game_center_challenges_delete_instance

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

No annotations are provided, so the description carries the full burden. The DELETE verb minimally signals a destructive operation, but nothing is said about permanence, whether the deletion cascades to versions/localizations/images, or what permissions are required. For a destructive mutation with zero annotation coverage this is a significant gap.

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 text is short but wastes its only sentence by duplicating the identical endpoint string inside parentheses. No part of it is front-loaded with purpose or behavior, so brevity here reflects under-specification rather than conciseness.

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?

There is no output schema and no annotations, so the description is the only source of context, yet it explains nothing about the effect of the delete or the resource's dependent objects. For a destructive instance-delete tool, this leaves the agent materially under-informed.

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 there is a single required 'id' parameter, so the schema already documents it fully; the description adds nothing beyond echoing {id} as a path segment. Per the high-coverage baseline, 3 is the appropriate floor.

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 a raw endpoint restatement: 'DELETE /v1/gameCenterChallenges/{id}'. The HTTP verb plus resource path do convey that a Game Center challenge is being deleted, but there is no plain-language statement of purpose and no differentiation from siblings beyond the URL fragment, which merely echoes the tool name.

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 or sibling tools such as game_center_challenges_update_instance or game_center_challenges_get_instance. The agent is left to infer everything from the endpoint path.

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