in_app_purchase_images_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 authentication requirements, no statement that this mutates state by creating a resource, no rate limits, and no note that the JSON:API envelope must be wrapped correctly or the call fails.

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?

It is short and front-loaded, but the parenthetical repetition of the same method and path adds no information, and the single actionable sentence is delegated to an external OpenAPI document the agent may not have in context.

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 tool with no annotations, no output schema, and an opaque body schema that only points at an external component definition, the description should at minimum explain what is being created and what the request must contain. It supplies none of that, leaving the agent unable to construct a valid call.

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?

There is one parameter (body) with 100% schema description coverage, so the baseline is 3. The description's pointer to components.schemas.InAppPurchaseImageCreateRequest is an exact duplicate of what the schema already states, adding no new semantic detail about required fields or envelope structure.

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 restates the HTTP method and path ("POST /v1/inAppPurchaseImages"), which is a near-tautological echo of the tool name rather than a plain-language statement of what it does (create an in-app purchase image resource). It gives no differentiation from close siblings like in_app_purchase_images_v2_create_instance or subscription_images_create_instance, so an agent cannot tell which create tool applies from the text alone.

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 indication of when to use this tool versus the v2 variant or the other image-creation siblings, and no prerequisites or context are stated. The description is purely a mechanical endpoint restatement.

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