What problem does it solve? Vercel bills and slow routes are hard to diagnose because cost and latency issues hide across functions, caching, middleware, and build pipelines. This Skill replaces guesswork with an observability-first audit that ties every recommendation to real production metrics. ## Core Features & Use Cases - Metric-Backed Audits: Collects Vercel metrics, usage, contract, and project config via the Vercel CLI before reading any source code, then applies deterministic gates to select investigation candidates. - Ranked Recommendations: Produces verified recommendations with before/after code, file and line references, and version-aware documentation citations from a curated allow-list. - Framework-Aware Analysis: Supports Next.js (App and Pages Router), SvelteKit, and Nuxt route-to-file mapping, with limited Astro support and explicit blocking for unsupported frameworks. - Use Case: A team sees a rising Vercel bill and slow page loads. They run the audit, which finds an uncached hot route, ISR over-revalidation, and a broad middleware matcher, then delivers a report with concrete fixes and citations. ## Quick Start From your linked Vercel project directory, ask your coding agent to optimize this Vercel project and reduce its cost and slow routes.
