Delete DNS Record

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

Annotations already indicate destructive and idempotent nature (readOnlyHint=false, destructiveHint=true, idempotentHint=true). The description adds a concrete behavioral detail: 'Removes the record immediately', which is not obvious from annotations alone and clarifies the timing.

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: a single sentence with an emoji prefix. Every word serves a purpose, and the structure is front-loaded with the action type. There is no redundancy or fluff.

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 simple delete operation with two parameters, the description covers the essential behavior (delete by ID, immediate effect). It references the source of record IDs (dns_list) in the schema. It does not discuss error handling or reversibility, but given the output schema existence and straightforward purpose, it is mostly complete.

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?

Two required parameters are fully described in the input schema (zone_id and record_id). The description adds no additional semantic value beyond what the schema provides, so it scores at baseline.

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 the specific verb 'Delete' and clearly targets a 'DNS record from a Cloudflare zone by record ID'. This makes the action unambiguous and distinguishes it from sibling tools like dns_create and dns_list.

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 implicitly guides by specifying the required parameters (record ID from dns_list results) and the immediate effect. However, it lacks explicit guidance on when to use this over alternatives (e.g., dns_create) or prerequisites like zone ownership.

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