Brouter

Generate GPX bike routes via brouter.de. Use when the user wants a bike route as a GPX file between two places, optionally specifying a routing profile. https://github.com/si-gr/brouter-skill

This OpenClaw skill queries the brouter.de webservice and generate GPX bike tracks.

Usage

Natural language prompts

You can trigger this skill with prompts like:

• "Create a GPX for a bike route from [origin] to [destination] (profile: [profile])."
• "Give me a quiet route from Prenzlauer Berg to Kreuzberg as a GPX."
• "I need a fast bike route from Berlin Hauptbahnhof to Alexanderplatz as a GPX file."

Parameters to extract

When using this skill, identify:

• origin: Free-text description of the starting location.
• destination: Free-text description of the end location.
• profile : One of the supported brouter profiles below.

Parse all location data to coordinates before using index.js. Never use free-text descriptions of locations directly as input for index.js. Use coordinates as origin and destination input for index.js.

Heuristics for choosing a profile

• Prefer trekking when the user does not specify a preference.
• Prefer trekking-fast when the user asks for a fast or time-efficient route.
• Prefer trekking-safe or shortbike when the user asks for a quiet, safe, or kid-friendly route.
• Prefer fastbike when the user mentions road bike, speed, or being an experienced cyclist.
• Prefer moped only if the user explicitly indicates using a moped or similar vehicle.

Agent implementation: coordinates

When this skill is triggered, the agent should first derive coordinates from the user's origin and destination, then use index.js to make structured request to brouter.de

1. Derive coordinates from user input

1. Extract plain-text locations:
   • origin — starting point
   • destination — end point
2. If the user already supplies coordinates (e.g. 13.4244,52.5388), use them directly.
3. Otherwise, geocode the locations into lon,lat pairs
4. Ensure the final values are strings in the form:
   • "<lon>,<lat>" (longitude first, then latitude)

2. Use index.js

Once you have start and end as lon,lat strings and a chosen profile, use the index.js as follows:

cd workspace/skills/brouter && node -e "(async () => { const run = require('./index'); const result = await run({ start: '<lon>,<lat>', end: '<lon>,<lat>', profile: '<profile>' }); console.log(result); })().catch(err => console.error(err));"

Reply to the user with the response file found in routes/ folder.

See the earlier "Derive coordinates from user input" section for recommended heuristics when turning user prompts into coordinates.
