TDQS

A4.5/5.0

Behavior4/5

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

Annotations already indicate readOnlyHint and openWorldHint, so no mutation risk needs explanation. The description adds value by clarifying that only first-level comments are returned and that page_token pagination is supported, which are behavioral traits not captured by the 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 front-loaded sentence that communicates the core purpose and pagination capability with no filler. Every word is informative, and detailed parameter nuances are appropriately left to the schema.

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

Completeness5/5

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

For a two-parameter read-only tool with an output schema present, the description plus detailed schema fully covers what an agent needs: accepted URL forms, pagination semantics, and the top-level comment scope. Return-value details are already handled by the output schema.

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%, so the schema fully documents both parameters. The description's reference to supported link formats and pagination aligns with the schema but does not add substantial meaning beyond it, matching the baseline of 3.

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 ('获取'/'get'), resource ('一级评论列表'/'first-level comment list'), and input method (video URL/short link/share text). It distinguishes from sibling tools by making the top-level scope explicit and by noting the URL-based entry point, which contrasts with the aweme_id-based sibling.

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

Usage Guidelines5/5

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

The description and url schema condition together give explicit usage guidance: accept video page URLs, short links, or share text; explicitly exclude video.play_url playback URLs and user profile links; and recommend the aweme_id entry when the ID is known. This clearly routes the agent to the correct input mode and sibling tool.

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