What it does

Vercel Functions is an agent skill from vercel/vercel-plugin, published by the product's own GitHub organization. Vercel Functions expert guidance — Node.js/Bun/Python runtimes, Fluid Compute, long-duration (30 min) functions, large functions (5 GB bundles), Docker/OCI container images, plan limits, streaming, WebSockets, and Cron Jobs. Use when configuring, debugging, or optimizing server-side code running on Vercel.

Its SKILL.md is about 12k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.

It sits in Backend & APIs, covering Containers, Realtime and WebSockets and Backend development. It works with Vercel, Docker, Python and Node.js. The repository describes itself as: Comprehensive Vercel ecosystem plugin — relational knowledge graph, skills for every major product, specialized agents, and Vercel conventions. Turns any AI agent into a Vercel…

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

Remove export const runtime = 'edge' (or runtime: 'edge' in vercel.json / the config object).
Replace next/server Edge-only imports where applicable; the Web Request/Response handler signature is unchanged, so most route handlers…
If you pinned execution with the Edge-only preferredRegion, use regions in vercel.json instead.
Confirm Fluid Compute is on (default since April 23, 2025) and redeploy.

What it can do on your machine

Read from SKILL.md and the folder at commit 82fa491. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- vercel
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- openapi.vercel.sh
Also links to:
- vercel.com
- github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- CRON_SECRET
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Vercel Functions loads about 12k tokens when it runs. Until then it costs about 81 tokens; SKILL.md has 3,556 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~81
When it runs · the whole SKILL.md, loaded when a task matches: ~12k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

NoteMentions a .env fileSKILL.md:906

├─ Missing env vars? → Compare `.env.local` against Vercel dashboard settings

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 3,556 words (~12,123 tokens).
