Install
Installing genjutsu on Claude Code and on claude.ai, checking that it took, keeping it current, and removing it.
All documentation
Two doors, same skill. Pick the surface you actually work in.
Claude Code
Type both commands inside a Claude Code session. The first registers the marketplace, the second installs the plugin from it.
/plugin marketplace add AThevon/genjutsu
/plugin install genjutsu
Once installed, two slash commands are available:
/genjutsu:cast
/genjutsu:paint
You can pass your request on the same line, which saves a round trip:
/genjutsu:cast make the pricing cards feel physical on hover
claude.ai, web and apps
Download the bundle and upload it as a skill.
- Download genjutsu.zip. That link always resolves to the newest release, so it never goes stale.
- In claude.ai, open Settings, then Customize, then Skills.
- Upload the zip and enable it.
- In any chat, write
/genjutsu, or simply describe what you want built.
The zip is self-contained: the two skills and all fifteen modules in one file, laid out so the modules resolve from inside the bundle.
Requirement: skills on claude.ai need the code execution feature, which is available on the Pro, Max, Team and Enterprise plans.
Checking that it took
In Claude Code, /plugin lists what is installed. Or just start typing
/genjutsu and see whether both commands are offered.
On claude.ai, the skill appears in the Skills list with a toggle. If it is listed but never seems to engage, confirm the toggle is on and that your plan includes code execution.
A working install announces itself: cast opens by scanning your stack and
naming what it found, before it proposes anything.
Staying current
Claude Code updates through the plugin system, same as any other plugin.
claude.ai has no auto-update for uploaded skills, so download the zip again
and re-upload it. Because the download URL points at releases/latest, you
never have to look up a version number. The footer of this site shows the
release the site last saw, which is a quick way to tell whether you are behind.
Removing it
In Claude Code:
/plugin uninstall genjutsu
On claude.ai, delete the skill from the Skills list.
Nothing to clean up in your project either way. genjutsu leaves behind the code
it wrote and, if you ran paint, a MASTER.md design system. Both are yours,
both are plain files, and neither imports anything from genjutsu.
