Introducing advanced tool use on the Claude Developer Platform

This post introduces three new features for the Claude Developer Platform that enhance AI agent tool use: Tool Search Tool, Programmatic Tool Calling, and Tool Use Examples. Tool Search Tool allows Claude to dynamically discover and load tools from large libraries on-demand, drastically reducing initial token consumption and improving tool selection accuracy. Programmatic Tool Calling enables Claude to orchestrate multi-step workflows using code execution, keeping intermediate results out of the model's context and reducing latency and errors. Tool Use Examples provide a standardized way for agents to learn effective tool usage patterns beyond schema definitions. These features collectively enable more powerful, efficient, and scalable AI agents by addressing limitations in context window management, inference overhead, and tool discovery.
