Build a real agent. Not a chatbot.

Tools it can actually call, documents it always has open, a JSON shape it must return, a budget of steps, and a test bench to prove it works before it goes live. The output is one manifest file — export it, version it, republish it.

Describe it

Tell the co-pilot what the agent should do. It asks one question at a time and writes the manifest as you answer — prompt, tools, allow-lists, output shape. Every field it fills stays editable in the steps above.

Start from one of these, or just describe your own idea below.

⌘↵ to send. Everything it writes lands in the steps on the left, where you can rewrite it.
