ncloud_associate_public_ip

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

Annotations already declare idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds no behavioral details beyond the action itself, but it does not contradict the annotations. No extra context like side effects or preconditions is provided.

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?

A single, direct 9-word sentence that starts with the action verb and states the object. No wasted words, perfectly concise.

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 two-parameter action with full schema coverage and helpful annotations, the description is mostly adequate. It lacks usage guidance and behavioral context, but the tool's complexity is low, so the overall information is sufficient 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?

Schema description coverage is 100%; both 'publicIpInstanceNo' and 'serverInstanceNo' have clear descriptions in the schema. The tool description adds no additional parameter semantics beyond what the schema already states.

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 uses the specific verb 'Associate' with clear resources: 'a public IP with a server instance.' It unambiguously distinguishes this tool from siblings like 'ncloud_disassociate_public_ip', 'ncloud_create_public_ip', and 'ncloud_delete_public_ip'.

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?

No guidance is provided about when to use this tool versus alternatives. It does not mention prerequisites, such as requiring an unassociated public IP or the server being in a valid state, nor does it suggest when to prefer the disassociate or create operations.

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