ncloud_pca_list_end_certs

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

The readOnlyHint annotation already covers the safety profile, and the description adds that it 'Returns serial numbers', which is useful. However, it does not disclose whether the list includes revoked/expired certificates, pagination behavior, or ordering. This is acceptable but not rich enough for a 4.

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?

Two short sentences that are front-loaded with the primary action ('List all end-entity certificates') and conclude with the return value. No wasted words, highly scannable.

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 tool with one parameter and no output schema, the description provides the essential information: what it lists, the scope (specific CA), and the key return value (serial numbers). It lacks details on pagination or status filtering, but these are not critical for basic 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?

The schema covers the only parameter (caTag) with a description ('CA tag value'), so the baseline is 3. The tool description does not add further semantic detail about the parameter beyond restating that it specifies 'a specific CA', which does not materially improve understanding.

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 uses a specific verb ('List') and identifies the exact resource ('all end-entity certificates issued by a specific CA'). It distinguishes this from sibling tools like ncloud_pca_list_cas (lists CAs) and ncloud_pca_get_end_cert (gets a single certificate), making the purpose clear.

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 the tool is used to enumerate end-entity certificates for a CA, but it does not explicitly state when to choose this over alternatives such as ncloud_pca_get_end_cert or ncloud_pca_revoke_end_cert. No exclusionary or alternative guidance is provided, so usage context is only implicit.

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