What problem does it solve?

Performance bottlenecks across code, queries, and rendering slow down user experiences; this skill provides a disciplined approach to measuring, diagnosing, and eliminating those bottlenecks.

Core Features & Use Cases

• Systematic performance auditing using real measurements (Web Vitals, server timing) to identify bottlenecks.
• Optimizations across frontend and backend: parallel queries, memoization, code-splitting, caching, and efficient rendering strategies.
• Use Case: you notice slow page loads and refactors; apply the skill to find the slow hotspot and implement a targeted fix, then verify improvements with metrics.

Quick Start

Run a baseline performance audit on the critical page or API, identify the top bottleneck, implement a targeted fix, and re-measure to confirm improvement.
