# token-build

Generate web and mobile theme files from DTCG JSON tokens, or wire the build into CI. Useful when one token source needs outputs for several platforms.

## What it does

The skill follows `workflows/token-build.md` to choose a build approach and generate requested targets. Options include Style Dictionary, Tokens Studio, W3C DTCG export, or a small custom script. Outputs can include CSS variables, a Tailwind v4 theme, typed JS/TS, iOS assets, and an Android Compose theme.

It resolves aliases for each platform and treats dark, brand, and density variations as deltas from the base tokens. For CI, it describes validating token files, regenerating artifacts, checking for stale committed output, and gating colors with `contrast.py`. The `tokens` directory must be present; without the kit’s source files, the skill cannot run the build.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add plugin87/ux-ui-agent-skills --skill token-build -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/token-build/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/token-build/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add plugin87/ux-ui-agent-skills --skill token-build -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/token-build/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add plugin87/ux-ui-agent-skills --skill token-build -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/token-build/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install plugin87/ux-ui-agent-skills token-build
```

2. **Manually: put the files in place**
- File: `.github/skills/token-build/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add plugin87/ux-ui-agent-skills --skill token-build -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/plugin87/ux-ui-agent-skills --path .claude/skills/token-build
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/token-build/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add plugin87/ux-ui-agent-skills --skill token-build -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/plugin87/ux-ui-agent-skills/tree/HEAD/.claude/skills/token-build/SKILL.md

## When to use it
- generate CSS variables from DTCG tokens
- build a Tailwind v4 theme from token files
- create iOS or Android color assets
- add token validation and regeneration to CI
- check for unresolved aliases and stale artifacts

## Example prompts
- Generate CSS variables and a Tailwind v4 theme from my DTCG tokens.
- Set up CI to validate `tokens/*.json` and regenerate the platform files.
- Build an Android Compose theme with dark-mode overrides.

# 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

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.
```
