Use for Vercel cost and performance optimization on deployed projects, especially Next.js, SvelteKit, Nuxt, and limited Astro apps. Collect Vercel metrics, usage, project config, and code scan results first; investigate only metric-backed candidates; produce ranked recommendations grounded in verified files and version-aware Vercel/framework docs. Trigger for Vercel bill reduction, slow or expensive routes, caching opportunities, Function Invocations, Build Minutes, Fast Data Transfer, Core Web Vitals, Bot Management, Fluid compute, or cost breakdown requests.

Contributing to vercel-optimize

Keep changes small, metric-grounded, and fixture-tested. Runtime code lives in skills/vercel-optimize; tests and fixtures live in packages/vercel-optimize-tests so installed skills stay small.

Rules

  • No runtime dependencies. Scripts use Node.js 20+ built-ins and the Vercel CLI.
  • No recommendation without a Vercel metric signal, code evidence when code changes are proposed, and an allow-listed citation.
  • No invented URLs, exact savings projections, or version-mismatched framework APIs.
  • No internal repo paths, service names, customer names, or captured private output in fixtures.
  • Keep generated report copy customer-facing. Put debug details behind --debug-out.

Output contracts

Every JSON-emitting script must be deterministic: stable key order, stable sort order, 2-space indentation, trailing newline. If a consumed schema changes, update the schema version and the fixture tests in the same PR.

    The `vercel-optimize` skill is a robust tool designed for performance and cost auditing of Vercel projects. It implements a 'metrics-first' doctrine, ensuring that any code investigation is preceded by an analysis of production telemetry fetched via the official Vercel CLI. The skill demonstrates high security standards, including deterministic gates to limit AI investigation scope, automated redaction of sensitive telemetry identifiers, and a verification framework to prevent hallucinations.

What it does

Runs a metrics-first audit of Vercel-deployed projects to identify cost and performance optimization opportunities. Collects production metrics, usage, and code signals, then gates candidates by verified impact before investigating Next.js, SvelteKit, Nuxt, and limited Astro apps. Produces ranked recommendations tied to actual route-level performance data and framework-aware documentation.

Frequently asked

Does this work with my framework?
Vercel Optimize supports Next.js (App Router and Pages Router), SvelteKit, and Nuxt with full metric-backed recommendations. Astro support is limited. Other frameworks like Hono or Remix can run a code-only audit but may not map route-level metrics back to source files.
What do I need to set up before running an audit?
You need Vercel CLI v53+, an authenticated session (`vercel login`), a linked app directory (`vercel link`), and Node.js 20+. Observability Plus is required for route-level metric-backed recommendations.
Does this require Observability Plus?
Observability Plus is required for route-level recommendations. Without it, the skill can still run a limited code-only audit if you accept the reduced scope.
What metrics does this collect and analyze?
The skill collects Vercel production signals via `vercel metrics`, `vercel usage`, and `vercel contract`, then gates investigations based on metric-backed candidates. It analyzes cost (Function Invocations, Build Minutes, Fast Data Transfer), performance (Core Web Vitals), and caching opportunities on a 14-day window.
Can I run this on unsupported frameworks?
Yes, but with limitations. The skill can run a platform/code-only audit for unsupported frameworks and will prompt you to accept the limited scope before proceeding.
