What problem does it solve?
This Skill replaces unreliable performance impressions with reproducible measurements, baselines, comparisons, and clear ship-or-hold decisions.
Core Features & Use Cases
- Frontend Performance: Measure Core Web Vitals, Lighthouse scores, network requests, and bundle sizes.
- API and Database Benchmarking: Evaluate response-time percentiles, error rates, load behavior, and query execution plans.
- Regression Detection: Compare before-and-after metrics, apply warning and blocking thresholds, and integrate performance checks into CI.
- Use Case: Before merging a frontend change, establish a three-run baseline, measure the candidate build, compare LCP, INP, CLS, bundle size, and API latency, then document whether the change is safe to ship.
Quick Start
Use the benchmark skill to establish a baseline for the specified page or endpoint, measure it three times, compare the results with the candidate version, and produce a ship-or-hold report.
