Deterministic React code scanner that installs as an agent skill
React Doctor is a deterministic React code-quality scanner built for AI coding agents. It analyzes a codebase via CLI and flags issues across state/effects, performance, architecture, security, accessibility, and maintainability, including overly complex functions and repeated JSX that should be extracted. Instead of relying on LLM guesswork, it produces reproducible audit results. The findings can be installed as an agent skill for Claude Code, Cursor, Codex, OpenCode and similar tools, so the same rules guide future fixes. It also ships a GitHub Actions CI mode that only reports issues introduced by the current pull request, and can record Chrome performance traces for runtime hotspots. A good fit for teams whose React code is partially written by agents, or any engineering team that wants a low-noise React quality gate in CI.
