What problem does it solve? Vercel bills and slow routes are hard to diagnose without connecting production metrics to specific code. This Skill runs an observability-first audit that collects Vercel metrics, usage, and project config, then investigates only the routes and files that deterministic gates flag, producing ranked recommendations with verified citations. ## Core Features & Use Cases - Metric-backed investigation: Collects route-level function invocations, duration, cache hit rates, Core Web Vitals, ISR, and billing usage via the Vercel CLI before reading any source files. - Deterministic gating and verification: Pure-JavaScript threshold gates select candidates, and a verification step strips invalid citations, blocks contradictory recommendations, and withholds weak findings. - Use Case: Ask your coding agent to optimize a deployed Next.js app with a rising Vercel bill; the skill identifies uncached hot routes, cold-start-heavy functions, and ISR over-revalidation, then returns before/after code fixes with version-aware documentation citations. ## Quick Start From a linked Vercel project directory, ask your coding agent to optimize this Vercel project and reduce its bill.
