ncloud_databox_list_buckets

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

readOnlyHint=true already tells the agent this is a safe read, so the burden is lowered. The description adds the applicability scope but no behavior beyond that: it does not state whether the listing is region-scoped, account-wide, paginated, or how many results to expect, which matters for a bucket enumeration call.

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?

A single compact sentence with the resource front-loaded and the qualifying scope trailing. Nothing is wasted, though there is no further structure because there is no further content.

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 zero-parameter read-only list tool with annotations covering the safety profile and no output schema to explain, the description supplies what an agent needs to route to it. The only mild gap is the absence of any note on scope/pagination of the returned bucket list.

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 tool takes zero parameters, so the schema has nothing to document and the baseline of 4 applies. There is no parameter nuance the description could or should add.

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?

Specific verb+resource ('List Object Storage buckets') with a scope qualifier that ties it to Data Box import/export, which distinguishes it from the many generic bucket-listing siblings (ncloud_list_buckets, ncloud_ncs_list_buckets, ncloud_datafence_list_buckets). It does not name those siblings explicitly, so the differentiation is implicit rather than explicit.

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 phrase 'usable as Data Box import source / export target' implies the context in which an agent should call this (selecting a source/target before apply_file_import or apply_file_export), but there is no explicit when-to-use statement, no mention of when a different bucket-listing tool is preferable, and no prerequisites.

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