| description | Use after editing React code, before committing, or when cleaning up a codebase. Runs the local react-doctor analyzer to surface state/effects, performance, security, accessibility, and architecture issues, and to flag health-score regressions vs the base branch. |
Scans React codebases for state/effects, performance, security, accessibility, and architecture issues. Outputs a 0–100 health score (higher is better).
Run pnpm react-doctor --verbose --diff and check the score did not regress.
If the score dropped, fix the regressions before committing.
Run pnpm react-doctor --verbose (without --diff) to scan the full codebase. Fix errors before warnings.
pnpm react-doctor --verbose --diff
| Flag | Purpose |
|---|---|
--verbose | Show affected files and line numbers per rule |
--diff | Only scan changed files vs base branch |
