ncloud_remove_route_table_subnet

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

Annotations already flag destructiveHint and idempotentHint, so the description's destructive warning initially seems redundant. However, the description adds valuable context by explicitly telling the agent to set confirm=true to execute, which is an essential safety behavior not fully explained in the annotations alone.

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, front-loaded sentence that wastes no words. It packs the operation, the destructive warning, and the execution requirement into a compact, scannable format.

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 removal tool with full schema coverage, no output schema, and safety annotations, the description sufficiently covers the operation, destruction risk, and confirmation requirement. It doesn't elaborate on preconditions or response details, but the tool's simplicity and schema completeness make that acceptable.

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 has 100% description coverage for all parameters, so the baseline is 3. The description adds extra semantic value by highlighting the confirm parameter's gatekeeping role ('Set confirm=true to execute'), which reinforces what the schema states but also frames it as the critical execution guard for a destructive operation.

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 specific verb 'Remove' and resource 'subnet association from a route table', making the tool's purpose immediately apparent. It distinguishes itself from sibling tools like ncloud_remove_route and ncloud_add_route_table_subnet by explicitly naming the association removal 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 clearly conveys the operation and provides a critical usage instruction ('Set confirm=true to execute'). While it doesn't explicitly mention when to choose this over alternatives, the narrowed scope ('subnet association from a route table') makes the usage context clear.

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