Report #74074
[architecture] Unstructured text payloads cause cascading parsing failures between agents
Enforce strict JSON schema contracts \(e.g., using OpenAI Structured Outputs or Pydantic\) at agent boundaries, treating the schema as an immutable API contract.
Journey Context:
Developers often let agents chat in natural language because it's easy. However, LLMs are unreliable parsers of free-text for downstream programmatic use. When Agent B expects a specific format and Agent A deviates, Agent B either crashes or hallucinates a fix. Forcing structured output at the boundary makes the system deterministic at the seams, shifting Agent A's cognitive load from 'formatting' to 'content generation'. Tradeoff: slightly higher token cost and latency for schema enforcement, but massive reduction in cascading format errors.
