Vercel Deployment AI Skill Guide (Claude)

Overview & Engine Architecture

Vercel turns Git pushes into immutable deployments. Preview covers non-production branches/PRs; Production tracks the production branch (or vercel --prod). Builds produce static assets, Node serverless functions, and optional Middleware—not long-lived custom servers. Agents keep secrets in Project Environment scopes (Development / Preview / Production), treat NEXT_PUBLIC_* as browser-exposed, pin Node versions, and debug from Build Logs (first real error, not the final exited with 1).
