game_center_matchmaking_queues_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 says nothing about authentication needs, what is created, side effects, or what the response contains. It merely points to an external OpenAPI schema for the request envelope.

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 description is short but wastes its limited space on a verbatim duplicate of the path in parentheses, which carries zero information. It is front-loaded only in the sense that there is almost nothing to load.

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 endpoint with no annotations and no output schema, the description should at minimum explain the effect of the call and any preconditions. Instead it only redirects the agent to an external schema, leaving the behavioral picture incomplete.

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?

Schema description coverage is 100% for the single body parameter, and the schema itself documents the shape reference, so the baseline of 3 applies. The description's pointer to components.schemas.GameCenterMatchmakingQueueCreateRequest adds nothing beyond the schema description already present.

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 is essentially a restatement of the endpoint path and HTTP verb ('POST /v1/gameCenterMatchmakingQueues'), which duplicates the tool name rather than explaining what creating a matchmaking queue accomplishes. It never states the purpose in plain language or distinguishes this create tool from its siblings (update/delete/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 guidance on when to use this tool, when not to, or which sibling to prefer. The agent is left to infer everything from the path alone.

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