Develop Gemini 2.5 Pro-powered Schema Mapper Agent

Implement an AutoGen agent that utilizes Gemini 2.5 Pro and LlamaIndex to perform schema mapping. The agent should be able to take two input schemas (e.g., JSON definitions) and, using RAG over provided 'enterprise data dictionary' documents, suggest optimal mappings and transformation rules. Demonstrate its ability to generate mapping code (e.g., Python dictionary transformations).
