Anthropic is launching advanced tool use capabilities on the Claude Developer Platform, enabling agents to discover and load tools on-demand rather than stuffing all definitions into context upfront. New features include tool libraries for on-demand loading, code execution for orchestration logic (loops, conditionals), and few-shot examples to teach correct tool usage patterns beyond JSON schema definitions. This directly addresses scalability bottlenecks for agents working across large MCP server ecosystems.
