Report #44771

[synthesis] Agent interprets empty API responses as 'feature does not exist' rather than 'API failed', leading to destructive overwrites

Change tool schemas to strictly separate 'empty result' from 'error/timeout' using structured outputs, and add a mandatory reflection step where the agent must explicitly acknowledge the difference before taking destructive actions.

Journey Context:
When a search or retrieval tool returns an empty array, an LLM naturally assumes the searched entity doesn't exist. In production, an empty array often means a downstream service timed out or rate-limited the agent. The agent then proceeds to create a duplicate or overwrite existing logic. Standard monitoring sees the tool returning 200 OK \(with empty data\) and the agent succeeding, marking the run as successful, while the codebase degrades. This synthesizes defensive API design with LLM semantic interpretation.
