ncloud_delete_nas_volumes

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

Given annotations already declare destructiveHint=true, the description adds value by stating 'Permanently' and the requirement for a confirmation flag, explaining a behavioral safeguard. It also clarifies the plural nature, but does not discuss return values or side effects beyond deletion, which is acceptable for a destructive operation with annotations covering safety.

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 extremely concise—two short sentences. It front-loads the critical warning with 'Destructive:' and then specifies the action and the confirmation requirement. Every word adds value, with no redundancy or filler.

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 with two parameters and provided annotations, the description conveys the essential information: the action, the target resource, and the confirm guard. Without an output schema, it does not describe return data, but that is not critical for a destructive call. It lacks explicit guidance on prerequisites (e.g., existing volumes) but remains sufficiently complete for an agent to use correctly.

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 input schema already provides full descriptions for both parameters (100% coverage). The description repeats the confirm=true requirement, which adds marginal emphasis but no new parameter details. It does not elaborate on the format or structure of nasVolumeInstanceNoList beyond what the schema states, so a baseline score of 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 clearly states the action ('Permanently delete'), the resource ('NAS volume instances'), and supports plural usage ('one or more'). It distinctly identifies this as a deletion tool for NAS volumes, differentiating it from sibling tools like delete_nas_snapshot or other delete operations.

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 includes an explicit prerequisite ('Set confirm=true to execute') which is useful guidance. However, it does not mention alternatives (e.g., listing volumes first with ncloud_list_nas_volumes) or when not to use this tool, leaving the context partially implied rather than explicit.

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