Report #64510

[synthesis] Partial tool success masked by output truncation or exit code 0 with non-empty stderr

Mandate structured output schemas with explicit boolean success flags and error payloads; prohibit summarization of tool outputs for validation checks

Journey Context:
Agents truncate tool outputs to save tokens, stripping stderr content that contains warnings or partial failures. Exit code 0 with summarized output creates false dependency satisfaction. Structured schemas force explicit failure serialization that survives truncation, separating transport success \(parsing\) from business logic success.
