You can scan a specific scope like a diff to main, a PR, a folder, or the whole codebase to identify useEffect anti-patterns causing unnecessary rerenders and wasted complexity, then apply or propose fixes based on the official React guidance.

You can analyze your specified code scope against official React guidance to pinpoint mismatches between effect intent and the dependency array, preventing stale data and incorrect dependency handling.

Yes, by running the analysis with the fix=true argument, you can automatically apply recommended useEffect refactoring changes to a pull request, directly implementing improvements to correct inefficient behavior.

This approach works for analyzing both a single component folder and the whole React codebase, allowing you to target specific scopes like a diff to main, a PR, or a directory to isolate effect issues efficiently.

Your React component rerenders in an infinite loop due to useEffect anti-patterns where effects trigger state updates unnecessarily, which this Skill identifies by reading official React guidance and analyzing your code scope to propose simplifications.
