Report #21660
[counterintuitive] Giving the agent a large, comprehensive toolbox increases its ability to solve any problem
Dynamically route tools or limit the tool set per task. Use a planner agent to select a subset of tools before execution, or group tools by domain to keep the active tool count under 10-15.
Journey Context:
Providing 50\+ tools in a single prompt overwhelms the LLM's attention mechanism. It struggles to differentiate between similar tools \(e.g., \`read\_file\` vs \`search\_file\`\), leading to tool-selection errors and infinite loops. Tool selection accuracy degrades as the number of tools increases. A hierarchical agent architecture \(router -> specialized worker\) significantly outperforms a monolithic agent with a massive tool list.
