…ics#502) The StructuredOutput tool non-deterministically wraps user data in an extra {"output": <data>} envelope, causing schema validation to fail and structured_output to be None on ResultMessage. Detect the single-key wrapper during result parsing and strip it so callers always see the schema-conformant payload. Handles both cases: when the CLI returns the wrapped dict directly on structured_output, and when validation fails and the wrapped JSON only appears in the result text field.
