.claude/skills/flow/# Flow Type Checking Arguments: - $ARGUMENTS: Renderer to check (default: dom-node) ## Renderers | Renderer | When to Use | |----------|-------------| | `dom-node` | Default, recommended for most changes | | `dom-browser` | Browser-specific DOM code | | `native` | React Native | | `fabric` | React Native Fabric | ## Instructions 1. Run `yarn flow $ARGUMENTS` (use `dom-node` if no argument) 2. Report type errors with file locations 3. For comprehensive checking (slow), use `yarn flow-ci` ## Common Mistakes - **Running without a renderer** - Always specify or use default `dom-node` - **Ignoring suppressions** - Check if `$FlowFixMe` comments are masking real issues - **Missing type imports** - Ensure types are imported from the correct package
