Set domain nameservers

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

Beyond the destructive/open-world annotations, it discloses asynchronous queueing, replacement of prior delegation, DNSSEC transition handling, refusal conditions that must not be bypassed, and API-key permission requirements. This adds substantial behavioral context for a mutation tool.

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 front-loaded with the core action and remains dense but purposeful. Each sentence adds operational context without 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?

For a destructive asynchronous registrar operation with a fully described input schema and no output schema, the description covers the important mechanics: delegation replacement, exclusions, permissions, and DNSSEC follow-up. An agent has enough context to call and handle it correctly.

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 the schema already documents domain_id, nameservers, and idempotencyKey thoroughly. The description reinforces the hostname-not-IP constraint but does not add much beyond the schema, which is the expected baseline for high 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 states a precise verb and resource: queue an asynchronous registrar nameserver change for an owned domain. It also clarifies the parent-zone delegation effect, which clearly separates it from DNS-record or PTR tools.

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?

It explains when the change applies, requires hostnames rather than IPs, notes that same-domain nameserver IP records are managed separately, and explicitly excludes DNS records and PTR. The permission requirement and DNSSEC transition guidance make the usage conditions unusually complete.

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