Route

route
Read-onlyIdempotent

Traffic-aware routing / directions: calculate the best route between two points and return distance plus travel time computed with live traffic. Reports traffic delay so you get realistic ETAs, not free-flow estimates. Supports car, truck, pedestrian, and bicycle travel modes. Example: route({ from_lat: 40.748, from_lon: -73.985, to_lat: 40.689, to_lon: -74.044 })

TDQS

A4.2/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true and idempotentHint=true. The description adds that it uses live traffic and reports traffic delay, providing behavioral context beyond annotations. No contradictions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is three sentences plus an example, front-loading key information (traffic-aware, returns distance/time). No redundant words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity, schema covers all parameters, and annotations provide safety profile. Description explains return values (distance, travel time, traffic delay) sufficiently. No output schema needed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema descriptions cover all 6 parameters (100% coverage). Description adds an example and mentions travel modes, but does not significantly enhance parameter meaning beyond the schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it provides traffic-aware routing/directions, calculates best route, returns distance and travel time with live traffic. It distinguishes from sibling tools like geocode (address to coordinates) and search_poi (POI search) by focusing on route calculation between two points.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description specifies when to use (for live traffic ETAs, delays) and mentions supported travel modes. However, it does not explicitly exclude alternatives among siblings, but since no other routing sibling exists, this is adequate.

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