--- name: react-doctor description: 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. version: "1.2.0" ---

# 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.

## /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 — a scan → filter → triage → fix → validate loop that edits the working tree directly (never commits, never opens PRs). Updating the prompt at its source updates every agent on its next fetch — no skill reinstall needed.

Pair it with the matching per-rule prompts at `https://www.react.doctor/prompts/rules/<plugin>/<rule>.md` (fetched on demand inside the playbook) so each fix uses the canonical, reviewer-tested recipe.

## Configuring or explaining rules

When the user wants to understand a rule, disagrees with one, or wants to disable / tune which rules run (not fix code), read [references/explain.md](references/explain.md) and follow it. Start with `npx react-doctor@latest rules explain <rule>`, then apply the narrowest control via `npx react-doctor@latest rules disable|set|category|ignore-tag …`, which edits your `doctor.config.*` (or `package.json#reactDoctor`).

## Command

```bash npx react-doctor@latest --verbose --scope changed ```

| Flag | Purpose | | ----------------- | ---------------------------------------------------------------- | | `.` | Scan current directory | | `--verbose` | Show affected files and line numbers per rule | | `--scope changed` | Only report issues introduced vs the base branch (default: full) | | `--scope lines` | Only report issues on the changed lines | | `--score` | Output only the numeric score |
