@designci/core

The Design CI engine: domain model, value normalization, and the deterministic rule runner. The designci CLI, the Figma plugin, the GitHub Action and the dashboard are all built on this package — none of them reimplement any of it.

import { allRules, runCheck } from '@designci/core'

const result = runCheck({ snapshots, rules: allRules, config })
result.health.overall  // one health score, computed here and nowhere else

Pure throughout: no filesystem, no network, no clock. Identical inputs serialize to byte-identical JSON.

Most users want the CLI: npx designci check.
