ncloud_kms_delete_acl_rule

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

Annotations already declare destructiveHint=true, and the description reinforces this with a prominent ⚠️ Destructive warning. It adds the critical behavioral requirement that confirm=true must be set to execute, which is beyond what annotations alone provide; no contradiction is present.

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 includes a warning symbol and a direct execution instruction. Every element earns its place with no filler or redundancy.

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 destructive delete tool, the annotations and schema cover safety and parameters, while the description covers the operation and confirmation requirement. It does not explain how to obtain ruleId or post-deletion behavior, but these are not essential given the rich schema and sibling tool context.

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 provides 100% parameter coverage with descriptions for keyTag, ruleId, and confirm, so the description need not repeat those details. It adds only the confirm=true execution hint, which is already stated in the schema, yielding no extra semantic value.

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 tool removes an IP address from the ACL rules for a KMS key, with a specific verb and resource. It implies the delete operation in contrast to sibling add/get ACL tools, though it does not explicitly mention alternatives.

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 implies when to use the tool (to remove an IP from a KMS key's ACL) and provides the key instruction to set confirm=true to execute. However, it does not mention alternatives like ncloud_kms_add_acl_rule or list-first prerequisites, so usage guidance is implicit rather than explicit.

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