Enforce the no-useEffect rule when writing or reviewing React code. Activate when writing React components, refactoring existing useEffect calls, reviewing PRs that introduce useEffect, or when an agent adds useEffect "just in case." Provides five replacement patterns and the useMountEffect escape hatch.

From the source SKILL.md

Never call useEffect directly. Use derived state, event handlers, data-fetching libraries, or useMountEffect instead.
