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

With no annotations present, the description carries the full behavioral burden. It discloses the supported algorithms, explicitly calls out unsupported key types (customer-managed keys, aws:kms:dsse), and states the post-condition for new objects. Minor gaps remain, such as whether an existing encryption configuration gets overwritten and any permission requirements, but the provided behavior is substantive and accurate.

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 tight sentences with no fluff. It front-loads the service and action, follows with the API path and supported values, and then explains the behavioral effect. Every clause contributes information an agent needs.

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 2-parameter PUT operation with no output schema, the description is close to complete: it covers what to pass, which values are valid, what is unsupported, and the effect on new objects. It could mention that the operation replaces or overwrites the existing encryption rule and that it returns a standard response, but these are minor given the tool's simplicity.

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 already covers both parameters at 100%, so the baseline is 3. The description adds value by expanding on sseAlgorithm: it explains that aws:kms uses a Ncloud-managed key and clarifies which algorithm variants are not supported, going beyond the raw enum. bucketName is straightforward and needs no extra elaboration.

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 states a specific verb (Set) and a specific resource (default server-side encryption for a Ncloud Storage bucket), and reinforces it with the API path 'PUT /?encryption'. This unambiguous action clearly distinguishes it from sibling operations like get_bucket_encryption and delete_bucket_encryption without needing to name them.

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 conveys clear usage context: if you want to set default server-side encryption on a bucket, this is the tool. It does not explicitly name alternatives or exclusions, but the action and the effect statement 'New objects are encrypted with it by default' make the applicable scenario clear.

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