get_device_status

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

No annotations are provided, so the description carries the full behavioral burden. It states the tool reads status (a read operation) but does not explicitly disclose non-mutating behavior, permission/auth requirements, or what happens when the deviceId is invalid/unreachable. The device-type-specific output enumeration adds useful context, but for a tool without annotations there is room to more explicitly signal that this is a safe read 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?

The description is a single, dense sentence that efficiently packs the tool's purpose and device-type-specific outputs. Every clause adds value—the device-type enumeration distinguishes result shapes without waste. No filler or redundancy.

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?

With one parameter, 100% schema coverage, and a good output enumeration, the description is mostly adequate. However, there is no output schema, and for a read tool the description could have disclosed the response format or behavior on invalid device IDs. Given the device-type diversity (thermostats, plugs, purifiers), a note on which device types are unsupported or the error behavior for unknown IDs would improve completeness.

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%—the single parameter (deviceId) is well documented in the schema as 'Device ID (MAC) or nickname of the device.' The description adds context about what the tool returns but doesn't add parameter-level meaning beyond the schema. With full schema coverage, 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 uses a specific verb+resource ('Get detailed status') and clearly identifies the resource (Wyze device). It distinguishes itself from siblings by enumerating device-type-specific return data: temperature/humidity/setpoints for thermostats, on/off for plugs/switches, AQI and fan mode for air purifiers. This clearly separates it from the control_* sibling tools in the list.

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 implies it should be used to inspect device status, and the device-type-specific output lists hint at when each result would be relevant. However, it lacks explicit when-to-use guidance relative to alternatives—such as clarifying that this is the read-only counterpart to the control_* tools, or when get_api_status (a sibling API-level tool) would be more appropriate versus this device-level tool.

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