formulae_driver_standings

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

Annotations already mark this as read-only, open-world, and idempotent. The description adds behavioral details about the response format—a top-level array with specific fields—and notes no authentication is required.

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 compact but informative, covering purpose, return format, example, and auth. The inclusion of the full return field list is somewhat lengthy but provides necessary detail without an output schema.

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?

For a simple, one-parameter read-only tool, the description sufficiently covers usage and output shape. Lacks any mention of ordering or filtering, but the schema and annotations provide a clear picture.

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 single parameter championshipId is fully described in the schema as a championship UUID. The description supplements this with a concrete example value and clarifies that the standings are for that season.

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?

Clearly states it returns drivers' championship standings for one season. The name and description together distinguish it from team standings and other motorsport standings tools.

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?

Provides context on when to use (for driver standings per season) and includes an example of the required championshipId. Does not explicitly mention alternatives, but the description is clear enough that sibling tools like formulae_team_standings would be chosen for team standings.

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