get_usage

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

Annotations already indicate readOnlyHint=true and openWorldHint=true, covering safety and dynamic behavior. The description adds that the tool provides traffic/request usage statistics, which is a slight semantic clarification, but it does not disclose any additional behaviors such as pagination, date filtering, or required permissions beyond what annotations imply.

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, short sentence that is front-loaded with the main action and object. It contains no filler or redundant information, making it highly efficient.

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?

Given the tool's simplicity (one required parameter, read-only, output schema present), the description is mostly complete. It lacks explicit usage guidance and parameter details, but the core purpose is clear. The absence of deeper context is acceptable for this low-complexity tool.

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 has one parameter, 'provider', with 0% description coverage. The description mentions 'for a provider' but does not clarify valid values (e.g., provider ID, name, or format). Since the description does not compensate for the lack of schema descriptions, the semantics remain largely inferred from the parameter name.

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 clearly states the verb 'Get' and the specific resource 'traffic / request usage statistics for a provider', which distinguishes it from sibling tools like get_provider_info (provider details) and check_balance (financial balance). It is unambiguous and easily understood.

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 provides no explicit guidance on when to use this tool versus alternatives. It does not mention any prerequisites, exclusions, or mention of sibling tools. Usage context is only implied by the tool name and generic resource description, so an agent receives limited direction.

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