Driver Tyre Detail

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds that data is sourced via FastF1 and that output covers compound, laps, and degradation, but reveals nothing about error cases (e.g., missing driver/session data), which matters most for an openWorldHint 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?

A single, front-loaded sentence with no wasted words. It is efficient, though brevity here trades off against the missing parameter and usage detail the schema does not provide.

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?

An output schema exists, so return values need not be explained. However, for a 3-required-parameter tool with 0% schema coverage and many competing tyre siblings, the description omits both parameter format guidance and sibling differentiation, leaving real gaps an agent must guess at.

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 0%, so the description carries the full burden of explaining the three required parameters. It only hints at 'specific driver' and says nothing about the expected format of year or gp (round/name/abbreviation), so the agent has no clarity on how to supply two of three required inputs.

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+resource ('Get detailed tyre stint data for a specific driver') and enumerates the payload (compound, laps, degradation). It clearly conveys what it does, but does not distinguish itself from close siblings like get_tyre_strategy, get_stint_analysis, or compare_tire_age_performance.

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 guidance on when to use this tool versus alternatives, despite a crowded field of tyre/stint siblings. No prerequisites or exclusions are stated, leaving the agent to infer scope from the name alone.

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