Get Positions

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

No annotations are provided, so the description carries the full behavioral burden. It discloses only that data represents 'changes' across a session; it says nothing about pagination, ordering, data volume, or auth/rate-limit behavior for what is likely a large time-series payload. This is thin for a tool with zero annotation coverage.

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?

A single front-loaded sentence with no filler, so nothing is wasted. It is arguably under-specified rather than concise, but structurally it is clean and immediately readable.

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?

With 8 optional parameters, no annotations, and no guidance on parameter combinations (e.g., that exact position conflicts with position_min/max, or how date ranges interact), the description is too sparse. The existence of an output schema excuses it from explaining return values, but the invocation guidance is still 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?

Schema description coverage is only 50%: position, meeting_key, session_key, and driver_number are documented in the schema, but date_to, date_from, position_max, and position_min are bare. The description adds no parameter meaning at all, so it fails to compensate for the undocumented half, including the position_min/max range semantics.

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 gives a specific verb ('fetch') and resource ('driver position changes throughout an F1 session'), which is more precise than a tautology and hints at time-series change data rather than a static grid. It does not, however, explicitly distinguish itself from near neighbors like get_starting_grid or get_session_results, so sibling differentiation is left to inference.

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?

There is no when-to-use guidance, no when-not-to-use, and no mention of alternatives among the many position-related siblings. The phrase 'throughout an F1 session' is the only contextual hint, leaving an agent to guess whether this or get_starting_grid is appropriate.

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