Set Scaleway bucket visibility (public/private)

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

Annotations indicate readOnlyHint=false, openWorldHint=true, idempotentHint=true, destructiveHint=false. The description aligns with these: it reveals that setting public-read grants anonymous read access to all objects (a significant behavioral detail), that confirm=true is required, and that private restores owner access. No contradictions.

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 two sentences long, front-loading the core purpose and then efficiently adding the most critical behavioral notes (confirm requirement, sibling tool mention). Every sentence adds value without redundancy.

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?

Despite having no output schema, the description combined with annotations covers: what the tool does, when to use it vs. alternatives, parameter meanings, required confirm flag, and behavioral impact. The sibling list is large but the description explicitly disambiguates from the most relevant alternative (bucket policy tool). Complete for this tool's complexity.

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 schema covers 75% of parameters with descriptions. The description adds semantic value by clarifying what the two enum values actually do ('public-read' grants anonymous internet read, 'private' restores owner-only access) and by explaining the confirm parameter's required=True constraint when visibility=public-read. The region parameter's default is mentioned in schema but not description; still, the added value is strong.

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 (set visibility via canned ACL), the resource (bucket), and the specific settings (public-read/private). It explicitly calls out the sibling tool scaleway_s3_put_bucket_policy as the finer-grained alternative, which helps disambiguate from similar S3 tools in the sibling list.

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 explicit usage context: it describes when to use the tool (set visibility via canned ACL), includes a warning about the confirm=true requirement for public-read, and names the more granular alternative (scaleway_s3_put_bucket_policy). This enables the agent to make informed decisions.

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