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

The description discloses key behavioral traits beyond annotations: it reuses existing valid links. Annotations have readOnlyHint=false and idempotentHint=false, yet the description implies some idempotency by returning existing links. This could be slightly misleading but the description adds value by explaining the caching 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?

The description is concise: two sentences, no wasted words, and the purpose is front-loaded. Every sentence adds value.

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 two simple string parameters, an output schema (exists), and annotations, the description covers the main behavior. It lacks details on prerequisites (e.g., certificate existence) or error handling, but is largely sufficient.

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 provides descriptions for both parameters ('exam identification string', 'user identification string'), achieving 100% coverage. The description does not add further meaning beyond these.

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 tool's purpose: 'Generate download link for the latest user exam certificate.' It specifies the verb (generate) and resource (download link for certificate), and distinguishes from sibling tools like edubase_get_exam_certificates_user which likely retrieves certificate info rather than generating a 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?

The description provides context on when to use the tool (to get a download link for the user's latest exam certificate) and describes behavior for existing links ('If a previous valid link exists, it will be returned instead'). However, it does not explicitly contrast with alternatives or state when not to use this tool.

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