Runs a linter-style health check across your React codebase and gives you a 0-100 score with specific file paths and line numbers for every issue it finds. It catches 47+ patterns across security (hardcoded secrets, eval), performance (layout thrashing, transition-all abuse), architecture problems (nested component definitions, barrel imports killing your bundle), and Next.js-specific gotchas like missing metadata or async client components. The workflow is simple: run it, fix the errors first, then rerun to watch your score climb. Honestly feels like having a senior dev audit your project without the awkward Slack thread about why you're still importing all of lodash.
