Design Extract

Design extract

Spec §10 / §21.3.2: tokens scattered across a repo's CSS / theme files / Tailwind config / styled-components helpers / SCSS partials need to be lifted into one bag before token-map can crosswalk them onto the active OD design system. This atom does the lifting; the input shape is intentionally generic so the same atom serves both code-migration and figma-migration when fed different sources.

Inputs

• code/index.json from code-import (code-migration), OR
• figma/tree.json from figma-extract (figma-migration), OR
• A folder of screenshot images (tune-collab quick-tune flows).

Output

project-cwd/
└── code/
    └── tokens.json     # { colors[], typography[], spacing[], radius[], shadow[] }

Each token entry carries:

{
  "kind":     "color",
  "name":     "primary-500",     // optional source name
  "value":    "#5b8def",          // canonical value
  "sources": ["styles/global.css:42", "tailwind.config.js:24"],
  "usage":   ["Header.tsx", "Footer.tsx"]
}

sources[] and usage[] are the audit trail token-map.unmatched.json references when a target token can't be found.

Convergence

The atom completes when code/tokens.json exists. Empty token bags emit a warning event but do not abort — token-map handles the empty case by skipping its mapping pass.

Anti-patterns the prompt fragment forbids

• Hard-coded hex values inside JSX literals (color: '#fff') are tokens for this atom's purposes; record them with kind:'color' and a synthetic name so they don't disappear into the noise.
• Tailwind utility scans must dedupe palette references against the active theme — never list bg-blue-500 and bg-blue-600 as one token.

Status

Implemented by the daemon runner in apps/daemon/src/plugins/atoms/design-extract.ts. It scans the indexed source files, extracts CSS, Tailwind, and JavaScript token evidence, and writes code/tokens.json.
