download_openalex

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

The description discloses that the tool typically returns an error message because OpenAlex relies on extracted pdf_url, which is a key behavioral trait. However, it does not explain what happens on success or the actual download mechanism. With no annotations, the description carries the full burden but still leaves ambiguity.

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?

The description is very short and front-loaded with the main action. It lists args and return in a clear structure with no extraneous information. Every sentence earns its place.

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?

Given the tool's simplicity (2 parameters, no nested objects), the description covers the basic purpose and parameters. However, it lacks information about the success return value (only mentions error message) and does not describe edge cases or behavior when the PDF is available. The output schema exists but the description only mentions a string return, which is consistent but incomplete for a download tool.

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?

Schema coverage is 0%, so the description must provide parameter meaning. It explains paper_id as 'OpenAlex paper ID' and save_path with default directory. This adds value beyond the raw schema, though it could specify format or constraints.

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 clearly states 'Download PDF for a paper from OpenAlex', specifying the verb and resource. It distinguishes from other download tools by naming OpenAlex, though it could further differentiate from other similar OpenAlex tools like 'read_openalex_paper'.

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?

The description provides no guidance on when to use this tool versus the many sibling download tools (e.g., download_arxiv, download_pubmed). There is no mention of prerequisites, alternatives, or conditions for use.

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