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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds the REST endpoint but no additional behavioral traits such as authentication requirements, rate limits, or side effects. The description is consistent with the annotations and does not contradict them, but it provides minimal extra behavioral context.

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 one concise sentence followed by the endpoint. It is front-loaded with the action and resource, contains no redundant information, and every element earns its place. No filler or unnecessary detail.

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 tool with one parameter, the description is adequately complete. It states the purpose and provides the endpoint, while the schema covers the parameter. There is no output schema, so the description could optionally mention the return format, but 'Read the age rating declaration' strongly implies the response is that declaration. This is sufficient for the tool's complexity.

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?

The input schema fully describes the only parameter 'id' as 'ID from the matching list call,' so schema coverage is 100%. The description does not add any parameter details beyond the schema. With full schema coverage, the baseline of 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?

The description clearly states the action: 'Read the age rating declaration for an app info.' It uses a specific verb ('Read') and a specific resource ('age rating declaration'), distinguishing it from sibling tools like the update variant and other app_info sub-resources. The REST endpoint further clarifies the exact scope.

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 description provides clear context: use this tool when you need to read the age rating declaration for an app info. It doesn't explicitly name alternatives or exclusions, but the read-only purpose is obvious and the endpoint clarifies the operation. No conflicting usage instructions are present.

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