What problem does it solve? React codebases accumulate lint violations, accessibility gaps, bundle bloat, and architecture problems that are hard to triage manually. This Skill runs automated diagnostics and produces a 0-100 health score so you can catch regressions before committing and systematically clean up issues by severity. ## Core Features & Use Cases - Regression Checks: Run a changed-scope scan after editing React code to verify the health score did not drop before committing. - Full Triage Workflow: The /doctor command fetches a canonical scan-filter-triage-fix-validate playbook that edits the working tree directly without committing or opening PRs. - Focused Design Audits: Run design-tagged rules covering UI composition, typography, interaction, accessibility, and motion. - Rule Configuration: Explain, disable, or tune individual rules, categories, and tags via doctor.config.* edits that preserve formatting. - Use Case: After finishing a feature, ask the agent to run react doctor on changed files; if the score regresses, it fixes the new issues before you commit. ## Quick Start Ask the agent to run react doctor on the changed files and fix any regressions before committing.
