# Skill: Token Build Turn the DTCG token source of truth into platform-ready outputs. Tokens are authored once; every platform output is generated. ## Steps 1. Read `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 `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 (`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 `tokens/*.json` change, run `scripts/validate_tokens.py`, regenerate, fail if committed artifacts are stale; gate colors with `scripts/contrast.py`. ## Verification (definition of done) - `python3 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.
