ncloud_set_block_storage_protection

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

Annotations already indicate idempotentHint: true and destructiveHint: false, which cover the safety profile. The description adds no additional behavioral context beyond what annotations provide, such as side effects or return behavior, so it meets the baseline but does not exceed it.

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, short sentence that is front-loaded and to the point. It is efficient but could be slightly more structured, e.g., by explicitly stating the required parameters upfront.

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?

Given the tool's simplicity and absence of output schema, the description is minimally adequate. However, it lacks mention of the response format (e.g., success/failure) or that the operation is idempotent per annotations. It does not fully inform an agent about what to expect after invocation.

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%, with both parameters (blockStorageInstanceNo, isReturnProtection) already well-described in the schema. The description does not add extra meaning or usage details for the parameters, so the baseline 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 verb 'Set' and the resource 'return protection for a block storage instance', making it specific and distinct from sibling tools like ncloud_set_protect_termination (for servers) and ncloud_set_nas_volume_return_protection (for NAS volumes).

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 usage for setting return protection on block storage, but provides no explicit guidance on when to use this tool versus alternatives, nor any prerequisites or exclusions. It relies on the agent to infer context from sibling tool names.

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