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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It says nothing about pagination, filtering semantics, authentication requirements, or the shape of the result, leaving all behavioral traits undocumented.

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?

It is short, but the two parenthetical halves are identical, so the text wastes its single sentence duplicating itself rather than front-loading any useful purpose or scope information.

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 7-parameter collection endpoint with no output schema and no annotations, the description should at minimum describe what is returned and how filtering works. It provides none of that, leaving the definition materially incomplete.

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% with 7 well-described parameters (limit, include, filters, fields), so the schema does the heavy lifting. The description adds no parameter meaning of its own, which is the baseline-3 case when coverage is high.

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 just the HTTP endpoint path repeated twice, which restates the tool name rather than explaining what the tool does. An agent can only infer 'list leaderboard set member localizations' from the name itself, not from the description text.

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 mention of prerequisites, and no differentiation from the many sibling collection tools. Nothing tells an agent why it would call this instead of a related localization endpoint.

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