Report #77363

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

Enforce strict JSON Schema contracts at agent boundaries, using structured output generation \(constrained decoding\) rather than post-hoc parsing.

Journey Context:
Developers often let Agent A output free-text for Agent B to parse. LLMs are unreliable at adhering to implicit formats, and B's regex or JSON parser breaks, halting the chain. By forcing Agent A to generate via constrained decoding \(JSON mode/schema\), the contract is guaranteed structurally, allowing B to trust its input and fail fast on schema violations instead of hallucinated formatting. Post-hoc parsing adds fragile latency; structured generation bakes the contract into the inference process.
