get_witzense_device_locations

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states the action and resource, but does not clarify whether this is a read-only operation (though likely implied by 'get'), any authentication requirements, potential rate limits, or what happens when multiple IMEIs are passed. The lack of such detail reduces transparency.

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?

A single sentence that is direct, front-loaded, and free of filler. Every word contributes to understanding the core purpose. This is an appropriately minimal description.

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 tool's simplicity (2 optional params, no output schema), the description is minimal but incomplete for effective use. It lacks usage context, expected return shape, or any behavioral notes. The absence of alternative guidance and behavioral transparency makes it incomplete despite low complexity.

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 covers both parameters with descriptions (100% coverage), so the description adds no additional meaning. Per guidelines, baseline is 3 when schema coverage is high. The tool description does not clarify parameter formats or behavior beyond what the schema already provides.

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 the tool's function: 'Get the latest location for one or more Witzense devices.' It uses a specific verb ('Get') and resource ('latest location'), and conveys the scope (one or more devices). This distinguishes it from sibling tools like get_witzense_tag_location (single tag) or get_witzense_track (tracking 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 offers no guidance on when to use this tool versus alternatives. With 22 sibling tools covering various Witzense functions (tracks, reports, geofences, etc.), the agent receives no context about when this is the right choice. It neither mentions alternatives nor provides any selection criteria.

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