move_vm_disk

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

No annotations are provided, so the description must disclose behavioral traits. It fails to mention the 'delete' parameter's default behavior (source deletion), potential need to stop the VM, or other side effects of moving a disk.

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?

A single sentence that is direct and without redundancy. It communicates the core action efficiently.

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 tool with 5 parameters, no output schema, and no annotations, this minimal description is insufficient. It omits prerequisites, the effect of the 'delete' flag, return values, and error conditions.

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 has zero descriptions for its 5 parameters. The description only hints at 'storage pool' as the destination but does not explain the 'disk' selector, 'node', or the 'delete' flag, leaving key parameters ambiguous.

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 a specific verb ('Move') and identifies the resource ('virtual machine disk') and destination ('different storage pool'), clearly distinguishing it from sibling tools like resize_vm_disk or add_vm_disk.

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 implies the tool is for relocating a VM disk to another storage pool but provides no explicit context on when to prefer it over alternatives like migrate_vm or how it fits into VM management workflows.

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