ncloud_pca_create_ca

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

Annotations are minimal (only destructiveHint: false). The description does not disclose behavioral traits such as whether creating a CA requires specific permissions, what happens if the alias already exists, or any irreversible actions. It only states the creation action without side effects.

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 very short (one sentence). While concise, it omits important details and the mention of 'x509Parameters' is imprecise. It could be restructured to clearly list required parameters and explain the two CA types.

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 complexity of creating a CA with 14 parameters and no output schema, the description is insufficient. It does not explain what the tool returns (e.g., CA identifier, status), nor does it clarify the relationship between the numerous X.509-related parameters. The agent lacks necessary context for successful invocation.

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%, so baseline is 3. However, the description mentions 'x509Parameters' which is not an actual parameter in the schema, causing confusion. It does not add useful meaning beyond what the schema already provides; actually it misleads. Therefore score is reduced to 2.

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 clearly states the tool creates a new Private CA (Root or Sub) and lists required parameters. It differentiates from sibling tools like ncloud_pca_list_cas or ncloud_pca_get_ca which are for reading. However, it references 'x509Parameters' which is not a parameter in the schema; the actual X.509 fields are individual parameters. This slight mismatch reduces clarity.

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 (e.g., when to create Root vs Sub CA, or when to use other PCA tools). No exclusions or context about prerequisites are given.

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