get_live_speed_comparison

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

Without annotations, the description bears full burden. It adds 'No auth required' but leaves out other behavioral traits like read-only nature, data freshness, caching, or rate limits. An agent might need more info for correct invocation.

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 front-load the purpose and critical prerequisite. No wasted words; every sentence adds value.

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 low complexity (no parameters) and an output schema existing, the description covers essential purpose and auth requirement. It could mention the output is per driver or the standard meaning of measurement points, but overall it is mostly complete.

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?

There are no parameters, and schema coverage is 100% (trivially). The description does not need to add parameter details, so a baseline score of 4 is appropriate.

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 best speed at specific measurement points (I1, I2, FL, ST) for every driver. The verb 'get' is implied, and the resource is well-defined, distinguishing it from siblings like get_live_sector_times or get_live_speed_trap.

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 explicitly notes 'No auth required,' which is a helpful prerequisite. It does not provide when-to-use vs alternatives, but the purpose is clear enough for an agent to infer usage context. A slight improvement would be to mention it complements other live tools.

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