ncloud_create_nas_snapshot

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

The annotation destructiveHint=false is consistent with snapshot creation (non-destructive). The description adds value by mentioning the dryRun preview mode, which is beyond the annotation. However, it omits other behavioral traits like API limits or permission requirements.

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?

Two sentences: first states purpose, second adds a key usage note. No redundant information. Efficient and 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?

Given the tool's simplicity and 100% schema coverage, the description is complete enough. It covers the core action and a safe preview option. However, it does not mention prerequisites (e.g., NAS volume existence) or provide guidance among sibling snapshot tools.

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%, so parameters are already explained. The description adds context for dryRun (preview), but this is already in the schema description. It does not add substantial meaning beyond what the schema provides.

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 ('Create a snapshot') and the resource ('NAS volume instance'). It differentiates from sibling tools like delete, list, and restore snapshots, and adds the dryRun option for safe preview.

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 a usage hint ('Use dryRun=true to preview') but does not explicitly state when not to use this tool or compare it to alternatives like restore. The context is clear but lacks exclusion criteria.

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