get_longest_drives_by_distance

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It only states the high-level action and grouping ('for each car'), but fails to explain key behaviors such as whether it returns a single drive per car or multiple, how 'longest' is determined (e.g., sorting, limit), or whether it is read-only. Minimal extra behavioral context is offered.

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 concise sentence that front-loads the primary action and object. Every word contributes to the meaning, with no redundancy or filler.

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 (no parameters) and the presence of an output schema, the description provides sufficient high-level context. It does not need to explain return values since the schema does that. The only minor ambiguity is whether 'longest drives' is singular or plural per car, but this is likely resolved by the output schema.

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 tool has zero parameters, so the description cannot add parameter semantics. The schema is empty with 100% coverage (vacuously). Per the rubric, a baseline of 4 is appropriate when there are no parameters to explain.

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 with a specific verb ('Get') and resource ('longest drives by distance for each car'). It is distinct from sibling tools like get_drive_summary_per_day or get_total_distance_and_efficiency, though it does not explicitly name alternatives. The core purpose is unambiguous.

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 the many sibling get_* tools. It does not mention any context, prerequisites, or alternatives. The usage is only implied by the name and description, not explicitly stated.

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