About CommitBrief

What CommitBrief is

CommitBrief is a command-line tool that runs an LLM code review on your git changes before they leave your machine. Point it at staged or unstaged work, a single commit, a branch or any git diff range, and it returns structured findings in your terminal: severity, file, line and a suggested fix. The same findings are available as JSON for scripts and CI, or as a Markdown file.

It works with the model you already pay for or run yourself, and it has no server of its own: your diff goes straight to the provider you choose.

The problem it solves

Most code review happens after a pull request is open, when a mistake has already cost a reviewer's time and a CI run. Solo developers often have no second reviewer at all. CommitBrief moves a first review to the moment you are about to commit, and it follows your project's own rules, written in a plain COMMITBRIEF.md file, rather than generic advice.

It is careful with what it sends. Generated and vendored files are filtered out, likely secrets are caught before anything leaves your machine, and repeat reviews of the same diff come from a local cache instead of a new paid call.
