"@qiqing The server is of course a Durable Object. The application code is loaded using a Dynamic Worker Loader. On the client side it's an iframe sandbox that can postMessage() to its parent which provides it a Cap'n Web connection to its server. https://developers.cloudflare.com/workers/runtime-apis/bindings/worker-loader/ https://developers.cloudflare.com/workers/runtime-apis/bindings/worker-loader/"

"I wrote my own agent harness for this which was surprisingly easy. There's a system prompt which explains the environment but it's pretty short. Modern models don't need a lot of prompt engineering it seems. Though I think part of the trick is that I made the environment so simple that they have very little to think about. It's just like. write a singleton DO server write client code that can RPC to the server through this provided stub. Will likely open source at some point. Not ready quite yet"

"The sandbox is all set up by the environment so the agent can't break out of it. Basically the agent is instructed to write client.js and server.js and each is then loaded into their respective sandbox. Technically the iframe sandbox is not perfect since content-security-policy can't actually block everything today. I think WebRTC can break out. But it's good enough for keeping an agent from accidentally doing something insecure. https://twitter.com/i/web/status/2022810407711227985 https://twitter.com/i/web/status/2022810407711227985"

"Folks I did it again. I made another RPC system. I know it's a problem. But bear with me I think this is the best possible JavaScript RPC.
