ncloud_delete_nas_snapshot

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

Annotations already provide destructiveHint and idempotentHint. The description adds the confirmation requirement ('Set confirm=true to execute') and the permanence of deletion, which are valuable behavioral details beyond the annotation flags. No contradiction detected.

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 sentence with a warning emoji, front-loading the destructive nature. Every word is purposeful and there is no redundancy.

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 two-parameter delete tool with annotations, the description covers the action, permanence, and confirm requirement. It could mention retry safety or error behavior, but given the low complexity and annotation coverage, it is sufficiently complete.

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?

Input schema covers both parameters with full descriptions (100% coverage), so the description adds little beyond reinforcing the confirm parameter's necessity. The schema already states 'Must be true to actually execute the destructive operation'.

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 'Permanently delete a NAS volume snapshot', specifying the verb and resource. The 'NAS volume snapshot' qualifier distinguishes it from generic snapshot deletion tools like ncloud_delete_snapshots.

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?

Usage is implied by the action 'delete' and the resource name, but there is no explicit when-to-use guidance or comparison with alternatives such as ncloud_restore_nas_volume_with_snapshot or ncloud_change_nas_snapshot_config. The confirm=true instruction is more about parameter usage than tool selection.

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