import_json

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

无注释，描述未披露行为细节，如是否验证数据、是否覆盖现有故事、是否原子操作、错误处理等。对于写入类工具，缺乏这些信息会增加风险。

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，完全简洁，无冗余信息，直接传达核心功能。

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?

作为导入工具，描述未说明返回结果、验证机制或对现有数据的影响，无输出模式，且无注释，信息不足以让代理安全调用。

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?

模式覆盖率100%，描述中简要列出了stories的可选字段（title必填等），但未超出模式已有信息，基线3分合适。

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?

说明为从JSON批量导入故事，动词明确（导入），资源明确（故事），且提到与CLI同构，有助于理解。能区别于兄弟姐妹工具如scan_stories、validate等。

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?

没有提供任何何时使用或何时不使用的指导，也未提及替代工具。描述仅说明功能，未给出上下文场景。

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