Setup Deploy
Configure deployment settings for /land-and-deploy. Detects your deploy
platform (Fly.io, Render, Vercel, Netlify, Heroku, GitHub Actions, custom),
production URL, health check endpoints, and deploy status commands. Writes
the configuration to CLAUDE.md so all future deploys are automatic.
Use when: "setup deploy", "configure deployment", "set up land-and-deploy",
"how do I deploy with gstack", "add deploy config".
