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

No annotations are provided, so the description must disclose behavioral traits such as read-only nature, rate limits, or data source specifics. It only lists operations and required params, with no mention of return formats, pagination, or side effects, leaving the agent with minimal 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 organized as a summary line followed by a bulleted list of operations with required params, which is scannable and front-loaded. It could be slightly more concise by not repeating the operation name in the trailing label (e.g., 'Search'), but overall it earns its length.

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?

Given the multi-operation nature of this tool and no output schema, the description is complete enough to list all available operations and their required inputs, but it lacks information about return values, optional parameters, and any constraints. This is a minimum viable description for invocation, though not fully comprehensive.

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 only defines operation and a generic 'args' object, while the description maps each operation to its required parameter (e.g., q for search, app_id for reviews). This adds essential semantic information beyond the schema, though it omits descriptions of what those parameters mean and any optional parameters.

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 opens with 'Google Play Store data' and enumerates ten specific operations (search, app_reviews, app_details, categories, top charts). This clearly states the tool's resource and scope, distinguishing it from the many sibling tools that focus on other domains.

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 operation-by-operation required parameters, which tells the agent how to invoke each endpoint. However, it does not explicitly state when to choose this tool over alternatives or when not to use it, leaving usage context only implied by the 'Play Store' domain.

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