dynadot_set_dns

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

With no annotations, the description must disclose behavioral details. It states 'Replace' but does not explain that the default behavior replaces all records unless addToCurrent is true. It omits information about record limits, TTL defaults, or the effect on unspecified records.

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: two sentences with no redundant information. The key action is front-loaded and every sentence adds value.

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 tool modifies DNS records with 5 parameters and no output schema, the description is insufficient. It omits return value, error handling, and parameter interactions (e.g., addToCurrent behavior, TTL default).

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 coverage is high (80%). The description adds minimal value beyond the schema by restating that main and subdomain records can be passed. It does not clarify the missing domainName parameter description.

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 tool replaces DNS records for a domain, with a specific verb ('Replace') and resource ('DNS records'). It distinguishes from sibling tools like dynadot_get_dns, but does not explicitly differentiate from dynadot_set_default_dns.

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 provides no guidance on when to use this tool versus alternatives. It does not mention when not to use it (e.g., for adding records) or compare to similar tools like dynadot_get_dns or dynadot_set_default_dns.

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