game_center_challenge_version_releases_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 behavioral burden, and it discloses almost nothing beyond the implied read-only nature of GET. The '[DEPRECATED]' tag is genuine behavioral context (the endpoint may be removed or unsupported), which earns some credit, but there is no information about authentication, error behavior, or the returned representation.

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 single sentence wastes half its length by repeating the same URL path twice in parentheses, adding zero information. It is short but not efficient, and the deprecation marker is the only content that earns 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?

With no annotations and no output schema, an agent would need to know whether this returns a full resource, what relationships the include/fields parameters affect (the schema hints at this but the description does not), and what deprecation implies for reliability. The description supplies none of that, so it is incomplete for the agent's decision.

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%: id, include, and the two fields_* sparse-fieldset parameters are all documented in the schema. The description adds nothing beyond the path template, so the baseline of 3 applies when the schema does all the work.

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 verb plus the URL path, duplicated in parentheses: "[DEPRECATED] GET /v1/gameCenterChallengeVersionReleases/{id} (GET /v1/gameCenterChallengeVersionReleases/{id})". It conveys that it reads a single game center challenge version release by id, but it never explains what a 'challenge version release' is or how it differs from siblings like game_center_challenge_version_releases_create_instance or game_center_challenge_versions_get_instance. This is closer to restating the name than to stating a purpose.

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 alternatives, no prerequisites, and no mention of what the deprecation means operationally. The only signal is the word DEPRECATED, which tells an agent to be cautious but not what to do instead.

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