download_openalex

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

With no annotations, the description carries full burden. It hints at indirect downloads but does not fully explain behavior, such as what the tool actually does (attempts download? returns URL?). The return is only described as an error message, which is misleading for a download tool.

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 short but includes a one-line purpose and docstring-style args/returns. It is reasonably concise, though the return line is confusing and could be better structured.

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 complexity of many sibling tools, the description is incomplete. It fails to explain the tool's role in the ecosystem, what happens on success, or the actual output beyond an error message. The presence of an output schema (not shown) might mitigate, but the description alone is insufficient.

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 compensates by defining paper_id as 'OpenAlex paper ID' and save_path as 'Directory to save the PDF'. This adds basic meaning beyond the schema, but lacks format details for paper_id and usage of default.

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, resource, and source. However, it mentions reliance on pdf_url rather than direct downloads, which introduces ambiguity about the actual function.

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?

No guidance is provided on when to use this tool over the many sibling download sources. The description does not differentiate OpenAlex from others or specify prerequisites.

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