Describe the feature you'd like
Tool definitions can often make a up a large portion of token usage and important context for LLM inference, but dd-trace-js doesn't currently instrument this despite it being a part of the OTEL gen_ai specification (gen_ai.tool.definitions). It's also published by many of the frameworks supported by dd-trace-js including the Vercel AI SDK.ai (ai.prompt.tools).
Is your feature request related to a problem?
Tool definitions are not published by the LLM observability plugin for any framework.
Describe alternatives you've considered
These can be manually included in metadata, but this doesn't accurately represent their role.
