Build a Streamlit Interface for Agent Interaction

Develop a basic Streamlit application that allows a user to upload a set of documents (simulated by text files) and trigger the multi-agent compliance analysis. The interface should display the progress of the agents and present the final compliance report generated by the 'Report Generator' agent. Include sections for identified risks, their severity, and suggested recommendations. Show the key Streamlit components and how they would interact with your Claude Agents SDK backend.
