app_store_version_localizations__create

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

Annotations are neutral (not read-only, not idempotent, not destructive). The description adds no behavioral context beyond 'Create'. It does not disclose side effects, required permissions, or error conditions.

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 plus endpoint, making it concise. It could be slightly more structured by front-loading key details, but it is not verbose.

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 creation tool with no output schema, the description is incomplete. It does not explain what the response contains, that a relationship to appStoreVersion is required, or any validation rules. This leaves the agent guessing.

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%, so the description does not need to repeat parameters. However, it adds no additional meaning beyond the schema structure, such as explaining the purpose of each field or constraints.

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 action ('Create') and resource ('App Store version localization'), distinguishing it from sibling tools like get, update, delete. The endpoint reinforces the create operation.

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 on when to use this tool versus alternatives. It does not mention prerequisites, such as requiring an existing appStoreVersion, or when to choose create over update.

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