dynadot_set_default_dns

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

With no annotations, the description carries full burden but does not disclose behavioral traits such as whether existing defaults are overwritten, if changes are reversible, or any side effects. The tool is a mutation but no safety or effect details are provided.

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?

Two sentences with clear front-loading: first sentence states purpose, second explains parameters. No wasted words. Appropriate length for the tool's complexity.

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 3 parameters, no output schema, and no annotations, the description is incomplete. It lacks details on DNS record types, allowed values, TTL behavior, and what the tool returns. Users need more context to use 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 0%, so description must add meaning. It explains mainRecords are for root domain and subRecords for subdomains, but does not define fields like type, value, valueX, or ttl. Minimal value beyond schema.

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 sets default DNS records for new domains, mentioning main and subdomain records. It differentiates from siblings like dynadot_set_dns (for existing domains) and dynadot_set_folder_dns (folder-level) by specifying 'for new domains'.

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 gives basic usage instruction ('Pass main records and/or subdomain records') but lacks explicit guidance on when to use this tool versus alternatives like dynadot_set_dns or dynadot_set_folder_dns. No when-not-to-use or prerequisite information.

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