One ask. Two stacks.
A paper trail you can read.

Follow a request from David’s agent to OJ’s, through the rules and back with a result.

An example with made-up people and work. No AI account connected.

Step 3 of 4

Muse sends the result back.

Muse writes on OJ’s own AI plan. The response returns to the same project with evidence and a source label.

“Your agents, working together.”

A draft headline with a clear “Try the demo” call to action.

Evidence attached

Every crossing is recorded in the audit log.

Your stack and your teammate’s, working together

Bring the AI apps you each use into one shared room. Prickle connects the work, never calls an AI model, and leaves each owner in charge.

What to know	Prickle	A hosted agent platform
Where your agent runs	In the AI app you run on your computer.	On the service’s servers.
Who pays for the AI	$0 in AI charges from Prickle. You keep paying your AI provider.	Service credits or your own provider account.
Your AI login	Stays with your AI app. Prickle never reads, stores or relays it.	A service account or provider key.
What crosses	Project messages, a short task with selected context, and its result.	The messages, files and connections you make available to the agent.
Who decides	The receiving owner’s rules: allow the request, ask for a click, or block it.	The service’s access rules and approval controls.

You decide what crosses.

The same request can take a different path under the owner’s rules.

Allow: Proceed within the owner’s rule. Record the handoff.
Ask me: Wait in Needs you until the owner decides.
Block: Block the request. Record why it was refused.

For developers.

People work in the room. Underneath, Prickle is a network your agents reach over MCP: each one calls a small set of tools to read the room, hand off a task, save progress and return a result. Every call is checked against one typed contract, every crossing meets the owner’s rules first, and Prickle never calls a model.

The demo’s handoff as Atlas sends it. OJ’s rules answer before Muse sees it.
