TDQS

A4/5.0

Behavior4/5

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

Annotations indicate readOnlyHint=false and idempotentHint=false, confirming a non-idempotent mutation. The description adds specific behavioral context: it waits up to 240 seconds and returns a job reference if incomplete, which is useful for an agent deciding whether to call this synchronously or poll later. No contradiction with annotations.

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?

The description is a single, well-structured sentence that front-loads the primary action and then clearly states the wait/timeout behavior. Every part adds value and there is no redundancy or filler.

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?

The tool has an output schema, so return values do not need to be explained. The description covers the essential flow (submit, wait, get job_id if not done) and implicitly communicates asynchronous behavior. It does not explicitly mention what happens on immediate completion, but that is left to the output schema. Overall, it is sufficiently complete for an agent to invoke correctly.

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?

There is only one parameter (video_url) and its schema description is highly detailed (100% coverage), specifying acceptable URL forms and exclusions. The tool description adds no additional parameter meaning beyond what the schema already provides, so the baseline of 3 is appropriate.

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?

The description states a specific verb ('提交' meaning submit), a concrete resource (video speech-to-text task), and explains the follow-up behavior (wait up to 240 seconds, return job_id if incomplete). It clearly distinguishes this submission tool from query tools like douyin_get_video_speech_text_job.

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

Usage Guidelines3/5

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

The description mentions waiting and returning job_id with a next query action, which implies using a query tool, but it does not explicitly differentiate when to use this URL-based submission vs the aweme_id-based alternative (douyin_submit_video_speech_text_by_aweme_id). The parameter schema separately recommends the ID entry, but that is not in the tool description. Guidance is implied but not explicit.

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