Don Cheli: Changelog Auto-Generator

Instructions

  1. Determine the commit range:
  • Default: from the last semver tag to HEAD
  • With --from/--to: use the specified refs
  • With --version: use that as the new version number
  1. Run git log --oneline and parse conventional commit prefixes
  2. Map commit types to Keep a Changelog categories:
  • feat / feat! → Added (breaking changes go in a separate top section)
  • fix → Fixed
  • refactor / perf → Changed
  • docs → Changed
  • security → Security
  • deprecated → Deprecated
  • remove → Removed
  • test / chore / ci → omit by default (include with --verbose)
  1. Extract the short hash and append it to each entry for traceability
  2. Skip merge commits (Merge branch, Merge pull request)
  3. Insert the new section at the top of CHANGELOG.md, below the header — never overwrite existing entries
  4. If no CHANGELOG.md exists, create it with the standard Keep a Changelog header
  5. With --dry-run, print to stdout only — do not write to file
  6. After writing, confirm with the user and suggest git add CHANGELOG.md

Quality Gate

  • If fewer than 2 commits are found in the range, warn the user before generating
  • If breaking changes are detected (feat!, BREAKING CHANGE footer), highlight them prominently
  • Never infer a version number from non-semver tags — ask the user to provide --version
