Install the skill in Claude CoworkCopy link

The skill is a package that teaches an AI assistant how to drive Routing24: the tools the page exposes, the constraint vocabulary, and the working procedure from addresses to a saved plan.

Get the skillCopy link

Three places, same package:

  • In the app: the AI SKILL button in the header downloads it directly.
  • From the site: routing24.com/routing24.skill, and the identical archive as routing24.com/routing24.zip for uploaders that insist on a .zip extension.
  • From GitHub: github.com/routing24/skill holds the same content as browsable source, with the packaged file on its latest release. SKILL.md can be read there before installing, and its changes between releases are visible.

Inside is SKILL.md, the instructions themselves, plus a references/ folder: the full API contract, a machine-readable JSON schema of every constraint, and ready-to-run call examples. It is generated from Routing24's own types on every release.

Install it in Claude CoworkCopy link

Claude Cowork is Anthropic's agent for multi-step work across your files and tools, on the Claude desktop app and at claude.ai. It can both handle your files and work in your browser, which is what this skill needs.

  1. Download routing24.zip (or rename the downloaded routing24.skill to .zip, it is the same archive).
  2. In Cowork, click Customize in the left sidebar.
  3. Open the Skills tab, click the + button, then + Create skill.
  4. Choose Upload a skill and select the archive.

Claude lists it as Routing24 route optimizer. It needs no API key, no account connection, and no Routing24 login.

What Cowork needs on your side

Cowork runs on paid Claude plans, and skills require code execution to be enabled for your account. On Enterprise plans an owner has to switch on Skills in the organization settings first. To let it work on the Routing24 page, Cowork also needs browser access, which is the Claude desktop app on macOS or Windows with browser actions available. Anthropic's own Use skills in Claude is the current reference for both.

Other assistantsCopy link

The package is a standard Agent Skill, not a Claude-only format.

  • OpenAI Codex reads skills from disk rather than from an upload dialog. Unpack the archive into an .agents/skills folder, for example ~/.agents/skills/routing24-optimizer/, so that SKILL.md sits inside it.
  • Any WebMCP-capable assistant can drive Routing24 with or without the skill, because the tools are published by the page itself, see WebMCP: Routing24 as an AI tool. The skill supplies the calling convention, so you do not have to describe it each session.

First runCopy link

Open routing24.com/app in your browser, then ask the assistant something small and verifiable:

Open Routing24 and check that the routing24 tools are available on the
page. Then plan a route from our depot at 14 Chaussee de Mons, Brussels
to these three addresses, one van, and show me the result.

On a successful run, the assistant confirms the tools, geocodes the four addresses and reports any it could not place, starts the optimization, polls it, then tells you the number of routes, total distance and duration, and gives you a link to the plan. The routes appear on the map in your tab while it works.

If it reports that the tools are missing, the page had not finished loading, or the assistant is looking at the wrong tab. Reload the Routing24 tab and ask again.

Saved plans and sign-in

If you are not signed in, a saved plan lives in that browser on that computer only, so its link will not open anywhere else. Sign in before you save when the link has to reach a colleague or a driver. Everything else works anonymously, and the assistant is told never to ask you to log in.

Keeping it currentCopy link

The skill carries a version, and Routing24 changes between releases. To update, download it again and re-upload it, replacing the old one. There is no auto-update.

The contract lives at routing24.com/llms.txt, regenerated on every release. An assistant can fetch it when a call fails on a field its copy does not know about.
