> camel-ai - Missing tool information when returning function call response
> -------------------------------------------------------------------------
>
> Key: CAMEL-21816
> URL: https://issues.apache.org/jira/browse/CAMEL-21816
> Project: Camel
> Issue Type: Bug
> Components: camel-ai, camel-langchain4j-tools
> Affects Versions: 4.10.0
> Reporter: Bruno Meseguer
> Assignee: Otavio Rodolfo Piske
> Priority: Major
> Fix For: 4.12.0
>
>
> When a Camel route uses the LangChain4J-tools component, it calls the LLM,
> providing metadata about the tools (tool routes) available the LLM can use.
> The LLM computes the request and decides if a tool call is necessary or not.
> If the LLM performs a tool call, Camel executes the tool and returns the
> result to the LLM.
> However, the current implementation does not provide the Tools metadata
> (tools available) when returning the tool result.
> The consequence of Camel not including Tools metadata when returning the tool
> response is that the LLM understands there are no more Tools available, and
> concludes that subsequent tool calls are not allowed, forcing the LLM to
> compose a final response.
> The expected behaviour from Camel is to always provide a full history of tool
> calls and results, including the metadata of available tools the LLM can use
> at all times.
> Let's assume Camel asks the LLM the following question:
> * "what is the weather in London?"
> Camel calls the LLM and provides metadata listing the tools available to the
> LLM. In this example, it would provide:
> * Tool to find the geo-coordinates for a given city
> * Tool to obtain weather information for a given longitude and latitude
> The LLM needs to first obtain from Camel the geo-coordinates for London, and
> in a subsequent call, invoke the second tool to obtain the weather passing
> the geo-coordinates obtained in the first call.
> When Camel returns the result of the geo-coordinates tool call, the current
> implementation is missing to provide tools metadata. The sample below shows
> all the data Camel needs to provide to allow the LLM to call a second time:
> {code:java}
> Request:
> - method: POST
> - url: http://localhost:11434/api/chat
> - headers: [Accept: application/json], [Content-Type: application/json],
> [User-Agent: Apache Camel], [content-length: 2257]
