What it does
Changelog Generator reads your full git log since the last tagged release and produces a formatted CHANGELOG.md entry that follows the Keep a Changelog specification. It groups commits into sections by Conventional Commits type, resolves PR and issue numbers into clickable links, and sorts entries so the most significant changes appear first.
- Groups commits: Features, Bug Fixes, Performance, Chores, Documentation
- Resolves GitHub PR and issue numbers to full URLs
- Keep a Changelog format:
## [version] - YYYY-MM-DD - Supports version bump prompts: patch / minor / major
- Configurable output path and date format

Semver tip: Run Changelog Generator before tagging a release. Ask Claude to suggest the appropriate semver bump (patch/minor/major) based on whether any feat or BREAKING CHANGE commits are present in the log.
