ncloud_detach_policy_from_sub_account

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

Annotations already provide destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description adds useful context by stating that policy IDs go in the request body and that confirm=true is required, but it does not disclose permissions, reversibility, or failure behavior.

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?

Two short sentences front-load the destructive warning and action, then immediately give the two operational details an agent needs: body placement and confirm=true. There is no filler or redundant explanation.

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 destructive mutation with full parameter schemas and safety annotations, the description is largely complete: it states the action, target, required confirmation, and a non-obvious API transport detail. It lacks only explicit sibling-selection guidance, which is already penalized under usage guidelines, and there is no output schema to describe.

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%, so the schema fully documents each parameter. The description reinforces that policy IDs travel in policyIdList and that confirm must be true, but these details largely duplicate 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 clearly identifies the action ('Remove one or more IAM policies') and the target resource ('from a sub account'). This distinguishes it from nearby siblings like detach_policy_from_group and delete_policy, and the 'one or more' phrasing signals batch support.

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 gives no explicit guidance about when to use this tool versus attach_policy_to_sub_account or detach_policy_from_group. It explains mechanics (body parameter, confirm flag) but not the decision context that would route an agent to the correct sibling.

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