performance-principles

Quick Review

This skill provides high-level performance principles and common pitfalls across backend and frontend layers. The structure is clear and well-organized, but the content is generic advice that doesn't offer actionable, system-specific guidance. The description adequately conveys what the skill contains, and the knowledge is reasonably comprehensive for general principles. However, novelty is low—these are widely-known best practices that a CLI agent could likely recite without this skill, and the guidelines lack concrete implementation details, code examples, or specific thresholds that would make them immediately actionable in a real codebase. The skill would benefit from system-specific metrics, actual code patterns, or links to implementation examples to increase its practical utility and justify its existence over general knowledge.
