get_device_status

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

With no annotations, the description carries full responsibility for behavioral disclosure. It only conveys a read-like operation ('Get') but does not confirm safety (e.g., no side effects), authentication needs, or other behavioral traits. The minimal description is insufficient for an agent to assess risks or side effects.

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 front-loads the core purpose without extraneous information. It is appropriately concise for a simple tool, though it could benefit from slightly more contextual detail without sacrificing brevity.

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?

Given the lack of an output schema, the description should elaborate on what 'full status' includes, especially since siblings offer granular reads. It does not specify return values, pagination, or the default host behavior. With many sibling tools, more contextual guidance is needed for effective selection.

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 fully documents the only parameter ('host') with a description and default value. The tool description adds no additional parameter-level meaning beyond the schema. With 100% schema coverage, the baseline of 3 is appropriate, as the description does not enhance parameter understanding.

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 'Get full status of the home air conditioner device', specifying a distinct resource ('full status') that differentiates it from siblings like get_humidity and get_temperatures which target specific metrics. However, it doesn't explicitly contrast with those tools, leaving some ambiguity about what 'full status' entails.

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?

No guidance is provided on when to use this tool versus alternatives such as get_humidity or get_temperatures. The description does not include any explicit when-to-use or when-not-to-use instructions.

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