TDQS

A4.1/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds valuable behavioral details: maximum 240-second wait per call and that it does not trigger reprocessing. This goes beyond the annotations and informs the agent of polling behavior and side-effect-free nature.

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

Conciseness4/5

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

The description is a single sentence but packs in the purpose, usage context, and key constraints. It is front-loaded with the core action and avoids redundancy. Could be split for readability but is efficient overall.

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?

Given the presence of an output schema and the simplicity of a status-polling tool, the description covers what the tool does, when to use it, and key behavioral limits. No critical missing information for correct invocation, though it omits any note about invalid job_id handling, which is minor given the schema guidance.

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?

Schema description coverage is 100% and the job_id parameter is already fully explained in the schema (use user-provided or submit tool's job_id, not aweme_id or links). The description repeats this but adds no new meaning beyond the schema, so baseline 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 clearly states the tool queries the status of a Douyin video speech-to-text task, with specific verb '查询' and resource '任务状态'. This distinguishes it from sibling tools like user info or video detail fetchers, and from the submit tools that create the task.

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?

The description instructs to use a valid job_id from the user or the submit tool, and explicitly says to use it for continuing unfinished tasks. It also warns against resubmitting tasks, which guides the agent toward correct workflow integration with the submit siblings.

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