game_center_leaderboard_set_images_v2_get_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 only behavioral signal is the implicit read-only nature of 'GET' in the path. It says nothing about authentication, permissions, whether the resource must exist, error behavior, or what the response contains for an image resource with upload state fields.

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 the entire content is a verbatim duplicate of the same path in parentheses — pure waste with zero front-loaded value. 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?

For a single-resource GET with no output schema and no annotations, the description should at least identify the resource and what the caller receives. Instead it provides only the route, leaving the agent to infer everything about the returned image resource and its relationships from the tool name alone.

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%, so all four parameters (id, include, fields_gameCenterLeaderboardSetImages, fields_gameCenterLeaderboardSetLocalizations) are documented in the schema with descriptions and enums. The description adds no parameter meaning beyond the schema, which is the baseline 3 case when the schema does the heavy lifting.

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 bare restatement of the endpoint path 'GET /v2/gameCenterLeaderboardSetImages/{id}', duplicated in parentheses. It does not name the resource in human terms (a Game Center leaderboard set image) or state what retrieving it accomplishes, so it functions as a tautology of the tool name rather than a 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?

No guidance whatsoever about when to use this tool versus siblings such as game_center_leaderboard_set_images_get_instance (the non-v2 variant), game_center_leaderboard_set_images_v2_create_instance, or the update/delete siblings. Nothing indicates prerequisites, ID provenance, or when to prefer v2 over v1.

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