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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds only an operation ID and a pointer to describe_operation, saying nothing about authentication, pagination, filtering behavior, or what the list returns.

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?

The description is short but wastes space repeating the endpoint twice and including an opaque operation ID. The only useful sentence is the pointer to describe_operation, and it is not front-loaded relative to the repetition.

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 list endpoint with no output schema and two undocumented parameters, the description should convey what is returned, available filtering, and usage context. It instead provides only the URL and a pointer to another tool, leaving the agent under-informed.

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?

There are two parameters with 0% schema description coverage, and the description does not explain query or params semantics. Pointing to describe_operation is better than nothing but does not compensate for the complete lack of parameter meaning in the schema.

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 is essentially the title and endpoint path repeated twice, with no plain-language statement of what insurance policies are or how this list differs from siblings like get_insurance_certificates. It identifies the resource only through the URL, making it a near-tautology.

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 only points to describe_operation as a source of request schemas, which is an operational hint rather than guidance on when to use this tool versus alternatives. There is no when-to-use, when-not-to-use, or sibling differentiation.

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