基于对工具定义和协议合规性的自动分析。

~268token 数（工具定义）
~726 B典型响应大小
对注意力的影响极小（占 128k 上下文窗口的 0.21%）
这是每次将服务器的工具加载到模型上下文窗口时所消耗的大致 token 数。数值越高，可用于其他任务的注意力就越少。

🟢check_citation(url, claim)
Fetch a URL and report whether it exists, and whether the source names the same entity as the claim you attach to it. These are two different questions and conflating them is the failure this exists to catch: a URL can return 200 and describe a different gene entirely. No account needed, nothing is stored about you.

}🟢verdict_meanings
