Art Skill Contents: Ideal State · Intent Routing · Safety gates · Tool contract · Data & Config · Gotchas · Examples Generates static visual content across 20+ formats — blog headers, technical and architecture diagrams, frameworks, taxonomies, timelines, comparisons, stat cards, comics, icons, wallpapers, D3 charts, Mermaid diagrams — using Flux and Nano Banana Pro (Gemini 3 Pro). Every request routes through a named intent that encodes the technique and palette, then calls Generate.ts with --intent= plus model/size/output flags, and Generate.ts itself enforces that the intent was followed. Output defaults to $LIFEOSDOWNLOADSDIR (default /Downloads/ when unset) unless --output names another path, so every intent passes --output into a working directory outside Downloads (§ Output staging).
