qnap_system_info

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

No annotations are provided, so the description carries the full burden. It clearly indicates a read-only operation via 'Get' and lists the returned fields, but does not disclose potential error conditions, authentication needs, or whether it queries the device live. Adequate for a simple info tool but not thorough.

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 with no redundant wording. The action and key output fields are front-loaded, making it easy to scan.

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 one-parameter, no-output-schema tool, the description is nearly complete: it states the purpose and the primary data fields returned. It lacks explicit return format or error handling, but the simplicity of the tool makes this a minor gap.

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?

The schema fully documents the only parameter (device_id) with a description, and the tool description adds no extra parameter semantics. Baseline 3 is appropriate as the description does not enhance understanding of the parameter.

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?

Description clearly states the tool retrieves QNAP NAS system information with specific fields (model, firmware, uptime). It is distinct from other QNAP tools like qnap_get_volumes or qnap_get_disks, but does not explicitly differentiate from qnap_resource_usage or synology_system_info, so a 4 is appropriate.

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 purpose implies when to use this tool (when needing system-level info), but there is no explicit guidance on when not to use it or which alternative to choose for other system details. It provides minimal context for an agent to select this over sibling tools.

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