game_center_matchmaking_queues_update_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 mention of required permissions, whether the update is partial or full replacement, reversibility, or side effects on a live matchmaking queue.

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 but not concise in the useful sense: the path is repeated twice and the only substantive content is a pointer to an external OpenAPI component rather than a self-contained explanation. This is under-specification, not efficiency.

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 a nested request body, no annotations, and no output schema, the description should explain the update semantics and payload envelope. Instead it defers entirely to an external spec an agent may not be able to read.

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% and the schema already states the body shape as components.schemas.GameCenterMatchmakingQueueUpdateRequest, which the description merely repeats. Per the high-coverage baseline this is a 3, though the description contributes no added 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 only restates the HTTP method and path ('PATCH /v1/gameCenterMatchmakingQueues/{id}'), duplicated verbatim in parentheses. It adds nothing beyond what the tool name already conveys, so it is effectively a tautology rather than a statement of what the tool does.

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 prerequisite, and no mention of the sibling update/create/delete tools for matchmaking queues. An agent gets zero routing help.

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