Performance Review

shiplightai/agent-skills

Runs browser-based performance measurements against your live app, capturing Core Web Vitals (LCP, INP, CLS) plus load metrics, resource optimization, and bundle analysis. You get actual Performance API data, not static analysis. It's built around Google's 2024 thresholds and compares your numbers against HTTP Archive benchmarks. Best used before launches or when pages feel slow but you're not sure why. The five-phase approach is thorough, maybe overkill for a quick check, but if you need to justify performance work to stakeholders or catch what Lighthouse misses in local dev, it delivers the evidence.
