set_dns

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

No annotations provided; description discloses key behaviors: it explains the records parameter structure, notes default TTL of 300, and mentions that add_dns_to_current_setting controls overwrite vs append behavior.

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 concise sentences that front-load purpose and provide essential usage details without extraneous information.

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 no annotations and no output schema, the description adequately covers purpose, parameter format, and overwrite behavior. Lacks discussion of return value or error conditions, but remains sufficient for a tool with two parameters.

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 100%, but description adds significant value by detailing the Dynadot API naming convention (main_record_type0..19, subdomain0..9, etc.) and explaining optional fields like ttl and add_dns_to_current_setting, which are not fully covered in schema descriptions.

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?

Clearly states verb 'set' and resource 'DNS records for a domain'. Specifies scope 'main records and up to 10 subdomains', distinguishing from siblings like get_dns, set_nameservers, set_dnssec.

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?

Provides a usage hint on how to pass parameters via 'records', but does not explicitly state when to use this tool over alternatives like set_nameservers or set_dnssec. No 'when not to use' guidance.

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