ncloud_kms_get_key_version_list

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

The readOnlyHint annotation already indicates a safe read operation, but the description adds no additional behavioral context such as pagination, version states, or response format. It doesn't go beyond what the annotation already provides.

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, clear sentence with no redundant words. It is appropriately sized for a simple list operation and front-loaded with the action.

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 list operation with one well-documented parameter and a readOnlyHint annotation, the description adequately covers the essential purpose. No output schema or complex behavior exists to require additional explanation.

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 schema fully documents keyTag with 'Key tag - unique identifier derived from key name' (100% coverage). The description does not add any parameter semantics beyond what the schema already provides, so the baseline of 3 is appropriate.

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 and resource: 'Get list of all versions for a specific KMS key.' It clearly differentiates from sibling tools like ncloud_kms_get_key_list (which lists keys) and ncloud_kms_get_key_info (which gets key info).

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 (listing versions of a key) but provides no explicit guidance on when to use this tool versus alternatives, nor any exclusions. The context is clear, but no sibling differentiation or when-not-to-use guidance is given.

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