game_center_achievements_releases_get_to_many_relationship

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

With no annotations, the description carries the full behavioral burden, and it only discloses deprecation status. It says nothing about pagination (despite the limit parameter), authentication requirements, or what the relationship response contains, so an agent lacks the context needed to call it correctly.

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 description is short but wastes its entire length duplicating the endpoint path twice. The useful '[DEPRECATED]' marker is front-loaded, but the redundant parenthetical is pure noise rather than earning 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, read-only relationship fetch with full schema coverage and no output schema, the definition is minimally adequate: the deprecation warning is the key context and it is present. It omits any return-shape or relationship-vs-related clarification, but the tool itself is simple enough that these are minor gaps.

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% for both parameters (id, limit), so the schema already documents them adequately. The description adds nothing about parameter meaning, which is acceptable at the baseline but does not compensate further.

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 essentially the HTTP path 'GET /v1/gameCenterAchievements/{id}/relationships/releases' repeated verbatim in parentheses, which restates what the tool name already encodes. It does convey that this reads the releases relationship of a gameCenterAchievement, so the resource and verb are inferable, but the redundant duplication adds no clarifying value over the 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?

The only usage signal is the '[DEPRECATED]' tag, which usefully tells the agent to avoid this tool. However, no alternative is named and there is no explanation of the relationship-vs-related distinction against the sibling game_center_achievements_releases_get_to_many_related, leaving the agent to guess which to call.

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