Debug Issue

Systematically debug and diagnose the reported problem.

Problem Description

$ARGUMENTS

Debugging Process

1. Reproduce the Issue

   • Get exact steps to reproduce
   • Verify you can see the same problem
   • Note any error messages or logs
   • Document the expected vs actual behavior

2. Gather Information

   # Check recent changes
   git log --oneline -10
   
   # Look for error patterns in logs
   # Search for related error messages
   

3. Isolate the Problem

   • Binary Search: Comment out code sections to narrow down
   • Git Bisect: Find when the bug was introduced
   • Logging: Add strategic log statements
   • Debugger: Set breakpoints if applicable

4. Common Debugging Strategies

   For Runtime Errors

   • Read the full stack trace
   • Identify the exact line causing the error
   • Check variable values at that point
   • Verify assumptions about data types

   For Logic Errors

   • Add print/log statements to trace execution
   • Verify each step produces expected results
   • Check boundary conditions
   • Test with minimal reproducible example

   For Performance Issues

   • Add timing measurements
   • Check for N+1 queries
   • Look for inefficient algorithms
   • Profile if necessary

   For Integration Issues

   • Verify external service is accessible
   • Check authentication/credentials
   • Validate request/response formats
   • Test with curl/Postman first

5. Root Cause Analysis

   • Why did this happen?
   • Why wasn't it caught earlier?
   • Are there similar issues elsewhere?
   • How can we prevent this class of bugs?

6. Implement Fix

   • Fix the root cause, not just symptoms
   • Add defensive programming if needed
   • Consider edge cases
   • Keep fix minimal and focused, follow KISS

7. Verify Resolution

   • Confirm original issue is fixed
   • Check for regression
   • Test related functionality
   • Add test to prevent recurrence

8. Document Findings
