- Determine which package(s) the commit affects (use `git show <hash> --stat`)
- Verify a changelog entry exists in the affected package(s)
- For external contributions (PRs), verify format: `Description ([#N](url) by [@user](url))`
5.**Cross-package duplication rule:**
Changes in `ai`, `agent` or `tui` that affect end users should be duplicated to `coding-agent` changelog, since coding-agent is the user-facing package that depends on them.
6.**Add New Features section after changelog fixes:**
- Insert a `### New Features` section at the start of `## [Unreleased]` in `packages/coding-agent/CHANGELOG.md`.
- Propose the top new features to the user for confirmation before writing them.
- Link to relevant docs and sections whenever possible.
7.**Report:**
- List commits with missing entries
- List entries that need cross-package duplication
