ncloud_pca_get_ca_crl

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds the output format (PEM), which is helpful but does not disclose potential behavioral traits like empty CRL handling, error conditions, or performance characteristics.

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 extremely concise (15 words) and front-loads the core purpose. Every word adds value; there is no redundancy or extraneous information.

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 tool's simplicity (one parameter, read-only, no output schema), the description covers the essential information: what it does and the output format. It is sufficient for an AI agent to select and invoke the tool correctly, though it could mention that the CRL is an X.509 CRL or that the CA must be active.

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%, and the schema already defines caTag as 'CA tag value'. The description does not add further parameter semantics beyond the tool name and schema, so the baseline score 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 clearly states the action ('Get'), the resource ('CRL of a Private CA'), and the output format ('PEM format'). It distinguishes itself from sibling PCA tools like ncloud_pca_get_ca (get CA details), ncloud_pca_get_ca_chain (get chain), and ncloud_pca_list_cas (list CAs).

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 explicit guidance on when to use this tool versus alternatives, or any prerequisites (e.g., CA must exist). For a simple get operation, usage is implied, but the absence of any contextual direction limits the score.

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