Set Scaleway bucket website configuration (full replace)

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

The description adds meaningful behavioral details beyond annotations: 'FULL-REPLACE', the requirement of confirm=true because 'this publishes an HTTP website endpoint', the endpoint naming pattern, and the dependence on visibility for anonymous access. This goes beyond readOnly/destructive/idempotent hints, telling the agent what happens in the real world. No contradiction with annotations.

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?

Three compact sentences with the core function first, then the confirmation requirement, then the operational context. Every sentence adds relevant information without boilerplate, making it easy for an agent to scan.

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 5-parameter mutation tools with no output schema, the description covers the core purpose; full-replace side effect, publication risk, confirm requirement, endpoint naming, and a dependency on bucket visibility. It could optionally mention how to verify with the get_bucket_website sibling, but the provided context is sufficient for safe invocation.

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%, so parameters are already well documented. The description adds semantic value by explaining that confirm=true is required because the operation publishes an HTTP endpoint, and characterizes index_document/error_document roles ('index document, optional error document'). This is baseline-plus.

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+resource: 'Configure the bucket for static-website serving (index document, optional error document).' It clearly distinguishes this PUT operation from sibling tools like scaleway_s3_get_bucket_website and scaleway_s3_delete_bucket_website by naming the configuration action and adding the FULL-REPLACE warning.

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 gives clear situational context: the tool publishes an HTTP website endpoint, requires confirm=true for that reason, and notes that anonymous access depends on bucket visibility with an explicit cross-reference to scaleway_s3_set_bucket_visibility. It does not explicitly contrast with when to use get/delete website variants, but the usage intent is well understood.

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