preconditions, template refresh behavior, and slash-command refresh logic for Claude Code, Cursor, and OpenCode.
+  - The corresponding delta preserves the entire "Slash Command Updates" requirement while adding the Codex refresh scenario, ensuring the archive workflow replaces the block without losing the existing scenarios or the "Missing slash command file" guardrail.

+- 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.
+
+## Impact
+- Specs: `cli-init`, `cli-update`
+- Code: `src/core/configurators/slash/github-copilot.ts` (new), `src/core/configurators/slash/registry.ts`, `src/core/templates/slash-command-templates.ts`, CLI tool summaries, docs
+- Tests: integration coverage for GitHub Copilot prompt scaffolding and refresh logic
+- Docs: README and CHANGELOG entries announcing GitHub Copilot slash-command support
+
+## Current Spec Reference
+- `specs/cli-init/spec.md`
+  - Requirements cover init UX, directory scaffolding, AI tool configuration, and existing slash-command support for Claude Code, Cursor, OpenCode, Codex, Kilo Code, and Windsurf.
+  - Our `## MODIFIED` delta in `changes/.../specs/cli-init/spec.md` will copy the full "Slash Command Configuration" requirement (header, description, and all scenarios) before appending the new GitHub Copilot scenario so archiving retains every prior scenario.
+- `specs/cli-update/spec.md`
+  - Requirements define update preconditions, template refresh behavior, and slash-command refresh logic for existing tools.
+  - The corresponding delta preserves the entire "Slash Command Updates" requirement while adding the GitHub Copilot refresh scenario, ensuring the archive workflow replaces the block without losing existing scenarios or the "Missing slash command file" guardrail.

+## 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.
+
+## Impact
+- Specs: `cli-init`, `cli-update`
+- Code: `src/core/config.ts`, `src/core/configurators/(registry|slash/*)`, `src/core/templates/slash-command-templates.ts`, CLI wiring for tool summaries

@@ -0,0 +1,17 @@
+## 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.

+## Why
+Validation errors like "no deltas found" or "missing requirement text" do not tell agents how to recover, leading to repeated failures. Making error output specific about headers, required text, and next actions will help assistants fix issues in a single pass.
+
+## What Changes
+- Extend `openspec validate` error reporting so each failure names the exact header, file, and expected structure, including concrete examples of compliant Markdown.
+- Tailor messages for the most common mistakes (missing delta sections, absent descriptive requirement text, missing scenarios) with actionable fixes and suggested debug commands.
+- Update docs/help output so the improved messaging is discoverable (e.g., `--help`, troubleshooting section).
+- Add regression coverage to lock in the richer messaging for the top validation paths.

+## 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.

+## 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.

+# 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>`

+# Implementation Tasks
+
+## 1. Update OpenCode Configurator
+- [x] 1.1 Add `$ARGUMENTS` placeholder to OpenCode archive frontmatter (matching the proposal pattern)
+- [x] 1.2 Format it as `<ChangeId>\n  $ARGUMENTS\n</ChangeId>` or similar structure for clarity
+- [x] 1.3 Ensure `updateExisting` rewrites the archive frontmatter/body so `$ARGUMENTS` persists after `openspec update`
+
+## 2. Update Slash Command Templates
+- [x] 2.1 Modify archive steps to validate change ID argument when provided via `$ARGUMENTS`
+- [x] 2.2 Keep backward compatibility - allow inferring from context if no argument provided
+- [x] 2.3 Add step to validate the change ID exists using `openspec list` before archiving
+
+## 3. Update Documentation
+- [x] 3.1 Update AGENTS.md archive examples to show argument usage
+- [x] 3.2 Document that OpenCode now supports `/openspec:archive <change-id>`

+## Why
+Add support for Cline (VS Code extension) in OpenSpec to enable developers to use Cline's AI-powered coding capabilities for spec-driven development workflows.
+
+## What Changes
+- Add Cline slash command configurator for proposal, apply, and archive operations
+- Add Cline root CLINE.md configurator for project-level instructions
+- Add Cline template exports
+- Update tool and slash command registries to include Cline
+- Add comprehensive test coverage
+- **BREAKING**: None - this is additive functionality
+
+## Impact
+- Affected specs: cli-init (new tool option)
+- Affected code: src/core/configurators/slash/cline.ts, src/core/configurators/cline.ts, registry files
+- New files: .clinerules/openspec-*.md, CLINE.md

