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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds real behavioral value beyond that: results are ordered newest first, delivered one page at a time, and the reply carries 'page, pages and total', plus each item's kind and added date.

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 dense sentence that front-loads the scope ('Every file on the person's PolicyVera profile') before ordering, paging and item shape. Every clause carries information; the parenthetical is compact but slightly crowded.

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, annotation-backed read tool with no output schema, the description covers scope, ordering, pagination mechanism and item fields well enough to call correctly. Only the missing page upper bound and the absence of explicit sibling routing keep it from being 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 coverage is 0% and the single 'page' parameter has no schema description, so the description must carry the load — and it does, explaining that pagination is page-based and that the reply reports page, pages and total. It omits the schema's 1–50 bound on page, a modest remaining gap.

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 resource (every file on the person's PolicyVera profile) and enumerates its contents — policies, ID cards, binders, certificates, other documents — so an agent knows this is the full-listing tool rather than a single-document fetch like get_my_document. It stops short of explicitly naming that sibling as the alternative, which keeps it out of the top band.

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?

Usage is implied rather than stated: 'every file' plus paging suggests browsing a complete document list, contrasting with the singular get_my_document. There is no explicit when-to-use, when-not-to-use, or named alternative, so the agent must infer the routing.

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