ncloud_detach_policy_from_group

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

The description adds the confirm requirement beyond the annotations which already indicate destructive hint. It does not contradict annotations (idempotent hint is not contradicted).

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—one sentence—and front-loaded with a warning emoji. Every word is necessary and earns its place.

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 tool with low complexity and no output schema, the description covers the core action and the key confirm behavior. It is mostly complete, though could mention return values or prerequisites.

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 coverage, the baseline is 3. The description adds value by explaining the confirm parameter's purpose beyond the schema description, though groupId and policyId are not elaborated.

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 a specific verb ('Remove') and resource ('IAM policy from a group'), clearly distinguishing it from sibling tools like attach or detach from sub-account.

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?

It explicitly states the requirement to set confirm=true to execute, providing a clear usage guideline. However, it does not mention when to use this tool versus alternatives like detach from sub-account.

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