Удалить DNS-запись

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

With no annotations provided, the description carries the full behavioral burden. It does disclose that confirm=true is required and the HTTP method is DELETE, which signals destructiveness. However, it does not state that deletion is permanent or irreversible, nor does it mention any prerequisites like domain ownership or potential side effects.

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, comprising two short sentences. It front-loads the action and includes the essential API path. Every word contributes to understanding, with no redundancy or filler.

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?

This is a simple delete operation with three parameters, all covered by the schema. The description adds the critical confirm requirement and the exact endpoint. It could optionally mention irreversibility, but overall it provides enough context for an agent to correctly invoke the tool in most scenarios.

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 description coverage is 100%, so all parameters are already documented in the schema. The description mentions confirm:true, which is already present in the schema, adding no extra semantic value. This aligns with a baseline score of 3 when the schema handles parameter details.

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 action ('Удалить DNS-запись' – delete DNS record) and specifies the exact resource via the HTTP endpoint. This distinguishes it from sibling tools like create_dns_record or update_dns_record by its unambiguous DELETE verb and target path.

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 a clear usage context: to delete a DNS record, you must set confirm to true. It doesn't explicitly list alternatives or when not to use the tool, but the operation is inherently distinct from the other DNS-record tools, and the endpoint makes the purpose obvious.

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