edubase_post_exam_certificates_user_download

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

The description discloses the idempotent-like behavior of returning an existing link, but this contradicts the annotation 'idempotentHint: false'. Also, it does not disclose other important behaviors like link expiration or access permissions. This serious contradiction earns a score of 1.

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 concise with two sentences and no extraneous information. However, it could be slightly more structured, but overall it is efficient.

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?

The description lacks mention of the output format (the download link) despite an output schema existing. The tool is simple, but the gap in describing the response reduces completeness. It is adequate but not comprehensive.

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?

The input schema already fully describes both parameters (exam, user) with schema coverage at 100%. The description adds no additional semantic information about the parameters, so baseline 3 is appropriate.

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 the verb 'Generate download link' and the resource 'latest user exam certificate', and adds the behavior of returning an existing link. This distinguishes it from sibling tools like 'edubase_get_exam_certificates_user' which likely retrieves certificate info without a download link.

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?

There is no guidance on when to use this tool versus alternatives. For example, it does not mention when to use 'edubase_get_exam_certificates_user' instead, nor any prerequisites or context for generating a link.

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