Performance Analysis Skill

Purpose

Measure before optimizing and preserve reproducible benchmark evidence.

Commands

Run Benchmark Suite

npx @claude-flow/cli performance benchmark --suite all

Profile Code

npx @claude-flow/cli performance profile --target ./src

Best Practices

1. Capture a baseline before changing code
2. Use identical inputs and environments
3. Report variance, not only the fastest result
4. Re-run correctness tests after optimization
