Live Lap Times

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

Annotations already declare readOnly, idempotent, openWorld and non-destructive behavior, so the safety profile is covered. The description adds two genuinely useful facts outside the structured fields: the payload contains last AND best lap time per driver, and no authentication is required. It says nothing, however, about update cadence or which session it binds to, so it is adequate rather than rich.

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 sentences, zero filler, with the payload content front-loaded before the auth note. Every clause carries information.

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 shape need not be explained, and there are no parameters to cover. The only meaningful gap is the absence of any statement about live context (which session, refresh behavior) in a toolset crowded with live_* siblings that an agent must choose among.

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, and the schema description coverage is 100% with no fields to document. Baseline of 4 applies: there is no parameter ambiguity the description could resolve.

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 names a specific resource (lap times) with a scoping qualifier (live, last + best) and the granularity (per driver), which separates it from the historical sibling get_lap_times. It does not explicitly name or contrast with that sibling, so the differentiation is implied by the word 'Live' rather than stated.

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 call this versus the many adjacent live siblings (get_live_sector_times, get_live_time_gaps, get_lap_times). No prerequisites, no session/context conditions are given; the agent must infer usage 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.
