ncloud_ses_get_server_generations

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

The description is consistent with the readOnlyHint annotation (a 'Get' operation), so no contradiction. However, it adds no behavioral insight beyond the annotation—no mention of response format, pagination, or limitations. With annotations covering the read-only aspect, the description is minimally adequate but not enriched.

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?

A single, concise sentence that is front-loaded with the action ('Get') and resource ('available node server generations'). Every word earns its place; no unnecessary elaboration.

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 parameterless lookup, and the description names the exact data returned. However, it does not specify the output structure or when to use it relative to other SES lookup tools. Given the absence of an output schema, more detail on the return value could be expected, but the tool's simplicity mitigates this 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 input schema has zero parameters, so parameter semantics are trivially covered. The description correctly omits parameter details since none exist, and the baseline for zero parameters is 4. No additional parameter explanation is needed.

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 retrieves 'available node server generations' for 'Search Engine Service', using a specific verb and resource. It is distinguishable from siblings like ncloud_ses_get_server_specs and ncloud_cdss_get_server_generations by the resource term and service scope, though it does not explicitly name 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?

No information is given about when to use this tool versus alternatives like ncloud_ses_get_server_specs or ncloud_ses_get_node_products. There are no exclusions, preconditions, or contextual guidance provided.

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