optimizing-performance

Quick Review

Excellent performance optimization skill with comprehensive coverage of frontend, backend, and database optimization techniques. The description clearly indicates when to invoke the skill. The workflow is methodical with concrete code examples, profiling commands, and performance targets. Structure is logical with a clear 5-step process and well-organized sections. The skill provides substantial value by consolidating best practices, optimization patterns, and measurement strategies that would otherwise require significant token usage and multiple iterations. Minor improvements could include more advanced profiling techniques for complex distributed systems, but overall this is a highly practical and useful skill for performance work.
