in_app_purchase_versions_create_instance

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: no auth/permission requirements, no note on side effects or what state the new version starts in, no mention of validation rules or error behavior. For a mutating create operation this is a complete gap.

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 first sentence duplicates the identical route string inside parentheses, which is pure waste and does not earn its place. The second sentence is a terse external pointer, so the definition is short but not efficiently 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 create endpoint with a nested JSON:API body, no annotations, and no output schema, the description is far too thin. The pointer to the OpenAPI request schema gives some body-shape access, but nothing explains required relationships, auth, or expected outcome, leaving the agent under-equipped at call time.

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?

Only one parameter exists and schema description coverage is 100%, so the schema already documents 'body' and its components.schemas.InAppPurchaseVersionCreateRequest shape. The description merely repeats the same pointer rather than adding meaning, which lands at the baseline 3 for high schema coverage.

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 route 'POST /v1/inAppPurchaseVersions' does convey a create operation on an in-app-purchase-version resource, so the purpose is inferable. However, it is stated only as a mechanical URL, with no prose explaining what an in-app purchase version is or what creating one does, and nothing distinguishes it from sibling create tools like in_app_purchases_v2_create_instance or in_app_purchase_versions_create_instance's relationship to in_app_purchase_versions_get_instance.

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 alternatives anywhere in the description. An agent cannot tell from this text when creating an in-app purchase version is the right call versus updating or fetching one.

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