get_device_vpn

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

No annotations are provided, so the description carries the full disclosure burden, yet it says nothing about permissions, whether the data is live or configured, error behavior for unknown devices, or what the 'configuration' contains. Only the weak implication of 'Get' suggests a read-only operation.

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 front-loaded sentence with zero redundancy. It is appropriately tight, though the brevity leaves room for one clarifying clause at no structural cost.

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 low-complexity single-parameter read tool the definition is minimally viable, but with no annotations and no output schema the description never indicates what a 'VPN configuration' response contains or what happens on a bad device_id.

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?

Schema coverage is 100% and the single device_id parameter is fully documented in the schema (ID or system-ip), so the description does not need to restate it. Baseline 3 applies since the schema does the heavy lifting.

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?

The description states a specific verb and resource ('Get VPN configuration') plus the target scope ('for a device'), so an agent knows exactly what it retrieves. It does not differentiate itself from any sibling, though none of the listed siblings is a close VPN-config analogue.

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 description offers no guidance on when to use this versus other device-scoped tools (e.g. get_device_details or get_device_interfaces), no prerequisites, and no exclusions. Usage must be inferred entirely from the name.

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