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

With no annotations provided, the description carries the full burden. It successfully discloses the return format (JSON string with status and statistics) and file output behavior (PDF), but omits critical safety information like whether existing files are overwritten or error handling behavior.

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

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

Uses a clear docstring structure (Args/Returns) that frontloads the purpose statement and organizes supplementary information efficiently. The Chinese text is appropriately concise with zero redundant sentences.

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

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

For a 2-parameter tool with simple primitives, the description adequately covers inputs and acknowledges the output schema (JSON result). It appropriately delegates detailed return structure documentation to the output schema itself.

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

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

Given 0% schema description coverage, the description compensates effectively: it explains 'dois' is a list with concrete examples, and clarifies 'output_dir' is a directory path with default value (current directory). It could improve by detailing DOI format validation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific action verb (批量下载/batch download) and clear resource (多篇论文 PDF/multiple paper PDFs), immediately distinguishing it from the singular 'paper_download' sibling tool through the emphasis on batch processing.

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

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

While the Args section implies usage through the plural 'dois' parameter and_examples, there is no explicit guidance on when to choose this over 'paper_download' (singular) or prerequisites like valid DOI format requirements.

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