Technical agent card

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

Provider: Sombra — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 1.0.0
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:

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