The 'design' plugin lives in anthropics/knowledge-work-plugins (same marketplace as #42 product-management), not claude-plugins-official (which carries only frontend-design). Verified post-reload against the marketplace manifest. Pre-push fixup of 621498a's own error - v2.8/v3.8/v2.8 unchanged. Tooling 4.21 also completes the capability list (+Design System Management, +Dev Handoff). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
