docs: remove GitHub Copilot from tools list

feat: add GitHub Copilot slash command support
Add GitHub Copilot as a natively supported AI tool with custom slash commands for OpenSpec workflow operations. This enables teams using GitHub Copilot to access /openspec-proposal, /openspec-apply, and /openspec-archive directly from Copilot's chat interface. Implementation: - Create GitHubCopilotSlashCommandConfigurator that writes prompts to .github/prompts/ directory with YAML frontmatter and $ARGUMENTS placeholder following GitHub Copilot's prompt format - Register GitHub Copilot in AI_TOOLS configuration and slash command registry for automatic init/update integration - Add comprehensive test coverage for prompt generation, updates, and extend mode detection - Update documentation (README and CHANGELOG) to include GitHub Copilot in the slash-command support table The implementation follows the existing SlashCommandConfigurator pattern and integrates seamlessly with openspec init and openspec update commands.

-# 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.

-
-## 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

+## Unreleased
+
+### Minor Changes
+
+- Add GitHub Copilot slash command support. OpenSpec now writes prompts to `.github/prompts/openspec-{proposal,apply,archive}.prompt.md` with YAML frontmatter and `$ARGUMENTS` placeholder, and refreshes them on `openspec update`.
+
+## 0.8.1
+
+### Patch Changes

+## How OpenSpec compares (at a glance)
+
+- **Lightweight**: simple workflow, no API keys, minimal setup.
+- **Brownfield-first**: works great beyond 0→1. OpenSpec separates the source of truth from proposals: `openspec/specs/` (current truth) and `openspec/changes/` (proposed updates). This keeps diffs explicit and manageable across features.
+- **Change tracking**: proposals, tasks, and spec deltas live together; archiving merges the approved updates back into specs.
+- **Compared to spec-kit & Kiro**: those shine for brand-new features (0→1). OpenSpec also excels when modifying existing behavior (1→n), especially when updates span multiple specs.

 ## How OpenSpec Compares

+### vs. spec-kit
+OpenSpec’s two-folder model (`openspec/specs/` for the current truth, `openspec/changes/` for proposed updates) keeps state and diffs separate. This scales when you modify existing features or touch multiple specs. spec-kit is strong for greenfield/0→1 but provides less structure for cross-spec updates and evolving features.
+
 ### vs. Kiro.dev
 OpenSpec groups every change for a feature in one folder (`openspec/changes/feature-name/`), making it easy to track related specs, tasks, and designs together. Kiro spreads updates across multiple spec folders, which can make feature tracking harder.

+## 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 numbered placeholders (`$1`, `$2`, …) bound to the arguments they supply. The workflow screenshot shared by Kevin Kern ("Codex problem analyzer") shows the format OpenSpec should target so teams can invoke curated workflows straight from the chat palette.
+- Teams already rely on OpenSpec to manage the slash-command surface area for Claude, Cursor, OpenCode, Kilo Code, and Windsurf. Leaving Codex out forces them to manually copy/paste OpenSpec guardrails into `~/.codex/prompts/*.md`, which drifts quickly and undermines the "single source of truth" promise of the CLI.
+- Codex commands live outside the repository (under the user's home directory), so shipping an automated configurator that both scaffolds the prompts and keeps them refreshed via `openspec update` eliminates error-prone manual steps and keeps OpenSpec instructions synchronized across assistants.
+
+## What Changes
+- Add Codex to the `openspec init` tool picker with the same "already configured" detection we use for other editors, wiring an implementation that writes managed Markdown prompts directly to Codex's global directory (`~/.codex/prompts` or `$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 adapting to Codex's numbered argument placeholders (e.g., `$1` for the change identifier or follow-up question text).
+- Document Codex's global-only discovery and that OpenSpec writes prompts directly to `~/.codex/prompts` (or `$CODEX_HOME/prompts`).
+- Teach `openspec update` to refresh existing Codex prompts in-place (and only when they already exist) in the global directory.
+- 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`.

+## 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.

+## 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.

+- 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
+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.

+## 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.

+## 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
+- [ ] 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`.
+- [ ] 1.2 Configure the action with `createGithubReleases: true` and document required secrets (`NPM_TOKEN`, default `GITHUB_TOKEN`) plus recommended concurrency safeguards.
+- [ ] 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.

+- [ ] 2.1 Add a `release` script to `package.json` that builds the project and runs `changeset publish` using pnpm.

Tabish Bidiwale	91941243a3	docs: remove GitHub Copilot from tools list	2025-10-09 02:18:27 +11:00
Tabish Bidiwale	8822557bcd	feat: add GitHub Copilot slash command support Add GitHub Copilot as a natively supported AI tool with custom slash commands for OpenSpec workflow operations. This enables teams using GitHub Copilot to access /openspec-proposal, /openspec-apply, and /openspec-archive directly from Copilot's chat interface. Implementation: - Create GitHubCopilotSlashCommandConfigurator that writes prompts to .github/prompts/ directory with YAML frontmatter and $ARGUMENTS placeholder following GitHub Copilot's prompt format - Register GitHub Copilot in AI_TOOLS configuration and slash command registry for automatic init/update integration - Add comprehensive test coverage for prompt generation, updates, and extend mode detection - Update documentation (README and CHANGELOG) to include GitHub Copilot in the slash-command support table The implementation follows the existing SlashCommandConfigurator pattern and integrates seamlessly with openspec init and openspec update commands.	2025-10-09 02:15:14 +11:00

Update documentation and changelog to reflect changes. * chore: mark all Codex slash command tasks as completed All tasks for the Codex slash command support feature have been implemented and tested. * docs: remove Codex-specific note from README Remove the Codex-specific installation note as it's no longer needed in the main setup instructions. This information is better suited for tool-specific documentation.	2025-10-09 01:55:47 +11:00
