game_center_activities_delete_instance

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

With no annotations, the description carries the full behavioral burden, yet it says nothing about irreversibility, cascading deletions (localizations, images, releases, achievement/leaderboard associations), required permissions, or any error/confirmation behavior. A bare method+path line leaves the agent blind to the consequences of a destructive operation.

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 repeats the identical method+path string, adding zero information and failing the 'every sentence earns its place' test.

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 destructive DELETE with no annotations and no output schema, the definition omits what is deleted, what else is affected, and how failures surface. Nothing an agent needs to invoke it safely or correctly is present.

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?

There is only one parameter (id) and schema description coverage is 100%, so the schema already documents it as 'the id of the requested resource'. The description adds nothing beyond the path template, but per the high-coverage baseline a 3 is appropriate.

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 tool name as an HTTP method and path ('DELETE /v1/gameCenterActivities/{id}'), duplicated verbatim in parentheses. It conveys that a Game Center activity is deleted, but adds no scoping, differentiation, or clarifying detail beyond what the tool name already tells the agent.

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 versus siblings like game_center_activities_update_instance or game_center_activity_version_releases_delete_instance. No prerequisites, no exclusions, no alternative routing are provided.

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