ncloud_ncs_get_bucket_encryption

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

The annotations already provide readOnlyHint: true, indicating this is a safe read operation. The description adds the specific resource (encryption configuration) but does not disclose any additional behavioral aspects, such as what happens if the bucket has no encryption configured (e.g., returns empty vs. error) or any permission requirements. Since the annotation covers the read-only nature, the description does not contradict it but also does not enrich the agent's understanding beyond the annotation.

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 immediately states the tool's purpose. It is front-loaded with the action and resource, includes the API path for reference, and contains no filler. Every word earns its place, making it easy for an agent to parse quickly.

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 simple retrieval tool with one parameter and a read-only annotation, the description is largely complete. It does not mention what the response will contain (e.g., the structure of the encryption configuration or what happens when no configuration exists), but given the lack of an output schema, this is a minor gap. The agent can infer the likely response from the tool's name and the GET operation, so the description is sufficient for straightforward use.

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 has 100% coverage: the only parameter, bucketName, is described as 'Name of the bucket to retrieve encryption configuration for'. The description does not add any extra meaning about the parameter, such as format, constraints, or examples. Given the high schema coverage, the baseline of 3 is appropriate; the description does not need to compensate.

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 ('Get') and the specific resource ('default server-side encryption configuration of a Ncloud Storage bucket'), and it includes the underlying API endpoint (GET /?encryption). It is unambiguous and distinct from sibling tools that retrieve other bucket configurations (versioning, lifecycle, CORS) or modify encryption.

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 does not explicitly mention when to use this tool versus alternatives. However, the purpose is self-evident: if you need to retrieve a bucket's encryption configuration, this is the tool. There is no guidance on exclusions, prerequisites, or when a different tool (e.g., put_bucket_encryption) would be more appropriate. The usage context is implied by the name and purpose rather than stated.

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