​
mellea.backends.tools.convert_tools_to_json(tools: dict[str, Callable])

Convert tools to json dict representation. Notes:
  • Huggingface transformers library lets you pass in an array of functions but doesn’t like methods.
  • WatsonxAI uses from langchain_ibm.chat_models import convert_to_openai_tool in their demos, but it gives the same values.
  • OpenAI uses the same format / schema.

​
mellea.backends.tools.json_extraction(text: str)

Yields the next valid json object in a given string.

​
mellea.backends.tools.find_func(d)

Find the first function in a json-like dictionary. Most llms output tool requests in the form ...{"name": string, "arguments": {}}...

​
mellea.backends.tools.parse_tools(llm_response: str)

A simple parser that will scan a string for tools and attempt to extract them.
