ncloud_get_nas_volume_access_control_rules

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

The annotation readOnlyHint=true already indicates a safe read operation, and the description's 'Get' is consistent. The description adds that it returns a 'list' of rules, but it does not disclose details such as possible empty results, ordering, or response structure. This is acceptable for a simple getter with read-only annotation.

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 that immediately states the action and resource, with no unnecessary words or repetition of the tool name.

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 read-only tool with one well-documented parameter and no output schema, the description adequately conveys the purpose and expected return ('list of access control rules'). It is sufficiently complete for the agent to select and invoke the tool correctly, though a mention of the rule structure could enhance completeness.

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% for the single parameter nasVolumeInstanceNo, with a clear description ('NAS volume instance number') provided in the schema. The description adds no additional parameter semantics, which is fine given the schema already fully covers it.

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 uses the specific verb 'Get' and identifies the resource as 'access control rules configured for a NAS volume.' This clearly distinguishes the tool from sibling mutation tools like ncloud_add_nas_volume_access_control, ncloud_set_nas_volume_access_control, and ncloud_remove_nas_volume_access_control.

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?

No guidance is provided on when to use this tool versus alternatives such as the set/add/remove access control operations. The description simply states what it does without offering context, exclusions, or prerequisites.

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