delete_dns_zone_record

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

Annotations already declare destructiveHint=true, idempotentHint=true, and readOnlyHint=false, so the safety profile is covered structurally. The description adds only the HTTP path and a redundant restatement with a typo ('DNZ Zone'), without disclosing side effects, confirmation behavior, or DNS propagation implications.

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 definition is short and front-loaded, but the second sentence repeats the operation and contains a typo ('DNZ'), reducing precision. It is not verbose, but it also wastes the few words it has.

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 destructive single-record delete, the description gives the endpoint but omits practical context such as whether the deletion is immediate, whether it returns anything, and how it differs from bulk deletion. Annotations and the complete input schema cover much of the safety and parameter burden, making this minimally adequate but not rich.

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 recordId, zoneName, and x-trace-id are already documented in the schema. The description adds no parameter semantics beyond that baseline, which is appropriate given complete schema coverage.

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 names a specific verb and resource ('Delete a DNS zone record') and includes the endpoint path, so the operation is unambiguous. It does not distinguish itself from the sibling bulk_delete_dns_zone_records or delete_dns_zone, which limits differentiation.

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 explicit when-to-use guidance, no mention of alternatives such as bulk_delete_dns_zone_records for multiple records, and no stated prerequisites or exclusions. The operation name implies deletion, but the routing decision is left entirely to inference.

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