game_center_leaderboard_set_images_get_instance

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

With no annotations, the description carries the full burden. It does disclose two useful behavioral facts: the operation is a read ('GET') and the tool is '[DEPRECATED]'. It says nothing about auth requirements, error behavior, or what the response contains, leaving gaps for a getter with no output schema.

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-loads the deprecation warning, which is good. But the trailing '(GET /v1/... (GET /v1/...))' repeats the path twice, a redundant clause that does not earn its place.

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 deprecated single-resource getter with full schema coverage and no output schema, the definition is minimally adequate. It omits the two things that would matter most here: a plain-language purpose and a pointer to the replacement tool.

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 the four parameters (id, include, fields_*) are already documented in the schema. The description adds no additional meaning about how include or fields should be used, so the baseline 3 applies.

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 conveys a GET (read) operation on the gameCenterLeaderboardSetImages resource by id, which is more specific than the bare name. However, it is expressed purely as a REST path with a redundant parenthetical duplicate and gives no plain-language statement of purpose or differentiation from the sibling v2 getter.

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?

It offers no when-to-use guidance and does not name the likely replacement (game_center_leaderboard_set_images_v2_get_instance). The '[DEPRECATED]' marker implies an agent should avoid it, but the description never says so explicitly or points to an alternative.

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