benchmark
Measure performance baselines and detect regressions across browser Core Web Vitals (LCP, INP, CLS, page weight), API endpoint latency percentiles, and build/test feedback times, with before/after comparison stored in git-tracked .ecc/benchmarks JSON. Use when checking page speed, responding to 'it feels slow' reports, verifying launch performance targets, or comparing stack alternatives.
Target: Software development & testing. Automatically collected · unverified.

Before and after a PR to measure performance impact Setting up performance baselines for a project When users report "it feels slow" Before a launch — ensure you meet performance targets Comparing your stack against alternatives Measures real browser metrics via browser MCP: Benchmarks API endpoints: Measures development feedback loop: Run before and after a change to measure impact: Output: Stores baselines in .ecc/benchmarks/ as JSON. Git-tracked so the team shares baselines. CI: run /benchmark compare on every PR Pair with /canary-watch for post-deploy monitoring Pair with /browser-qa for full pre-ship checklist
