Unraid API disks

unraid_v4371_query_disks
Read-onlyIdempotent

List attached disks on an Unraid server, excluding serial numbers and geometry details for a simplified drive overview.

TDQS

A4.2/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds useful behavioral context by disclosing that serial numbers and geometry details are intentionally omitted, which informs whether this tool fits a given request. No contradiction with annotations.

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?

The description is a single efficient sentence that front-loads the action and resource. Every word earns its place, with no redundancy or irrelevant detail.

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

Completeness4/5

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

For a zero-parameter, read-only tool with strong annotations, the description gives enough to understand the core operation and an important output constraint. It could say more about the exact shape of the returned list, but the low complexity makes this acceptable.

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?

The tool has zero parameters and the schema is empty with 100% coverage, so there is no parameter burden for the description to carry. Per the baseline for zero-parameter tools, this dimension is well satisfied.

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 uses a specific verb ('List') and resource ('attached disks'), and adds the exclusion of serial numbers/geometry details, which makes the tool's purpose precise. This scope helps distinguish it from the numerous sibling query tools.

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 when this tool is appropriate: when the agent needs attached-disk inventory and not serial numbers or geometry. However, it does not explicitly name alternatives or state when to prefer siblings like unraid_list_disks, unraid_v4371_query_disk, or unraid_v4371_query_assignable_disks.

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