get_dns_quota

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

The readOnlyHint annotation already signals a safe read operation, and the description is consistent with that. It adds context that the tool returns usage and limit values, but provides no further behavioral detail such as auth requirements, rate limits, or whether the quota applies to the whole account only.

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 with no filler, front-loads the action verb, and conveys the full purpose efficiently. Every word contributes meaning.

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 no-input, read-only quota tool, the description is nearly complete: it identifies the exact resource, scope, and general return content ('usage and limits'). It would benefit from naming the actual quota fields or return structure since there is no output schema, but the tool is simple enough that an agent can correctly select and invoke it.

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?

With zero parameters, the empty input schema is sufficient and the baseline is 4. The description does not need to explain parameter meaning, and it adds no unnecessary parameter confusion.

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 uses a specific verb ('Get'), names the resource ('DNS quota usage and limits'), and scopes it to the IONOS CLOUD account. This clearly distinguishes it from DNS zone/resource/list siblings like get_dns_zone or list_dns_zones, even without reading their schemas.

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 implies usage for checking account-wide DNS quota/limits, and the zero-parameter schema makes invocation straightforward. However, there is no explicit guidance about when to prefer this tool over alternative account or DNS tools, nor any exclusions when it should not be used.

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