game_center_challenge_version_releases_delete_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 for a destructive operation. It does disclose the useful fact that the endpoint is deprecated, but says nothing about whether deletion is permanent/irreversible, what related data is removed, required scopes, or whether the release must be in a particular state.

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 and front-loads the [DEPRECATED] warning, which is good. However, the endpoint string is duplicated in parentheses with no added value, so one of the two segments is pure redundancy.

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 destructive, unannotated delete with no output schema, the description is inadequate: it neither explains the deprecation (replacement path, sunset timing) nor the consequences of deletion. The deprecation tag is the only piece of agent-relevant context present.

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?

Only one parameter exists and schema description coverage is 100% ('the id of the requested resource'), so the schema already fully documents the input. The description adds no format, source, or sourcing guidance for the id, so the baseline of 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 DELETE verb against the gameCenterChallengeVersionReleases resource via the REST path, so the action and target are identifiable and distinguishable from the sibling _create_instance and _get_instance tools. However, it never states the purpose in plain language — it is essentially the raw endpoint string restated, which leaves the agent to infer what a 'version release' actually is.

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 when-to-use guidance, no prerequisites, and no indication of when this delete is appropriate versus the sibling create/get tools. The only contextual signal is the [DEPRECATED] tag, which discourages use but does not explain what to use instead.

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