ncloud_get_bucket_location

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

Annotations already provide readOnlyHint: true, so the agent knows this is a safe read. The description adds no additional behavioral context beyond clarifying the term 'location constraint'. It does not disclose edge cases or permission requirements, but with annotations covering the safety profile, a 3 is appropriate.

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, concise sentence that conveys the essential purpose with no redundant words. It is front-loaded and easy to parse.

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 (one parameter, read-only, no output schema), the description is complete enough. It clearly indicates the return concept (the region) and does not require additional detail. However, a brief note on return format could have made it a 5, but it is not necessary.

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% and the bucketName parameter already has a clear description. The tool description adds the parenthetical 'location constraint' but does not provide additional syntax or formatting details beyond what the schema already conveys, so the baseline 3 applies.

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 'Get' and the resource: 'region (location constraint) of an Object Storage bucket'. It is specific and distinct from sibling tools like get_bucket_acl or get_bucket_versioning, making the tool's purpose immediately clear.

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 context is straightforward: this tool is for retrieving a bucket's region. No exclusions or alternatives are mentioned, but for a simple getter, the intended use is unambiguous and does not require contrast with siblings.

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