TDQS

C2.9/5.0

Behavior2/5

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds nothing behavioral beyond the bare fetch intent — no auth requirements, rate limits, or data freshness context — so it contributes essentially no value beyond structured fields.

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?

A single, front-loaded sentence that wastes no words and states the fetch intent immediately. It is efficient, though its extreme brevity is achieved partly by omitting useful guidance rather than by tight writing alone.

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

Completeness3/5

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 not be explained, and annotations cover the read-only/open-world nature. For a single-parameter read tool this is close to adequate, but the absence of any usage or behavioral context leaves a gap for an agent choosing between the user_id and profile_url entry points.

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 coverage is 100% and the single user_id parameter is documented in exceptional detail (accepted formats, sources, and what not to pass). The description adds no meaning beyond what the schema already provides, 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?

The description states a specific verb (获取) and resource (单个小红书用户信息) keyed by user_id, so the agent knows exactly what it fetches. It does not explicitly contrast itself with the sibling xhs_get_user_info_by_profile_url, though the '根据 user_id' qualifier implicitly separates the two entry points.

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

Usage Guidelines2/5

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

The description text contains no when-to-use or when-not-to-use guidance. The only routing hint (use the profile_url entry when you lack a user_id) lives in the schema's parameter description, not in the description itself, so the description provides no selection guidance to the agent.

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