# osx-commit

Create commits that match project style.

**Input**: No positional arguments. The orchestrator invokes `/osx-commit` after every phase write (PHASE1 / PHASE2 / PHASE3 / PHASE4 / PHASE5 / PHASE6); ad-hoc `/osx-commit` invocations operate on the user's currently staged or unstaged changes. Detect the commit standard from the project, draft a subject that matches, and commit. If no standard is detected and the user invoked ad-hoc, fall back to Conventional Commits and ask via `{{ASK_TOOL}}` only when there is genuine ambiguity (multiple standards matched).

**Steps**

1. **Check documentation** — grep `commit` in AGENTS.md / CONTRIBUTING.md / README.md. Follow conventions if defined.

   ```bash
   grep -i "commit" AGENTS.md CONTRIBUTING.md README.md 2>/dev/null
   ```

2. **Check config files** — `ls commitlint.config.js .commitlintrc .versionrc .gitmojirc`. If present, that standard is authoritative.

   ```bash
   ls commitlint.config.js .commitlintrc .versionrc .gitmojirc 2>/dev/null
   ```

3. **Detect standard** — Run `scripts/detect-commit-style`. Falls back to manual `git log --format="%s" -10` only when the script is absent.

   ```bash
   scripts/detect-commit-style
   ```

   | Pattern | Standard |
   |---------|----------|
   | `type:` or `type(scope):` | Conventional |
   | `type(scope):` (scope required) | Angular |
   | Emoji at start | Gitmoji |
   | Imperative verbs, no prefix | Classic |

4. **Apply standard** — Use the detected format:

   - **Conventional:** `type: description`
   - **Angular:** `type(scope): description` (body required)
   - **Gitmoji:** `emoji description`
   - **Classic:** `Verb description` (no prefix)

5. **Stage and review** — Confirm what will be committed before drafting the message.

   ```bash
   git add <files>
   git diff --staged
   ```

6. **Draft and commit** — Follow detected standard. See **Output** below and `references/standards.md` for the full type tables.

7. **Verify** — `git log -1 --format='%s'` returns the standard's prefix shape (e.g. `feat:` for Conventional).

**Output**

One minimal example per standard. The full per-type tables live in `references/standards.md`.

1. **Conventional Commits** — `type: description`

   ```
   feat(api): add rate limiting endpoint

   - Add token bucket middleware
   - Configure limits per route

   Closes #123
   ```

   Common types: `feat`, `fix`, `docs`, `style`, `refactor`, `perf`, `test`, `build`, `ci`, `chore`. Body wrapped at 72 chars; lowercase description, no trailing period; `!` before `:` flags incompatible commits.

2. **Angular** — `type(scope): description` (body required)

   ```
   fix(router): resolve lazy loading guard order

   Previously, the router would incorrectly resolve guards during
   lazy loading scenarios. This fix ensures guards are resolved
   in the correct order for all navigation types.

   - Fix guard resolution timing
   - Add integration tests

   Fixes #12345
   ```

   Scope is mandatory for non-`docs` types; body required (≥20 chars) except for `docs`. Types: `build`, `ci`, `docs`, `feat`, `fix`, `perf`, `refactor`, `test`.

3. **Gitmoji** — `emoji description`

   ```
   ✨ Add user authentication system
   ```

   ```
   🐛 Fix memory leak in image processor

   - Clear cache after batch processing
   - Add memory usage monitoring
   ```

   Common emojis: ✨ feat, 🐛 fix, 📝 docs, ♻️ refactor, 💄 style, 🔥 remove, 🚀 deploy, 🔒 security, ✅ tests, 🔧 config.

4. **Classic** — `Verb description` (no prefix)

   ```
   Fix PHASE6 workflow issues in openspec-auto

   - Return error for archived changes without state.json
   - Skip show_progress after PHASE6 (state deleted)
   ```

   Subject ≤50 chars ideal, 72 max. Capitalize first letter, no trailing period, imperative mood. Common verbs: Add, Fix, Update, Remove, Refactor, Release, Improve, Rename, Bump, Enable.

**Guardrails**

- **Use detected standard** — never bypass detection and force a different style. If detection is wrong, fix the project's history or config, not per-commit.
- **Ask only on genuine ambiguity** — use `{{ASK_TOOL}}` only when multiple standards matched the detection thresholds. Single-match standard → commit without asking.
- **Never amend published commits** — if the commit has been pushed, use a follow-up commit. `--amend` is allowed only for local, unpushed commits.
- **Verify before commit** — `git log -1 --format='%s'` after commit must match the detected standard's prefix shape.
