Your agent needs a mailbox. Give it one that is actually its own.

Here is the loop that keeps breaking. You ask an agent to sign up for something. The service sends a confirmation code. The agent cannot read your email, so it stops and asks you, and the whole point of delegating the task evaporates.

With an Echos address the agent has somewhere to receive that code. It can wait for the message to arrive rather than polling and hoping. It pulls out the code, finishes the signup, and tells you what it did.

You get the receipts either way. Everything that address ever received stays readable, and the dashboard logs which agent asked for what.
