Turn a list of commits or PRs into a Keep a Changelog entry, a SemVer version proposal, breaking changes with a migration guide and release notes your users can actually read.
Generate a clear commit message (Conventional Commits or free form) and a PR description with context, changes, how to test and risks, straight from your diff and ticket.
Turn a repo tree and key files into a clear map: architecture, how a request flows, glossary, risky areas and exactly where to start for your specific task.
