arcane_list_volume_backups

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

With no annotations, the description carries the full behavioral burden. It only says 'List backups for a volume' and does not disclose what is returned, whether ordering or pagination exists, or any potential side effects. Since it's a read operation, there are no destructive traits, but the description adds no context beyond the basic action.

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, concise sentence that is front-loaded with the primary action and resource. It is appropriately sized for a simple list operation, though it could be slightly expanded to include return value context.

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 list tool with no output schema, the description gives the core purpose but omits details about the return format or any filtering options. Given the low complexity and full schema coverage, it is minimally viable, but additional context on what constitutes a 'backup' or how they are listed would improve completeness.

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 input schema covers 100% of the parameters, providing descriptions for both 'volumeName' and 'environmentId'. The tool description does not add additional semantics, but the schema is sufficient, so this meets the baseline for high schema coverage.

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 ('List') and resource ('backups for a volume'), which distinguishes it from sibling tools like create/restore backups and list_volumes. However, it omits the context of environmentId, which is a required parameter, but the schema provides that detail.

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 provides no guidance on when to use this tool versus alternatives. It does not mention exclusions, prerequisites, or reference any sibling tools. The usage context must be inferred solely from the tool name and description.

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