toggle_device

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It only states the basic action of toggling a device on/off, but does not disclose potential side effects, return value, error conditions, or behavior when the device is already in the desired state. This is a minimal level of transparency.

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?

The description is extremely concise: a single sentence for the action followed by parameter explanations. Every word earns its place, and the structure is front-loaded with the purpose. There is no redundancy or filler.

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 simple tool with two required integer parameters, the description provides enough information to invoke it correctly. It explains the action and the meaning of each parameter. However, without an output schema, it does not specify what the tool returns after toggling, but this is minor for a state-changing operation. The lack of return information and error handling nuances prevents a perfect score.

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 input schema only provides parameter names and types, with no descriptions. The description adds meaningful context by explaining track_index as 'the index of the track containing the device' and device_index as 'the index of the device on the track.' This helps the agent understand the hierarchical relationship, adding value beyond the schema.

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 clearly states the tool's function with a specific verb+resource: 'Toggle a device on or off.' This distinguishes it from sibling tools like move_device_left, delete_device, and get_device_parameters, which perform different actions on devices.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of scenarios where toggling is appropriate, or exclusions compared to other device manipulation tools. The description simply states the action without contextual usage advice.

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