Reverse-engineer a project's real, shipped design language into a reusable design skill, so any agent can build or restyle pages that match it. Use when the user says 'create a design skill from this project', 'make a design skill from the current project', 'extract the design system', 'capture this app's design as a skill', 'codify our design language', or 'reverse-engineer the design system into a SKILL.md'.
