Create Dns Record

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

With no annotations, the description carries the full burden of behavioral disclosure, but it only says 'Create a new DNS record.' It does not mention side effects like DNS propagation or duplicate conflicts, permission requirements, or the consequences of creation. This is a significant gap for a mutation operation.

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 single sentence is concise and free of filler, but it is under-specified; it does not front-load any caveats or context. It is appropriately sized for a trivial tool, yet it borders on under-specification rather than effective conciseness.

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?

Despite having 8 parameters with nuances such as TTL auto only when proxied, priority required for MX, and proxied only for certain record types, and no annotations, the description omits all operational context. An agent has to infer usage from the schema and sibling names, leaving the description incomplete for correct invocation.

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 each of the 8 parameters already has a descriptive explanation. The description adds no parameter-level information, but the schema fully compensates, earning the baseline 3.

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 'Create a new DNS record.' restates the tool name and title almost verbatim, adding no additional scope or qualifiers. It states the operation but provides no differentiation from sibling tools beyond the verb 'create', which is already inherent in the name.

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?

No guidance on when to use this tool over update_dns_record or delete_dns_record, nor any prerequisites such as the need for an existing zone. The description relies entirely on the tool name to convey usage context.

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