Vercel Deploy

Vercel Deploy

Deploy any project to Vercel instantly. Always deploy as preview (not production) unless the user explicitly asks for production.

Prerequisites

• Check whether the Vercel CLI is installed without escalated permissions (for example, command -v vercel).
• Only escalate the actual deploy command if sandboxing blocks the deployment network calls (sandbox_permissions=require_escalated).
• The deployment might take a few minutes. Use appropriate timeout values.

Quick Start

1. Check whether the Vercel CLI is installed (no escalation for this check):

command -v vercel

2. If vercel is installed, run this (with a 10 minute timeout):

vercel deploy [path] -y

Important: Use a 10 minute (600000ms) timeout for the deploy command since builds can take a while.

3. If vercel is not installed, or if the CLI fails with "No existing credentials found", use the fallback method below.

Fallback (No Auth)

If CLI fails with auth error, use the deploy script:

skill_dir="<path-to-skill>"

# Deploy current directory
bash "$skill_dir/scripts/deploy.sh"

# Deploy specific project
bash "$skill_dir/scripts/deploy.sh" /path/to/project

# Deploy existing tarball
bash "$skill_dir/scripts/deploy.sh" /path/to/project.tgz

The script handles framework detection, packaging, and deployment. It waits for the build to complete and returns JSON with previewUrl and claimUrl.

Tell the user: "Your deployment is ready at [previewUrl]. Claim it at [claimUrl] to manage your deployment."

Production Deploys

Only if user explicitly asks:

vercel deploy [path] --prod -y

Output

Show the user the deployment URL. For fallback deployments, also show the claim URL.

Do not curl or fetch the deployed URL to verify it works. Just return the link.

Troubleshooting

Escalated Network Access

If deployment fails due to network issues (timeouts, DNS errors, connection resets), rerun the actual deploy command with escalated permissions (use sandbox_permissions=require_escalated). Do not escalate the command -v vercel installation check. The deploy requires escalated network access when sandbox networking blocks outbound requests.

Example guidance to the user:

The deploy needs escalated network access to deploy to Vercel. I can rerun the command with escalated permissions—want me to proceed?

Pre-deploy Checklist

Before deploying:

• Confirm the project root and framework detection are correct.
• Check for uncommitted changes if the deployment should represent a specific git state.
• Identify required environment variables and whether they are already configured in Vercel.
• Prefer preview deployments unless the user explicitly asks for production.
• Use a long timeout for builds and report build logs if deployment fails.
• Do not expose secrets in terminal output, PR comments, or final messages.

Post-deploy Response

Return the deployment URL, whether it is preview or production, and any claim/manage URL produced by the fallback script. If the deploy command succeeds but runtime verification was not performed, say so directly. If verification is requested, use a normal browser or HTTP check only after the deployment URL is available.
