Behavior3/5

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

No annotations are provided, so the description carries the full disclosure burden. It specifies the return value format ('JSON string of health status') and the external dependencies checked, but omits behavioral traits like whether results are cached, if the check makes live HTTP requests, rate limiting, or safety properties (read-only nature).

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?

The description is appropriately sized with two distinct sections: the purpose statement naming specific data sources, and a clear 'Returns' declaration. Every sentence earns its place with zero redundancy or tautology.

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 zero-parameter simplicity and existence of an output schema (per context signals), the description is reasonably complete: it identifies the scope (which specific sources are checked) and return format. Minor gaps remain regarding error handling semantics and cache duration, but sufficient for a utility health endpoint.

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

Parameters4/5

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

The tool has zero parameters and schema coverage is 100% (trivially). Per the rubric, zero parameters warrants a baseline score of 4. The description correctly focuses on behavior rather than inventing parameter documentation.

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 uses a specific verb ('检查/check') with specific resources ('论文下载服务各数据源的可用性/availability of paper download service data sources'), explicitly listing the monitored sources (Unpaywall, arXiv, Sci-Hub mirrors). This clearly distinguishes it from sibling tools like paper_download or paper_search which perform operations on papers rather than checking service health.

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?

While the purpose is clear, there is no explicit guidance on when to use this tool versus alternatives (e.g., 'call before batch downloads to verify availability'). The usage is implied by the health-check nature, but lacks explicit when/when-not recommendations or prerequisites.

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