Gemini CLIAbout this skill
Use when declaring, measuring, or enforcing performance thresholds as a quality contract rather than as an aspirational target. Covers the three budget axes (time, size, count), the four governing properties of a real budget (metric, threshold, percentile, consequence), the Core Web Vitals set (LCP, INP, CLS), the RAIL model, Lighthouse budgets.json, lab vs field measurement, and the discipline of treating budget breach as a build or deploy failure rather than a tracked metric. Do NOT use for the activity of profiling and optimizing a specific slow path (use performance-engineering), the choice of rendering model that bounds achievable budgets (use rendering-models), or the design of observability and telemetry signals (use observability-modeling).
