mcp builder: agent skill — from anthropics/skills.
Best for taking a tool or API you already use and exposing it via MCP so Claude (or any MCP-aware agent) can call it directly. Handles the MCP protocol surface — tools, resources, prompts — without hand-writing the schema. Strongest when the underlying tool already has a clean API. Weakest when you need to build the underlying tool first; do that separately, then wrap.
把你已经在用的工具或 API 通过 MCP 暴露出来、让 Claude 或任意支持 MCP 的 agent 直接调用时，它最有用。直接处理 MCP 协议表面——tools / resources / prompts——不用手写 schema。底层工具已经有干净 API 时最强。底层工具本身还要先造的场景下不合适，先单独造完工具再用它包装。
