ncloud_register_external_certificate

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

Annotations include destructiveHint=false, indicating a non-destructive operation. The description adds little beyond that; it does not disclose side effects, permissions, validation behaviors, or idempotency. It is not contradictory, but the added behavioral context is minimal.

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, focused sentence that immediately conveys the tool's purpose with relevant examples. There is no redundant 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 straightforward nature of registering a certificate, the description combined with the fully documented schema is largely complete for an agent to select and invoke the tool. It lacks explicit return-value or alternative-tool guidance, but those are not critical here.

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 description coverage is 100%, with all four parameters (privateKey, certificateName, certificateChain, publicKeyCertificate) clearly described. The tool description itself adds no parameter-level information beyond what the schema already provides, so it meets the baseline.

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 ('Register') and resource ('external SSL certificate issued by a third-party CA'), with concrete examples (Let's Encrypt, ZeroSSL, DigiCert). It distinguishes itself from sibling tools like ncloud_issue_private_certificate by specifying the certificate source.

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 clear context for when to use the tool: when registering an external certificate from a third-party CA. However, it does not explicitly mention alternatives or state when not to use it, though the scope is implicitly defined by the 'external' and 'third-party CA' wording.

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