ncloud_dns_create_records

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

The description adds no behavioral context beyond the verb 'Create'. Annotations only include destructiveHint=false, which indicates non-destructive but does not clarify batch behavior, idempotency, validation, or whether existing records are affected. The description carries a low disclosure burden but fails to add any meaningful behavioral traits.

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, front-loaded sentence with no wasted words. It immediately states the action and target resource, making it highly concise and well-structured.

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?

The tool is a simple create operation with a rich schema that documents all parameters. However, the description lacks context about multiple record creation (array input), how to obtain domainId, or any caveats about record types. It is minimally complete but leaves gaps for an agent to infer behavior.

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 parameters are well-documented in the schema. The description itself does not add additional parameter semantics, making the baseline 3 appropriate. No parameter meanings are explained beyond the 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's function: 'Create DNS records for a specific Global DNS domain'. The verb 'Create' and resource 'DNS records' are specific, and 'for a specific Global DNS domain' adds scope. This distinguishes it from sibling tools like ncloud_dns_update_records and ncloud_dns_delete_records.

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 explicit guidance is provided about when to use this tool versus alternatives. The verb 'Create' implies usage when creating DNS records, but there is no mention of prerequisites (e.g., domain must exist), exclusions, or comparison with update/delete tools. This is essentially no guidance beyond the tool's name.

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