Session result

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is covered. The description adds meaningful behavioral context beyond annotations: the DNF/DNS/DSQ flags and the special array behavior for duration and gap_to_leader in qualifying.

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 tight sentences, front-loaded with the core result definition and followed by a useful edge case. Every sentence earns its place with no redundant restatement of the tool name.

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 seven optional parameters with full schema coverage and no output schema, the description is nearly complete: it names the returned fields and explains the qualifying array nuance. A minor gap is the absence of any note about pagination or the limit-summary behavior, though the schema covers the limit parameter.

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%, so all seven parameters are fully documented in the schema. The description adds no parameter-specific semantics beyond what the schema already provides, which is the expected baseline when schema does the heavy lifting.

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?

States a specific resource and scope: 'Final standings of a session' with enumerated fields (position, laps, duration, gap, DNF/DNS/DSQ). This distinguishes it from live-position tools like get_position, but it does not explicitly name or contrast with any sibling.

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?

Usage is implied by 'Final standings of a session' and the qualifying-array note, but there is no explicit when-to-use/when-not guidance or reference to alternatives such as get_position or get_race_summary.

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