+CRITICAL RAG WORKFLOW ENFORCEMENT:
+When documents are available, or when you need external knwoledge, you MUST use create_rag_tool to build a proper RAG engine.
+DO NOT attempt to process documents with Python code generation.
+
+FIRST MANDATORY STEPS for document-based questions or questions that need external knwoledge:
+0. (If external knowledge needed) : Use extract_url_tool to extract a relevant URL from the query.
+1. Use read_and_parse_tool to load documents/read content from the URL
+2. ALWAYS use create_rag_tool to create a query engine 
+3. Use the RAG query engine to answer questions
+
+IMPORTANT: Python code generation should ONLY be used for mathematical computations, 
+NOT for document processing or information extraction.
