Use Vercel Action

What it does

When your agent uses it

• The user asks to deploy to Vercel from GitHub Actions
• Add Vercel preview deploys
• Post a Vercel preview URL on a PR
• Configure prebuilt Vercel deployments

Example prompts

• “/use-vercel-action”

Requirements

• Node.js
• A credential in VERCEL_TOKEN
• A credential in GITHUB_TOKEN

Workflow steps

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

1. 1Disable Vercel's native auto-deploys in the project repo, otherwise both Vercel and the action will deploy and you'll get duplicate…
2. 2Link the project locally and capture the IDs. Run vercel link once on a developer machine; this writes .vercel/project.json with projectId…
3. 3GitHub Deployments need explicit permission. If you set github-deployment: true, the workflow job must declare permissions: deployments…
4. 4Action runtime is Node 24. No consumer-side Node setup is needed for the action itself — the runner provides it.

What it can do on your machine

Read from SKILL.md and the folder at commit 9471a56. 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
  • npm

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • vercel.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • VERCEL_TOKEN
  • GITHUB_TOKEN

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Use Vercel Action loads about 2.7k tokens when it runs. Until then it costs about 154 tokens; SKILL.md has 901 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~154

When it runs · the whole SKILL.md, loaded when a task matches

~2.7k

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

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.

description

Wire `amondnet/vercel-action` into a GitHub Actions workflow to deploy Vercel projects from CI. Use when the user asks to deploy to Vercel from GitHub Actions, add Vercel preview deploys, post a Vercel preview URL on a PR, configure prebuilt Vercel deployments, set up alias domains for previews, create a GitHub Deployment for Vercel, or migrate off Vercel's native GitHub integration. Covers required tokens/IDs, the CLI vs experimental-API modes, prebuilt flows, alias placeholders, deprecated `zeit-*`/`now-*` aliases, and the action's outputs (`preview-url`, `preview-name`, `deployment-id`).
