muriel

muriel is a Claude Code skill that produces visual artifacts across sixteen channels — fourteen output + two cross-channel references — enforcing an 8:1 contrast floor and brand-token discipline at render time. Design tokens import from `design.md` and export to W3C DTCG; a vision-model critique agent audits the output; the floor never bends.

A single skill file (`SKILL.md`) teaches the agent to generate every visual artifact a researcher-designer-engineer ships — from text source files that diff in git and regenerate from data. The constraint discipline (8:1 contrast, OLED palette, one font treatment, generated > drawn, reproducible > one-off) stays live at render time: brand tokens are parsed, contrast is audited, dimensions are enforced — not as lint after the fact, but as part of the act of making.
