Tyre Age vs Pace

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 covered. The description adds nothing beyond that — no note on data range, whether the comparison is per-stint or per-lap, or how the fresh/used split is determined.

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 or redundancy. It is efficient, though its brevity is partly the cause of the gaps elsewhere rather than pure concision virtue.

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 need not be explained, but for a three-parameter analytical tool with zero schema descriptions the definition omits required-parameter meaning and any selection guidance. An agent has the schema shape but not enough context to know when this is the right tool.

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% across three required parameters (year, gp, driver), and the description never mentions any of them. Unlike the annotation-covered dimensions, the schema provides no compensating detail here, so the description fully fails its parameter-documentation duty.

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 (compare) and resource (lap times on fresh vs used tires), which is enough for an agent to recognize it as a tyre-degradation pace comparison. It does not differentiate itself from near-neighbors like compare_tire_compounds, get_tyre_strategy, or analyze_long_run_pace, which an agent could easily confuse it with.

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 guidance, no prerequisites, and no mention of alternatives such as compare_tire_compounds or get_driver_tyre_detail. The agent is left to infer the trigger condition from the name alone.

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