Create Changelog
Create a changelog backfilled with version history.
Step 1: Run $changelog-rules Skill
Run the $changelog-rules skill to load shared changelog conventions.
Step 2: Check for Existing Changelog
Use git rev-parse --show-toplevel to find the repository root. Look for the changelog file per $changelog-rules. If it already exists, use request_user_input to confirm overwriting it. If the user declines (chooses the free-form "Other" option or asks to abort), stop without running the remaining steps.
Step 3: Backfill Version History
Collect release history from the most authoritative source available:
- GitHub releases (preferred): Run
gh release list --limit 100 --json tagName,name,publishedAt,body to get release notes. For each release, parse the body into changelog entries.
- Git tags (fallback): If no GitHub releases exist, run
git tag --sort=-v:refname to list tags. For each consecutive tag pair, run git log <older-tag>..<newer-tag> --oneline to collect commit summaries.
For each version, classify entries into the standard change types and apply the changelog-worthiness criteria per $changelog-rules.
Step 4: Write Changelog
Write the changelog following the $changelog-rules file structure and conventions.
Step 5: Present the Result
Briefly summarize how many versions were backfilled and which source was used (GitHub releases or git tags).
