Save valuable user details, commitments, preferences, and shared experiences into long-term memory, assigning salience (1-5) to control what gets retained.
把一件事写进 PASM 长期记忆。值得记住的用户信息、承诺、偏好、共同经历都应该写进来。salience 越高越不容易被淘汰（1-5，重要的事用 4-5）。

v0.2.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
无注释，描述需承担全部责任。它披露了salience对淘汰概率的影响（'salience 越高越不容易被淘汰'），这是有价值的行为信息。但未说明写入是否覆盖、权限要求或返回内容，行为披露不全面。
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?
两句话简洁明了，第一句定义核心功能，第二句补充内容类型和salience指导，无冗余，结构紧凑。
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?
对于写入工具，描述提供了内容建议和salience行为，schema覆盖主要参数。虽无输出schema，但未解释写入后的结果或与兄弟工具的区分，稍有不足，但整体上足够使用。
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83%，大多数参数已有描述。描述额外补充了salience的行为含义（影响淘汰）以及内容类型建议，对参数语义有增值，但未完全覆盖所有参数。
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?
描述明确说明该工具用于将事件写入PASM长期记忆，动词和对象清晰，并列举了应记录的内容类型（用户信息、承诺、偏好、共同经历），与兄弟工具pasm_save等区分开，尽管未直接命名，但语义明确。
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?
描述指出'值得记住的用户信息、承诺、偏好、共同经历都应该写进来'，提供了清晰的使用时机。但未明确说明何时不使用或与其他工具（如pasm_save）的替代关系，缺少排除性指导。
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
