Quick Review

Exceptional React/Next.js performance optimization skill with comprehensive coverage of 40+ rules across 8 categories. The SKILL.md provides crystal-clear guidance on when and how to use the skill, with excellent quick-reference patterns and prioritization (Critical/High/Medium/Low). Structure is exemplary: concise overview in SKILL.md with detailed rules referenced in separate files. Strong task knowledge with actionable code examples and metrics. The skill addresses genuinely complex optimization patterns (waterfall elimination, bundle optimization, RSC performance) that would consume significant tokens for a CLI agent to derive independently. Minor deduction on novelty only because some JavaScript micro-optimizations are simpler patterns, though the React-specific and Next.js server component guidance is highly valuable. The implementation approach and common pitfalls sections demonstrate deep expertise. Overall, this is a production-ready skill that meaningfully reduces cost for performance optimization tasks.
