Essential Tools

debugging:
  analysis:
    - error-parsing      # Parse and analyze errors
    - stack-analysis    # Trace execution flow
    - log-mining        # Extract patterns from logs
  
  interactive:
    - debugger-integration  # IDE debugger support
    - repl-debugging       # Interactive exploration
    - time-travel         # Replay debugging
  
  monitoring:
    - runtime-inspection  # Live system analysis
    - performance-profiling # Identify bottlenecks
    - memory-analysis    # Detect leaks

Common Debugging Patterns

Error Analysis Pattern

// Structured error analysis
interface DebugContext {
  error: Error
  stackTrace: string[]
  environment: Record<string, any>
  relatedCode: string[]
  hypotheses: string[]
}
 
async function analyzeError(context: DebugContext) {
  // AI analyzes error context
  // Suggests potential causes
  // Recommends fixes
}

Systematic Debugging

1. Reproduce - Consistently reproduce the issue
2. Isolate - Narrow down the problem area
3. Hypothesize - Form theories about the cause
4. Test - Validate or invalidate hypotheses
5. Fix - Implement and verify the solution
