list_statistics_resources

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and non-destructive behavior. The description adds no behavioral context beyond what the endpoint path implies, such as the nature of the statistics returned or any operation-specific caveats.

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 extremely short and front-loaded, with no wasted words. The endpoint line is arguably redundant with the name, but it is still a compact, direct statement.

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?

The tool has no parameters, a simple read-only contract, and an output schema that defines return values. Yet the description fails to explain what 'Resource Statistics' means or how this differs from closely named siblings, so an agent may struggle to select it appropriately.

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 input schema has zero parameters, so parameter semantics are trivially complete. With no parameters, the baseline of 4 applies because there is nothing for the description to clarify.

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 'Get Resource Statistics.' clearly identifies the verb and the resource, and the endpoint path confirms the operation. However, it does not distinguish this from siblings like list_resources or list_statistics_bandwidth, and 'Resource Statistics' is not further defined beyond the tool's own name.

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?

No guidance is given about when to use this tool versus any of the many sibling tools. There is no mention of alternatives, exclusions, or context in which this endpoint should be preferred.

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