compare_driver_telemetry

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

With no annotations provided, the description carries the full burden. It describes the tool's behavior by specifying what gets compared and default behavior (fastest laps if lap numbers not provided), but doesn't cover important aspects like data availability constraints, rate limits, or authentication needs for a telemetry comparison 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 perfectly structured and front-loaded: purpose statement first, then Args with all parameters explained, Returns section, and a concrete Example. Every sentence earns its place with zero waste, making it easy for an agent to parse and understand.

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 complexity (7 parameters, comparison operation) and the presence of an output schema (TelemetryComparisonResponse), the description is nearly complete. It explains all parameters thoroughly and provides usage context. The main gap is lack of behavioral constraints disclosure, which would be helpful for a data-intensive comparison tool.

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?

With 0% schema description coverage, the description fully compensates by explaining all 7 parameters in detail: year constraints (2018+), gp format options, session codes, driver identifiers, and lap number behavior (fastest if None). The Args section provides complete semantic understanding beyond the bare schema.

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 purpose with specific verbs ('compare telemetry') and resources ('two drivers'), listing concrete aspects like 'racing lines, braking points, styles'. It distinguishes itself from siblings like get_lap_telemetry (single driver) or get_analysis (general analysis).

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 clear context for usage through the example, showing it's for comparing drivers in specific sessions. However, it doesn't explicitly state when NOT to use it or name alternatives among siblings, though the purpose implies differentiation from single-driver tools.

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