Training Small Language Models for Transferable Tool Selection

A new arXiv paper addresses how LLM agents choose the right tool when they have access to more than ten thousand tools. According to the snippet, selecting tools for complex multi-step instructions is a central bottleneck, because tool descriptions cannot all fit in context and relevance-based retrievers only rank tools without knowing which ones are actually needed. The paper notes that recent work has used proprietary commercial LLMs such as Claude or ChatGPT to drive a retriever by decomposing tasks. The snippet is cut off, so the paper's specific method and results are not described here.

AI-assisted summary based on the listed source.

As LLM agents operate over corpora of more than ten thousand tools, selecting the right tool for a complex multi-step user instruction becomes a central bottleneck. Tool descriptions cannot all fit in context, and relevance-based retrievers only rank tools without knowing which are actually needed. Recent work...

Builders of AI agents that connect to large tool libraries may care about this problem, since tool selection affects which capabilities an agent can reliably use. The work focuses on training small language models, which could matter for teams that want to avoid relying on proprietary commercial models for this step. Readers should look for the paper's reported results and whether the approach transfers across tool sets.
