QEMU monitor command

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

The description adds a 'MEDIUM RISK' warning, which provides some behavioral insight beyond annotations. However, it does not detail potential side effects, data integrity risks, or required permissions. Annotations already indicate non-readonly and open-world, so the risk label adds moderate value.

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 short and front-loaded with the purpose, followed by examples and a risk note. Every sentence serves a purpose with no redundancy. It could be slightly more structured but is effective.

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?

Given the complexity of an arbitrary command execution tool with no output schema, the description is minimal. It covers purpose and risk but lacks information on return values, error handling, or authorization requirements. Adequate but not complete for safe usage.

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?

Only the 'command' parameter is described in the schema. The description gives examples but does not explain 'node' or 'vmid', which remain undocumented. With only 33% schema coverage, the description should add meaning for the missing parameters but fails to do so.

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 'Run an arbitrary QEMU monitor command' with specific verb and resource. It provides examples that illustrate typical commands. However, it does not explicitly differentiate from similar sibling tools like vm_agent_exec or vm_sendkey, which are more focused.

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 explicit guidance on when to use this tool versus alternatives. The examples imply it's for arbitrary QEMU monitor commands, but no exclusion of cases where other VM command tools are more appropriate, nor any mention of prerequisites or context.

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