ncloud_cdss_get_server_generations

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

The annotation readOnlyHint=true already conveys the safe read-only nature. The description adds only the semantic clarification 'hypervisor types' but does not disclose additional behaviors such as response format or pagination. This does not contradict the annotation, but adds minimal behavioral context.

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 clear sentence of nine words, front-loaded with the action and resource. There is no redundant or filler content.

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 zero-parameter, read-only list tool, the description is adequate. It explains what the tool returns (server generations/hypervisor types) but does not mention the exact return type or any potential edge cases. Given the tool's simplicity, this is a minor gap.

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 tool has zero parameters, so the description carries no burden to explain parameter usage. The parenthetical '(hypervisor types)' adds useful meaning to the term 'generations', which is helpful given no schema provides parameter details.

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 'Get' and the resource 'available server generations (hypervisor types)' with scope 'for CDSS'. This distinguishes it from sibling tools like ncloud_cdss_get_server_spec_list and ncloud_ses_get_server_generations, though it does not explicitly reference alternatives.

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 gives no guidance on when to use this tool versus other similar list tools (e.g., ncloud_cdss_get_server_spec_list, ncloud_cdss_get_node_products). It is a bare statement without any context or alternative references.

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