ncloud_remove_route_table_subnet

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

Annotations already provide destructiveHint and idempotentHint. The description adds the safety mechanism of the confirm parameter, which is valuable. However, it does not disclose other behaviors like idempotency (already annotated) or failure conditions (e.g., if subnet is not associated or route table doesn't exist).

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, using a single sentence plus emoji to convey the destructive nature and the need for confirmation. No wasted words, and the most 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?

Despite low complexity, the description is too minimal. It does not mention success/error behavior, prerequisites (route table existence, active association), or return values. An agent may not have enough context to use the tool correctly without additional inference.

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?

With 100% schema description coverage, the input schema already explains each parameter adequately. The description does not add further semantic meaning beyond repeating the confirm flag requirement, so a 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 ('Remove') and the resource ('subnet association from a route table'). The destructive warning provides context, but it does not explicitly differentiate from sibling tools like ncloud_add_route_table_subnet, which is the inverse operation.

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 lacks guidance on when to use this tool versus alternatives such as ncloud_add_route_table_subnet or ncloud_delete_route_table. It only mentions setting confirm=true, but does not explain prerequisites or scenarios where removal is appropriate.

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