ncloud_cdss_get_os_monitoring

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

Annotations already declare readOnlyHint=true, so the description does not need to restate it. The description adds the specific metric categories (CPU, memory, disk), but does not disclose any other behavioral aspects like pagination, rate limits, or data freshness. It is adequate but minimal given the annotation coverage.

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?

Single sentence conveying core purpose with no extraneous words. Well-structured and immediately understandable.

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 description lists metric types but does not describe output structure, which is missing an output schema. For a read-only monitoring tool, it would benefit from stating what the response contains (e.g., time series, values, units). Considering the complexity of monitoring data, it is somewhat incomplete.

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% description coverage, so the schema already documents the parameters. The description mentions the metrics but does not provide additional meaning or relationship to the parameters (e.g., that startTime/endTime define the time range for these metrics). No added value beyond the schema.

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?

Description clearly states it gets OS-level monitoring metrics for CDSS cluster nodes, specifying CPU, memory, and disk. However, it does not differentiate from sibling tools like ncloud_cdss_get_monitoring, which may have overlapping scope.

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 explicit guidance on when to use this tool versus alternatives. For example, ncloud_cdss_get_monitoring or ncloud_ses_get_os_monitoring are not mentioned. The description implies it is for OS metrics, but lacks exclusions or context.

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