ncloud_create_fabric_cluster

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

Annotations already indicate destructiveHint=false. The description adds no additional behavioral traits beyond what the name implies. It does not disclose any side effects, required permissions, or what happens after creation. For a create tool, it would be useful to mention that it is an asynchronous operation or that the new cluster is initially inactive, but no such context is provided.

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 that is front-loaded with the primary action and resource. It avoids redundancy and includes a brief clarifying purpose ('for dedicated physical server grouping'). No fluff or irrelevant details.

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 simple nature of the tool (3 params, no output schema), the description is minimally viable. It could be improved by noting any prerequisites (e.g., a fabric cluster pool must exist) or the outcome beyond just 'create', but it is not severely incomplete. Without an output schema, the description need not explain return values.

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%, so the parameters are already well-documented in the schema. The description does not add any extra meaning about parameters. Baseline of 3 applies because the schema handles the parameter semantics adequately.

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 action ('Create'), the resource ('a new fabric cluster'), and the purpose ('for dedicated physical server grouping'). This distinguishes it from sibling tools like ncloud_list_fabric_clusters, ncloud_get_fabric_cluster_detail, and ncloud_delete_fabric_cluster, which handle other operations on the same resource.

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 usage: use when creating a new fabric cluster. However, it does not explicitly state when not to use it or mention alternatives (e.g., if you need to modify an existing cluster, use change_* tools). No exclusions or prerequisites are given, so it lacks explicit guidance beyond the verb 'create'.

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