ncloud_delete_nas_volumes

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

The description discloses that the operation is destructive and permanent, aligning with annotations (destructiveHint: true). It adds context beyond annotations by specifying the confirm parameter requirement. However, it does not discuss idempotency (annotated as idempotentHint: true) or potential outcomes for already deleted volumes, but this is minor.

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 with a prominent warning emoji and a clear instruction. Every word is meaningful, and it is front-loaded with the key message ('Destructive'). No unnecessary 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?

For a simple delete operation, the description covers the essential aspects: what it does, its destructive nature, and the requirement to confirm. No output schema is present, so return values are not needed. It could mention prerequisites (e.g., volume existence) but is adequate for safe usage.

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 description adds value for the confirm parameter by explaining its role in executing the destructive action. For nasVolumeInstanceNoList, the schema already provides a clear description. With 100% schema coverage, the baseline is 3, and the additional context for confirm justifies a 4.

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: permanently delete one or more NAS volume instances. It uses a specific verb (delete) and resource (NAS volume instances), and the warning emoji distinguishes it from other NAS management tools like ncloud_get_nas_volume_detail or ncloud_change_nas_volume_size.

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 explicitly instructs to set confirm=true to execute the operation, which is critical for preventing accidental deletion. It also includes a 'Destructive' warning, signaling caution. However, it does not elaborate on when to use this tool versus alternatives (e.g., for detaching volumes), but the purpose is clear enough.

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