list_app_store_version_localizations

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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It only states the action ('List') and content, with no mention of side effects, authentication, pagination, or error behavior. The read-only nature is implied but not explicitly stated.

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, front-loaded sentence that avoids redundancy. Every element ('List', 'localizations', 'app store version', the parenthetical examples) contributes meaning, making it appropriately concise and structured.

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 one-parameter list tool with no output schema, the description adequately conveys the resource and what the response will contain (descriptions, what's new, keywords per locale). It lacks edge-case details but is largely complete given the tool's simplicity.

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%, as the schema already documents 'versionId' as 'The app store version ID'. The description adds extra context about the output content ('per locale') but does not enhance parameter meaning beyond the schema. Baseline 3 applies.

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 states a specific verb ('List') and resource ('localizations for an app store version'), and clarifies the content types with parenthetical examples (descriptions, what's new, keywords per locale). This clearly differentiates it from sibling tools like list_iap_localizations or update_keywords.

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 when to use this tool (for viewing localizations) but does not explicitly mention alternatives or exclusions. It lacks explicit guidance on when not to use it or how it relates to update_* tools or other list_localizations tools.

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