app_store_version_localizations__update

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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds the HTTP method PATCH, which hints at partial update semantics, but does not elaborate on side effects or any remaining behavior beyond what annotations offer.

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, information-dense sentence that lists the key updatable fields and includes the endpoint path. Every word adds value, with no fluff or unnecessary repetition of the schema.

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 it is an update operation with two parameters and no output schema, the description adequately covers purpose and fields. It omits an explicit note that unspecified fields remain unchanged (a typical PATCH semantic), but the PATCH notation in the description partially hints at that. Overall, it is sufficiently complete for an update tool with detailed annotations and schema descriptions.

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 descriptions for both 'id' and 'body'. The description adds context by listing the editable fields (description, keywords, what's new, promotional text, support/marketing URLs), which semantically groups them as 'store listing text' and clarifies what the body payload should contain.

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 action ('Update') with a clear resource ('store listing text for one language of a version') and enumerates the exact fields involved. This clearly distinguishes it from sibling create/delete/get operations on the same resource.

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 verb 'Update' and the phrase 'for one language of a version' provide clear context that this tool is for modifying an existing localization. However, it does not explicitly state alternatives such as 'use create for new localizations' or 'use delete for removing', so it lacks explicit when-not guidance.

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