Re-ask every unanswered question from the assistant's preceding message through native
structured input (AskUserQuestion in Claude Code, request_user_input in Codex).
- Preserve the question order and any existing options or recommendation.
- For a question without options, offer two or three mutually exclusive choices. Put the recommended choice first and explain each choice's tradeoff in one sentence.
- Batch independent questions up to the tool's limit. Ask dependent questions after the earlier answers.
- When structured input is unavailable, ask one plain-text question at a time.
- When no unanswered question exists, say so and stop.
