ncloud_ses_get_node_list

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

The readOnlyHint annotation already establishes this as a safe read operation, and the description aligns with that. However, the description adds no further behavioral context such as whether the list includes all node statuses, pagination behavior, or what node attributes are returned.

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 with no filler or redundant information. It clearly states the tool's action and target resource in minimal space.

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 low complexity (one parameter, no output schema) and the read-only annotation covers the safety profile. However, the description does not indicate what the response includes or whether any filtering/pagination exists, which would be helpful for an agent planning to use the result.

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, which is described as 'Cluster instance number.' The description adds no additional parameter semantics beyond what the schema provides, so the baseline 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 resource ('node list for a Search Engine Service cluster'), clearly indicating what the tool returns. It is distinct from sibling tools like get_cluster_detail or get_node_spec_detail, though it doesn't explicitly call out those differences.

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 context implies usage: when you need the node list for a specific SES cluster. However, there is no explicit guidance on when to use this instead of related tools (e.g., get_cluster_detail) or prerequisites like obtaining the serviceGroupInstanceNo.

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