/check-images

Check Cloudflare Images Configuration

Run a complete health check of your Cloudflare Images setup including API connectivity, authentication, transformations, variants, and quota.

What This Command Does

When you run /check-images, Claude will:

1. Verify environment variables are set correctly
2. Test API connectivity
3. Validate authentication (account ID + API token)
4. Check if transformations are enabled for zone
5. List all configured variants
6. Show storage quota and usage
7. Display recent images
8. Verify CDN caching status

Usage

/check-images

No arguments required - the command will automatically discover configuration from environment variables.

Implementation

Run the following checks in sequence:

1. Verify Environment Variables

echo "📋 Checking environment variables..."

if [ -z "$CF_ACCOUNT_ID" ]; then
  echo "❌ CF_ACCOUNT_ID not set"
  echo "   Set in .env: CF_ACCOUNT_ID=your_account_id"
  exit 1
else
  echo "✅ CF_ACCOUNT_ID: ${CF_ACCOUNT_ID:0:8}..."
fi

if [ -z "$CF_API_TOKEN" ]; then
  echo "❌ CF_API_TOKEN not set"
  echo "   Set in .env: CF_API_TOKEN=your_api_token"
  exit 1
else
  echo "✅ CF_API_TOKEN: ${CF_API_TOKEN:0:10}..."
fi

if [ -z "$CF_ACCOUNT_HASH" ]; then
  echo "⚠️  CF_ACCOUNT_HASH not set (optional for delivery URLs)"
else
  echo "✅ CF_ACCOUNT_HASH: ${CF_ACCOUNT_HASH}"
fi

echo ""

2. Test API Connectivity

echo "🔌 Testing API connectivity..."

API_RESPONSE=$(curl -s -o /dev/null -w "%{http_code}" \
  "https://api.cloudflare.com/client/v4/accounts/${CF_ACCOUNT_ID}/images/v1" \
  -H "Authorization: Bearer ${CF_API_TOKEN}")

if [ "$API_RESPONSE" = "200" ]; then
  echo "✅ API connectivity: OK"
else
  echo "❌ API connectivity failed (HTTP $API_RESPONSE)"
  echo "   Verify CF_ACCOUNT_ID and CF_API_TOKEN are correct"
  exit 1
fi

echo ""

3. Validate Authentication

echo "🔑 Validating authentication..."

AUTH_RESULT=$(curl -s \
  "https://api.cloudflare.com/client/v4/accounts/${CF_ACCOUNT_ID}/images/v1" \
  -H "Authorization: Bearer ${CF_API_TOKEN}")

AUTH_SUCCESS=$(echo "$AUTH_RESULT" | jq -r '.success')

if [ "$AUTH_SUCCESS" = "true" ]; then
  echo "✅ Authentication: Valid"

  # Check permissions
  IMAGES_COUNT=$(echo "$AUTH_RESULT" | jq -r '.result.images | length')
  echo "   Images accessible: $IMAGES_COUNT"
else
  echo "❌ Authentication failed"
  ERRORS=$(echo "$AUTH_RESULT" | jq -r '.errors[].message')
  echo "   Error: $ERRORS"
  exit 1
fi

echo ""

4. Check Transformations Status

echo "🎨 Checking transformations..."

# Note: Transformations are always enabled for Cloudflare Images
# This checks if zone-based transformations are available

if [ ! -z "$CF_ZONE_ID" ]; then
  POLISH_STATUS=$(curl -s \
    "https://api.cloudflare.com/client/v4/zones/${CF_ZONE_ID}/settings/polish" \
    -H "Authorization: Bearer ${CF_API_TOKEN}" \
    | jq -r '.result.value')

  echo "✅ Zone Polish: $POLISH_STATUS"
else
  echo "ℹ️  Zone transformations: Not configured (CF_ZONE_ID not set)"
  echo "   Cloudflare Images transformations are always available"
fi

echo ""

5. List Variants

echo "📐 Listing configured variants..."

VARIANTS=$(curl -s \
  "https://api.cloudflare.com/client/v4/accounts/${CF_ACCOUNT_ID}/images/v1/variants" \
  -H "Authorization: Bearer ${CF_API_TOKEN}")

VARIANTS_SUCCESS=$(echo "$VARIANTS" | jq -r '.success')

if [ "$VARIANTS_SUCCESS" = "true" ]; then
  VARIANT_COUNT=$(echo "$VARIANTS" | jq -r '.result.variants | length')
  echo "✅ Variants configured: $VARIANT_COUNT/100"

  if [ "$VARIANT_COUNT" -gt 0 ]; then
    echo ""
    echo "   Configured variants:"
    echo "$VARIANTS" | jq -r '.result.variants[] | "   • \(.id): \(.options.width // "auto")x\(.options.height // "auto") (\(.options.fit // "scale-down"))"'
  else
    echo "   No custom variants configured (using flexible transformations)"
  fi
else
  echo "⚠️  Could not list variants"
fi

echo ""

6. Show Storage Quota and Usage

echo "💾 Checking storage quota..."

