How skin works

Questions

What is skin?
Your own copy of a web app with an AI agent inside it. You ask for a change in plain words, the agent edits the app's code, and the new version goes live only after it builds, boots, and passes its checks.
Who pays for the AI?
You do, on your own Cloudflare account. Every model call uses your sign-in, through Workers AI or an AI Gateway you own. skin never pays for your tokens and never holds a provider key.
Which models can I use?
Open models on Workers AI, such as GLM and Llama, or Claude and GPT through your own authenticated AI Gateway. You can switch any time with Cmd+K.
What if a change breaks the app?
A version that fails its build, boot, or checks never goes live. Every earlier version stays in the console, one click from rollback, and you can reset to the original.
What does signing in give skin access to?
Only what Cloudflare's consent screen lists for the account you pick. Signing out ends the session and revokes skin's access.
What does skin run on?
Cloudflare Workers, Durable Objects, and the Worker Loader. Each person gets their own app, chats, and version history.
