ring_get_device_status

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

With no annotations provided, the description carries the behavioral disclosure burden. It clearly indicates a read-only operation ('Retrieve') and specifies that the data is real-time, which informs the agent that live device data will be fetched. The lack of explicit side-effect disclosure is acceptable because the act of retrieving status inherently signals a non-mutating 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, direct sentence that front-loads the primary action and resource. Every element is informative, with no filler or repetition of schema details.

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 one-parameter getter with no output schema, the description is largely complete: it names the action, the target, the key return fields, and the accepted lookup method (ID or name). It does not mention error conditions or what happens when the device is not found, but given the low complexity and the schema's coverage of the parameter, this is a minor gap.

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 already documents the sole parameter fully, including its type, requirement, minLength, and examples of accepted name substrings. The description adds 'by ID or name' context, but this is already covered by the schema description. With 100% schema coverage, the baseline 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 states a specific verb ('Retrieve') with a clear resource ('Ring device status') and lists the exact data points returned (battery, Wi-Fi RSSI, firmware version). It differentiates from sibling tools by focusing on device status rather than list, capabilities, configurations, streaming, or event history.

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 makes it clear this is for retrieving real-time status data from a device, which implies the context for use. However, it does not explicitly state when to use this tool versus alternatives such as ring_list_devices (for finding device IDs) or ring_get_device_capabilities (for feature capabilities). No exclusions or alternative conditions are provided.

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