Agent to Agent Protocols: Agent Cards, Delegation, Task Streaming

A shipping carrier publishes a signed description of its claims agent. Desk reads that description before it hands over a damage claim for a broken blender. The signature makes two promises:

• The description has not changed since it was signed.
• It was signed by whoever holds the signing key.

The signature makes no promise about the following:

• Whether the agent can do what the description says.
• Whether the agent will report its results honestly.
• Whether the agent may act for this customer, or whether Desk should send it this customer's data.
