timeweb_list_s3_storages

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states that it lists storages, without mentioning pagination behavior, permissions, or output structure. The presence of limit/offset parameters suggests pagination, but this is not disclosed, and 'List all' could be misleading given the pagination parameters.

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 a single sentence, front-loaded with the verb and resource, and contains no filler or redundant information. It is concise and immediately clear.

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 simple read-only list tool with three optional parameters and full schema coverage, the description is minimally adequate. However, it omits useful context about pagination (how limit/offset interact) and the return format (markdown vs json), which leaves some gaps for an agent trying to invoke the tool effectively.

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 100%, with each parameter (limit, format, offset) already having clear descriptions. The tool description adds no additional meaning beyond what the schema provides, so the baseline score of 3 is appropriate.

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 the specific verb 'List' and the resource 'S3-compatible object storages' with scope 'in the account'. This clearly distinguishes it from sibling tools like create_s3_storage, delete_s3_storage, and especially list_s3_presets, which lists presets rather than actual storages.

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 this tool is used to enumerate all S3 storages, but it provides no explicit when-to-use guidance or mention of alternatives. Sibling tools that create or delete storages are not referenced, leaving the agent to infer the appropriate context from the operation name alone.

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