get_app_versions

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

With no annotations provided, the description must fully convey behavior. It states this is a read-only operation ('Get all App Store versions') but omits details on pagination, rate limits, required permissions, or whether the result is sorted. The mention of a 'limit' parameter hints at return size, but behavior is otherwise minimally described.

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, well-structured sentence that front-loads the tool's purpose and includes key details. Every word adds value, with no redundancy or 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?

Given no output schema, the description should clarify the return format. It mentions return fields but not the structure (e.g., array of objects) or pagination behavior. The 'limit' parameter is acknowledged but its relationship to total results is unclear. For a simple retrieval tool, this is adequate but not 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?

Schema description coverage is 100%, so baseline is 3. The description does not add significant meaning beyond the schema; it only loosely ties the return fields to the purpose. For example, it doesn't explain how 'platform' or 'state' filters work beyond what the schema already provides.

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?

Description clearly specifies the action ('get'), the resource ('App Store versions'), and the context ('for a specific app'). It also lists key return fields (version string, platform, release state), distinguishing it from sibling tools like 'get_app' or 'get_build'.

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 implies usage when needing versions for a given app but offers no explicit guidance on when not to use it or alternatives. It does not differentiate from similar list tools such as 'list_builds' or 'list_apps', leaving the agent to infer context.

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