object_storage_list_buckets

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

No annotations are provided, so the description carries full burden. It only states the basic function with no disclosure of side effects (none expected), rate limits, required permissions, or behavior on error (e.g., invalid region). Lacks transparency beyond surface operation.

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?

Description is a single, short sentence with no redundant information. Every word is necessary and front-loaded. Ideal conciseness.

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 simplicity of the tool (one optional parameter, output schema present), the description is minimally adequate. However, it does not explain default behavior for region or provide guidance on selecting among sibling tools. Could be more complete for an AI agent.

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% with a clear description for the single 'region' parameter. The tool description does not add any additional meaning beyond the schema, which is acceptable but does not enhance understanding.

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?

Description explicitly states 'List Object Storage buckets in a region', using a specific verb and resource. It clearly distinguishes from sibling tools like object_storage_list_objects (lists objects) and object_storage_create_bucket (creates a bucket).

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?

No explicit guidelines on when to use vs. alternatives. The description implies usage for listing buckets, but lacks prerequisites (e.g., required permissions) or context about when not to use it. Sibling distinctions are only implicit via naming.

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