Behavior2/5

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

The description adds little beyond the tool name and the destructiveHint annotation. It confirms this is a creation operation, but does not disclose potential implications such as billing, immediate availability, or that the resource persists and must be deleted later. There is no mention of required permissions or region constraints.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence that states the primary purpose without extraneous information. Every word is necessary, and it is immediately clear what the tool does. This is efficient and appropriately structured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite the simple schema and annotations, the description is too minimal for a cloud resource creation tool. It does not mention optional association behavior, lifecycle implications, or the response structure (no output schema exists). An agent would need additional context to understand the full scope of the operation and its consequences.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema fully documents both parameters (serverInstanceNo and publicIpDescription) with clear descriptions, so the description does not need to repeat them. The description adds no additional meaning about parameter usage or relationships, which maintains the baseline score of 3 given 100% schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Create a new public IP instance' clearly identifies the action (create) and the resource (public IP instance). This distinguishes it from sibling tools like ncloud_list_public_ips, ncloud_associate_public_ip, and ncloud_delete_public_ip, which perform different operations on the same resource. The verb and resource are specific and unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It does not mention that this should be used when a new public IP is needed, or that existing IPs should be associated via ncloud_associate_public_ip. No prerequisites or exclusions are stated, leaving the agent without context for selection.

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