get_volume_qos

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

With no annotations, the description carries the burden, and it does disclose a genuine behavioral trait: some deployments require admin rights, which affects whether the call will succeed. It also implies a read-only listing. It says nothing about ordering, pagination, or empty results, though the output schema covers return shape.

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?

Two short sentences, zero waste, with the what-is-it statement front-loaded ahead of the caveat. Nothing could be cut without losing information.

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 list tool with an output schema and no annotations, this covers the essentials: what is returned and the permission risk. A brief note on how this differs from network QoS policies would close the remaining gap.

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 there are no semantics to explain; the baseline of 4 applies. Nothing in the description is needed or missing on the parameter front.

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?

States a specific verb and resource: 'List Cinder QoS specifications.' The qualifier 'Cinder' implicitly separates it from the sibling get_network_qos_policies, so an agent can distinguish the volume-side QoS lister. It stops short of an explicit contrast statement, keeping it from a 5.

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?

There is no explicit when-to-use or when-not-to-use guidance and no named alternative, even though get_network_qos_policies sits right next to it in the sibling list. The only operational note is 'Cloud policy may require admin rights,' which is a permission prerequisite rather than selection guidance.

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