What problem does it solve? React codebases accumulate lint violations, accessibility gaps, bundle bloat, and architecture issues that are hard to triage manually. This Skill runs automated diagnostics, assigns a 0-100 health score, and guides a scan-to-fix workflow so regressions are caught before commits. ## Core Features & Use Cases - Regression Checks: Run a changed-scope scan after edits to verify the health score did not drop before committing code. - Full Local Triage: Trigger the /doctor workflow to fetch the canonical playbook and follow a scan, filter, triage, fix, validate loop that edits the working tree directly. - Rule Configuration: Explain any rule, then disable, re-enable, re-severity, or ignore entire categories and tags by editing doctor.config or package.json. - Use Case: After refactoring a React feature, ask the agent to run react-doctor on changed files; if the score drops, it fixes the new errors and warnings before you commit. ## Quick Start Ask the agent to run react-doctor on the changed files and fix any issues that lowered the health score.
