ncloud_ses_get_os_monitoring

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

The readOnlyHint annotation already signals this is a safe read operation. The description adds context by specifying the OS-level and node scope, but it does not disclose other behavioral aspects such as required permissions, pagination, rate limits, or the exact structure of the returned monitoring data.

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 is front-loaded with the action and resource. Every word contributes to understanding the tool's purpose with no redundancy or irrelevant details.

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 monitoring data retrieval with a read-only annotation and fully described parameters, the description is mostly complete. It could optionally mention that monitoring data is returned for a time range or that the required IDs come from cluster/node lists, but the schema already covers start and end time parameters.

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 description coverage is 100%, so all four parameters are already documented with descriptions. The tool description does not add meaning beyond the schema, but it does align the term 'node' with the computeInstanceNo parameter implicitly.

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') with a clear resource ('OS-level monitoring data for a Search Engine Service node'). It distinguishes itself from siblings like ncloud_ses_get_monitoring by specifying the OS-level scope and node target.

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 context (OS-level monitoring for a specific SES node) but does not explicitly state when to use this tool versus alternatives such as ncloud_ses_get_monitoring or ncloud_ses_get_dashboard. There are no exclusions or alternative recommendations.

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