ncloud_put_bucket_acl

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

Annotations are empty, so the description carries the full burden of behavioral disclosure. It states it 'sets' an ACL but does not mention whether this overwrites existing ACLs, requires specific permissions, is reversible, or what happens if the bucket does not exist. No side effects or prerequisites are disclosed.

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 front-loads the verb and resource. No redundant or filler information is present.

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?

This is a simple two-parameter tool with complete schema and a clear description. However, the lack of behavioral context (permissions, side effects, return behavior) and absence of an output schema mean the agent is not fully informed about consequences, making it adequate but with gaps.

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 description coverage is 100%, with both bucketName and acl fully described. The description adds minor clarification (canned ACL, Object Storage bucket) but does not provide meaningful semantics beyond what the schema already offers. Baseline 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 uses a specific verb 'Set' with a clear resource 'access control list of an Object Storage bucket' and method 'using a canned ACL'. This clearly distinguishes it from sibling tools like get_bucket_acl and put_object_acl.

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 state when to use this tool versus alternatives. Usage is implied by the resource type (bucket ACL), but there is no mention of get_bucket_acl for reading or put_object_acl for object-level ACLs. Provides minimal guidance beyond the action itself.

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