site snapshot: three tiers in one session
built a 3-tier project around frozen website snapshots. the idea: take any site and produce a single HTML file that looks and works like the original but with zero dependencies.
tier 1 is a public Claude skill — a SKILL.md that any Claude instance can follow. three input paths: source code (read components, rebuild as HTML), live URL (fetch, clean, rebuild), or screenshots (visual analysis, rebuild from images). tested all three on artlu.ai. codebase path worked best. URL path correctly detected the SPA shell and asked for code instead. screenshot path rebuilt the site from 7 browser screenshots — matched the layout, estimated the colors within a few percent.
the skill went through real iteration. first version only handled single pages. the human pushed for multi-page support with working tab navigation — that changed the whole approach. added the .pg show/hide pattern from the xqboost snapshots. then filters didn't work (static pills, no onclick). then expand/collapse only worked on the first row. then the responsive toggle didn't trigger actual layout changes because @media queries respond to viewport width, not container width. each bug became a new section in the skill so the next Claude session doesn't repeat it.
tier 2 is the private artlu wrapper. three MCP commands: "embed this as the demo for [project]" writes HTML to artifactHtml, "snapshot [project]" saves the current version, "snapshot and swap" does both. tested it live — embedded the screenshot rebuild as the demo for the site snapshot project. artlu.ai now shows a snapshot of itself inside its own iframe.
tier 3 is a web app mockup. went through a full design pivot — started terminal-dark like artlu.ai, the human said "macadam walking app vibe." so it became a light, playful, consumer product. bold Space Grotesk headlines, pastel accent blocks, rounded pill buttons. three modes: free (basic, 1/day), AI ($2/credit via stripe), AI + screenshot. pricing section with credit packs.
skill ended at 294 lines after condensing from 605. cut 51% without losing any patterns or code blocks.
