Создать DNS-запись

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only restates the action and gives the API endpoint; it does not mention side effects, idempotency, required permissions, error cases, or response format. This is minimal and does not meaningfully disclose behavior beyond what the name implies.

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 concise, consisting of two short fragments: the action and the API path. It is front-loaded and contains no filler, with every word contributing to understanding the tool's purpose.

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 6 parameters (3 required) and no output schema. The schema fully documents parameters, but the description omits behavioral context such as expected response or prerequisites (e.g., domain must exist). It is minimally viable but not rich enough for a mutation tool without annotations.

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 provides 100% coverage with descriptions for all six parameters, so the baseline is 3. The tool description itself adds no additional parameter semantics, but the schema already handles this dimension adequately.

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 'Добавить' (Add) with the resource 'DNS-запись' and includes the HTTP POST endpoint, making the tool's function unambiguous. It clearly distinguishes this as the create operation compared to sibling tools like update_dns_record and delete_dns_record.

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?

There is no guidance on when to use this tool versus alternatives such as update_dns_record or delete_dns_record. The description does not state conditions, prerequisites, or scenarios where this tool should be preferred, leaving the agent without explicit direction.

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