ncloud_ncs_get_bucket_location

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

The readOnlyHint annotation already signals this is a safe read operation, and the description adds useful behavioral details: the underlying endpoint (GET /?location) and the exact return value (LocationConstraint). This is consistent with the annotation and provides concrete expectations beyond what annotations alone convey, but it doesn't discuss potential errors or edge cases, which is acceptable for such a simple read.

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 the service prefix, the action, the endpoint, and an example return value. Every element adds value and there is no fluff. It could be slightly improved by mentioning the sibling for clarity, but it is appropriately concise.

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 read-only, single-parameter tool with no output schema, the description is sufficient. It states what it returns and includes an example, and the annotations cover safety. Nothing critical is missing for an agent to invoke it 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?

The input schema already describes bucketName as 'Name of the Ncloud Storage bucket' with 100% coverage, so the description adds no new parameter meaning. The baseline of 3 applies because the schema fully documents the parameter; the description does not need to repeat it.

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 gets the region of a Ncloud Storage bucket and returns the LocationConstraint (e.g., 'kr'). It names the specific verb and resource, making the purpose unambiguous. However, it does not differentiate itself from the generic sibling ncloud_get_bucket_location, which is a similar operation on a different storage API, so it misses an opportunity to clarify scope.

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?

There is no guidance on when to use this tool versus alternatives such as ncloud_get_bucket_location (generic S3-compatible) or other NCS bucket operations. The description only explains what it does, not the context in which it should be selected. For a tool with many sibling tools, explicit when-to-use guidance is missing.

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