memory_update

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

描述提到更新内容会经过脱敏与评价门，揭示了一个重要的处理流程，但未说明失败行为（如门拒绝时返回什么）、权限要求、可逆性或副作用。由于无注解，描述承担全部责任，但此处提供的信息有限，仅部分披露了行为。

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?

一句话完成，无冗余，动作前置，括号补充关键流程约束。紧凑且信息优先，符合高效结构要求。

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?

无输出schema，无注解，且为变更操作，但描述未说明返回内容、错误处理、副作用（如修改是否不可逆），也未说明通过门失败时的行为。对于调用者而言，信息不足以做出正确调用决策，完整性不足。

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0%，参数名称和类型是唯一信息。描述未对memory_id或new_content增加任何额外语义，如格式、长度限制、示例或注意事项。描述仅重复了'正文'概念，对参数理解帮助有限。

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?

描述明确给出具体动作'更新'和资源'记忆的正文'，并附带脱敏与评价门的处理提示，使工具用途清晰且与其他记忆操作（如添加、删除）区分开来。即使未命名兄弟工具，名称和描述已足够明确。

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?

未提供任何使用时机或与其他工具的对比。没有说明何时应使用更新而非添加或删除，也没有提及前置条件（如记忆必须存在）。仅凭工具名称和描述推断用途，缺乏明确指导。

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