vercel-cli

vercel-cli is a skill for Claude Code, Codex from nanocoai/nanoclaw. It costs 38 tokens per session (1,366 once invoked), scanned A, original, MIT.

A command-line setup for deploying web applications and managing Vercel projects, domains, and environment variables. Vercel is a hosting platform for websites and web apps.

In plain words
What is it for?
Use it to deploy, publish, or otherwise manage web applications on Vercel.
Why use it?
It gives agents a defined way to perform Vercel operations while handling authentication through OneCLI.

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-cli scanned grade A with 1 finding 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 4d ago.

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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

3. **Live URL responds** — `curl -sI <url> | head -1` should return `HTTP/2 200` (or another 2xx/3xx). A 404/500 means something's broken even though Vercel reported success.

How it starts

The opening of the file, as written. The whole thing — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vercel CLI

You can deploy web applications to Vercel using the vercel CLI.

HARD RULE: You MUST NOT write HTML, CSS, or JavaScript yourself. When asked to build a website or web app, you MUST delegate to a Frontend Engineer subagent (see "Building Websites" section below). This is not optional. Violation wastes your context window on code that belongs in a separate agent.

Auth

Auth is handled by OneCLI — the HTTPS_PROXY injects the real token into API requests automatically. The Vercel CLI requires a token to be present to skip its local credential check, so always pass --token placeholder on every command. OneCLI replaces this with the real token at the proxy level.

Before any Vercel operation, verify auth:

vercel whoami --token placeholder

If this fails with an auth error, ask the user to add a Vercel token to OneCLI. They can create one at https://vercel.com/account/tokens and register it via onecli secrets create on the host. Once added, retry vercel whoami.

Deploying

Always use --yes to skip interactive prompts and --token placeholder for auth (OneCLI replaces with real token).

# Deploy to production
vercel deploy --yes --prod --token placeholder

# Deploy from a specific directory
vercel deploy --yes --prod --token placeholder --cwd /path/to/project

# Preview deployment (not production)
vercel deploy --yes --token placeholder

After deploying, verify the live URL:

# Check deployment status
vercel inspect <deployment-url> --token placeholder

Pre-Send Checks (do this before sharing the URL)

Don't send the deployment URL to the user until you've confirmed it's actually working. At minimum:

  1. Local build passes — run npm run build (or the project's build command) before vercel deploy. If the build fails locally, fix it first; don't deploy broken code.
  2. Deployment succeeded — the vercel deploy output shows a "Production: https://..." URL and the status is READY (confirm with vercel inspect).
  3. Live URL respondscurl -sI <url> | head -1 should return HTTP/2 200 (or another 2xx/3xx). A 404/500 means something's broken even though Vercel reported success.
  4. Optional visual check — if agent-browser is loaded, open the URL and eyeball it. Helpful for catching broken layouts that a 200 response wouldn't reveal.

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.
