Design tools for agents — function/tool definitions, MCP (Model Context Protocol) servers, tool routing when there are many tools, structured outputs, and the rules of thumb that prevent tool selection failures. Use whenever the user is adding tools/functions to an agent, integrating external systems, building or consuming MCP servers, hitting "the agent picks the wrong tool" failures, designing function signatures, choosing between MCP and direct function calling, or wondering how many tools is too many.
