openf1_get_intervals

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

With no annotations provided, the description bears full responsibility for behavioral disclosure. It mentions the data represents gaps relative to the leader during a session, but does not discuss data freshness, pagination, rate limits, or handling of sessions with no interval data. This is insufficient for a data retrieval tool.

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 conveys the tool's purpose efficiently. There is no extraneous information, and every word contributes to understanding.

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's simplicity (two parameters, one required, no output schema), the description adequately explains what the tool does. However, it lacks details about the output format or the structure of interval data, which would be beneficial for completeness.

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?

Schema description coverage is 100% as both parameters ('session_key' and 'driver_number') have descriptions. The tool description adds the context 'during a session', but this is already implied by the parameter descriptions. The baseline score of 3 is appropriate as the description adds minimal value beyond the schema.

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 the tool retrieves interval data showing the gap between drivers and the leader during a session. It uses a specific verb ('Get') and resource ('interval data'), and distinguishes itself from sibling tools like openf1_get_car_data or openf1_get_laps by focusing on intervals.

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?

No explicit usage guidelines are provided. The description implies usage for retrieving interval data but does not state when to use this tool versus alternatives, nor does it mention any prerequisites or exclusions. The context is clear but lacks depth.

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