ncloud_create_cache_config_group

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

The description adds context about the dryRun behavior, which is useful beyond the annotations' destructiveHint: false. It does not disclose other behavioral traits such as response format or side effects, but given the simple create operation and the annotation covering safety, this is acceptable.

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 two short sentences, front-loaded with the primary purpose, and every word adds value. No fluff or redundant 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?

The tool is simple (4 params, no nested objects), but there is no output schema and the description does not mention what the tool returns or any post-create effects. This leaves a minor gap in completeness, but it is not critical for a basic create operation.

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 100% parameter descriptions, so the description does not need to explain parameters. It mentions dryRun, but the schema already documents that, so no additional semantic value is added.

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 uses a specific verb ('Create') and resource ('Cloud Cache config group'), making it immediately clear what the tool does. It also distinguishes itself from sibling tools like ncloud_cdss_create_config_group and ncloud_delete_cache_config_group by naming the exact resource type.

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 the tool (to create a config group) and provides a useful hint about dryRun for previewing. However, it does not explicitly state when to choose this over alternatives or mention any prerequisites or exclusions, so guidance is only implied.

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