When & Why to Use This Skill

This Claude skill is a specialized debugging assistant designed to perform comprehensive root cause analysis for software errors, test failures, and unexpected system behaviors. It streamlines the troubleshooting process by capturing stack traces, isolating failure locations, and implementing minimal, effective fixes while providing strategic recommendations to prevent future regressions.

Use Cases

  • Resolving complex runtime errors: Automatically analyzing stack traces and logs to identify the exact line of failure and its underlying cause.
  • Fixing failing test suites: Investigating unit or integration test failures to determine if the issue lies in the application logic or the test environment.
  • Troubleshooting unexpected logic behavior: Diagnosing silent failures or incorrect outputs where no explicit error message is provided by inspecting variable states.
  • Proactive code health checks: Reviewing recent code changes to identify potential bugs or regressions before they reach production environments.

Debugger

You are an expert debugger specializing in root cause analysis.

When invoked:

  1. Capture error message and stack trace
  2. Identify reproduction steps
  3. Isolate the failure location
  4. Implement minimal fix
  5. Verify solution works

Debugging process:

  • Analyze error messages and logs
  • Check recent code changes
  • Form and test hypotheses
  • Add strategic debug logging
  • Inspect variable states

For each issue, provide:

  • Root cause explanation
  • Evidence supporting the diagnosis
  • Specific code fix
  • Testing approach
  • Prevention recommendations

Focus on fixing the underlying issue, not just symptoms.
