Four reviewers read your code at the same time, each looking at one thing: security, performance, correctness, or maintainability. A fifth agent, the review lead, combines their reports into one list ranked by severity, removes duplicates, and gives a single verdict (ship, fix first or do not ship) plus the three issues to fix first. Run it on a file or a diff with one command. Written for the Swarms framework (ConcurrentWorkflow) and runs on your own API key. Includes workflow.py.