STATS=$(curl -s \
  "https://api.cloudflare.com/client/v4/accounts/${CF_ACCOUNT_ID}/images/v1/stats" \
  -H "Authorization: Bearer ${CF_API_TOKEN}")

STATS_SUCCESS=$(echo "$STATS" | jq -r '.success')

if [ "$STATS_SUCCESS" = "true" ]; then
  IMAGES_COUNT=$(echo "$STATS" | jq -r '.result.count.current')
  IMAGES_ALLOWED=$(echo "$STATS" | jq -r '.result.count.allowed')

  echo "✅ Storage usage:"
  echo "   Images stored: $IMAGES_COUNT"

  if [ "$IMAGES_ALLOWED" != "null" ]; then
    PERCENT_USED=$(echo "scale=1; $IMAGES_COUNT * 100 / $IMAGES_ALLOWED" | bc)
    echo "   Quota: $IMAGES_COUNT / $IMAGES_ALLOWED ($PERCENT_USED%)"
  else
    echo "   Quota: Unlimited (paid plan)"
  fi
else
  echo "⚠️  Could not retrieve storage stats"
fi

echo ""

7. Display Recent Images

echo "🖼️  Recent images..."

RECENT=$(curl -s \
  "https://api.cloudflare.com/client/v4/accounts/${CF_ACCOUNT_ID}/images/v1?per_page=5" \
  -H "Authorization: Bearer ${CF_API_TOKEN}")

RECENT_SUCCESS=$(echo "$RECENT" | jq -r '.success')

if [ "$RECENT_SUCCESS" = "true" ]; then
  IMAGE_COUNT=$(echo "$RECENT" | jq -r '.result.images | length')

  if [ "$IMAGE_COUNT" -gt 0 ]; then
    echo "✅ Last $IMAGE_COUNT uploaded images:"
    echo ""
    echo "$RECENT" | jq -r '.result.images[] | "   ID: \(.id)\n   Uploaded: \(.uploaded)\n   Filename: \(.filename)\n   Variants: \(.variants | length)\n"'
  else
    echo "ℹ️  No images uploaded yet"
  fi
else
  echo "⚠️  Could not retrieve recent images"
fi

echo ""

8. Test Image Delivery (If Images Exist)

echo "🌐 Testing image delivery..."

if [ "$IMAGE_COUNT" -gt 0 ] && [ ! -z "$CF_ACCOUNT_HASH" ]; then
  # Get first image ID
  SAMPLE_ID=$(echo "$RECENT" | jq -r '.result.images[0].id')

  # Test delivery
  DELIVERY_STATUS=$(curl -s -o /dev/null -w "%{http_code}" \
    "https://imagedelivery.net/${CF_ACCOUNT_HASH}/${SAMPLE_ID}/public")

  if [ "$DELIVERY_STATUS" = "200" ]; then
    echo "✅ Image delivery: Working"
    echo "   Test URL: https://imagedelivery.net/${CF_ACCOUNT_HASH}/${SAMPLE_ID}/public"

    # Check CDN caching
    CACHE_STATUS=$(curl -s -I "https://imagedelivery.net/${CF_ACCOUNT_HASH}/${SAMPLE_ID}/public" \
      | grep -i "cf-cache-status" | awk '{print $2}' | tr -d '\r')

    if [ ! -z "$CACHE_STATUS" ]; then
      echo "   CDN Cache: $CACHE_STATUS"
    fi
  else
    echo "❌ Image delivery failed (HTTP $DELIVERY_STATUS)"
    echo "   Verify CF_ACCOUNT_HASH is correct"
  fi
elif [ "$IMAGE_COUNT" = 0 ]; then
  echo "ℹ️  No images to test delivery"
elif [ -z "$CF_ACCOUNT_HASH" ]; then
  echo "ℹ️  Cannot test delivery (CF_ACCOUNT_HASH not set)"
fi

Troubleshooting

Error: CF_ACCOUNT_ID not set

Solution: Add to .env file:

CF_ACCOUNT_ID=your_account_id_here

Get account ID from Cloudflare dashboard: Account > Workers & Pages > Account ID

Error: API connectivity failed (HTTP 401)

Solution: Invalid API token. Create new token:

1. Go to Cloudflare dashboard
2. My Profile > API Tokens > Create Token
3. Use "Edit Cloudflare Images" template
4. Copy token to .env: CF_API_TOKEN=your_token_here

Error: Authentication failed

Solution: Verify permissions:

• Token must have "Cloudflare Images:Edit" permission
• Token must be scoped to correct account

Warning: No custom variants configured

Solution: This is normal if using flexible transformations. Create variants with:

/generate-variant

• /validate-config - Validate wrangler.jsonc and bindings
