Quick Review

Excellent skill for React useEffect best practices. The description clearly indicates when to use this skill (writing/reviewing useEffect, useState patterns). SKILL.md provides comprehensive guidance with a quick reference table, decision tree, and clear do/don't patterns that enable a CLI agent to understand when Effects are needed vs alternatives. Structure is clean with core guidance in SKILL.md and detailed examples delegated to referenced files. Task knowledge is strong, covering the philosophical framework and practical decision-making. Novelty is good—while useEffect is common, the nuanced guidance on avoiding unnecessary Effects and choosing alternatives (useMemo, key prop, event handlers) would require many tokens for an agent to derive independently. Minor point: slightly less novel than highly specialized technical skills, but the structured decision-making framework adds significant value.
