Set Scaleway bucket encryption config

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

Annotations already indicate idempotentHint=true and destructiveHint=false, so the description does not need to repeat those. The description adds valuable behavioral context beyond the annotations: it verifies that the setting is real and visible in the console, confirming it takes effect immediately. This goes beyond what structured metadata provides.

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?

Two sentences, first states purpose, second adds verification detail. No fluff, front-loaded with the key action. Every sentence earns its place.

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?

This is a simple set operation with few parameters and no output schema. Annotations cover safety and idempotency. The description provides the action, the specific algorithm, and verification in the console. It is complete for an agent to use correctly without further elaboration.

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 67% (bucket and region have descriptions; algorithm has a const but no description). The description reiterates AES256 but adds no additional info for bucket or region. The schema already covers the essentials, so the description provides minimal added value for parameters.

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 the bucket's S3 default-encryption configuration (AES256)'. This is specific with verb + resource + configuration detail. It distinguishes from sibling tools like get_bucket_encryption and delete_bucket_encryption by naming the 'set' operation and the encryption algorithm.

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 implies when to use this tool (to set default encryption) but does not explicitly mention alternatives or when not to use it. However, the context from sibling tools (get/delete encryption) and the tool's name is clear enough for an agent to infer appropriate usage. The live-verification note adds confidence in using it.

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