Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Protocol: a2a
Version: 1.0.0
Extensions: https://ylang.education/extensions/ag-ui/v1
AG-UI protocol

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:
supportedInterfaces

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
