ncloud_ses_get_cluster_acg

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

The annotations already declare readOnlyHint=true, and the description adds no additional behavioral context such as required permissions, rate limits, or what the response contains. It only restates the tool's purpose without revealing any behavioral traits beyond the 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, concise sentence that conveys the essential information without any redundant or filler words. It is well-structured and immediately front-loads the action and resource.

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 (one required parameter, no output schema, annotations present), the description sufficiently covers the action and resource. While it could mention what the returned rules look like, the low complexity and clarity of 'Get ACG rules' make it adequately 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?

The input schema has 100% coverage with a clear description for the single parameter ('Cluster instance number'). The tool description adds no extra semantic meaning beyond what the schema already provides, 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 uses a specific verb ('Get') and clearly identifies the resource ('ACG rules') and the target domain ('Search Engine Service cluster'). It expands the acronym ACG and distinguishes this tool from general ACG tools like ncloud_get_acg_rules and sibling cluster tools like ncloud_ses_get_cluster_detail.

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 no guidance on when to use this tool versus alternatives. It does not mention when NOT to use it, nor does it reference any sibling tools or alternative approaches (e.g., using ncloud_get_acg_rules for general ACG rules). The usage context is left entirely to the agent's inference.

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