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

There are no annotations, so the description carries the transparency burden. It does disclose that the check involves the AD flag and DNSKEY/DS records, which adds meaningful detail beyond the name. However, it does not clarify whether the operation is read-only, how the query is performed, or what the output contains.

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 one compact sentence with no filler and the core question is front-loaded. It is efficiently written, though the terseness contributes to missing parameter and usage details.

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 one-parameter tool with an output schema, the description captures the essential purpose but leaves q semantics and sibling selection context unaddressed. It is minimally adequate, yet an agent would still need to infer that q represents the zone to check.

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 only parameter, q, has no schema description and schema description coverage is 0%. The description mentions 'zone' but never explicitly connects it to q or explains the expected input format, so an agent must guess that q is a domain/zone name.

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 states a specific check—whether a DNS zone is DNSSEC-signed—and names the technique used (AD flag + DNSKEY/DS), which separates it from generic DNS siblings like dnsquery or dnsverify. It could be stronger by explicitly naming a sibling or using a clearer verb, but the resource and action are identifiable.

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?

No explicit guidance is given for when to use this tool versus alternatives such as dns, dnsquery, dnsverify, or dnsrecon, and no exclusions are mentioned. The specialized DNSSEC wording implies a narrow use case, but selection logic is left largely to inference.

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