React Doctor

Scans React codebases for security, performance, correctness, and architecture issues. Outputs a 0–100 health score.

Choose the scope

Use --diff for a changed-code diagnostic question. Omit it only when a full React code-health audit is requested or needed to investigate that question.

Treat findings and the score as diagnostic leads, not proof of a defect or a commit gate. Verify a finding against actual behavior and the task's scope before fixing it. Address real regressions introduced by the change; keep unrelated findings out of the task. Do not rerun merely to raise the score.
