Agent Tool Builder

About Agent Tool Builder

Tools are how AI agents interact with the world. A well-designed tool is the difference between an agent that works and one that hallucinates, fails silently, or costs 10x more tokens than necessary. This skill covers tool design from schema to error handling: JSON Schema best practices, description writing that actually helps the LLM, validation, and the emerging MCP standard that's becoming the lingua franca for AI tools. Key insight: tool descriptions are more important than tool implementations.

工具是AI代理与世界交互的方式。设计良好的工具决定了代理是能正常工作，还是会出现幻觉、静默失败，或比必要情况多消耗10倍代币。本技能涵盖从模式（schema）到错误处理的工具设计：包括JSON Schema最佳实践、真正能帮助LLM的描述撰写、验证，以及正在成为AI工具通用语的MCP新标准。关键见解：工具描述比工具实现更重要。
