Agent Skills: Gallery Management

Gallery Management

Manage local gallery content before uploading to S3.

Arguments

• $ARGUMENTS - Command to execute: list, create, validate, organize, or stats

Commands

List Galleries

Show all local galleries and their status:

ls -la content/galleries/

Create New Gallery

Create a properly structured gallery folder:

GALLERY_ID=$1  # e.g., "portrait-002"
CATEGORY=$2    # brands, portraits, events, custom

mkdir -p content/galleries/$GALLERY_ID/{originals,processed,thumbnails,blur}

# Create gallery metadata file
cat > content/galleries/$GALLERY_ID/metadata.json << 'EOF'
{
  "id": "GALLERY_ID_PLACEHOLDER",
  "title": "",
  "category": "CATEGORY_PLACEHOLDER",
  "description": "",
  "isPublic": true,
  "isClientGallery": false,
  "createdAt": "TIMESTAMP_PLACEHOLDER"
}
EOF

Validate Gallery Images

Check images meet requirements before upload:

GALLERY_PATH=$1  # e.g., "content/galleries/portrait-002"

# Check for supported formats
find $GALLERY_PATH/originals -type f \( \
  -name "*.jpg" -o -name "*.jpeg" -o -name "*.png" \
  -o -name "*.webp" -o -name "*.heic" -o -name "*.heif" \
  -o -name "*.tiff" -o -name "*.tif" \
\) -print

# Check for unsupported formats (should be empty)
find $GALLERY_PATH/originals -type f \( \
  -name "*.cr2" -o -name "*.nef" -o -name "*.arw" \
  -o -name "*.gif" -o -name "*.bmp" -o -name "*.psd" \
\) -print

# Check file sizes (warn if > 50MB)
find $GALLERY_PATH/originals -type f -size +50M -print

# Count total images
find $GALLERY_PATH/originals -type f \( -name "*.jpg" -o -name "*.jpeg" -o -name "*.png" \) | wc -l

Organize Gallery

Rename files with consistent naming and ordering:

GALLERY_PATH=$1

# Generate sequential names while preserving extension
cd $GALLERY_PATH/originals
count=1
for file in *.{jpg,jpeg,png,webp}; do
  if [ -f "$file" ]; then
    ext="${file##*.}"
    newname=$(printf "img-%03d.%s" $count "$ext")
    mv "$file" "$newname"
    ((count++))
  fi
done

Gallery Statistics

Show comprehensive stats for a gallery:

GALLERY_PATH=$1

echo "=== Gallery Statistics ==="
echo "Path: $GALLERY_PATH"
echo ""

# Count by type
echo "Image counts:"
echo "  JPG/JPEG: $(find $GALLERY_PATH/originals -name "*.jpg" -o -name "*.jpeg" | wc -l)"
echo "  PNG: $(find $GALLERY_PATH/originals -name "*.png" | wc -l)"
echo "  WebP: $(find $GALLERY_PATH/originals -name "*.webp" | wc -l)"
echo "  HEIC: $(find $GALLERY_PATH/originals -name "*.heic" -o -name "*.heif" | wc -l)"
echo ""

# Total size
echo "Total size:"
du -sh $GALLERY_PATH/originals

# Processed status
echo ""
echo "Processing status:"
echo "  Processed variants: $(find $GALLERY_PATH/processed -type f 2>/dev/null | wc -l)"
echo "  Thumbnails: $(find $GALLERY_PATH/thumbnails -type f 2>/dev/null | wc -l)"
echo "  Blur placeholders: $(find $GALLERY_PATH/blur -type f 2>/dev/null | wc -l)"

Directory Structure

Expected gallery structure:

content/galleries/{gallery-id}/
├── metadata.json      # Gallery metadata
├── originals/         # Original uploaded images
│   ├── img-001.jpg
│   ├── img-002.jpg
│   └── ...
├── processed/         # Generated WebP variants
│   └── img-001/
│       ├── 320w.webp
│       ├── 640w.webp
│       └── ...
├── thumbnails/        # Generated thumbnails
│   └── img-001/
│       ├── sm.webp
│       ├── md.webp
│       └── lg.webp
└── blur/             # Blur placeholders
    ├── img-001.txt
    └── ...

Workflow Integration

This skill works with other skills in this order:

1. /gallery-manage create - Create new gallery structure
2. Copy images to originals/ folder
3. /gallery-manage validate - Check images meet requirements
4. /optimize-images - Generate variants and thumbnails
5. /sync-content - Upload to S3
6. /db-seed or API call - Create gallery record in DynamoDB
