$npx -y skills add educlopez/ui-craft --skill adaptResponsive layout pass covering breakpoints, touch targets, safe areas, and fluid type. Use when the UI has layout or touch issues on mobile/tablet, when adding a new screen that hasn't been tested across viewports, or when the user says "make it responsive" / "fix mobile layout"

| 3 | **Context:** this sub-skill is one lens of the broader `ui-craft` skill. If the `ui-craft` skill is also installed, read its SKILL.md first for Discovery + Anti-Slop + Craft Test, then apply the specific lens below. |

| 5 | Adapt the UI at the target the user described across devices. Load the `ui-craft` skill and read `references/responsive.md`. |

| 9 | **Checklist:** |
| 10 | |
| 11 | 1. **Breakpoints** — use project's existing system (Tailwind: `sm md lg xl`; CSS: container queries preferred over media queries for components). No magic widths. |
| 12 | 2. **Touch** — tap targets ≥ 44×44px (`min-h-11 min-w-11`). Touch zones don't overlap. `touch-action: manipulation` on interactive elements. |
| 13 | 3. **Safe areas** — `padding-top: env(safe-area-inset-top)` etc. on fixed headers/footers/FAB. Check iOS notch and Android gesture bar. |
| 14 | 4. **No horizontal scroll** at 320px. Test with devtools device mode. |
| 15 | 5. **Fluid type** — `clamp(1rem, 0.9rem + 0.5vw, 1.125rem)` for body where scale matters; fixed px for small UI text (labels, captions). |
| 16 | 6. **Container queries** — prefer `@container` over viewport media queries for component-level responsiveness. Components that live in sidebars and main content behave differently at the same viewport width. |
| 17 | 7. **Hover-less devices** — every hover affordance has a non-hover equivalent. `@media (hover: hover)` to scope desktop-only effects. |
| 18 | 8. **Density shifts with viewport** — honor `VISUAL_DENSITY` differently per breakpoint: |
| 19 | - `VISUAL_DENSITY ≤ 3` → fewer columns and wider spacing even at desktop widths. |
| 20 | - `VISUAL_DENSITY 8+` → honor dashboard density, but still respect touch/hover distinctions (touch targets stay ≥ 44px on mobile, hover affordances gated behind `@media (hover: hover)`). |
| 21 | - Mobile always trends toward 1 column and wider spacing regardless of the knob value. |
| 22 | 9. **Images** — `aspect-ratio` set; `srcset` + `sizes` for different viewports; `loading="lazy"` below the fold; `fetchpriority="high"` on hero. |
| 23 | 10. **Nav pattern** — desktop horizontal → mobile collapses (sheet, drawer, or bottom tabs). Never a hamburger on desktop unless the nav has > 7 top-level items. |
| 24 | |
| 25 | **Output**: edit code directly. Print the Review Format table of changes. Flag any responsive bugs you can't fix without more info (missing design for a breakpoint, unclear nav pattern). |
