## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

### App Icon Generation

Generate all required sizes from a single 1024x1024 source icon.

### iOS / macOS Icon Sizes

#!/bin/bash
# generate-app-icons.sh <source-1024.png> <output-dir>
SOURCE="$1"
OUTDIR="${2:-.}"
mkdir -p "$OUTDIR"

SIZES=(16 20 29 32 40 48 58 60 64 76 80 87 120 128 152 167 180 256 512 1024)
for SIZE in "${SIZES[@]}"; do
  sips -z $SIZE $SIZE "$SOURCE" --out "$OUTDIR/icon-${SIZE}x${SIZE}.png" 2>/dev/null
done
echo "Generated ${#SIZES[@]} icon sizes in $OUTDIR"

### Android Icon Sizes

# Android adaptive icon sizes
declare -A ANDROID_SIZES=(
  ["mdpi"]=48 ["hdpi"]=72 ["xhdpi"]=96
  ["xxhdpi"]=144 ["xxxhdpi"]=192
)
for DENSITY in "${!ANDROID_SIZES[@]}"; do
  SIZE=${ANDROID_SIZES[$DENSITY]}
  mkdir -p "res/mipmap-$DENSITY"
  sips -z $SIZE $SIZE "$SOURCE" --out "res/mipmap-$DENSITY/ic_launcher.png"
done

### Favicon Generation

#!/bin/bash
# generate-favicons.sh <source.png> <output-dir>
SOURCE="$1"
OUTDIR="${2:-.}"
mkdir -p "$OUTDIR"

# Standard web favicons
sips -z 16 16 "$SOURCE" --out "$OUTDIR/favicon-16x16.png"
sips -z 32 32 "$SOURCE" --out "$OUTDIR/favicon-32x32.png"
sips -z 180 180 "$SOURCE" --out "$OUTDIR/apple-touch-icon.png"

sips -z 512 512 "$SOURCE" --out "$OUTDIR/android-chrome-512x512.png"

# ICO file (requires ImageMagick)
magick "$OUTDIR/favicon-16x16.png" "$OUTDIR/favicon-32x32.png" "$OUTDIR/favicon.ico"

echo "Favicons generated in $OUTDIR"

### Color Palette Generator

Given a primary color, generate a full palette:

// HSL-based palette generation
function generatePalette(hue, saturation = 70) {
  return {
    50:  \`hsl(${hue}, ${saturation}%, 97%)\`,
    100: \`hsl(${hue}, ${saturation}%, 94%)\`,
    200: \`hsl(${hue}, ${saturation}%, 86%)\`,
    300: \`hsl(${hue}, ${saturation}%, 74%)\`,
    400: \`hsl(${hue}, ${saturation}%, 62%)\`,
    500: \`hsl(${hue}, ${saturation}%, 50%)\`,  // Primary
    600: \`hsl(${hue}, ${saturation}%, 42%)\`,
    700: \`hsl(${hue}, ${saturation}%, 34%)\`,
    800: \`hsl(${hue}, ${saturation}%, 26%)\`,
    900: \`hsl(${hue}, ${saturation}%, 18%)\`,
    950: \`hsl(${hue}, ${saturation}%, 10%)\`,
  };
}
