vercel-auto-deploy — Claude Code hook: what it does, how to install

{
  "description": "Automatically trigger Vercel deployments when code changes are committed, with environment-specific deployment strategies and rollback on failure. Setup: Export environment variables 'export VERCEL_TOKEN=your_token' and 'export VERCEL_PROJECT_ID=your_project_id' (get your token from vercel.com/account/tokens and project ID from your Vercel dashboard). Hook triggers on PostToolUse for Write, Edit, and MultiEdit operations affecting source code files.",
