While adding self.format_tools(tools) correctly addresses the tool formatting issue, this method contains several other critical bugs that will likely prevent it from functioning as intended:

  1. AttributeError: Line 37 calls self.format_input_message(messages), but the base class method is named _format_input_message (with a leading underscore). This will cause a runtime error.
  2. Logic Error: Line 38 incorrectly sets the stop variable to None because list.append() operates in-place and returns None. Consequently, the stop=stop argument passed on line 40 will always be None, effectively losing all intended stop sequences.
  3. Redundancy: The _call_llm method already handles message formatting internally (via _format_input_message), making the call on line 37 unnecessary even if the name were correct.
  4. Missing State Update: Unlike the base class implementation in OpenAI, this override fails to increment messages[-1].api_calls, which may affect tracking or logic dependent on the number of API attempts.

I recommend refactoring this method to address these issues alongside the tool formatting fix.
