get_witzense_mileage

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

No annotations are provided, so the description must carry the full behavioral burden. It only states 'Get mileage trip data', offering no details on pagination (despite page_size and start_row parameters), default IMEI behavior (though the schema mentions it), or any read-only or side-effect implications. This is a significant gap for a data retrieval tool.

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 sentence and is concise, but it is under-specified. There is no fluff, but the brevity undermines usefulness. It is appropriately front-loaded but lacks substantive content that would earn a higher score.

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 has 5 parameters, no output schema, and no annotations, the description is far too sparse. It does not explain what 'mileage trip data' includes, how to interpret results, or any edge cases. The context is incomplete for an agent to fully understand the tool's behavior.

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 only 20% (only imeis has a description). The description adds no clarification for begin_time, end_time, page_size, or start_row. With low schema coverage, the description should compensate, but it does not, leaving the agent to infer from names alone.

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 action 'Get' and the resource 'mileage trip data' with a scope of 'one or more devices'. While it distinguishes the general topic from siblings like get_witzense_track or get_witzense_trips_report, it does not explicitly differentiate itself, so it falls short of a 5.

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?

There is no mention of when to use this tool versus alternatives like get_witzense_trips_report or get_witzense_device_locations. The description provides no contextual cues for when this tool is appropriate, and no guidance on exclusions or prerequisites.

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