React Audit Grep Patterns

If you're auditing a React codebase before upgrading to 18.3.1 or 19, this is your grep command reference library. It catalogs every scan pattern you need to find deprecated APIs, unsafe lifecycle methods, async setState patterns, and React 19 specific removals. The skill emphasizes not relying on memory for grep syntax, especially for tricky multi-line patterns that need context flags. It's organized into four reference files covering React 18 scans, React 19 scans, test-specific issues, and dependency conflicts. Essentially a cheat sheet to avoid fumbling with grep flags while running migration audits.
