uxskill

uxskill is a Python-based design system compiler for AI coding tools like Claude Code, Cursor, and Windsurf. It takes a design brief and generates a deterministic design language across seven axes (warmth, contrast, density, geometry, formality, motion, type), anchoring output to your brand rather than producing generic templates. The tool runs offline with no LLM calls, lints against 152 anti-pattern rules, verifies mobile rendering at true viewport sizes, and works across 17 AI coding environments.

Designed for developers and design engineers who want AI-generated interfaces to feel distinctive. It compiles 160 brand specifications, 84 styles, 176 palettes, and 70 type pairings into queryable JSON manifests. Free and MIT-licensed, it installs via pip and includes 25 slash commands, 5 sub-agents, and 18 MCP tools for integration into your workflow.
