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

With no annotations, the description carries the full behavioral burden. It discloses deprecation status and points at the request schema, but says nothing about permissions, whether the release takes effect immediately, reversibility, or rate limits for what is clearly a mutating create operation.

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?

Front-loading [DEPRECATED] is good structure, but the parenthetical duplicates the exact same POST path verbatim, which is pure waste. Three fragments where one clear sentence would suffice.

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 mutating create tool with no annotations, no output schema, and a nested JSON:API envelope required in the body, the description leaves too much unsaid — no replacement guidance for the deprecation and no behavioral detail beyond a schema pointer.

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% and there is a single body parameter already documented as 'JSON body. Shape: components.schemas.GameCenterLeaderboardReleaseCreateRequest.' The description repeats that same pointer rather than adding any field-level meaning, 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 names the resource and the HTTP verb (POST /v1/gameCenterLeaderboardReleases), so an agent can tell it creates a leaderboard release. However, it is largely a restatement of the tool name mapped onto a REST path rather than a semantic explanation of what a 'leaderboard release' is in Game Center terms, and it does not differentiate itself from the many neighbouring release/create siblings.

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] tag is a useful usage signal, but the description never says what to use instead (e.g. a v2 or leaderboard-set release equivalent) nor under what conditions this call is still acceptable. No when-to-use or when-not-to-use guidance beyond the deprecation flag.

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