end_app_availability_pre_orders_create_instance

Create an end pre-order request to stop app availability pre-orders on App Store Connect.

Instructions

Behavior1/5

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

No annotations are provided, so the description carries the full burden. It discloses nothing about mutation side effects, required auth/scopes, idempotency, or what the operation returns — only that it is a POST. For a create/mutation endpoint this is a severe gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description wastes space by repeating the identical 'POST /v1/endAppAvailabilityPreOrders' twice in parentheses, and the useful content (deferral to the OpenAPI component schema) is a single clause. Short, but redundantly under-specified rather than tightly written.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The body is a nested JSON:API envelope with no output schema and no annotations, yet the description outsources all substance to an external OpenAPI document that may not be available to the agent. For a mutation endpoint with a complex nested payload, this is inadequate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and there is a single required 'body' parameter, so the schema does the heavy lifting; baseline 3 applies. The description adds no syntax, field, or format detail beyond naming the request schema, so it neither helps nor compensates.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose2/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description only restates the HTTP method and path (POST /v1/endAppAvailabilityPreOrders), which is a tautology of the tool name rather than a statement of what the tool does. It never explains what an 'end app availability pre-order' is or what creating one accomplishes, so an agent cannot distinguish its purpose from the many sibling *_create_instance tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool, no prerequisites, and no mention of alternatives among the hundreds of sibling create/list tools. The only conditional hint is an implicit pointer to an external OpenAPI schema.

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