ncloud_set_nas_volume_access_control

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

Annotations already indicate idempotent hint and non-destructive nature. The description adds that it sets access control but does not clarify whether it replaces existing rules or merges them. The behavioral context is adequate but not detailed.

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, clear sentence with no unnecessary words. It is concise and front-loaded. However, it is too brief and could include more detail without being verbose.

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 complexity of siblings and lack of output schema, the description is incomplete. It does not clarify the meaning of 'set' versus 'add' or 'remove', nor does it mention return values or the effect on existing access control rules.

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 each parameter described. The description adds minimal value by indicating the two modes (server-based vs custom IP-based) but does not explain how parameters relate or are optional. Baseline score for high coverage.

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 'Set', resource 'NAS volume instance', and scope 'server-based or custom IP-based'. However, it does not distinguish from sibling tools like 'ncloud_add_nas_volume_access_control' which might have a similar purpose.

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 implies usage for setting access control with two modes but does not explicitly state when to use this tool versus the 'add', 'remove', or 'get rules' variants. No guidance on prerequisites or alternatives.

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