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

无注释，描述需承担行为透明责任。提到了'相同答案不会重复提交'（幂等性）和'不支持代答权限审批'（权限限制），但未说明副作用、所需权限、错误行为等关键信息。对于回答操作，缺少对变更的透明披露。

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?

三句话，简洁且信息密集，没有冗余。但结构上可考虑将参数用法与行为限制分开，但总体可读。

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?

对于简单工具，描述提供了基本功能、参数用法和限制，但缺少参数alaias和questionId的说明，也没有输出或错误信息。在无注释和输出schema的情况下，信息尚不完整，但基本可用。

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覆盖率为0%，描述必须补偿。它解释了'selected'和'custom'的用法（精确标签和文字回答），但未说明'alias'和'questionId'的含义。虽然部分参数被解释，但关键参数仍不清晰。

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?

描述明确说明工具用于'回答指定的 DSH 普通问题'，动词和资源清晰。但'DSH 普通问题'含义模糊，且未与同级工具（如 talk_questions、talk_read）明确区分，不过整体目的明确。

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?

仅提到'不支持代答权限审批'，这是一个限制条件，但没有说明何时使用该工具、何时不使用，也未提及替代方案。缺乏使用场景指导。

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