Project Spine for Remix

Project Spine reads your Remix route tree and server/client split, then compiles agent instructions that respect loaders, actions, and the data boundary.

What Spine detects in a Remix repo

• Route tree including nested and pathless routes
• Loaders and actions per route
• Server utilities (cookies, sessions)
• Deployment adapter (Node, Vercel, Cloudflare)
