Flow

This runs Flow type checking on React codebases, with support for different rendering environments like DOM, browser-specific code, React Native, and Fabric. You'll mostly use the default dom-node renderer, but it's nice that you can target native platforms when needed. The skill reminds you to always specify a renderer and watch for suppressed errors hiding behind FlowFixMe comments, which is honestly good advice since those can pile up and mask real issues. If you're working on a React project that uses Flow instead of TypeScript, this gives you a structured way to run type checks without having to remember which renderer flag to pass.
