Profile and optimize application performance including load times, memory usage, and rendering. Use when debugging slow performance, memory leaks, or optimizing app speed.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Performance Profiler ## Instructions When profiling performance: 1. **Identify the bottleneck type**: Network, rendering, memory, or compute 2. **Measure baseline** before optimizing 3. **Profile with appropriate tools** 4. **Apply optimizations** 5. **Measure improvement** ## Web Performance ### Core Web Vitals ```bash # Lighthouse CLI npx lighthouse https://yoursite.com --view # With specific metrics npx lighthouse https://yoursite.com --only-categories=performance ``` **Target Metrics**: | Metric | Good | Needs Work | Poor | |--------|------|------------|------| | LCP (Largest Contentful Paint) | < 2.5s | 2.5-4s | > 4s | | INP (Interaction to Next Paint) | < 200ms | 200-500ms | > 500ms | | CLS (Cumulative Layout Shift) | < 0.1 | 0.1-0.25 | > 0.25 | ### Bundle Analysis ```bash # Next.js ANALYZE=true npm run build # Webpack npx webpack-bundle-analyzer stats.json # Vite npx vite-bundle-visualizer ``` ## React Performance ### React DevTools Profiler 1.

How to install
mdr add onewave-ai/claude-skills/performance-profiler@sha256:e4072b6db7ba968dThe line at the top of this page pins the label git:20260225.309ae7a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
