ncloud_create_metrics_group

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

The description only states 'Create' which is consistent with the readOnlyHint false and destructiveHint false, but adds no detail on side effects, prerequisites, or response behavior. The agent cannot infer whether this operation requires specific permissions or has limitations.

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 concise sentence, front-loading the action and resource. However, it could be more efficient by omitting the redundant Korean parenthetical if the English term is sufficient.

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?

Given the tool's moderate complexity (three required parameters, one nested array) and absence of an output schema, the description is too brief. It does not mention return values (e.g., created rule group ID) or confirm success feedback, leaving important gaps for an AI agent.

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?

Schema description coverage is 100% for all three parameters and their nested properties, so the schema already explains them thoroughly. The description adds no extra parameter-level information beyond confirming the action, resulting in the baseline score.

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 'Create' and identifies the resource as 'Cloud Insight rule template' with the Korean phrase for 'metrics group' in parentheses. It distinguishes the action from read tools, but does not differentiate from similar creation tools like ncloud_create_rule_group or ncloud_create_monitor_group among siblings.

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 guidance is provided on when to use this tool versus alternatives such as ncloud_create_rule_group or ncloud_update_metrics_group. The description lacks context for selecting this tool over siblings, leaving the agent without decision support.

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