lan_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 of behavioral disclosure. The verb 'Get' implies a read operation, but the description does not explicitly confirm read-only behavior, side-effect freedom, or clarify what happens if the device is not found. It lacks any details on permissions, rate limits, or the nature of 'detailed status.'

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, front-loaded sentence with no filler or redundancy. It efficiently conveys the core action and resource, earning its place without unnecessary detail. This is a model of conciseness.

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?

Although the tool has an output schema and only one parameter, the description omits essential usage context such as when to prefer this over lan_device_list, any preconditions (e.g., device must be discovered first), or what the 'detailed status' covers. It is insufficient for an agent to invoke correctly without supplementary guidance.

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 contains one parameter (device_id) with no description, and schema description coverage is 0%. The description fails to mention or explain device_id, its expected format, or how it relates to the status query, thus adding no value beyond the raw 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 identifies the action ('Get') and resource ('detailed current status of a device'), which aligns with the tool name and distinguishes it from sibling tools like lan_device_list or lan_device_control. However, it does not explicitly compare against siblings or clarify what 'detailed' entails, so it lacks definitive differentiation.

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 provides no guidance on when to use this tool versus alternatives such as lan_device_list or lan_device_control. It neither states prerequisites, exclusions, nor typical scenarios, leaving the agent without contextual decision-making information.

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