in_app_purchase_localizations_v2_get_instance

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

No annotations are provided, so the description carries the full disclosure burden, yet it states nothing about authentication, pagination, cache behavior, or what the resource looks like. It merely echoes the endpoint path.

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 text is short but wastes its only content: the path is duplicated verbatim in parentheses, adding zero information. Brevity here stems from omission rather than disciplined concision.

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?

With no annotations, no output schema, and four parameters, the description should explain the single-resource semantics and sparse-fieldset options. Instead it provides only the raw endpoint, leaving an agent without enough context to invoke confidently.

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%, with all four parameters (id, include, fields_inAppPurchaseVersions, fields_inAppPurchaseLocalizations) documented in the schema itself. The description contributes nothing to parameter meaning, so the baseline 3 for high coverage 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 is a restatement of the tool name/URL path ('GET /v2/inAppPurchaseLocalizations/{id}'), which implicitly conveys a single-resource fetch but adds no verb/resource framing beyond what the name already encodes. It does not distinguish itself from siblings like in_app_purchase_localizations_get_instance or the create/update/delete variants. This is tantamount to a tautology.

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 when-to-use guidance, no prerequisites, and no mention of alternative tools. An agent gets nothing about when this single-instance GET is preferable to the collection or relationship endpoints.

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