get_live_sector_times

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

No annotations are provided, so the description carries the full burden. It correctly states 'No auth required,' which is a key behavioral trait. However, it does not disclose other behaviors such as whether data is real-time or cached, any rate limits, or the exact return structure (though output schema may cover that). This is minimal but adequate.

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 a single sentence that front-loads the main purpose ('Live sector times + speed trap for one driver') and then adds the key constraint ('TLA or car number') and access requirement ('No auth required'). No wasted words.

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 that an output schema exists, the description does not need to detail return values. It fully covers what the tool does (returns sector times and speed trap for one driver) and how to specify the driver. This is sufficient for an agent to select and invoke the tool correctly.

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 input schema has only one parameter ('driver') with no description (0% coverage). The description adds critical semantic information by specifying that the driver can be a TLA (three-letter abbreviation) or car number. This goes beyond the schema and is essential for correct invocation.

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 it returns live sector times and speed trap for a single driver. It uses a specific resource ('sector times + speed trap') and specifies it's for one driver, distinguishing it from sibling tools like get_live_best_sectors (which likely aggregates best sectors across drivers) and get_live_speed_trap (which might return all drivers' speed traps).

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 indicates the tool is for a single driver and requires a driver identifier (TLA or car number). It implies usage when you need both sector times and speed trap for one driver. However, it does not explicitly exclude cases where you might want only sector times (use get_live_best_sectors?) or only speed trap (use get_live_speed_trap?), leaving some ambiguity.

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