One line
First glance: that era of serious Chinese productivity systems.
Second glance: no real OS interface to recognize.Sickle is a fictional original visual language for efficiency systems.
It supports personal-system demos, product concepts, article figures and workflow diagrams — without cloning any commercial OS.
What it fixes
Personal-system and AI-workflow content often looks like:
- PPT screenshots
- cartoon illustrations
- “serious tool” intent that accidentally mimics a brand
Sickle provides repeatable DNA: restrained skeuomorphism, precise grids, crimson cut-lines, Chinese productivity craft.
Boundaries
Never recreate Smartisan / hammer-brand logos, icons, screenshots or identifiable layouts.
Do invent original components under the Sickle name.
Relation to Xiao-K
Sickle = system / product visual language
Xiao-K = narrative character IPStatus
