Brandkit

This generates a complete design token system from a brand brief: primitive color ramps in OKLCH, semantic mappings for light and dark modes, type scales, spacing, and motion, all exported as DTCG JSON and a single theme.css. It runs WCAG contrast validation automatically and enforces the three-tier token architecture (primitive, semantic, component) so you never hardcode colors again. Use it when you need a themeable foundation before building screens, or when you're tired of inconsistent palettes and want one source of truth. The output is verifiable (it includes Python scripts for contrast and reference checking), though the brand feel still needs a human eye. It's opinionated about structure but that's the point.

Skill: Brand Kit

Requirements

This skill needs the full UX/UI Agent Skills kit: the gates, the references and the design-system library. Install it with npx ux-ui-agent-skills@3.1.0 init or as the Claude Code plugin. npx skills@1.7.6 add copies the skill folder and nothing else. Installed that way, this skill runs in guidance-only mode: no gate runs, so it gives no verdict.

Step 0: is the kit here? Check once: ls ${CLAUDE_SKILL_DIR}/../../../tokens >/dev/null 2>&1 && echo KIT_OK || echo KIT_MISSING On KIT_MISSING, open your reply with: "Guidance-only mode: the UX/UI Agent Skills kit is not installed here, so no gate ran and nothing below is measured." Then work from this file and general practice, under three rules. Do not guess or cite the contents of a kit file you could not open. State no measured number (no contrast ratio, no N/N, no "passes WCAG"): write "not verified" where one would go. End with a line Skipped (kit not installed): that names every gate script this file tells you to run, then the install command above.
