from step8_daily_content_planning.platform_optimizer import PlatformOptimizer

# Use individual components
schedule_generator = DailyScheduleGenerator()
platform_optimizer = PlatformOptimizer()

# Generate schedules
daily_schedules = await schedule_generator.generate_daily_schedules(
    weekly_themes, platform_strategies, content_pillars, calendar_framework
)

# Optimize for platforms
optimized_schedules = await platform_optimizer.optimize_content_for_platforms(
    daily_schedules, platform_strategies, target_audience

## 🚨 **Error Handling**

### **Common Error Scenarios**

1. **Missing AI Services**
   ```python
   raise ImportError("Required AI services not available. Cannot proceed without real AI services.")
   ```

2. **Invalid Inputs**
   ```python
   raise ValueError("Weekly themes from Step 7 are required for daily content planning")
