What it does
The skill starts by checking that the full kit is installed, not only the skill folders that `npx skills add` copies. If files are missing it says so, points you to `npx ux-ui-agent-skills init` or the plugin install, and stops. Then it infers a brief covering industry, audience, one mood adjective and motion depth, and picks an anchoring archetype.
From there it generates an 11-shade brand color ramp in OKLCH plus a neutral ramp, maps them to semantic roles for actions, text, surfaces, borders and feedback, and designs dark overrides rather than inverting colors. It adds a Major Third type scale, a 4px spacing scale, radius tiers, elevation and motion timings, then emits DTCG token JSON and a single `theme.css` with `[data-theme="dark"]` overrides. Three Python scripts verify the result: token validity, contrast in both themes and theme variable references.
When your agent uses it
- Starting a new product that needs a brand palette and type system from scratch
- Creating a themeable token kit with light and dark modes
- Replacing scattered hardcoded colors with one shared theme file
Example prompts
- “Create a brand design system for a meditation app with calm, warm tones.”
- “Generate DTCG tokens and a theme.css for our logistics dashboard, light and dark.”
- “Build a color and type foundation for a fintech startup and verify WCAG contrast.”
Requirements
- The ux-ui-agent-skills kit installed, not only the skill folders
- Python 3 for the validation scripts

What it can do on your machine
Read from SKILL.md and the folder at commit 14f8d44. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python3npxnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx and npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Brand Kit Design Tokens loads about 809 tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 286 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Skill: Brand Kit
Step 0 — is the kit here? This skill reads files from the kit. Check once:
ls ${CLAUDE_SKILL_DIR}/../../../tokens >/dev/null 2>&1 && echo KIT_OK || echo KIT_MISSINGOnKIT_MISSINGonly the skill folders were installed, which is whatnpx skills adddoes. Say so plainly, point the user atnpx ux-ui-agent-skills initor the plugin install, and stop. Do not guess the contents of a file you could not open.
Stand up the foundation (one token system everything renders from) before any screen. Get this right and every page stays consistent and themeable from one place.
Steps
- Brief Inference (mandatory) — name the industry, audience, the one mood adjective, and motion depth (
${CLAUDE_SKILL_DIR}/../../../taste/design-taste.md→ Brief Inference). Pick an anchoring archetype from${CLAUDE_SKILL_DIR}/../../../taste/aesthetic-systems.md. - Primitives — generate the brand color ramp in OKLCH (11 shades, consistent chroma) + a neutral ramp; verify the 500 shade ≥ 4.5:1 on white (text) and 600 ≥ 3:1 (UI) per
.claude/rules/tokens-and-color.md→ Color Generation. - Semantic layer — map roles to primitives:
action.primary/-hover/destructive,text.{primary,secondary,on-action,link},surface.{page,card,raised},border.{default,strong},feedback.{success,warning,error,info}— and the dark overrides (designed, not inverted). - Scales — Major Third type scale + composite text styles, 4px spacing scale, radius tiers, elevation, and
${CLAUDE_SKILL_DIR}/../../../tokens/motion.json-style durations/easings. - Emit the DTCG
${CLAUDE_SKILL_DIR}/../../../tokens/*.json(3-tier) + a singletheme.css(the one shared source,[data-theme="dark"]overrides). Optionally feed the token-build pipeline (token-buildskill) for other platforms.
Verification (definition of done)
python3 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_tokens.py— valid JSON, all aliases resolve.python3 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_contrast.py— required text/action/border pairs pass WCAG AA in light AND dark;border.strong≥ 3:1.python3 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_theme_refs.py— every componentvar(--…)resolves to the theme.- One theme, no per-page palettes; destructive = danger token (not primary); zero hardcoded values.
Output is a verified token foundation — the measurable part is provable (run
npm run verify). Brand "feel" still benefits from a human review against${CLAUDE_SKILL_DIR}/../../../taste/design-taste.md.
