react-doctor: a Claude Code skill by Million
Official
For React teams who want a health score and regression check before each commit. Skip it if you do not want Claude running npx packages or following a playbook fetched from the web.
Before you install: The /doctor mode fetches its playbook and per-rule prompts from react.doctor at run time and tells Claude to follow every step, so its instructions can change without any update to the skill.

What does react-doctor do?
react-doctor is a skill that runs the react-doctor CLI over React code and works from its 0 to 100 health score. After changes Claude runs npx react-doctor@latest --verbose --scope changed and fixes any drop before committing. A full scan, a design-only audit and a runtime scan of a URL are other modes; the runtime scan records a Chrome DevTools trace while you reproduce a slow interaction. Typing /doctor makes Claude download a triage playbook from react.doctor with curl and follow its scan, filter, triage, fix and validate loop, which edits files but never commits. It can also explain, disable or tune rules in doctor.config.
