Race Control Messages

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is fully covered by structured data. The description adds modest value by naming the message categories and noting the race name is a partial match, but says nothing about ordering, volume, or freshness of the returned messages.

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 purpose sentence is front-loaded and the Args block is compact and scannable with no filler. It is slightly terse on defaults but wastes no words.

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?

An output schema exists, so return values needn't be described, and all four params are covered. The missing piece is sibling disambiguation against get_race_control_messages and the live variant, which is essential context for correct tool selection in this crowded namespace.

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 coverage is 0% with no enums, so the description must carry the param burden and largely does: it defines each of the 4 params and supplies concrete category values ('Flag', 'SafetyCar', 'Drs', 'Other', empty for all) that the bare schema lacks. It omits the non-obvious defaults (year=2026, session_type='Race'), which is the only shortfall.

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 verb and resource and enumerates the content returned ('flags, penalties, safety cars, investigations'), so the agent knows exactly what the tool produces. However, siblings get_race_control_messages and get_live_race_control appear to overlap almost entirely, and the description does nothing to distinguish this tool from them.

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?

No when-to-use, when-not-to-use, or alternative-selection guidance is given. With two near-identical siblings (get_race_control_messages, get_live_race_control) in the list, the absence of any routing hint is a real gap for selection.

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