[Feature] Support for native function/tool calling in ReAct/ChatAdapter

[FireMasterK]

What feature would you like to see?

I would like to have native function calling support in ChatAdapter, to better avoid tool calling halucinations in ReAct. This would also allow models to make more than 1 tool call per completion.

Example error:

Adapter ChatAdapter failed to parse the LM response.

LM Response: I need to scrutinize the provided ...

[[ ## next_tool_name ## ]]

[[ ## next_tool_args ## ]]

Expected to find output fields in the LM response: [next_thought, next_tool_name, next_tool_args]

Actual output fields parsed from the LM response: [next_tool_name, next_tool_args]

Would you like to contribute?

• Yes, I'd like to help implement this.
• No, I just want to request it.

Additional Context

LiteLLM supports this here: https://docs.litellm.ai/docs/completion/function_call
