TDQS

A3.8/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds genuinely useful behavior beyond that: results are restricted to first-level comments only (not replies) and paging is driven by page_token. It stops short of saying what a terminal/empty page looks like, but the schema's page_token text fills much of that.

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?

A single tight sentence that front-loads the action and resource, then lists input forms and pagination support. No filler and nothing redundant.

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?

An output schema exists, so return values need no explanation, and the two parameters are fully documented. What is missing is only the sibling routing (URL vs aweme_id entry) and pagination termination behavior, both minor for a simple read tool.

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 parameter descriptions are extremely detailed (opaque token semantics, no modification/truncation, no cross-video reuse). The description only restates the accepted URL forms and that pagination exists, adding little beyond the schema, so the baseline 3 applies.

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

Purpose4/5

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

States a specific verb+resource: fetch the top-level comment list ('一级评论列表') of a Douyin video, and enumerates the accepted input forms (page URL, short link, share text). The scope word '一级' distinguishes it from the sibling replies tool, but the description never names or contrasts douyin_get_video_comments_by_aweme_id, leaving the URL-vs-ID choice implicit.

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?

Usage context is implied by the accepted input forms, but there is no explicit when-to-use / when-not-to-use statement and no routing to the aweme_id sibling. The valuable guidance ('已知 aweme_id 时优先使用 ID 入口', don't pass play URLs or profile links) lives in the schema parameter description, not the tool description.

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