Perf — Performance Optimization v3.0
Measure, analyze, and optimize performance.
Actions
/perf audit <url>
Run Lighthouse via /browser-test and extract performance metrics:
- LCP (Largest Contentful Paint) — target < 2.5s
- FID (First Input Delay) — target < 100ms
- CLS (Cumulative Layout Shift) — target < 0.1
- TTFB (Time to First Byte) — target < 800ms
/perf bundle <path>
Analyze JavaScript bundle size:
- Total bundle size
- Per-chunk breakdown
- Tree-shaking opportunities
- Duplicate dependencies
/perf track
Compare current metrics against previous run:
- Store results in
.claude/quality-results/perf/ - Show delta (improved/regressed)
- Flag regressions as ADVISORY
Integration
/browser-testprovides raw Lighthouse data/gatesStage 5 (BROWSER) includes perf checks/shipchecklist includes perf audit
