ncloud_pca_activate_sub_ca

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

With no annotations, the description carries the full burden. It does not disclose side effects, permissions required, whether the operation is idempotent, or what state changes occur beyond activation. This is insufficient for a mutation tool.

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 that is front-loaded and contains no unnecessary words. Every part contributes to the purpose.

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 PKI operations and no output schema, the description is minimal. It does not explain what 'Activate' entails, prerequisites (e.g., the Sub CA must exist, cert must be from the parent CA), or post-activation behavior.

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. The description aligns with param names (certPem, caChainPem) but adds no additional meaning beyond the schema's descriptions. No extra context is provided for caTag.

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 verb 'Activate', the resource 'Sub CA', and the method 'using a signed certificate and CA chain (direct signing method)'. It distinguishes itself from sibling tools like pca_sign_sub_csr, which signs a CSR, by specifying the activation step.

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 mentions 'direct signing method', hinting at an alternative method, but does not explicitly state when to use this tool versus alternatives such as pca_sign_sub_csr or pca_create_ca. No clear exclusions or prerequisites are provided.

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