game_center_app_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, yet it discloses nothing: not what fields are required, whether the operation is reversible, what prerequisites (e.g., an app store version) must exist, or what happens on success. It only points at an external OpenAPI schema.

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 '(POST /v1/gameCenterAppVersions)' duplicates the path stated immediately before it, and the remaining sentence only redirects to another document. Almost none of the text earns its place.

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 mutation tool with no annotations, no output schema, and an opaque freeform body, the description is drastically incomplete. An agent cannot determine required fields, side effects, or dependencies from it.

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?

The single 'body' parameter is nominally 100% covered, but both the schema and the description only forward to 'components.schemas.GameCenterAppVersionCreateRequest' with an empty additionalProperties object, so no real field-level semantics are provided. The description merely duplicates the schema's pointer verbatim, adding zero meaning.

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 endpoint ('POST /v1/gameCenterAppVersions') without explaining what a Game Center app version is or what creating one accomplishes. It is essentially a tautological restatement of the tool name 'game_center_app_versions_create_instance' rather than a semantic purpose statement.

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 among the many sibling create/update tools. The agent gets only the HTTP route and nothing about when this operation is appropriate.

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