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

With no annotations present, the description does not disclose behavioral traits beyond the operation. It does not mention whether the tool is read-only, if it requires authentication, or any side effects. The description lacks important 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 a single sentence but conveys the core functionality and list of outputs efficiently. It could be improved with structured formatting, but it is not verbose and front-loads purpose.

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 output schema and no annotations, the description provides a reasonable list of returned fields but lacks details on format, pagination, or limitations. It is adequate but not fully complete.

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 coverage is 100% with both parameters described in the schema. The description adds minimal new meaning; it confirms 'search by name or App Store ID' which is already stated. Baseline 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 tool looks up an app on the App Store and lists the data fields (ratings, reviews, version, etc.). It specifies search by name or App Store ID. However, it does not explicitly distinguish itself from sibling tools like app_details, which may overlap in functionality.

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 app_details or list_apps. The description only states what it does without contextual usage advice.

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