# Changelog

Reply in the project conversation language (CLAUDE.md → Language); code, identifiers, paths and commit messages stay in English.

## Phase 1: Commits
`git describe --tags --abbrev=0` → `git log <tag>..HEAD --pretty=format:'%h %s'`; group by type (feat → Added, fix → Fixed, perf → Changed, `!`/BREAKING → Breaking, security fixes → Security). Non-standard messages go to "Other" with a note.

## Phase 2: Version
Propose the bump (breaking → major, feat → minor, else patch); the argument's version wins.

## Phase 3: Write
Draft the `## [X.Y.Z] — YYYY-MM-DD` section in Keep a Changelog format; "May I write `CHANGELOG.md`?" as one `AskUserQuestion`: write (Recommended) · adjust the draft first · not now. No tag is created here.

Verdict: `COMPLETE`. Next step — one `AskUserQuestion`: `/release-checklist X.Y.Z` (Recommended) · stop here.
