getUsageQuota

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

With no annotations provided, the description carries the full burden and does well: it discloses that the operation is read-only, specifies the HTTP method, and surfaces the rate-limit constraint. It does not describe the response shape, but for a simple no-argument GET this is a minor gap.

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 compact sentence that front-loads the core action, then adds the essential rate-limit and read-only context. Every word earns its place.

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 zero-parameter, read-only quota lookup, the description provides the endpoint, method, and rate limit—enough for an agent to select and invoke the tool correctly. It does not explain the return payload, but the tool is simple enough that this does not block correct use.

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 tool has zero parameters and the schema is empty, so the description has no parameter semantics to add. The baseline of 4 applies because no parameter guidance is needed for correct invocation.

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?

States a specific verb ('Get') and resource ('usage quota'), and reinforces it with the exact endpoint. This is clearly distinct from the sibling tools, which target other resources like analytics, customers, or subscriptions.

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 clear context by identifying this as a quota/rate-limit check and explicitly noting the 100-requests-per-minute limit. It does not name alternatives, but the resource is unambiguous among the siblings.

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