Report #38298

[synthesis] Agent confidently proceeds after silent API failures causing null data corruption

Enforce strict schema validation on tool outputs; treat missing or null keys as hard stops requiring explicit user/agent clarification before proceeding.

Journey Context:
When an API returns an error JSON or empty data, agents often parse the response optimistically, extracting a null or empty string. This null propagates to the next step \(e.g., a database delete command filtering on id = null\), wiping data. Agents lack the intrinsic 'surprise' humans feel at an empty result. You must force a hard failure on structural anomalies rather than letting the agent assume success.
