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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing. It does not mention authentication requirements (implied by "mine"), what ratings are returned, whether results are scoped to the caller, or the response shape.

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?

Two words is not conciseness but under-specification; the description lacks the substance an agent needs. It is front-loaded only in the trivial sense that there is nothing else.

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 annotations and no output schema, the description must explain the tool on its own, and it does not. In a large sibling ecosystem containing several rating tools, this is completely inadequate for correct selection or invocation.

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 is only one parameter (region), and the schema documents it fully at 100% coverage including the enum values. The description adds no parameter detail, but per the baseline rule for high schema coverage, a 3 is appropriate.

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?

"My ratings" merely restates the tool name and title with no verb or resource specificity. It hints at the authenticated user's own ratings (as opposed to sibling maps_by_slug_ratings or tanks_by_slug_ratings), but never states what is retrieved or from what domain.

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?

The word "mine" weakly implies this returns the caller's own ratings rather than another entity's, which is a faint usage signal against siblings like tanks_ratings or maps_ratings. However there is no explicit when-to-use, no prerequisites, and no named alternative.

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