vyos_poweroff

Power off a VyOS router immediately. This action shuts down the system, requiring physical or out-of-band access to restore power. Use for emergency or scheduled shutdown.

Instructions

Power off the VyOS router immediately.

WARNING: This will shut down the router. The router will
need physical or out-of-band access to power back on.

No arguments

Behavior5/5

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

Clearly states 'shut down the router' and the irreversible nature of the action (needs physical access to restart). No annotations provided, but description fully discloses the destructive behavior.

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?

Two sentences: first states the action, second provides critical warning. No unnecessary words, front-loaded with key information.

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

Completeness5/5

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

For a simple tool with zero parameters and no output schema, the description covers what the tool does and the essential safety warning. Complete and sufficient.

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?

No parameters exist, so baseline 4 applies. Description does not need to add parameter information.

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?

Explicitly states 'Power off the VyOS router immediately' with a clear verb and resource. Distinguishes from related tools like vyos_reboot (restart) and vyos_reset (reset).

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

Usage Guidelines4/5

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

Includes a warning that physical or out-of-band access is needed to power back on, implicitly guiding when to use (only with such access). Could explicitly mention not to use if remote recovery is required, but the warning effectively sets usage boundaries.

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