Use when finishing a React feature, fixing a React bug, or before committing React code, to check the react-doctor score did not regress. Also for a full React health scan, a focused UI design audit, a runtime trace of a slow React interaction, or explaining and tuning react-doctor rules.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# React Doctor
Scans React code for security, performance, correctness, accessibility and architecture issues, and scores it 0-100. GAIA pins the version every command below runs.
## After changing React code
```bash
npx -y react-doctor@{{REACT_DOCTOR_VERSION}} --verbose --scope changed
```
Check the score did not regress. If it dropped, fix the regressions before committing.
## Full scan
```bash
npx -y react-doctor@{{REACT_DOCTOR_VERSION}} --verbose
```
For general cleanup. Fix errors first, then warnings.
## UI design audit
```bash
npx -y react-doctor@{{REACT_DOCTOR_VERSION}} design --verbose
```
Runs only the design-tagged rules (composition, typography, interaction, accessibility, motion), including ones a general scan leaves opt-in.
## Runtime performance
For a vague "feels slow" or "janky" report, run this in an interactive terminal:
```bash
npx -y react-doctor@{{REACT_DOCTOR_VERSION}} scan <url> --format json
```

The line at the top of this page pins the label git:20261104.e4cb04d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
A 17 of 17 checks passed. Fixed automatic checks with no AI involved, so the same checks give the same answer every run.
