get_site

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations已声明readOnlyHint=true和destructiveHint=false，表明这是一个安全读操作。描述没有添加额外的行为细节（如权限要求、副作用），也没有与注释矛盾，符合有注释时的基线水平。

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

描述非常简短，没有冗余文字，但由于缺少动词，结构上不完整。它更像一个名词短语而非功能说明，虽然简洁但未能有效传达工具用途。

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

对于如此简单的读操作，描述仅提及输出包含属性和权限级别，未说明具体返回结构或使用场景。由于目的模糊且没有输出schema，整体上下文不够完整，无法让agent确定调用后的预期结果。

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

输入schema对site和account两个参数有100%覆盖，详细说明了属性和账号的格式及注意事项。描述本身未添加参数信息，但schema已足够充分，因此给予基线3分。

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

描述是名词短语'One property and the permission level this account holds on it.'，缺少明确的动词（如'Retrieves'或'Gets'），未直接说明工具执行的操作。虽然从工具名推测是获取站点，但描述本身没有清晰表达目的，也未与兄弟工具区分。

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

描述未提供任何关于何时使用此工具或何时选择替代工具（如list_sites、get_verification_token）的指导。尽管site参数的描述中提及调用list_sites，但这仅涉及参数值，而非工具选择的情景。

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
