game_center_achievements_localizations_get_to_many_relationship

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

No annotations are provided, so the description carries the full burden. It discloses only the deprecation and the HTTP verb; nothing about read-only safety, pagination behavior, or what happens when the id is invalid. A GET path is not sufficient behavioral disclosure.

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 flag, but it wastes space by printing the same endpoint twice, once inside parentheses, so it is not maximally economical.

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 two-parameter relationship GET with no annotations and no output schema, the description leaves the agent without any migration path or behavioral context. It is minimally adequate structurally but tells the caller almost nothing they cannot infer from the name.

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% (both 'id' and 'limit' are documented in the schema), so the schema already does the heavy lifting. The description adds no syntax or semantic detail beyond that, which is the baseline-3 case.

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 endpoint ('GET /v1/gameCenterAchievements/{id}/relationships/localizations'), which is a tautology of the name rather than an explanation of what the tool returns in agent-usable terms. It offers no differentiation from the many sibling '*_localizations_get_to_many_relationship' tools.

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?

The '[DEPRECATED]' prefix is genuinely useful guidance to avoid the tool, but no replacement or alternative is named, and there is no statement of when this relationship traversal is appropriate versus e.g. game_center_achievements_localizations_get_to_many_related.

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