design-import
Scaffolds React components out of an exported Claude Design handoff bundle and stops at files on disk: no stories, no tests, no pull request. Takes a claude.ai/design URL or a local bundle file, validates the tarball layout, reconciles the bundle's design tokens against the project's, deduplicates every proposed component against the existing codebase via component-search, pipes the survivors through the design-to-code pipeline, and records provenance so a later re-export can be diffed for drift. This is the import step by itself. Use it when you want the scaffolded code sitting in the working tree to inspect or edit yourself; when that same scaffold should carry on through test generation, browser verification and an opened PR, run /ork:design-ship instead.

Output: a severity-ranked review (blocking → major → minor) with file:line, concrete fixes, residual risks and a one-line verdict, in the conversation's language (technical tokens stay in English). Companion of the ultra11y skill (full audits, reports, PRD, RGAA packs). Triggers: 'review a11y', 'a11y review', 'accessibility review'.
