Everything in the atlas

Any run nobody is watching: the drawing tools work only while the draw.io canvas at `http://localhost:3000/` is open and connected, so there is no diagram to produce on a build agent or a server. Nothing checks the result either, because the maintainer keeps a diagram linter on the [roadmap](https://github.com/etosin/arc-draw#-roadmap) rather than in the release. The maintainer marks the status early at v0.x, installs it from source, and records testing with Claude Code alone.

The exported file list is hard-coded, so a dev space whose setup lives in files the readme does not name is not carried across; the roadmap lists making the list flexible as open work. Nothing from the BAS profile is in the zip, so a developer who wants the colour scheme, the keymaps or the installed extensions uses the BAS profile export on its own.

The README tells you to fork before cloning, because Claude rewrites `references/` and `SKILL.md` in place as you use it, so a clone shared between people changes under all of them. Installing means `git` and `ln` on macOS or Linux and a symlink into `~/.claude/skills`. Fine positioning stays manual: the coordinates Claude writes can be rough apart from the centre coordinates of elements joined by a straight arrow and the containment relationships.

A diagram of anything other than an SAP, BTP or on-premise landscape: the skill is tuned to the Horizon style and its 71 templates. It drafts rather than finishes, and its README budgets 15 to 30 minutes of edits in draw.io per diagram. Without Python the validator does not run.
