TDQS

A4.2/5.0

Behavior4/5

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

注解没有提供异步等待或返回 job_id 的信息，描述补充了“最多等待 240 秒”和“未完成时返回 job_id 和下一步查询动作”，这增加了对异步行为的透明度和后续调用的指导，且与注解（readOnlyHint=false）无矛盾。

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

描述仅一句话，直接说明了核心动作和关键行为，没有冗余信息，信息密度高且易于理解。

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

工具是异步提交任务，有输出 schema（可能包含 job_id 等），描述提供了必要的等待时间和返回内容，足以让 agent 知道如何发起调用并确定后续动作；对于简单的一参数工具，描述足够完整。

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

唯一的参数 aweme_id 在 schema 中已有详细说明（包括来源和排除项），描述本身没有额外补充参数语义，schema 覆盖 100%，基线为 3 是合适的。

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

描述明确说“根据抖音 aweme_id 提交视频口播转文字任务”，动词“提交”和资源“视频口播转文字任务”都很具体，且和兄弟工具 `douyin_submit_video_speech_text_by_video_url` 在用途上形成清晰区分（按 ID 提交 vs 按 URL 提交）。

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

描述了提交后的行为（等待 240 秒、返回 job_id 和下一步查询动作），间接暗示了后续应使用 `douyin_get_video_speech_text_job` 查询状态，但没有明确说“当你有 aweme_id 时使用此工具，而不是按 URL 提交”，不过名字已经足够区分，用户只需根据输入类型选择。

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