Your AI Agent Doesn’t Need 100 Tools. It Needs the Right One.
A new paper titled "ToolChoiceConfusion: Causal Minimal Tool Filtering for Reliable LLM Agents" by R.S. Babu and L.G. Iyer proposes a solution to a common problem in LLM agents: selecting the correct tool from a large set. The paper argues that current methods focus on semantic relevance, which can lead to agents choosing plausible but premature or dangerous tools. The proposed Causal Minimal Tool Filtering (CMTF) method uses tool preconditions and effects to build a dependency graph and expose only the necessary next tool on the causal path to the goal state, simplifying decision-making for the LLM.
