vercel-optimize

vercel-optimize is a skill for Claude Code, Codex from robotostudio/turbo-start-sanity. It costs 116 tokens per session (3,976 once invoked), scanned A, a copy of vercel-optimize, MIT.

A guide and audit process for reducing cost and improving performance on deployed Vercel projects, especially those using Next.js, SvelteKit, Nuxt, or limited Astro setups. Vercel is a hosting platform for web applications.

In plain words
What is it for?
Use it to collect Vercel metrics and usage data, inspect approved code areas, and produce ranked recommendations with version-matched documentation references.
Why use it?
It bases recommendations on production measurements and investigates only specific routes, files, or settings identified by those measurements.

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents; installed under .agents/ (shared by several agents).

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node scripts/collect-signals.mjs [projectId] > "$RUN_DIR/vercel-signals.json" 2> "$RUN_DIR/collect.stderr".

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vercel-optimize scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

The scan reads SKILL.md. This mod also ships 58 executable files (lib/auth-route.mjs, lib/budget-summary.mjs, lib/citations.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 323 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vercel Optimize

Run an observability-first Vercel optimization audit. Do not inspect source files until signals.json exists and a deterministic gate points to a route, file, or project setting.

Core doctrine: read references/doctrine.md if any rule is unclear.

  • Metrics first. Recommendations start from Vercel production signals, not repo-wide grep.
  • Deterministic gates. scripts/gate-investigations.mjs decides what deserves investigation.
  • Candidate-bound scope. Read only files named by a candidate or a route-local import chain.
  • Version-aware citations. Use only references/docs-library.json; invalid or version-mismatched citations are stripped.
  • Customer copy. Read references/voice.md before writing report text or chat output.

Prerequisites

  • Vercel CLI v53+ with vercel metrics, vercel usage, vercel contract, and vercel api.
  • Authenticated CLI session: vercel login.
  • Linked app directory: vercel link. VERCEL_PROJECT_ID can help resolve project config, but vercel metrics still requires directory linkage. The link or environment must include the intended project org/team/user scope so the collector can resolve a CLI-safe --scope and keep vercel metrics, vercel usage, and vercel contract on the same account.
  • Node.js 20+.
  • Observability Plus for route-level metric-backed recommendations.

Never put auth tokens in shell commands. Do not type VERCEL_TOKEN=..., --token ..., or Authorization: Bearer ... into commands that may be echoed in chat.

Framework Support

The preflight reads package.json and sets expectations before metric fan-out.

Framework Status Notes
Next.js App Router supported strongest route mapping, scanners, playbooks, citations
Next.js Pages Router supported scoped to Pages Router idioms when detected
SvelteKit supported route mapping for src/routes files and SvelteKit scanner
Nuxt supported route mapping plus generic/platform checks; fewer framework-specific recs
Astro limited route mapping plus generic checks; fewer framework-specific recs
Hono / Remix / unknown blocked by default continue only if the user accepts a limited platform/code-only audit

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
