Test & Refine Agent Interactions

Create a test suite for your multi-agent system using the provided 'sample_code.py' input from the evaluation module. Simulate the full workflow, ensuring the 'Code Reviewer Agent' correctly identifies issues and the 'Refactor Suggestor Agent' provides relevant improvements. Implement a basic feedback mechanism for the agents to learn from detected errors or sub-optimal suggestions. Provide the Python code for running this test scenario and capturing agent interactions and outputs.
