TDQS

A4.2/5.0

Behavior4/5

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

Annotations already mark the operation read-only, and the description adds the behavioral detail that only top-level comments are returned and that page_token pagination is supported. The input schema further discloses the article-link special case and opaque token rules, so the behavioral picture is clear.

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?

One compact sentence conveys the operation, input forms, comment level, and pagination with no filler. It is front-loaded and easy to scan.

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 read-only annotation and a rich input schema plus output schema, the short description is sufficient for an agent to call the tool correctly. It could add an explicit pointer to the by-post_id sibling for agents that already have an ID, but the naming and schema cover most of that gap.

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 in the schema are unusually detailed (post_url accepted forms, sort_type consistency, page_token opacity). The top-level description adds no parameter-level meaning beyond restating URL/share-text inputs, 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 states a specific verb ('获取'), a clear resource ('微博帖子一级评论'), and the accepted input forms ('链接、短链接或分享文案'), plus pagination support. This distinguishes it from the by-post-id sibling and reply tool by name and by the top-level comments scope.

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 makes the intended input context explicit: post URLs, short links, or share texts, and specifies '一级评论' so agents know it is not for nested replies. It does not name the by-post-id alternative or explicitly say when not to use it, but the URL-based scope and sibling naming provide clear context.

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