+## MODIFIED Requirements
+### 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/)
+- **AND** populate the managed block with a short stub that points teammates to `@/openspec/AGENTS.md`
+
+#### Scenario: Configuring CodeBuddy Code
+
+- **WHEN** CodeBuddy Code is selected
+- **THEN** create or update `CODEBUDDY.md` in the project root directory (not inside openspec/)
+- **AND** populate the managed block with a short stub that points teammates to `@/openspec/AGENTS.md`
+
+#### Scenario: Configuring Cline
+
+- **WHEN** Cline is selected
+- **THEN** create or update `CLINE.md` in the project root directory (not inside openspec/)
+- **AND** populate the managed block with a short stub that points teammates to `@/openspec/AGENTS.md`
+
+#### Scenario: Creating new CLAUDE.md
+
+- **WHEN** CLAUDE.md does not exist
+- **THEN** create new file with stub instructions wrapped in markers so the full workflow stays in `openspec/AGENTS.md`:
+```markdown
+<!-- OPENSPEC:START -->
+# OpenSpec Instructions
+
+This project uses OpenSpec to manage AI assistant workflows.
+
+- Full guidance lives in '@/openspec/AGENTS.md'.
+- Keep this managed block so 'openspec update' can refresh the instructions.
+<!-- OPENSPEC:END -->
+```
+
+### Requirement: Slash Command Configuration
+The init command SHALL generate slash command files for supported editors using shared templates.
+
+#### Scenario: Generating slash commands for Claude Code
+- **WHEN** the user selects Claude Code during initialization
+- **THEN** create `.claude/commands/openspec/proposal.md`, `.claude/commands/openspec/apply.md`, and `.claude/commands/openspec/archive.md`
+- **AND** populate each file from shared templates so command text matches other tools
+- **AND** each template includes instructions for the relevant OpenSpec workflow stage
+
+#### Scenario: Generating slash commands for CodeBuddy Code
+- **WHEN** the user selects CodeBuddy Code during initialization
+- **THEN** create `.codebuddy/commands/openspec/proposal.md`, `.codebuddy/commands/openspec/apply.md`, and `.codebuddy/commands/openspec/archive.md`
+- **AND** populate each file from shared templates so command text matches other tools
+- **AND** each template includes instructions for the relevant OpenSpec workflow stage
+
+#### Scenario: Generating slash commands for Cline
+- **WHEN** the user selects Cline during initialization
+- **THEN** create `.clinerules/openspec-proposal.md`, `.clinerules/openspec-apply.md`, and `.clinerules/openspec-archive.md`
+- **AND** populate each file from shared templates so command text matches other tools
+- **AND** include Cline-specific Markdown heading frontmatter
+- **AND** each template includes instructions for the relevant OpenSpec workflow stage
+
+#### Scenario: Generating slash commands for Cursor
+- **WHEN** the user selects Cursor during initialization
+- **THEN** create `.cursor/commands/openspec-proposal.md`, `.cursor/commands/openspec-apply.md`, and `.cursor/commands/openspec-archive.md`
+- **AND** populate each file from shared templates so command text matches other tools
+- **AND** each template includes instructions for the relevant OpenSpec workflow stage
+
+#### Scenario: Generating slash commands for OpenCode
+- **WHEN** the user selects OpenCode during initialization
+- **THEN** create `.opencode/commands/openspec-proposal.md`, `.opencode/commands/openspec-apply.md`, and `.opencode/commands/openspec-archive.md`
+- **AND** populate each file from shared templates so command text matches other tools
+- **AND** each template includes instructions for the relevant OpenSpec workflow stage
+
+#### Scenario: Generating slash commands for Windsurf
+- **WHEN** the user selects Windsurf during initialization
+- **THEN** create `.windsurf/workflows/openspec-proposal.md`, `.windsurf/workflows/openspec-apply.md`, and `.windsurf/workflows/openspec-archive.md`

+- **AND** populate each file from shared templates that map the first numbered placeholder (`$1`) to the primary user input (e.g., change identifier or question text)
+- **AND** wrap the generated content in OpenSpec markers so `openspec update` can refresh the prompts without touching surrounding custom notes
+
+#### Scenario: Generating slash commands for GitHub Copilot
+- **WHEN** the user selects GitHub Copilot during initialization
+- **THEN** create `.github/prompts/openspec-proposal.prompt.md`, `.github/prompts/openspec-apply.prompt.md`, and `.github/prompts/openspec-archive.prompt.md`
+- **AND** populate each file with YAML frontmatter containing a `description` field that summarizes the workflow stage
+- **AND** include `$ARGUMENTS` placeholder to capture user input
+- **AND** wrap the shared template body with OpenSpec markers so `openspec update` can refresh the content
+- **AND** each template includes instructions for the relevant OpenSpec workflow stage
