Optimize stop order

optimize_route
Read-onlyIdempotent

Find the most efficient order for visiting multiple stops, returning an optimized itinerary with total distance and time. Choose roundtrip or one-way.

Instructions

Finds the best order to visit a set of stops (traveling-salesman optimization) and returns the optimized itinerary with total distance and time. With roundtrip (default) the tour returns to the first stop; without it the first stop is the start and the last stop the end.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
stopsYes
profileYesTravel mode: on foot, by car or by bicycle
languageNoLanguage for resolved place labels, default "en"
roundtripNoReturn to the first stop at the end, default true

TDQS

A4.1/5.0
Behavior4/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds the roundtrip semantics (default true returns to first stop, false treats first as start and last as end), which is not covered by annotations. It also mentions the return includes total distance and time, adding useful behavioral context beyond the safety hints.

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?

Two sentences with zero waste. The first sentence front-loads the core purpose and output, the second clarifies the roundtrip option. No redundant filler or repetition of schema details.

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

Completeness5/5

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

The description is complete for a read-only TSP tool. It covers the essential behavior (optimization, roundtrip), the return (itinerary, distance, time), and the output schema exists to detail the exact structure. Annotations cover safety and idempotency. Nothing critical is missing for an agent to call it correctly.

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 description coverage is 75% (actually all parameters have descriptions, so coverage might be higher, but given the signal). The description does not add much beyond the schema: it explains roundtrip behavior, but the schema already says 'Return to the first stop at the end, default true'. The description's explanation is slightly more detailed but adds marginal value. No new parameter information is introduced.

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 a specific verb ('Finds the best order') and resource ('set of stops') with the traveling-salesman optimization context. It distinguishes itself from siblings like route or route_matrix by focusing on optimization rather than simple pathfinding, making its purpose unmistakable.

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

Usage Guidelines3/5

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

The description explains the roundtrip behavior but does not explicitly state when to use this tool versus alternatives. It does not mention that for a simple A-to-B route one would use 'route', or that for multiple routes 'route_matrix' is appropriate. Usage context is implied by the optimization focus but not spelled out.

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