The Claude Design System prompt is a reverse-engineered system prompt and skill library that transforms a large language model (LLM) into an opinionated, accessibility-aware design collaborator. It is open source and MIT licensed, compatible with any LLM that supports system prompts, and addresses the limitations of typical design assistant prompts by avoiding generic outputs.

Claude Design is a new product from Anthropic Labs that allows users to collaborate with the AI to create visual work such as designs, prototypes, and slides. It is powered by the Claude Opus 4.7 vision model and is available in research preview for Claude Pro, Max, Team, and Enterprise subscribers, with a gradual rollout to users.
