ncloud_create_bucket

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

The description adds the dryRun preview behavior, which is beyond the annotations that only declare destructiveHint=false. However, it doesn't disclose other behavioral details such as idempotency, naming constraints, or what happens if the bucket already exists. Given annotations are minimal, the description carries some burden but partially fulfills 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 extremely concise, consisting of two short sentences. It front-loads the primary purpose in the first sentence and adds a valuable usage tip in the second. Every word serves a purpose, with no 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 relatively simple create operation with only two parameters and no output schema, the description covers the essential purpose and the key dryRun behavior. It doesn't elaborate on return values or error handling, but the tool's low complexity and comprehensive schema make this an adequate level of completeness.

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 schema already fully describes both parameters (bucketName and dryRun) with clear descriptions. The description's mention of dryRun=true adds a concrete usage example but not new semantic meaning beyond the schema's definition. With 100% schema coverage, a baseline score 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 action 'Create' and the resource 'Object Storage bucket', which is specific and distinguishes it from sibling tools like 'delete_bucket' or 'list_buckets'. It uses a direct verb+resource structure with no ambiguity.

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 a clear usage hint with 'Use dryRun=true to preview', which tells the agent when to use this parameter for validation without actually creating. It doesn't explicitly exclude alternatives, but for a simple create operation, the context is sufficient and there are no competing create-bucket tools among siblings.

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