Report #98384

[architecture] Agent-to-agent messages are free-form text, so the receiver misreads intent or tool parameters

Adopt a schema-first envelope such as A2A Task/Part/Artifact; validate every inbound message against the schema and route by message type, not by parsing prose.

Journey Context:
Natural language is flexible but non-deterministic. In coordination, a single misread parameter causes cascading tool failures. A2A models communication as typed Tasks with Parts and Artifacts, and agents publish Agent Cards declaring accepted types. Validating inbound messages rejects silent drift and lets agents decide delegation from structured metadata rather than from LLM summaries.
