app_store_versions_create_instance

Creates a new App Store version in App Store Connect by submitting an AppStoreVersionCreateRequest payload, enabling release setup and version management.

Instructions

POST /v1/appStoreVersions (POST /v1/appStoreVersions) Body shape: see OpenAPI components.schemas.AppStoreVersionCreateRequest for the full JSON:API envelope.

C2/5.0
Behavior2/5

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, yet it says nothing about permissions, side effects, required auth, or what state changes result. The only signal is the implicit 'POST = create' mutation, which is minimal.

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 is short but not efficient: it repeats 'POST /v1/appStoreVersions' twice in immediate succession and provides no actual content. Redundancy rather than conciseness.

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?

For a create operation taking a nested JSON:API envelope body, with no annotations and no output schema, this is inadequate. It doesn't describe required body fields, the JSON:API structure, or success behavior, leaving the agent dependent on an external, unresolvable schema reference.

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?

With one parameter and 100% schema description coverage, the schema already documents the body, so the baseline is 3. The description merely points to the same OpenAPI schema reference the schema field already cites, adding no syntax or field-level meaning.

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 for what the tool name already conveys, and it repeats the path verbatim in parentheses. It never explains what an App Store version is or what creating one accomplishes in the domain, and with hundreds of sibling create tools it offers no differentiation.

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 versus alternatives, nor any prerequisites (e.g., an existing app, build, or platform). The agent gets no routing information at all.

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