# 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 2. Run `git log --oneline <range>` and parse conventional commit prefixes 3. 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`) 4. Extract the short hash and append it to each entry for traceability 5. Skip merge commits (`Merge branch`, `Merge pull request`) 6. Insert the new section at the top of `CHANGELOG.md`, below the header — never overwrite existing entries 7. If no `CHANGELOG.md` exists, create it with the standard Keep a Changelog header 8. With `--dry-run`, print to stdout only — do not write to file 9. 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`
