game_center_activity_localizations_delete_instance

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

No annotations are provided, so the description must carry the entire behavioral burden, and it discloses nothing: no mention of permanence/irreversibility, required permissions, or cascading effects on related resources. The parenthetical repetition of the same path adds no information.

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?

Very short, but the same endpoint string is duplicated in parentheses, which is pure redundancy rather than concision. It is under-specified rather than efficiently trimmed, with no front-loaded statement of purpose.

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 single-resource deletion with no annotations and no output schema, the description should at minimum state that the operation is irreversible and what it removes. None of that is present, leaving the definition inadequate for safe invocation.

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 the single 'id' parameter, which the schema already documents as 'the id of the requested resource'. The description adds no syntax, format, or sourcing guidance, so the baseline of 3 applies since the schema does 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 text restates the tool name as an HTTP path ('DELETE /v1/gameCenterActivityLocalizations/{id}') with no additional explanation of what a game center activity localization is or what deleting one accomplishes. It is essentially a tautology of the name, though the verb+resource pairing is at least identifiable.

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, when not to, or which sibling (e.g. game_center_activity_localizations_update_instance) is the alternative. The DELETE verb is the only implicit signal, and no prerequisites or preconditions are stated.

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