Require Clarification from the Agent

A clarification stage checks whether the agent asks for information it does not have. It is a text-only objective, not a tool that fills in missing data silently.

For a controlled example, use AskingBaseStage with an incomplete instruction and an expected clarification:

from magma_core.simulation.stage import AskingBaseStage

stage = AskingBaseStage(
    question="Press the button I selected.",
    answer="Ask the user which button they selected.",
)
stage.global_parameters.reset_at_end = False

A following stage can supply the user's answer and then verify the corresponding action. The reset override preserves the scene while the user supplies the missing information. Use explicit instructions and linking to represent that interaction. Do not let a new independent parameter draw choose a different button from the one supplied in the answer.

The installed MissingInformationStage is a reusable domain-oriented alternative; inspect its constructor before selecting it. Validate both the clarification and subsequent action with GEN and a semantic judge.
