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

The readOnlyHint=true annotation already covers safety, and the description adds the 'current user's' authorization scope, which is useful. It does not disclose polling/readiness semantics (e.g., that the task may still be processing or the result absent), but this is not a contradiction with annotations.

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 sentence with no filler; the action and resource are front-loaded. Nothing extraneous is included.

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?

With one well-described parameter, an output schema, and a read-only annotation, the definition is largely adequate. The main gap is the lack of guidance distinguishing it from list_pdf_tasks, but complexity is low enough that an agent can call it correctly with a task_id.

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 100% and the task_id property is described as 'task identifier returned by a PDF tool.' The tool description adds no parameter-level meaning beyond this, so it meets the baseline without enhancing it.

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 names a specific action ('Get'), a resource ('the current user's PDF task status and result'), and a singular task scope. It is clear but does not explicitly contrast itself with list_pdf_tasks, so an agent must infer that this is the single-task retrieval counterpart.

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 statement about when to call this tool rather than list_pdf_tasks or when to poll. The only contextual clue is the schema's task_id description ('returned by a PDF tool'), which lives outside the description, so the description itself offers no usage routing.

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