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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description adds the meaningful extra fact that creator or admin access is required, which the annotations do not convey; it stops short of describing pagination or empty-result 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?

It is short and front-loaded with the action, so it is easy to scan. But the text is verbatim identical to the title, so the opening sentence adds no information beyond the structured title field.

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 simple read-only list with no output schema, the essentials (what it lists, access requirement) are present. Given 0% schema coverage on two parameters and no explanation of what a 'signed file' record contains, it is only minimally complete.

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%, so the description carries the full burden, yet it explains neither parameter. offer_id is inferable from the name, but the optional request_id is undocumented anywhere, and no format or idempotency semantics for it are given.

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?

Tautological: description restates name/title.

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?

It states the access prerequisite (creator or admin), which is useful context for whether the agent can call it at all. However, it gives no guidance on when to choose this over yardstick_offers_signed_files_download or yardstick_offers_documents_list, so the selection logic is left implicit.

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