What it does

Token Build is an agent skill from plugin87/ux-ui-agent-skills. Set up or run the token build pipeline — transform the DTCG tokens/.json (source of truth) into platform artifacts (CSS variables, Tailwind @theme, JS/TS, iOS Asset Catalog, Android, Compose) with Style Dictionary / Tokens Studio / W3C DTCG export. Use when the user wants to generate platform theme files from tokens, wire token CI, or multi-platform token output.

Its SKILL.md is about 590 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, CSS and styling and CI/CD. It works with Tailwind CSS, Android and iOS. 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 to generate platform theme files from tokens
  • Multi-platform token output

Example prompts

  • “/token-build”

Requirements

  • Python 3
  • Node.js

Workflow steps

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

  1. Read ${CLAUDE_SKILL_DIR}/../../../workflows/token-build.md (architecture, tool options, resolution rules, output targets, CI).
  2. Pick the tool: Style Dictionary (multi-platform, the default), Tokens Studio (Figma-owned tokens — pairs with figma-integration), W3C DTCG…
  3. Honor the resolution rules: resolve aliases to final values per platform; expose semantic + component tokens (primitives stay internal)…
  4. Generate the requested target(s): CSS :root vars, Tailwind v4 @theme, typed JS/TS, iOS Asset Catalog + Color.DS/Spacing, Android…
  5. Wire CI: on ${CLAUDE_SKILL_DIR}/../../../tokens/*.json change, run ${CLAUDE_SKILL_DIR}/../../../scripts/validate_tokens.py, regenerate…

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

Token Build loads about 585 tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 221 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~585

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
Set up or run the token build pipeline — transform the DTCG tokens/*.json (source of truth) into platform artifacts (CSS variables, Tailwind @theme, JS/TS, iOS Asset Catalog, Android, Compose) with Style Dictionary / Tokens Studio / W3C DTCG export. Use when the user wants to generate platform theme files from tokens, wire token CI, or multi-platform token output.

Skill: Token Build

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.

Turn the DTCG token source of truth into platform-ready outputs. Tokens are authored once; every platform output is generated.

Steps

  1. Read ${CLAUDE_SKILL_DIR}/../../../workflows/token-build.md (architecture, tool options, resolution rules, output targets, CI).
  2. Pick the tool: Style Dictionary (multi-platform, the default), Tokens Studio (Figma-owned tokens — pairs with figma-integration), W3C DTCG export, or a small custom script (model on ${CLAUDE_SKILL_DIR}/../../../scripts/validate_tokens.py).
  3. Honor the resolution rules: resolve aliases to final values per platform; expose semantic + component tokens (primitives stay internal); emit base + dark/brand/density overrides (${CLAUDE_SKILL_DIR}/../../../tokens/theming.json) as deltas only; format by $type.
  4. Generate the requested target(s): CSS :root vars, Tailwind v4 @theme, typed JS/TS, iOS Asset Catalog + Color.DS/Spacing, Android colors.xml/Compose theme.
  5. Wire CI: on ${CLAUDE_SKILL_DIR}/../../../tokens/*.json change, run ${CLAUDE_SKILL_DIR}/../../../scripts/validate_tokens.py, regenerate, fail if committed artifacts are stale; gate colors with ${CLAUDE_SKILL_DIR}/../../../scripts/contrast.py.

Verification (definition of done)

  • python3 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_tokens.py passes (no unresolved aliases).
  • Regenerating produces no diff vs. committed artifacts.
  • Dark/brand/density outputs contain only deltas, not full duplicates.
