hl_user_rate_limit

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

No annotations are provided, so the description carries full responsibility. It only says 'info', implying a read operation, but discloses no details about authentication, rate limits, return behavior, or side effects. This is minimal behavioral disclosure.

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 a single sentence, making it concise in length, but it is under-specified and lacks substantive content. It is not a waste of words, but it does not fully earn its place given how little it conveys.

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 minimal description, the tool is incompletely specified. It does not explain what 'userRateLimit' refers to, how the user parameter is used, or how this tool fits among the many sibling tools. The presence of an output schema slightly reduces the need for return details, but the description is still too thin.

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?

The schema has one parameter 'user' with 0% description coverage. The description does not explain the parameter's format, meaning, or relationship to the 'userRateLimit' mention. It adds no explicit value beyond what the parameter name suggests.

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 'User API rate limit info (userRateLimit)' provides the resource but lacks an explicit verb like 'get' or 'return'. It is close to a tautology of the tool name, though it adds 'API' and 'info'. It does not distinguish from sibling tools, so it is somewhat vague.

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 description gives no guidance on when to use this tool versus alternatives. With many sibling user-related tools, there is no mention of context, exclusions, or preferred scenarios, leaving the agent without any decision support.

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