## Overview

Reviews every opened pull request. Comments inline on risky changes, flags missing tests, and posts a plain-English summary for the author.

## How it works

1. Runs when a pull request is opened.
2. Read the diff and post review comments with GitHub.

## Example output

Pull request opened: “Cache revision lookups”

1. Read the pull request and its diff
2. Flagged one risky change in the cache invalidation path
3. Left inline comments on the three files it touched

Reviewed — the change looks sound apart from the invalidation path, where a stale entry can survive a revision bump. I've commented inline and summarised on the PR.

## How to set this up

1. Use it for free. Agenta creates the agent from this template in your workspace.
2. Connect GitHub. Each app connects from the setup screen.
3. Test, then let it run. Run it once to check the result. Then the trigger takes over.
