  5. First observed

TDQS

A3.8/5.0
Behavior2/5

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

Annotations already declare readOnlyHint=true, and the description adds no further behavioral context (rate limits, auth, data freshness, or meaning of openWorldHint). It simply restates the purpose without any extra disclosure, so it adds little beyond the annotation.

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 short sentence that directly states purpose and usage condition with no filler. Efficient and front-loaded, ideal for a simple tool.

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?

For a 1-parameter read-only tool with an output schema, the description combined with the schema covers essentials. Missing explicit error handling and a direct pointer to the URL-based sibling, but those are inferable from the sibling names and schema guardrails.

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?

The schema description for user_id is thorough, covering format, sourcing, and negative conditions. With 100% schema coverage, the tool description needs to add nothing extra, so baseline 3 applies.

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?

States a specific verb and resource: 'get user info' by WeChat Channels user ID. Clearly distinguishes from URL-based sibling (wechat_get_user_info_by_url) and from video-listing tools by explicitly naming the lookup key.

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 says to use directly when the user provided a valid user_id, and the schema description elaborates where to source the ID otherwise and enforces the v2_...@finder format. It provides a clear condition but stops short of explicitly naming alternatives like the URL-based tool.

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