dynadot_set_default_ns

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

With no annotations provided, the description bears the burden of disclosing behavior. It clarifies that the nameservers apply only to new domains and that a maximum of 13 can be set. However, it fails to mention whether this overwrites existing defaults, requires specific permissions, or produces any response.

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 a single, front-loaded sentence that conveys the core action and a key constraint without any extraneous words. Every part serves a purpose.

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?

Given the absence of annotations and output schema, the description is too sparse. It omits crucial details such as the expected nameserver format, success/error responses, and whether the tool can be called multiple times, leaving the agent with significant uncertainty.

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 description adds only the constraint 'up to 13' beyond the schema, which lacks descriptions (0% coverage). It does not explain the format of the array elements (e.g., hostname pattern like 'ns1.example.com'), leaving the agent to guess the expected string format.

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 verb 'Set' and the resource 'default nameservers for new domains,' distinguishing it from siblings like 'dynadot_set_ns' (which likely targets specific domains) and 'dynadot_set_default_dns' (which may set DNS records). The limit '(up to 13)' adds specificity.

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 phrase 'for new domains' provides context that this tool is for setting defaults applicable to future registrations, not for existing domains. However, it does not explicitly state when to use this versus alternatives like 'dynadot_set_ns' or 'dynadot_set_default_dns,' nor does it mention prerequisites or when not to use it.

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