Walkthrough

The changes introduce a new ask_user tool that enables the agent to clarify ambiguous user intent by asking questions, and update the system instruction to require using this tool instead of guessing when requests are unclear.

Changes

Cohort / File(s)	Summary
Agent System Instructions lambda_agent/agent.py	Updated system_instruction to explicitly authorize asking users questions and added critical directive prohibiting the agent from guessing user intent; agent must use ask_user tool to clarify ambiguities and may ask multiple questions.
User Query Tool lambda_agent/tools.py	Added ask_user(question: str) -> str tool function that prompts the user via input() and returns their response; registered the tool in both TOOL_EXECUTORS and TOOL_FUNCTIONS for execution and schema generation.

Poem

🐰 Instead of guessing what's unclear,
Our agent now can ask to hear,
The user's voice flows crystal bright,
Ambiguity's solved just right! ✨
