oci_os_create_bucket

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

No annotations are provided, so the description carries the full burden. It does not disclose any behavioral traits such as side effects (creating a resource), required permissions, reversibility, or return values. The description essentially restates the tool name without adding meaningful context.

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 sentence with no unnecessary words. It is front-loaded and to the point, conveying the core purpose efficiently.

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?

With no output schema and no annotations, the description should explain what the tool returns, how it behaves, and what the parameters mean. It only states the action, omitting crucial context like the default compartment behavior, the impact of different storage tiers and public access settings, and any expected output. This is insufficient for a create operation with four parameters.

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 50% – bucket_name and compartment_id have descriptions, but storage_tier and public_access only have enums. The tool description adds no parameter information, failing to explain the meaning of storage tiers or public access options, and thus does not compensate for the missing parameter descriptions.

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 specific verb 'Create' and the resource 'Object Storage bucket', distinguishing it from sibling tools like oci_os_list_buckets, oci_os_delete_bucket, and oci_os_get_namespace. It is unambiguous and specific.

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 usage is implied by the verb 'Create' – one would use this tool when they need to create a bucket. However, there is no explicit guidance on when to use it vs alternatives, prerequisites (e.g., namespace, permissions), or exclusions. The description only states what the tool does.

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