What problem does it solve?

Eliminates subjective “feels slow” performance debates by turning frontend and backend performance into measurable numeric budgets with automated verification commands.

Core Features & Use Cases

• Cross-track performance thresholds: Defines numeric targets for Core Web Vitals, bundle size, API response latency, DB query time, and memory footprint.
• Verifier-ready measurements: Provides concrete command-based verification steps for Lighthouse metrics, bundle inspection, load testing, query logging, and RSS sampling.
• Stack-specific extension points: Lets stack skills inherit universal budgets and add probes, with explicit per-track exceptions to prevent silent divergence.
• Use cases: Set early perf gates for a new project, block regressions before release, and investigate reported performance incidents using consistent thresholds.

Quick Start

Ask the AI to set up performance budget acceptance criteria and wire the budget verifiers into verify-before-done for the release checklist.
