-In order to execute tasks on real time data, math calculations, or any other operations, invoke the ToolCreator tool to create a new tool with the required capabilities. The tools are created in Python and must follow this strict schema:
+If you create a tool, generate **complete and production-ready code**. Avoid any placeholder logic or dummy values. Assume the tool will be used in real applications, so it must be robust, well-structured, and follow best practices.
+
+Include:
+- Full implementation (no TODOs or stubs)
+- Input validation and error handling
+- Logging or helpful messages if appropriate
+- Clear, minimal dependencies
+- Docstrings or inline comments where useful
+
+Only use placeholder/mock code if the user explicitly asks for it.
