+]Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint false, so the safety profile is covered. The description adds no extra behavioral details (e.g., pagination, response format) beyond the core multimodal comparison, which is acceptable given the annotations.
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 sentences with zero redundancy. The primary purpose is front-loaded, and the default-tool note is efficient and actionable.
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?
With an output schema present, return values are covered. The description plus schema adequately define the tool's behavior and inputs for a read-only multimodal planner. Could mention that pickup/destination should be resolved places, but that is already implied by the placeId schema description.
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 reported as 100% (though name/address lack descriptions in the schema, the metric suggests coverage). The description does not elaborate on parameters, but the schema provides adequate meaning, so the baseline of 3 applies.
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 clearly states the tool compares ride-hailing and trotro options together, which is a specific verb+resource. It also declares itself as the default for multimodal trip planning, distinguishing it from single-mode siblings like compare_rides and plan_trotro_route.
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?
The description explicitly frames this as the default for multimodal planning, implying use when both modes are needed. However, it does not explicitly state when to use the single-mode alternatives or provide exclusions, so it stops short of full guidance.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
