Report #81872
[architecture] Cascading parse failures from unstructured inter-agent communication
Enforce strict JSON Schema contracts at agent boundaries using constrained decoding \(e.g., structured outputs\) rather than relying on prompt-based formatting.
Journey Context:
Developers often ask agents to 'respond in JSON' via prompts, but LLMs frequently hallucinate malformed JSON or include conversational text. Downstream agents then crash trying to parse it. Constrained decoding guarantees syntactic validity. The tradeoff is a slight increase in latency and stricter prompt engineering, but it eliminates an entire class of brittle regex-parsing errors in multi-agent pipelines.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
