ncloud_dns_apply_domain

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

Annotations already provide idempotentHint=true and destructiveHint=false. The description adds that the tool applies 'pending changes', which implies prior record modifications, but does not elaborate on effects like DNS propagation or potential service disruption. Acceptable given annotation coverage.

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?

Single sentence with clear action and context. No wasted words, front-loaded with verb and resource.

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?

For a simple tool with one parameter and good annotations, the description is sufficient. It explains the purpose and pending-change context. Lacks mention of return value or side effects, but output schema is absent, so completeness is reasonable.

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?

Only one parameter (domainId) with schema description 'Domain ID to apply' (100% coverage). The tool description does not add further meaning beyond the schema, which is adequate. Baseline 3 applies.

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?

Description clearly states the action ('Apply') and resource ('Global DNS domain'), and the parenthetical clarifies that applying means publishing DNS records. It distinguishes from sibling tools like ncloud_dns_create_records (which creates but doesn't publish) and ncloud_dns_rollback_domain.

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 implies when to use (to publish pending changes) but does not explicitly state prerequisites, alternatives, or when not to use. No contrast with siblings like ncloud_dns_rollback_domain or ncloud_dns_create_records.

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