pve_disk_move

Move a guest disk to another storage. Dry-run shows source→target plan; set confirm=true to execute. Use delete_source with caution as it removes the original copy.

Instructions

MUTATION: move a guest disk to another storage. Dry-run by default — the PLAN shows source->target and whether the source copy is deleted (delete_source=True is HIGH, no easy undo). confirm=True to execute. Async — returns a task UPID (poll with pve_task_status). To grow a disk in place instead of relocating it use pve_disk_resize.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
diskYesDisk key to move, e.g. `scsi0` or `rootfs`.
kindNoGuest type: `lxc` for a container or `qemu` for a VM.lxc
nodeNoPVE node the guest runs on. Omit to resolve it automatically from the cluster.
vmidYesNumeric ID of the guest — VMID for a QEMU VM or CTID for an LXC container.
confirmNoLeave `false` (default) to get a dry-run PLAN; set `true` to execute the move.
delete_sourceNoIf true, delete the source copy after the move (HIGH risk); if false (default), keep it.
proximo_targetNoWhich configured Proxmox target to run this call against — a target name from your multi-target config (a specific PVE/PBS/PMG/PDM box). Omit to use the single/default target from the environment; the selection applies only to this call.
target_storageYesStorage backend name to move the disk to.

Behavior5/5

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

Despite no annotations, the description fully discloses mutation, dry-run mode, async behavior returning a task UPID, and the high risk of delete_source=True. This is comprehensive behavioral disclosure.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences with no wasted words. Critical information is front-loaded: purpose, mutation flag, dry-run default, risk factors, async behavior, and alternative tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With output schema present and complex behavior (8 params, async, mutation), the description covers all essential aspects: what it does, how to use safely, async return, and alternative. No gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description adds process-level context (PLAN, confirm flow) that enhances understanding beyond schema. Does not detail every parameter, but the schema already covers that.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states 'move a guest disk to another storage' and distinguishes from sibling pve_disk_resize. The verb 'move' and resource 'guest disk' are specific and unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly explains dry-run by default with confirm=True to execute, and contrasts with pve_disk_resize for disk growth. Provides clear when-to-use and when-not-to-use guidance.

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