ncloud_create_nas_snapshot

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

Annotations only provide destructiveHint=false, and the description is consistent with this by indicating a create operation. The description adds the dryRun preview capability, which is useful behavioral context, but it does not disclose details like whether the operation is synchronous, requires specific permissions, or what happens upon success. With limited annotations, the description only partially compensates.

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 that state the core purpose and a key usage tip. There is no wasted wording, and the most important information is front-loaded.

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?

The tool has 4 parameters, no output schema, and minimal annotations. The description covers the basic purpose and the dryRun option but does not mention the return value, prerequisites such as the NAS volume existing, or any side effects. Given the simplicity of the operation, it is adequate but leaves clear gaps for an agent.

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 description coverage is 100%, so all parameters are already documented. The description's mention of dryRun=true is redundant with the schema's description of the dryRun parameter. No additional parameter semantics are provided beyond what the schema already offers, so the baseline score of 3 applies.

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 verb 'Create' and the resource 'snapshot for a NAS volume instance', which is specific and distinguishes this from sibling tools like delete_nas_snapshot, list_nas_snapshots, and restore_nas_volume_with_snapshot. The scope is unambiguous.

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 gives a practical usage tip ('Use dryRun=true to preview') but does not explicitly state when to use this tool versus alternatives or mention any exclusions. The context is implied by the tool's name and description, but there is no comparison with other similar tools.

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