ncloud_delete_bucket

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

Annotations already indicate the tool is destructive and idempotent. The description adds value by specifying that deletion is permanent, the bucket must be empty, and requires a confirmation flag. This goes beyond the annotations without contradicting them.

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?

A single sentence with a warning emoji that is immediately informative. It is highly concise, front-loads the destructive nature, and every part of the description earns its place. No unnecessary words.

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 absence of an output schema, the description covers the essential aspects: what the tool does, the prerequisite, and the execution requirement. It could mention the result of a successful deletion (e.g., bucket removed), but the current information is sufficient for an agent to use the tool correctly.

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 coverage is 100%, so the baseline is 3. The description adds meaningful guidance for the 'confirm' parameter by stating 'Set confirm=true to execute', which reinforces the schema's description and clarifies the required interaction between parameters. No additional value for bucketName, but overall a net positive.

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 permanently deletes an Object Storage bucket. It includes a warning emoji and specifies the prerequisite (bucket must be empty) and the confirmation mechanism. This distinguishes it from sibling tools like create or list buckets.

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 provides explicit conditions for use: bucket must be empty and confirm must be true to execute. This gives clear when-to-use guidance. However, it does not mention alternative tools or explicitly state when not to use this tool, which would strengthen the score further.

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