# 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.
## Command
```bash
npx -y react-doctor@latest . --verbose --diff
```
| Flag | Purpose |
| ----------- | --------------------------------------------- |
| `.` | Scan current directory |
| `--verbose` | Show affected files and line numbers per rule |
| `--diff` | Only scan changed files vs base branch |
| `--score` | Output only the numeric score |
