Penalties

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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and openWorld, so the safety profile is fully covered by structured data. The description adds nothing beyond them — no note on whether qualifying/sprint penalties are included, whether data is only available for recent seasons, or how a missing race is handled.

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; the resource and session scope come first. It is efficient, though so terse that it leaves obvious gaps unaddressed rather than being genuinely complete.

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?

The presence of an output schema means return values need not be described, but with 0% parameter coverage and no usage guidance, the agent is missing the gp identifier format and the boundary against race-control siblings. For a two-required-parameter lookup tool this is thin.

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 0%: 'gp' and 'year' have no titles beyond bare names, and the description supplies no parameter detail at all. In particular the gp string format (full race name, country, or code) is undefined in both places, which is a real risk for correct invocation.

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 names a specific verb and resource ('Get all penalties') and scopes it to the race session, so the agent knows what data comes back. It does not, however, distinguish itself from close siblings like get_race_control or get_race_control_messages, which an agent could reasonably confuse with penalty data.

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 statement of when to use this tool versus the many race-control and results siblings, nor any prerequisites (e.g., that year and gp must identify a completed race). Usage is left entirely to inference from the name.

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