Report #90819

[architecture] Unstructured text passing between agents causes cascading parsing failures

Enforce strict JSON Schema or Pydantic model validation at the receiver agent's boundary, treating the output of the generating agent as an untrusted API payload.

Journey Context:
Developers often rely on prompt instructions like 'output JSON' to coordinate agents. LLMs inevitably drift, add conversational filler, or omit keys. When the downstream agent receives malformed input, it hallucinates or crashes. By treating inter-agent communication as an API contract with programmatic validation, you fail fast and can trigger retries at the generator level before corrupting the downstream agent's context window.
