performance-patterns

What problem does it solve?

This Skill ensures performance optimizations are targeted at issues that genuinely affect functionality or user experience, preventing premature optimization. It guides the user through understanding performance requirements, identifying bottlenecks in critical paths, and providing specific, benchmarked optimizations, leading to a faster and more reliable system.

Core Features & Use Cases

• Context-Aware Performance Analysis: Mandates understanding functionality requirements and performance constraints (latency, throughput, scale) before checking.
• Functionality-Focused Bottleneck Identification: Maps performance issues directly to their impact on user flows, system flows, or stability.
• Specific, Benchmarked Optimizations: Provides concrete code examples for fixing N+1 queries, O(n²) algorithms, memory leaks, and more, with expected performance improvements.
• Priority Classification: Ranks performance issues as Critical (blocks functionality), Important (degrades UX), or Minor (optimizations), ensuring focus on high-impact fixes.
• Use Case: When a file upload feature is reported as "slow," use this skill to first verify the functionality, then identify the performance requirements (e.g., <30s upload), and systematically analyze for bottlenecks like N+1 queries in the file listing or slow CRM API calls.

Quick Start

Analyze the performance of the user dashboard's data loading, focusing on queries that might be causing slow response times.
