get_live_lap_times

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

With no annotations, description carries full burden. It states the tool is live and requires no auth, but does not disclose other behavioral traits such as whether the data is updated in real-time, polling rates, or any limitations. Having an output schema helps but behavioral context is minimal.

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 concise sentences that front-load the core purpose and immediately follow with the key usage note. No redundant 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?

Given the tool has no parameters and an output schema, the description covers the basic need. However, it could mention that it’s tied to a live session or that results are from the current session, but missing that is acceptable for simplicity.

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?

Tool has 0 parameters with 100% schema coverage. Baseline is 4 per rubric. Description adds slight value by mentioning 'per driver' implying the result is per driver, but no parameter details are needed.

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?

Description clearly states it retrieves live last and best lap times per driver. Distinguishes from sibling tools like get_lap_times (historical) and get_live_sector_times (sector-specific) by specifying 'live' and 'per driver'.

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?

Specifies 'No auth required' as a usage condition, but does not provide explicit when-to-use or when-not-to-use guidance relative to siblings like get_live_sector_times or get_live_time_gaps. The purpose is implicit but not directive.

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