get_volume

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

Annotations already declare readOnlyHint=true and idempotentHint=true, so the read-only and repeatable nature is covered. The description adds a modest behavioral detail by promising 'full detail' and qualifying the volume as 'standalone', but it does not describe response contents, error behavior, or any further runtime characteristics. This is sufficient but not rich.

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, front-loaded sentence with no filler. Every word earns its place: it specifies the action, scope, target, and required input in under 10 words.

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 one-parameter read-only tool with annotations covering safety and idempotency, the description is nearly complete: an agent knows what to call and with what input. The only gap is that it does not hint at the response shape, but full detail' implies a comprehensive return and no output schema exists to enumerate. Slight improvement would be naming alternatives, but that is already handled under usage guidelines.

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 0%, so the description must compensate. It does partly by tying the parameter to a volume id ('by its id'), but the schema property is already named volume_id with title 'Volume Id', so the added meaning is minimal. No format, source, or uniqueness details are given.

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 names a specific verb ('Get'), an explicit resource ('full detail for one standalone volume'), and the identifying mechanism ('by its id'). It clearly distinguishes from siblings like list_volumes (which lists multiple volumes) and get_volume_task_status (which reports task progress), so an agent can infer exactly what this tool does.

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 a clear context: use it when you need full details for a single volume and you have its id. However, it does not explicitly mention alternatives such as list_volumes for overviews or get_volume_task_status for ongoing operations, leaving the when-not-to-use guidance implied rather than stated.

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