backup_list

Read-only

List Proxmox backup archives by storage, with optional VM ID filtering to locate guest backups.

Instructions

[READ] List backup archives on a storage (optionally filtered by vmid).

Args: storage: Storage id to list backups from. vmid: Optional guest id filter. target: Proxmox target name from config. node: Node name; omit to use the configured default node.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

A3.8/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds a useful behavioral detail — omitting node falls back to the configured default — but says nothing about return format or pagination behavior for a listing tool.

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

Conciseness4/5

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

The purpose is front-loaded in the first sentence and the Args block is terse per-item. Slightly verbose in repeating the frame, but every line contributes meaning.

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

Completeness3/5

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

With no output schema and only a readOnlyHint annotation, the description should ideally sketch what a listing returns, and it does not. It fully covers inputs, but leaves the return shape and filtering/response semantics unstated.

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 description coverage is 0%, so the description carries the full burden and does so well, documenting all four args: storage (storage id), vmid (optional guest filter), target (Proxmox target from config), and node (with the default-fallback rule). Format details are still thin, but each parameter's meaning is clear.

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?

States a specific verb (List) and resource (backup archives) with explicit scope (on a storage, optionally filtered by vmid). The [READ] tag and the storage/vmid scope make it easy to distinguish from vm_backup (creation) and backup_restore.

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

Usage Guidelines3/5

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

The description implies the read/list use case and the optional vmid filter, but it never names alternatives or states when to prefer this over backup_restore or storage_content, both of which appear in the sibling list and also surface storage/backup data.

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