🔧 Technical Stack

Container Architecture

# Base: Ruby 3.2.3 (for Jekyll compatibility)
# Added: Python 3 + pip + venv
# Environment: /opt/venv for Python isolation
# Dependencies: PyYAML for frontmatter parsing

Service Integration

# docker-compose.yml services:
# - jekyll: Jekyll development server
# - quest-validator: Python validation framework
# - Shared volumes for live code access
# - Environment isolation for clean execution

🚀 Usage Commands (Updated)

Individual Quest Validation

docker-compose run --rm quest-validator \
    /opt/venv/bin/python /app/test/quest-validator/quest_validator.py \
    /app/pages/_quests/your-quest.md

Batch Validation with Report

docker-compose run --rm quest-validator \
    /opt/venv/bin/python /app/test/quest-validator/quest_validator.py \
    -d /app/pages/_quests/ --report /app/reports/validation.json

Automated Test Suite

./test/quest-validator/test-validator.sh

📊 Quality Improvements

Before (Virtual Environment)
