ncloud_nks_get_versions

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

The readOnlyHint annotation already indicates this is a safe read operation. The description adds the specific context that it targets cluster creation versions, which is helpful, but it does not disclose any additional behavioral traits such as return format, pagination, or defaults. With the annotation present, the description provides minimal extra value beyond the structured data.

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 that directly states the tool's purpose. Every word earns its place, and there is no redundant or tangential 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?

For a simple list tool with optional parameters and read-only annotations, the description is adequate and complete. It clearly identifies the tool's role in the NKS workflow, and the schema handles parameter details. However, it does not describe the shape of the response, which could be useful but is not critical for a list endpoint.

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 input schema fully describes both parameters (hypervisorCode and isRegionalSupport) with clear descriptions, so the schema coverage is 100%. The description adds no additional parameter-level meaning beyond what the schema already provides, so a baseline score of 3 is appropriate.

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 verb 'List' and specific resource 'available Kubernetes versions for NKS cluster creation'. It is unambiguous and distinguishes this tool from similar listing tools like ncloud_ses_get_versions or ncloud_cdss_get_kafka_versions by explicitly mentioning NKS.

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 phrase 'for NKS cluster creation' implies when to use this tool, but there is no explicit guidance on when not to use it or which alternatives exist. Sibling tools like ncloud_nks_upgrade_cluster are not mentioned, leaving usage context somewhat implicit rather than clearly delineated.

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