Claude skill

The skill teaches Claude to work with DuctTape.io: draw an architecture from code or a description, keep a diagram in step with the code, explain it and check it for gaps. Claude works on drafts only. Publishing and deleting stay with you in the app.

Set up in Claude Code

Unpack the archive into your skills folder. The skill then sits at ~/.claude/skills/ducttape and Claude uses it as soon as a diagram comes up.

Set up in the Claude app

Open the settings, go to the skills section and upload the archive as it is. Skills need code execution there.

Connect your account

With a connection Claude creates diagrams right in your account and gives you the link to the editor. Create an access token in the settings and enter it:

Without a connection Claude writes a JSON file. You open it in the dashboard with "Import from JSON".

What the skill contains

Instructions with modelling rules and typical architectures, the block catalog and a small script that checks a diagram file and arranges the blocks. The script needs Node.js 18 or later and no further packages.
