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

With no annotations, the description carries the full behavioral burden. It says it returns download links but doesn't state whether links expire, whether the operation is safe/read-only, what happens if the request is still processing, or what form the response takes. For a tool with zero annotation coverage this is a substantial gap.

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?

A single efficient sentence with the purpose front-loaded and no wasted words. It is well-sized, though the brevity comes at the cost of detail elsewhere.

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 retrieval tool with no annotations and no output schema, the description should at least characterize the returned links (expiry, quantity, format) and the prerequisite request lifecycle. It notes only that links are returned, leaving key operational context missing.

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 description coverage is 0% and the description never mentions 'request_id' explicitly. The only hint is the phrase 'produced by a request,' which leaves the parameter's origin, format, and how to obtain it undocumented in both schema and description.

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?

States a specific verb and resource: 'Returns the download links for the documents produced by a request.' This is clear enough to distinguish from most siblings, but it never names the related tools (get_docuengine_request_status, the document-generating docuengine_* calls), so an agent must infer the workflow linkage on its own.

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 on when to call this versus alternatives. It doesn't explain the expected flow (generate document → poll status → fetch links) or that a prior request must exist, which is essential context given the large sibling set of docuengine_* tools.

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