Create Changelog

Create a changelog backfilled with version history.

Step 1: Run `$changelog-rules` Skill

Run $changelog-rules to load shared changelog conventions.

Step 2: 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 3: Check for Existing Changelog

If the changelog file already exists, warn the user and confirm before overwriting.

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).
