react-doctor
Use when finishing a feature, fixing a bug, before committing React code, or when the user types `/doctor`, asks to scan, triage, or clean up React diagnostics. Covers lint, accessibility, bundle size, architecture. Includes a regression check and a full local-triage workflow that fetches the canonical playbook.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# React Doctor Scans React codebases for security, performance, correctness, and architecture issues. Outputs a 0–100 health score. ## After making React code changes: Run `npx react-doctor@latest --verbose --scope changed` and check the score did not regress. If the score dropped, fix the regressions before committing. ## For general cleanup or code improvement: Run `npx react-doctor@latest --verbose` (the default `--scope full`) to scan the full codebase. Fix issues by severity — errors first, then warnings. ## For a focused UI design audit: Run `npx react-doctor@latest design --verbose`. This selects only design-tagged UI composition, typography, interaction, accessibility, and motion rules, including focused rules that remain opt-in during a general health scan. ## /doctor — full local triage workflow When the user types `/doctor`, says "run react doctor", or asks for a full triage / cleanup pass (not just a regression check), fetch the canonical local-triage playbook and follow every step in it: ```bash curl --fail --silent --show-error \ --header 'Cache-Control: no-cache' \ https://www.react.doctor/prompts/react-doctor-agent.md ``` The playbook is the single source of truth —
- After making React code changes:
- For general cleanup or code improvement:
- For a focused UI design audit:
- /doctor — full local triage workflow
- Configuring or explaining rules
- Command
curl --fail --silent --show-error \ npx react-doctor@latest --verbose --scope changed
What does the react-doctor skill do?
Use when finishing a feature, fixing a bug, before committing React code, or when the user types `/doctor`, asks to scan, triage, or clean up React diagnostics. Covers lint, accessibility, bundle size, architecture. Includes a regression check and a full local-triage workflow that fetches the canonical playbook.
How do I install it?
Run `npx skills add millionco/react-doctor --skill react-doctor --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From millionco/react-doctor, a repository with 14,264 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
