nanoclaw-gws-ea: Skill for Claude Code

.claude/skills/add-vercel/container-skills/vercel-cli/SKILL.md

vercel-cli is a skill for Claude Code from taslim/nanoclaw-gws-ea. It costs 38 tokens per session (941 once invoked), scanned A, original, MIT.

A command-line tool for deploying web applications to Vercel, a hosting service for websites and web apps. It also manages Vercel projects, domains, and environment variables.

In plain words
What is it for?
Deploying preview or production versions of a web app, deploying from a chosen folder, managing Vercel projects, domains, and environment variables, and checking deployment status.
Why use it?
It gives a coding agent a defined way to publish an app, check its Vercel identity, and inspect a deployment without relying on interactive prompts.

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 8d 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 — 104 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.

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.
