openf1_position

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

With no annotations, the description must carry the full burden of behavioral disclosure. It only states the return format and a vague 'position over time' without detailing whether data is real-time, historical, or scoped to a specific session. No mention of authentication, rate limits, or side effects. The tool appears read-only but this is not confirmed.

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 condensed into two sentences, the first stating purpose and the second showing the return structure. It is front-loaded and has no unnecessary words. However, it could be slightly more structured, e.g., by listing parameters separately.

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 4 parameters and no output schema, the description covers only the purpose and return format. It omits parameter explanations, usage context, and behavioral traits. This leaves significant gaps for a tool of moderate complexity, making it incomplete.

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 0% descriptor coverage, and the description does not explain any of the four parameters (position, meeting_key, session_key, driver_number). It only shows output fields. Without parameter semantics, the agent cannot correctly invoke the tool with proper filters. The description fails to compensate for the schema gap.

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 returns 'Driver track position over time — position changes throughout a session.' This conveys the specific resource and verb, and the return format distinguishes it from other openf1 tools like laps or intervals. However, it doesn't explicitly state whether it returns data for all drivers or a single driver, which slightly reduces clarity.

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 provides no guidance on when to use this tool versus alternatives, such as openf1_laps or openf1_intervals. There is no mention of prerequisites, when not to use it, or how it fits into a larger workflow. This leaves the agent without sufficient context for selection.

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