Live Tyres

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint, so the safety profile is fully covered. The description adds one genuinely useful behavioral fact not in annotations – 'No auth required' – but says nothing about update frequency, freshness, or live-session preconditions.

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?

Two short, front-loaded sentences with no filler; the data fields are stated first and the auth note second. It is appropriately sized, though the second sentence is a small operational aside rather than core purpose.

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 needn't explain return values, and with 0 params there is little to document. Still, it omits sibling differentiation against several live/tyre tools, which is the main remaining gap for an agent choosing among them.

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 takes zero parameters, so there is no parameter semantics burden; the baseline for a 0-param tool is 4. Nothing in the schema needs compensating for.

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 (returns/live) and resource (tyre compound, age in laps, stint number per driver), so the agent knows exactly what data comes back. However, it does not distinguish itself from closely related siblings like get_live_stint_history, get_driver_tyre_detail, or get_tyre_strategy, leaving overlap unresolved.

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 choose this over get_live_stint_history or get_tyre_strategy, nor any stated preconditions or exclusions. The agent must infer the usage scenario 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.
