qemu_vm_start

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

Annotations declare readOnlyHint=false and idempotentHint=false, and the description adds that QMP and the profile's guest TCP network are set up as part of the start. It does not disclose behaviors such as failure when already running, asynchronous completion, or the resulting VM state beyond 'started'.

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 with the action and resource front-loaded. It contains no filler, redundancy, or tangential detail, earning its place entirely.

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 start operation, the core invocation is clear: pass a vm_id and the VM will be started with QMP and its profile network. However, prerequisites, lifecycle relationship to sibling qemu_vm_* tools, and outcome/return behavior are missing, leaving some ambiguity.

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%, and the description does not mention vm_id at all. The schema provides the property name and pattern, but the description adds no meaning beyond what the parameter name already implies.

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 'Start' with the resource 'managed QEMU VM' and adds the details 'QMP' and 'profile's guest TCP network' to characterize the launch mode. It clearly reads as powering on an existing managed VM rather than creating or configuring one, though it does not explicitly name sibling tools.

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?

No when-to-use, when-not-to-use, or alternative tool guidance is provided. The agent is left to infer the difference between this and qemu_vm_create, qemu_vm_restart, qemu_vm_shutdown, and the other qemu_vm_* lifecycle tools based only on the verb.

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