set_group_name

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

无 annotations，描述需承担全部行为披露责任。它说明了操作会改变整个群的状态且所有人可见，这是有价值的副作用提示；但未说明所需权限、是否可逆、调用后的响应或错误情况，披露不够完整。

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?

两句话，共十余字，前置核心动作，没有冗余内容，非常紧凑。

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?

这是一个无 annotations、无 output schema 的变更型工具，描述只点明了全局可见的副作用，但未覆盖权限要求、可逆性、失败情形等调用者需要的信息，完整性仅达最低可用水平。

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?

schema 描述覆盖率为 100%，group_id 和 group_name 的语义已在 schema 中说明。描述仅重复「改群名」，没有补充参数格式、约束或使用注意事项，因此属于基线水平。

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?

明确使用了具体动词「改」和资源「群名」，与同级工具如 set_group_card、set_group_admin 等能清晰区分。作用对象和操作类型一目了然。

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?

描述没有说明何时应使用本工具、何时应改用其他工具，也没有提及前置条件（如权限要求）。只有一句效果说明，缺少使用场景指引。

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