Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
categoryYes分类(可选)
Behavior1/5

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

No annotations are provided, and the description does not disclose any behavioral traits such as read-only nature, rate limits, error behavior, or required authentication. Only pricing and API URL are given, which is insufficient for behavioral understanding.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short, which is efficient, but it mixes pricing and API URL with the purpose, lacking a clean structure. The information is dense but not well-organized for an agent to parse.

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

Completeness2/5

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

Given the lack of output schema and minimal description, the agent cannot determine the response format or additional context needed for effective use. With 1 parameter, the tool is underspecified.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description for 'category' is '分类(可选)' (optional) but the schema marks it as required, creating confusion. The description does not elaborate on possible category values or behavior. With 100% schema coverage, the description adds no value beyond the minimal schema description.

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 explicitly states '全球新闻' (global news) and includes a [News] prefix, clearly indicating it fetches news. Sibling tool 'news_crypto' suggests distinction, so purpose is clear, though exact scope of 'global' could be more specific.

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?

No guidance on when to use this tool vs alternatives like news_crypto. No conditions for use or when to avoid are provided.

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