Vercel Ship Kit

Your agent can write code. Can it ship code? This skill bridges the gap between it works locally and it is live in production.

Built from dozens of real Vercel deployments -- static sites, serverless APIs, Next.js apps, and hybrid architectures. Every deployment pattern has been debugged in production.

What your agent learns:

Deployment -- Ship to Vercel via CLI with proper build configuration, environment variables, and domain setup. Handle the common deployment failures before they happen.

Serverless Functions -- Build API routes that work on Vercel serverless. Proper cold start handling, timeout management, file system access patterns, and response streaming.

Domain Configuration -- Set up custom domains, handle www vs non-www, configure SSL, and resolve domain conflicts between projects.

Environment Variables -- Manage secrets across preview, development, and production environments. Never leak credentials.

Project Structure -- Organize projects so Vercel builds correctly. Handle cleanUrls, rewrites, redirects, and headers in vercel.json.

Zero-Downtime Updates -- Deploy updates without breaking existing traffic. Rollback patterns when things go wrong.

Gotchas documented:

• Domain conflicts between Vercel projects (and how to resolve)
• Serverless function file system access (what works, what does not)
• Build cache issues and how to bust them
• Environment variable scoping surprises
• The cleanUrls + rewrite interaction trap
• Why your API route returns HTML (and how to fix it)
