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

Annotations already cover the safety profile (readOnlyHint=true, openWorldHint=false), and the description adds real value by scoping what is deliberately absent: no document body and no signing link. That negative scoping prevents an agent from calling it expecting file content, though it says nothing about error behavior for an unknown id.

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?

One sentence, front-loaded with the resource and scope, then enumerating returned fields and ending with the most useful exclusion. Nothing is wasted.

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 no output schema, the description carries the return-value burden and does well on signer-level fields, but omits other likely members (overall request status, expiration, subject/message, created timestamps) that an agent would need to plan around. Adequate but not exhaustive.

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 single request_id parameter is documented as a uuid sourced from list_signature_requests, so the schema does the heavy lifting. The description adds no format, provenance, or validity detail beyond that; baseline 3 applies.

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 states precisely what the tool returns for a single signature request: signers, signing order, per-signer status values, timestamps, and the hosting page. The word 'One' implicitly contrasts with list_signature_requests, but no sibling is named, so differentiation is inferred rather than explicit.

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 explicit when-to-use statement or exclusion; the only routing hint comes from the schema ('from list_signature_requests'). Usage is implied by the singular scope, but the description never says to prefer get_request_progress or get_receipts for adjacent questions.

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