Plot Gear Shift Map

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so safety and idempotency are covered. The description contributes only the single-driver scoping constraint and says nothing about rendering behavior, cost, or rate limits, which is thin but acceptable given the annotation coverage.

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, which is efficient. However, it is arguably under-specified rather than genuinely concise, leaving no room for the parameter detail this tool needs.

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 described, but the tool takes four undocumented parameters at 0% schema coverage, including a non-obvious session code default. For a plotting tool with this many inputs, the description is materially incomplete.

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 four parameters, and the description adds no meaning for year, gp, driver, or the session default of 'Q'. With no enums and no parameter notes, an agent must guess what values gp and session accept.

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 ('Generates') and resource ('Gear Shift chart') with a scope limiter ('for a single driver'). It is reasonably distinguishable from the plot_* siblings, but it never names or contrasts with them, so full sibling differentiation is missing.

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 guidance on when to use this chart versus alternatives like plot_telemetry_comparison or plot_driver_telemetry_comparison, and no prerequisites are stated. 'For a single driver' hints at scope but is not framed as a selection condition.

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