Trystan-SA/claude-design-system-prompt ? reverse-engineered prompt

Build me an open source prompt library that turns a model into a really strong design collaborator, not a generic SaaS mockup generator.

I want the main README and docs to explain a clear design philosophy, with a system prompt that pushes for accessibility, strong visual hierarchy, purposeful spacing and color, real interaction states, and an anti template, anti AI slop approach. Include a set of reusable skill prompts for things like discovery questions, choosing a visual direction, wireframes, prototypes, design system extraction, component extraction, accessibility review, hierarchy and rhythm review, interaction state review, and a final polish pass.

Make it easy to use in different LLM environments, with one version for Claude style workflows and one for Codex style workflows, plus a clean folder structure for the prompt files and skills. Keep the writing crisp and practical, and make the project feel polished and useful for real design work. If anything is unclear, check current docs online first.
