Hi HN! I built `changelog-bot`, a small CLI/GitHub Action that generates CHANGELOG.md entries from your git history + release notes with AI.

I wanted something that: - doesn’t require labels or strict conventions - works in CI without scripting - can optionally use LLMs (OpenAI/Anthropic) but never requires them - falls back to a deterministic git/PR-based summary when no API key is set

Usage example:

  pnpm dlx @nyaomaru/changelog-bot --release-tag HEAD --dry-run

Or as a GitHub Action:

  - uses: nyaomaru/changelog-bot@v0

If AI keys are missing or fail, it still completes the run and annotates the PR with the fallback reason.

Still early-stage (`v0.x`) — would love feedback on: - CLI flags / defaults - whether the fallback behavior makes sense - edge cases from real repos
