turn_off

Turn off any SwitchBot Plug Mini or Bot set to switch mode. Use it to remotely power down connected devices through Switchr MCP Server.

Instructions

Turn off a SwitchBot Plug Mini or a Bot in switch mode.

TDQS

A3.5/5.0
Behavior3/5

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

With no annotations, the description carries the full burden of behavioral disclosure. It names the supported device types, which is useful, but it does not reveal consequences like idempotency, error behavior, or what happens when the device is already off.

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, front-loaded sentence with no wasted words. It efficiently conveys the action and the target devices.

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?

This is a minimal command tool with one parameter and no output schema, so a short description is somewhat acceptable. However, it lacks information about return values, failure modes, or the expected outcome when the command cannot be executed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the schema already defines deviceId as 'Device ID or device name'. The description adds no parameter semantics beyond what the schema provides, so the baseline 3 is appropriate.

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 states a specific action ('Turn off') and identifies the exact resources ('SwitchBot Plug Mini' or 'Bot in switch mode'). This clearly distinguishes it from siblings like turn_on and press_bot.

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

Usage Guidelines2/5

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

No explicit guidance is given about when to use this tool instead of alternatives such as turn_on or press_bot. The supported device types are implied, but no exclusions or prerequisites like device status are mentioned.

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