What it does

Design Tokens is an agent skill from plugin87/ux-ui-agent-skills. Generate, extend, or audit design tokens in DTCG format with the 3-tier architecture (primitive → semantic → component). Use when the user wants a color palette, type scale, spacing/shadow/radius/motion tokens, multi-brand theming, or wants to validate token files. Covers colors, typography, spacing, shadows, borders, breakpoints, motion, gradients, opacity, blur, sizing, states, theming.

Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering Design tokens, Theming and dark mode and Typography. The repository describes itself as: Turn Claude into a senior design architect: DTCG tokens, 52 components, WCAG 2.2 AA-AAA, 138 design systems, any-framework code, and 50 objective gates that fail the build… The licence is MIT.

When your agent uses it

  • The user wants a color palette
  • Spacing/shadow/radius/motion tokens
  • Multi-brand theming
  • Wants to validate token files

Example prompts

  • “/design-tokens”

Requirements

  • Python 3
  • Node.js

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Read .claude/rules/tokens-and-color.md → "Token System" + "Color Guidelines" and .claude/rules/typography-and-spacing.md for the rules…
  2. Read the relevant existing files in tokens/ to match structure: colors.json, typography.json, spacing.json, shadows.json, borders.json…
  3. Generate/extend tokens
  4. Validate: run python3 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_tokens.py (JSON validity + alias resolution).

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:

    • npx
    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, 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

Design Tokens loads about 517 tokens when it runs. Until then it costs about 101 tokens; SKILL.md has 182 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~101
When it runs · the whole SKILL.md, loaded when a task matches
~517

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.

description
Generate, extend, or audit design tokens in DTCG format with the 3-tier architecture (primitive → semantic → component). Use when the user wants a color palette, type scale, spacing/shadow/radius/motion tokens, multi-brand theming, or wants to validate token files. Covers colors, typography, spacing, shadows, borders, breakpoints, motion, gradients, opacity, blur, sizing, states, theming.

Skill: Design Tokens

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_MISSING On KIT_MISSING only the skill folders were installed, which is what npx skills add does. Say so plainly, point the user at npx ux-ui-agent-skills init or the plugin install, and stop. Do not guess the contents of a file you could not open.

Produce and maintain DTCG ($type/$value) tokens following the project's 3-tier system.

Steps

  1. Read .claude/rules/tokens-and-color.md → "Token System" + "Color Guidelines" and .claude/rules/typography-and-spacing.md for the rules (4px base, Major Third scale, OKLCH palette generation, dark-mode-at-semantic-layer).
  2. Read the relevant existing files in tokens/ to match structure: colors.json, typography.json, spacing.json, shadows.json, borders.json, breakpoints.json, motion.json, gradients.json, opacity.json, blur.json, sizing.json, states.json, theming.json.
  3. Generate/extend tokens:
    • Primitives = raw values (never used directly). Semantic = purpose aliases. Component = component-scoped.
    • New palettes: generate 11 OKLCH shades; verify 500 ≥ 4.5:1 on white (text), 600 ≥ 3:1 (UI) using the a11y-audit skill / ${CLAUDE_SKILL_DIR}/../../../scripts/contrast.py.
    • Multi-brand/density → theming.json.
  4. Validate: run python3 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_tokens.py (JSON validity + alias resolution).

Output

DTCG JSON. Preserve $description on every token. Reference, never hardcode.
