React Expert

When you need to know how a React API actually works, not how you remember it working, this skill tears through the React repo looking for test files, source code warnings, PR discussions, and git history. It deliberately ignores LLM training data because React moves fast and common patterns get outdated. Each query spawns six parallel research agents that dig through different parts of the codebase and GitHub metadata. The output reads like an exhaustive API audit with file paths, line numbers, and exact code snippets. Worth using when you're implementing something tricky, debugging unexpected behavior, or writing docs that need to be correct rather than plausible. The skepticism mandate is the real feature here.
