Get device status

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

With no annotations provided, the description carries the full burden for behavioral disclosure. It does reveal that the output is 'decoded' and comprehensive, but it does not mention side effects, failure behavior for unknown devices, offline devices, or whether the read is live or cached. 'Return' suggests a safe read, but that is implicit rather than stated.

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, well-structured sentence that front-loads the action and resource, then efficiently lists the status fields. There is no fluff or redundant repetition of schema information.

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 description adequately explains what the tool returns, which matters since there is no output schema. However, it does not state that at least one of mac or name should be supplied, what happens when neither is provided, or how errors like an unknown device are handled. These gaps make it minimally viable but 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%, with both mac and name already clearly explained. The description adds no additional parameter-level guidance beyond the notion of operating on 'one device', so the baseline score of 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 ('Return') and a specific resource ('full decoded status of one device'), and enumerates the included fields. This clearly distinguishes it from sibling tools like list_devices (which lists devices) and the set_* tools (which are mutations).

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 phrase 'one device' implies this is for retrieving the status of a single device, and the sibling set_* tools imply that this is the read counterpart. However, there is no explicit statement about when to use this tool versus alternatives such as list_devices or get_room_temperature, nor any qualification about selectors being required.

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