Create Scaleway Object Storage bucket

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

Beyond the annotations, the description adds valuable behavioral context: the bucket is private by default, and the Object Lock create-time flag is silently ignored on Scaleway, requiring a specific post-creation sequence. This discloses a non-obvious platform behavior that annotations alone do not convey.

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 three sentences long and front-loaded with the core action. Every sentence earns its place: the first states what the tool does, the second directs follow-up configuration, and the third warns about the Object Lock limitation.

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 two-parameter creation tool with no output schema, the description is complete. It covers the default state, post-creation configuration path, and a critical platform-specific caveat, giving an agent everything needed to invoke the tool and proceed 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 provides full descriptions for both parameters (bucket and region), including an example and enum values, so the description adds little parameter-level meaning. The 'private by default' note is behavioral rather than parameter-specific, so the baseline of 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 and resource ('Create a new, empty Object Storage bucket') and clearly states the default visibility ('private by default'). It distinguishes from sibling tools by explicitly directing configuration tasks to the scaleway_s3_*_bucket_* config tools, making the creation-focused purpose unambiguous.

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 provides clear context for when to use this tool and what to do afterwards, naming the config tools for post-creation setup and scaleway_s3_enable_object_lock for Object Lock. It does not explicitly state when not to use the tool, but the follow-up guidance effectively differentiates this creation step from configuration and object-lock enabling.

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