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

注解未提供任何安全或只读提示，因此描述需承担全部行为披露责任。描述仅说明'列出全部長期記憶'，没有说明操作是只读的、无副作用，也没有提及性能、分页、排序或错误处理。对于简单的列表工具，行为透明度严重不足。

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?

描述仅一句话，无冗余信息，目的明确且高效。虽然简短但信息密度高，没有浪费字节，符合简洁性要求。

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?

工具无参数、无输出模式，复杂度低。但描述仅简单声明列出全部长期记忆，未提及返回格式、内存条目的结构、是否分页等。考虑到兄弟姐妹工具的存在，输出可能类似，但描述未明确说明。对于简单工具，缺少数个关键上下文细节，但整体仍可用，故评分3。

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?

工具无参数，因此基线为4。描述没有重复参数信息（也没有参数可描述），且无必要添加额外语义。输入模式覆盖100%，无需补偿，符合基线标准。

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?

描述包含具体动词'列出'和资源'長期記憶'，明确表示这是列出所有长期记忆的操作。结合工具名和兄弟工具（memory_search、memory_add），可以清楚区分这是列表操作而非搜索或添加，虽然没有详细说明返回结构，但目的明确。扣除1分是因为描述简短，未涉及任何范围限定或返回值细节，但基本符合清晰标准。

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?

描述没有提供任何使用时机或替代方案说明。没有提及何时用memory_list而不是memory_search，也没有说明是否适合查看全部记忆或需要过滤场景。隐含的使用场景是'列出全部'，但未明确表达，也没有排除条件。

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