+#### Branch Management
+
 - **Branch creation** - `just branch <name>` creates dated branches in `$USER/YYYY-MM-DD-<name>` format
-- **PR creation** - `just pr` creates PRs using first commit message as title, all commits in body
-- **PR checks monitoring** - Watches GitHub Actions checks with 5-second polling
-- **AI integration** - Displays GitHub Copilot and Claude Code review comments after checks complete
-- **PR merge** - `just merge` squash merges, deletes remote branch, returns to main, and pulls latest
 - **Branch escape** - `just sync` returns to main branch and pulls latest changes
+- **UTC date utility** - `just utcdate` prints UTC date in ISO format (used internally for branch names)
+
+#### PR Creation and Updates

 - **Web viewing** - `just prweb` opens current PR in browser
-- **Releases** - `just release <version>` creates GitHub releases with auto-generated notes

+- **Standalone Claude review** - `just claude_review` shows Claude's latest PR comment without re-running checks
+
+#### Merge and Release
