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

With no annotations, the description must fully convey behavioral traits. It only states 'get detailed information', omitting critical details like read-only nature, pagination, authentication requirements, or return format. The output schema exists but is not referenced. This under-disclosure forces the agent to guess 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?

The description is short (one sentence), but it lacks necessary detail. It is under-specified rather than concise. Every word should earn its place, but here the brevity comes at the cost of clarity and completeness.

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?

The tool has 3 required parameters and an output schema, yet the description fails to explain the output or how to effectively use the parameters. Given the complexity and the presence of sibling tools, the description is incomplete, offering only a minimal characterization.

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%, meaning no parameter descriptions exist in the schema. The tool description adds no information about what app_id, country, or language mean or how to format them (e.g., IS codes). The agent must rely solely on parameter names, which is insufficient.

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 uses the verb 'get' and resource 'detailed information about a specific app', which indicates the tool's purpose. However, it does not specify what kind of detailed information, making it somewhat vague compared to siblings like google-play-search which search for apps. It is clear but not specific.

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?

No guidance is provided on when to use this tool versus alternatives such as google-play-search or google-play-list. The description does not mention prerequisites or typical use cases, leaving the agent to infer usage without support.

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