 --------
 
-1. The `@ai_powered` decorator auto provide implementation for your python function with signature and docstring (call LLM underground)
-2. The `@make_tool` decorator turn your python function (with type annotations) into tools available by OpenAI API
-3. The `ChatBot` class can be inherited to create your own chatbot with tools empowered
-4. Full async support and sync compatible, use either style you want
-5. Strict type annotation (validated by pylance the strict mode)

When using it, make sure to convert the user's mathematical expression to a valid Python expression. Do not use any undefined functions; if the user's expression includes function calls, convert them to Python's built-in functions or syntax.
