# Convert PDF files to different formats

# This script demonstrates shell script support in skillkit.
# It reads JSON from stdin and performs format conversion.
#
# Environment variables available:
# - SKILL_NAME
# - SKILL_BASE_DIR
# - SKILL_VERSION
# - SKILLKIT_VERSION

# Read JSON input from stdin
read -r json_input

# Parse JSON using Python (for simplicity)

output_format=$(echo "$json_input" | python3 -c "import sys, json; data=json.load(sys.stdin); print(data.get('output_format', 'txt'))")

# Validate input
if [ -z "$input_file" ]; then
    echo '{"error": "Missing required argument: input_file"}' >&2
    exit 1
