create_dns_record_tool

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

With no annotations provided, the description carries the full burden of explaining behavioral traits. It only repeats the tool's name without disclosing any side effects, idempotency, permission requirements, or rate limits. For a mutating operation, this is a significant gap.

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 sentence, front-loaded and without any filler. It is appropriately concise for a straightforward create operation, and the schema handles detailed parameter documentation.

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 and an output schema, the description is minimal. It does not explain the operation's context, such as the need for a valid zone_id or how it relates to sibling tools. The output schema exists, so return values are handled, but the description still lacks important contextual guidance for correct usage.

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 schema description coverage is 100%, so all parameters are already described in the schema. The description adds no additional meaning beyond what the schema provides, which meets the baseline of 3. It does not explain parameter relationships or default behaviors beyond schema notes.

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 action: 'Create a new DNS record.' It specifies the verb and resource, and there is no ambiguous terminology. However, it does not explicitly distinguish from sibling tools like update_dns_record or list_dns_records, though the name itself does.

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 prerequisites, common use cases, or scenarios where other tools (e.g., update or list) would be more appropriate. For a create operation, it could at least imply that it's for new records, but it offers no context.

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