# AI code review on every GitHub pull request.

> Turn the reviewer on for a repository and add the review label (`ch-review` by default) to any pull request. CoderHelm reviews it like an engineer who knows the codebase, and keeps reviewing as you push.

*Product view: A CoderHelm review on GitHub: a risk level with the reason, a line comment with a suggested fix, and earlier comments resolved after they were fixed.*

## What a review includes

- Context beyond the diff: a code graph of definitions and callers shows what a change reaches
- Comments on the exact lines, with GitHub suggestions you can apply
- A risk level of low, medium or high; migrations, auth, secrets and payments always rate high
- A new review on every push, and its own comments resolved once they are fixed
- Answers in the thread: `@coderhelm` with a question, `@coderhelm re-review`, or the Re-request review button
- Draft pull requests are skipped until they are marked ready

## Options a repository can turn on

- **Auto merge, only when safe:** Off by default. Merges only the exact commit it reviewed, after a person approves and every check is green.
- **Runs the right CI:** Adds the labels your CI listens for, such as which end to end suites to run or a staging deploy, based on what the pull request changes. It uses the labels your repository already describes.
- **Holds the line on tests:** Sends back pull requests that change behavior without new or updated tests, and says what to test and where.
- **Release tags:** Tags a release after merges, grouping merges that land close together (within 15 minutes by default).
- **Deploy check:** With auto merge on, it waits for the deploy checks after the merge and reports only failures that are new. It never rolls back a shared branch.
- **Learns from your team:** Rate a review and add a note. Later reviews on that repository follow the feedback, on top of AGENTS.md and your review instructions.

## FAQ

### Does it review pull requests written by people?

Yes. Any pull request with the review label is reviewed, whoever wrote it.

### Can it merge on its own?

Only if you turn on auto merge for the repository, and even then only the exact commit it reviewed, after a person approves and every check passes.

### Where do I see past reviews?

The Reviewer page in the dashboard lists every review with its ratings, and lets you review a pull request on demand.
