Get Driver Profile

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

No annotations are provided, so the description carries the full burden. It does disclose useful behavioral traits — the returned fields and the 160,000 km Easter egg trigger — but never states that this is a read-only operation, nor any auth/permission needs. It adds real context but does not fully cover the behavioral profile.

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?

Front-loaded and readable, but the trailing 'Returns JSON with: current_rank, total_distance_km...' duplicates content already conveyed by the output schema, so not every sentence earns its place.

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?

With an output schema present, the description need not (and largely need not have) re-listed return fields, yet it still conveys purpose and content adequately. The only meaningful gap is the absence of any routing guidance among the many sibling tools.

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 100% and the single car_id parameter is fully documented in the schema with its default-resolution logic. The description adds nothing about car_id, so the baseline of 3 applies.

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?

States a specific verb and resource ('Get driver gamification profile') and enumerates the exact content (rank, milestones, Easter eggs), so the agent knows what it retrieves. However, it never distinguishes itself from conceptually overlapping siblings like check_driving_achievements, check_daily_quest, or tesla_driving_score.

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 when-to-use, when-not-to-use, or alternative-tool guidance. With several gamification-adjacent siblings (check_driving_achievements, get_vehicle_persona_status, check_daily_quest), the agent is left to infer which one to call.

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