gpt_image_result

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

在没有注释的情况下，描述承担了行为透明度的全部责任。它准确说明了这是一个查询操作而非生成操作，并指明返回内容包含可能出现的失败原因（failReason），但未明确说明查询是否是幂等的或可能多次调用产生的影响（如是否消耗配额），因此扣1分。

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?

描述非常简洁，仅两句话，第一句说明功能，第二句给出使用条件，无冗余内容。但第二句使用了中文句号，结构合理，信息密度高，完全符合前端加载原则。

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?

考虑到工具只有一个参数，且有输出模式，描述完整覆盖了使用场景和返回的关键字段（status/imagePaths/failReason），无需额外补充，对于其复杂度来说非常完整。

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?

参数描述覆盖率为0%，描述承担了完全责任。它提到了taskId的上下文（来自gpt_image_generate超时后返回），但未在描述中显式说明task_id参数的具体格式或限制（如字符串长度）。由于只有一个参数且上下文已暗示，额外信息需求不高，但仍有微小提升空间。

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?

描述清晰地声明了工具用于查询GPT图片生成任务的结果，并明确列出了返回内容（status/imagePaths/failReason），动词“查询”和资源“GPT图片生成任务结果”非常具体，且与同类工具（如doubao_image_pro_result）有区分。

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?

描述明确给出了使用条件：仅在gpt_image_generate超时返回taskId后使用。这直接告诉代理何时应该使用此工具，以及避免在任务未超时或没有taskId时调用，提供了清晰的上下文和排除条件。

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