create_snapshot_vm

Create a snapshot of a Proxmox VE virtual machine, capturing disk state and optional RAM, to allow recovery and rollback.

Instructions

C2.6/5.0
Behavior2/5

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

No annotations are present, so the description alone must disclose behavioral implications. It only states the action without explaining side effects, such as whether the snapshot includes memory state (vmstate parameter), impact on a running VM, or storage requirements. This is a significant transparency gap.

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

Conciseness3/5

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

The description is a single clear sentence with no wasted words, but it is under-specified for a tool with five parameters. It is concise in form but lacks substance beyond the tool's name.

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

Completeness1/5

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

With 5 parameters, no annotations, no output schema, and no parameter explanations, this one-line description is grossly inadequate. The tool needs context on snapshot behavior, parameter semantics, and preconditions to be safely invoked.

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

Parameters1/5

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

Schema description coverage is 0%, and the description adds no explanation for any of the 5 parameters (node, vmid, snapname, vmstate, description). The name and description do not hint at parameter roles or formats, leaving the schema as the only source, which is insufficient.

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?

The description clearly states 'Create a snapshot of a virtual machine' with a specific verb and resource. It distinguishes this from sibling tools by targeting VMs (as opposed to containers) and by using 'create' rather than list/rollback/delete snapshot operations.

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

Usage Guidelines2/5

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

No guidance is provided about when to use this tool versus alternative snapshot operations (e.g., list_snapshots_vm, rollback_snapshot_vm) or VM management actions. The description gives no context on prerequisites or scenarios where this tool is appropriate.

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