Tool usage returns BadRequestError: stop_details Extra Inputs are not permitted

[SteveMeli]

When creating a basic tool as a function using the anthropic provider, the tool is called but the response message to the API is malformed and raises an error.

I have tried with the example code from the agent docs and get the same outcome.

Versions

ActiveAgent 1.0.1
Anthropic 1.35.0

Expected outcome

Tool usage should be passed back to anthropic successfully

Actual output

The call raises an error after the tool is called

[ActiveAgent] [Anthropic] Prompt completed: model=xxxx messages=1 stream=false tokens=614/59 finish=tool_use 1591.8ms
Geocoding query: 1 High Street, London
 [ActiveAgent] [Anthropic] Tool call: geocode (0.2ms)
[ActiveAgent] [Anthropic] Prompt completed: messages= stream= 883.0ms
[ActiveAgent] [Anthropic] Prompt completed: messages= stream= 2481.7ms
5:in `<main>': {:url=>"https://api.anthropic.com/v1/messages", :status=>400, :body=>{:type=>"error", :error=>{:type=>"invalid_request_error", :message=>"messages.1.stop_details: Extra inputs are not permitted"}, :request_id=>"req_XXXX"}} (Anthropic::Errors::BadRequestError)

It seems that the tool response sent back to anthropic is malformed? Or contains the stop details from the tool response.

Many thanks

I've done some further investigation and I can see that the api_parameters passed back after the tool invocation has a nil stop_detail key. When that's removed the query works correctly.

I think it might be a new key being returned in later versions of the anthropic sdk or API.

This PR works locally for me.
