Skill v1.0.1

Execute the finish-hotfix workflow (5 phases).
 
CRITICAL:
- Verify working tree is clean (`git status --porcelain` is empty) before finishing.
- Verify current branch matches `hotfix/*` before finishing — wrong branch type merges to the wrong parent.
See `${CLAUDE_PLUGIN_ROOT}/references/invariants.md` for details.
 
## Phase 1: Identify Version
**Goal**: Determine hotfix version from current branch or argument.
1. If `$ARGUMENTS` provided, use it as version (strip 'v' prefix if present)
2. Otherwise, extract from current branch: `git branch --show-current` (strip `hotfix/` prefix)
3. Store clean version without 'v' prefix (e.g., "1.0.1")
 
## Phase 2: Pre-finish Checks
**Goal**: Run tests before finishing.
1. Identify test commands (check package.json, Makefile, etc.)
2. Run tests if available; exit if tests fail
 
## Phase 3: Update Changelog
**Goal**: Generate changelog from commits.
1. Get previous tag: `git tag --sort=-v:refname | head -1`
2. Collect commits per `${CLAUDE_PLUGIN_ROOT}/references/changelog-generation.md`
3. Update CHANGELOG.md per `${CLAUDE_PLUGIN_ROOT}/examples/changelog.md`
4. Stage CHANGELOG.md: `git add CHANGELOG.md`
5. Determine the Claude model name for co-author attribution
   - Derive it from your own runtime model identity (e.g. Claude Opus 4.8) so it never goes stale; do not hardcode a fixed version
6. Commit with git-agent: `git-agent commit --no-stage --intent "update changelog for v$VERSION" --co-author "Claude <Model> <Version> <noreply@anthropic.com>"`
7. On auth error (401), retry with `--free`
8. **Fallback** (git-agent unavailable): `git commit -m "chore: update changelog for v$VERSION"` with conventional format and `Co-Authored-By` footer
 
## Phase 4: Finish Hotfix
**Goal**: Complete hotfix using git-flow-next CLI.
1. Run `git flow hotfix finish $VERSION --tagname "v$VERSION" -m "Release v$VERSION"`
2. Verify current branch: `git branch --show-current` (git-flow-next lands you on `main` after finish; `develop` is updated automatically). git-flow-next does NOT auto-push.
3. Push all: `git push origin main develop --tags`
 
## Phase 5: Finalize
**Goal**: Return to develop for ongoing work (git-flow-next leaves you on `main` after a hotfix finish).
1. Switch to develop: `git checkout develop`
2. Pull latest: `git pull origin develop`
3. Verify: `git branch --show-current` (should output "develop")
