"Browse Amazon for headphones using legacy system"
# System: Uses step-by-step legacy approach

# Secure-only approach
"Browse secure banking site for account info"
# System: Enhanced generation with maximum security isolation

Configuration

Browser Behavior

# Fine-tune smolagents automation in agent config
automation_config:
  enhanced_code_generation: true    # Enable smolagents approach
  secure_sandbox_execution: true   # Enable secure execution
  error_recovery_enabled: true     # Enable intelligent recovery
  max_retries_per_task: 3          # Retry attempts with regeneration
  show_browser: false              # Default headless mode
  code_optimization_level: standard # Code optimization setting

Cost Controls

# Budget management for enhanced automation
cost_controls:
  max_cost_per_task: 0.20           # Stop if exceeding 20¢
  prefer_batch_operations: true    # Favor code generation over step-by-step
  enable_pattern_caching: true     # Cache successful automation scripts
  track_spending: true              # Real-time cost monitoring
  daily_budget: 5.00                # Daily automation budget

Troubleshooting

Browser Not Showing

Problem: --show-browser flag not working

Solutions:

# Check environment variable
echo $WYN360_BROWSER_SHOW

# Set explicitly
export WYN360_BROWSER_SHOW=1
wyn360

# Or use CLI flag (overrides environment)
wyn360 --show-browser

Code Generation Issues

Problem: Generated automation scripts fail to execute

Solutions:

1. Enable browser visibility: wyn360 --show-browser
2. Check error recovery: Review intelligent error analysis
3. Verify sandbox security: Ensure safe execution environment
4. Enable pattern caching: Reuse successful automation patterns

High Costs

Problem: Automation costs more than expected

Solutions:

1. Check approach distribution: Use /tokens command
2. Enable pattern caching: Set WYN360_PATTERN_CACHING=true
3. Monitor error recovery: Too many regeneration attempts?
4. Use batch operations: Combine multiple actions in single script

Authentication Issues

Problem: Can't access logged-in content

Solutions:

1. Login first: Use explicit login request
2. Check session: Sessions last 30 minutes
3. Clear cache: If cookies are corrupted
4. Manual intervention: Use show-browser for complex auth

Best Practices

1. Optimize for Enhanced Code Generation

# Good: Clear, specific automation goals
"Find product price on Amazon product page"

# Better: Detailed task descriptions
"Search Amazon for wireless mouse under $20 with good reviews and extract the cheapest option"

# Best: Specific and comprehensive
"Browse Amazon, search for 'wireless mouse', apply price filter under $20, filter by 4+ star ratings, and return the top 3 cheapest options with details"

2. Use Browser Visibility Strategically

# Development & debugging
wyn360 --show-browser

# Production & scripts with enhanced automation
wyn360  # headless for optimal performance

# Specific debugging with code generation
"Browse to checkout and show me the generated automation script"

3. Leverage Intelligent Recovery

# Enhanced system automatically handles most errors:
"Browse complex e-commerce site for product comparison"
→ System: Generates code, detects errors, regenerates improved code
→ Success: Automatic recovery with learning applied

4. Monitor Performance & Patterns

# Regular performance checking
/tokens

# Enable pattern caching for better performance
export WYN360_PATTERN_CACHING=true

# Optimize code generation level
export WYN360_CODE_OPTIMIZATION=advanced
