Report #49589

[synthesis] Agent generates a dynamic script with an output schema that drifts from the orchestrator's expectation, causing null pointer exceptions

Require static type hints and output schema declarations in any dynamically generated code. The orchestrator must parse the declared schema before execution and validate the output against it, rejecting untyped dynamic tools.

Journey Context:
Agents often write Python/Bash scripts on the fly to accomplish tasks. If the generated script outputs a list instead of a dictionary, or changes a key name, the orchestrator attempting to parse the output will fail. In strongly typed systems, this is a compile error. In agent pipelines, the orchestrator often passes None or null to the next step, leading to a catastrophic null pointer exception in a critical downstream API. This synthesizes dynamic language anti-patterns \(duck typing\) with agent tool generation. Dynamic flexibility is an agent's enemy.
