What problem does it solve? HTML artifacts produced by workbench producer skills all share default styling, and restyling each artifact by hand is repetitive and inconsistent. This Skill lets you author a reusable design system of CSS variable overrides, typography, components, and images that producers apply automatically. ## Core Features & Use Cases - Design system authoring: Create a named design system at project scope (.workbench/design-systems/<name>/) or user scope (~/.claude/workbench/design-systems/<name>/) with a required manifest.md and colors.css. - Optional extensions: Add typography.css font overrides, self-contained components/*.html snippets, and images/ that producers base64-inline into artifacts. - Per-template variable inventory: A table maps which CSS variables each producer template (brainstorming, writing-spec, writing-plans, systematic-debugging, research) actually consults, so overrides target real variables. - Use Case: A team wants all generated specs and plans to match their brand. They copy the starter palette, adjust accent and ink colors, wire the name into .workbench/config.md, and every subsequent producer render uses the new theme. ## Quick Start Ask the assistant to create a new project-scoped design system named brand-2026 using the starter palette and set it as the active design system.
