Gives Claude five performance analysis tools for profiling code directly in conversation. The benchmark tool runs JavaScript snippets with statistical timing (p95, p99, ops/sec) and side-by-side comparisons. Memory analyze takes heap snapshots over time and uses linear regression to spot leaks. Big O estimate fits your timing data against common complexity classes and shows an ASCII growth curve. Bundle analyze inspects JavaScript bundles for size, compression, and tree-shaking opportunities. Load test hits HTTP endpoints with configurable concurrency and reports percentile latencies. Useful when you're optimizing hot paths, debugging memory issues, or need quick performance feedback without leaving the chat.
