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.

Neither the package manifest nor the repository tree declares a licence.

The maintainer states it is unofficial, not endorsed by SAP, and that it uses authenticated Hub web and catalogue endpoints and browser session cookies in ways SAP's terms of service, SAP account terms or an organisation's own policies may restrict. The same README asks the reader not to use it for production, broad distribution or shared access without explicit approval, and says that installing it grants no permission to automate SAP services.

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.

Neither the package manifest nor the repository tree declares a licence.

It needs an S-user with SAP Support Portal access, so there is nothing to search without a support contract behind the login. The maintainer states it uses private SAP APIs behind authentication, asks the reader to check whether that use breaches SAP's terms of service, and disclaims both liability and any guarantee that it keeps working. MFA is handled only by typing the code into a visible browser, so a headless deployment cannot complete a login that demands one.

What it returns is planning material, not a commitment, and the monorepo labels the server's role "future/planned features (planning only)". The maintainer also states it is unofficial, not endorsed by SAP, and that it uses authenticated Road Map Explorer web endpoints and browser session cookies in ways SAP's terms of service or an organisation's policies may restrict, with production, broad distribution and shared access called out as needing explicit approval. An account that requires MFA has to be bootstrapped once through a visible browser.

No license Neither the package manifest nor the repository tree declares a licence.

Functional boundary The repository publishes no licence, so reusing the files needs the author's permission. Nothing here says what each file contains, and the two posts they were published for are in Japanese.
