List Unraid virtual machines

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

Annotations already declare readOnly, idempotent, and non-destructive behavior. The description adds the output field scope (IDs, names, lifecycle states) but gives no further behavioral context such as ordering, filtering, or relationship to the query_vms sibling. No contradiction with annotations exists.

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 that is specific and front-loaded with the action and resource. Every phrase adds value by enumerating the returned fields, with no affiliation or repetition.

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 operation with safety annotations already provided, this description is nearly complete. It states the core output fields despite the absence of an output schema, but it would be slightly more complete if it distinguished itself from the similarly scoped unraid_v4371_query_vms sibling.

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 accepts zero parameters, and the schema fully documents this with 100% coverage. The description's mention of IDs, names, and lifecycle states refers to output rather than parameters, so there is nothing missing for the agent to invoke the tool correctly.

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 identifies a specific verb ('List'), a specific resource ('Unraid virtual machines'), and the exact output fields ('IDs, names, and lifecycle states'). It is clearly distinct from list tools for other resources like disks or Docker containers, though it does not differentiate itself from the similar sibling unraid_v4371_query_vms.

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 does not state when to prefer this tool over alternatives, and the sibling list includes unraid_v4371_query_vms which may overlap significantly. There is no mention of when to use this tool versus query-style VM tools or any exclusions.

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