A structured design vocabulary that gives AI something precise to execute from — so your work looks like yours, not like everyone else's.
Without a design language, AI defaults to the statistical mean of its training data. The same muted gradients. The same card grids. The same headlines about building futures.
Design Substrate is a skill for Claude Code, Codex, and Gemini CLI. It discovers your taste through conversation, sketches real pages immediately, and systematizes what works into portable tokens.
The output is a git repo that IS your design system — browsable HTML, zero dependencies.
One skill file. Your substrate travels with your project — consistent aesthetic across every tool.
