ncloud_create_monitor_group

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

Annotations carry only destructiveHint=false, so the description must supply the behavioral picture, and it supplies almost none. It does not mention that creation is non-idempotent, what temporaryGroup does (create an Event Rule without a monitor group), or that monitorGroupItemList defines the monitored resources. Nothing contradicts the annotations, but the burden is unmet.

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 short sentence, front-loaded with the verb and resource, with the parenthetical bilingual gloss. It is efficient and wastes no words, though it borders on under-specification rather than true conciseness.

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?

With 7 parameters, a nested-monitoring-target array, a type enum, and only a single annotation hint, the description is far too thin. It omits what the tool returns, whether it is idempotent, and how a monitor group relates to the metrics groups and rule groups it will subsequently be used with.

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%, including the type enum, temporaryGroup semantics, and the nested item fields, so the schema does the heavy lifting. The description adds only the Korean gloss '감시 대상 그룹', which does not disambiguate the required prodKey or the relationship between monitorGroupItemList and the group itself. Baseline 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 states a specific verb and resource ('Create a new Cloud Insight monitoring target group'), which separates it from update/delete/list/get monitor group siblings. It also implicitly distinguishes itself from the load-balancer ncloud_create_target_group by qualifying the resource as a Cloud Insight monitoring target group. It does not, however, clarify the relationship to ncloud_create_metrics_group or ncloud_create_rule_group, which are the genuinely confusable siblings in this domain.

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?

There is no when-to-use guidance, no prerequisites (e.g., that prodKey must reference an existing target service), and no mention of alternatives such as ncloud_update_monitor_group or ncloud_create_metrics_group. The agent must infer all routing decisions from the tool name alone.

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