connect_device

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'connect' without explaining potential side effects (e.g., whether it establishes a persistent connection, what happens if already connected, or if any device state changes). This is a significant gap for a mutating action.

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 a single, focused sentence that conveys the essential purpose. It contains no filler or redundant information, making it highly concise and well-structured.

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?

The tool is simple with one parameter, but there is no output schema and the description does not explain the return value or behavioral outcomes. It also lacks information about prerequisites or side effects. Given the context of sibling tools, the description gives the gist but is not fully complete.

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 description coverage is 100% for the single parameter deviceId, which already explains it as 'The unique identifier of the device to connect'. The tool description adds 'by ID' but no additional semantic detail beyond what the schema provides. Baseline 3 is appropriate.

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 action ('Connect'), the resource ('a specific hardware device'), and the scope ('by ID'). It is easily distinguished from siblings like list_devices, disconnect_device, and device_status, which serve different purposes.

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 verb 'connect' implies the intended use, but the description provides no explicit guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., device must be listed), nor does it suggest using list_devices first or using execute_command after connecting. Usage is implied rather than clearly stated.

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