Built by the team at Million, which has spent the last 3 years creating open source developer tools like React Scan, React Grab, and Million.js, used by 100k+ developers and starred 40k+ times on GitHub. They are now building Ami, a native local desktop environment for running coding agents with full machine access and context.
The react-doctor skill is a validation pass for React work. It is intended to catch problems in a codebase after a feature or bug fix has already been implemented, rather than during the first drafting step.
In practice, use it near the end of a React task to surface regressions, anti-patterns, or structural issues before shipping. It is most useful as a follow-up check after component, hook, or rendering logic changes.
