Report #44488

[frontier] Agents failing silently on multi-step tasks because reasoning is hidden in free-form text

Enforce JSON Schema contracts for intermediate 'thinking' steps using OpenAI Structured Outputs or Zod schemas, not just final outputs

Journey Context:
ReAct and chain-of-thought prompting rely on parsing 'Thought: ...' text, which is brittle and regex-dependent. Structured intermediate steps create verifiable contracts between sub-agents, enabling static analysis and deterministic validation of reasoning chains. Tradeoff: Increases token usage for JSON overhead and requires stricter prompt engineering. Alternative: Function calling only with no intermediate reasoning exposure. Why this wins: Production debugging requires knowing exactly why an agent made a decision at step 3; structured intermediates enable replay and regression testing of reasoning paths.
