list_app_store_versions

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

No annotations are provided, so the description carries the behavioral burden. It clearly frames the operation as a read-only listing and names the returned attributes, but it does not disclose ordering, pagination, or whether all App Store states are included. There is no contradiction with annotations.

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?

One focused sentence that front-loads the verb and object, with a compact field list after the colon. Every part is useful and there is no filler.

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 single-parameter list tool with an output schema, a minimal description can be sufficient. However, the description omits how to obtain app_id, whether all versions are returned, and how this tool relates to get_app_store_version, making it adequate but not 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 description coverage is 0%, and the description never names app_id. 'for an app' provides only a weak semantic link to the required parameter; no format, source, or meaning beyond the field name is given.

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 a specific verb ('List') and resource ('App Store versions for an app'), and it names the returned fields. It does not explicitly differentiate from the sibling get_app_store_version, so it lacks full sibling distinction.

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?

There is no guidance about when to use this tool versus get_app_store_version or create_app_store_version. The description only states the operation and gives no alternatives, exclusions, or prerequisites beyond the implicit app_id.

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