Agent Skills: plan-preview

Generate a standalone HTML preview of any project plan — ROADMAP, phases, build sequence, architecture decisions — as a beautiful, navigable single-file document. Use this skill whenever the user asks to preview a plan, generate an HTML plan, visualize a roadmap, create a shareable plan document, says 'plan preview', 'HTML plan', 'preview my plan', 'share this plan', 'make the plan visual', 'deploy the plan', or wants to push a plan to Vercel or Netlify or Github pages for sharing.
