If you're working on CockroachDB, this handles the project's specific commit message conventions so you don't have to memorize them. It analyzes your staged changes, prompts for issue numbers, writes properly formatted commit messages with the right package prefix, and generates release notes in the correct category. The real value is in the details: it knows when to use "bug fix" versus "backward-incompatible change", how to structure multi-commit PRs, and what actually needs a release note versus what doesn't. It's basically the team's style guide turned into an interactive assistant that walks you through each commit.
