ncloud_delete_vpc_peering

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

Annotations already mark destructiveHint=true. The description adds value by including a visual warning emoji and emphasizing 'permanently delete', plus crucially highlights the confirm flag requirement for execution. This is behavioral info beyond annotations. However, it does not address the idempotentHint annotation.

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 with two focused sentences. The first sentence delivers the warning and purpose; the second provides the execution requirement. No unnecessary words, and the critical information is front-loaded.

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 delete operation with no output schema, the description covers the core action and the confirm guard. It could mention idempotency or error cases, but given the annotations and simplicity, it's reasonably complete.

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 input schema already provides descriptions for both parameters with 100% coverage. The description mentions 'set confirm=true to execute', reinforcing the schema's confirm description but adding no new meaning. For vpcPeeringInstanceNo, the schema description is already clear.

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 tool name 'ncloud_delete_vpc_peering' combined with description 'Permanently delete a VPC Peering connection' clearly specifies the verb (delete) and resource (VPC peering). It distinctly identifies the operation among sibling tools like create, accept/reject, and set description.

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 minimal usage guidance: it warns of destructiveness and requires confirm=true to execute. However, it does not explicitly state when to use this tool versus alternatives (e.g., for removing a peering connection). The use case is implied but not articulated.

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