How It Works

PR Commands

1. Fetches PR data via gh pr view
2. Detects placeholders in PR body (marked with HTML comments)
3. Calls Gemini AI to generate summary and changelog entries
4. Updates PR body via gh pr edit

Changelog Commands

1. Parses CHANGELOG.md as an AST using comrak
2. Collects merged PRs via gh pr list
3. Extracts changelog entries from PR bodies or titles
4. Inserts entries into the appropriate version section
5. Renders AST back to markdown

Release Commands

release next <level> - One Command, Done

The unified release workflow:

1. Get version: Runs cargo ws version <level> --dry-run to determine next version
2. Collect changelog: Gathers entries from merged PRs into CHANGELOG.md
3. Cargo workspace: Bumps versions, commits, tags, pushes, publishes to crates.io
4. GitHub Release: Creates release with notes from changelog

Dry-run mode (default): Shows what would happen, including changelog and release notes preview.

Execute mode (--execute): Performs all operations.

Other Commands

• enter-rc: Creates release branch, archives old changelog, merges alpha entries, generates AI highlights, creates PR, and publishes RC.1
• publish: Creates GitHub release with release notes from changelog
• stable: Merges RC versions (if multiple), updates changelog, publishes to crates.io, creates stable GitHub release, and merges the preparation PR to master

Conventional Commit Types

The bot recognizes these types in PR titles and changelog entries:
