ncloud_delete_nas_snapshot

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

Annotations already provide destructiveHint: true and idempotentHint: true. The description adds the confirmation step and the 'permanently delete' phrasing, reinforcing the safety warning. However, it does not disclose behavior beyond the annotations, such as error handling or prerequisite conditions.

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: a single line with a warning emoji and two short sentences. It is front-loaded with the destructive warning, and every word is relevant. No unnecessary content.

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 2-parameter deletion tool with no output schema and good annotations, the description covers the essential: the destructive nature and the confirm requirement. It could mention the irreversibility or the need for the snapshot to exist, but overall it is sufficiently complete given the structured data.

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 coverage is 100% with both parameters documented. The description only mentions the 'confirm' parameter, repeating what the schema states. It does not add new meaning or clarify usage beyond the schema descriptions. 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 clearly states the action ('delete') and the resource ('NAS volume snapshot'), with a warning indicator. The verb 'delete' is specific and non-ambiguous. Among sibling tools like 'ncloud_create_nas_snapshot' and 'ncloud_list_nas_snapshots', this tool's purpose is well-distinguished.

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 provides instructions on how to execute ('confirm=true') but gives no guidance on when to use this tool as opposed to alternatives such as 'ncloud_list_nas_snapshots' for viewing or 'ncloud_restore_nas_volume_with_snapshot' for restoration. No explicit when/when-not advice is present.

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