**Purpose**: Professional debugging and issue resolution --- @include shared/universal-constants.yml#Universal_Legend ## Command Execution Execute: immediate. --plan→show plan first Legend: Generated based on symbols used in command Purpose: "[Action][Subject] in $ARGUMENTS" Systematically debug and resolve issues in $ARGUMENTS using root cause analysis and evidence-based solutions. @include shared/flag-inheritance.yml#Universal_Always Examples: - `/troubleshoot "app crashes on startup"` - Debug crash - `/troubleshoot --performance "slow API"` - Performance issues - `/troubleshoot --interactive "login fails"` - Guided debugging ## Command-Specific Flags --performance: "Focus on performance bottlenecks" --memory: "Memory leak detection and analysis" --network: "Network-related debugging" --interactive: "Step-by-step guided troubleshooting" --trace: "Enable detailed execution tracing" --bisect: "Git bisect to find breaking commit" ## Troubleshooting Approach **1. Reproduce:** Isolate minimal reproduction | Document steps | Verify consistency | Capture full context **2. Gather Evidence:** Error messages & stack traces | Logs & metrics | System state | Recent changes | Environment differences **3. Form Hypotheses:** Most likely causes | Alternative explanations | Test predictions | Rule out possibilities **4. Test & Verify:** Targeted experiments | Change one variable | Document results | Confirm root cause **5. Fix & Prevent:** Implement solution | Add tests | Document fix | Prevent recurrence ## Common Issue Categories **Performance:** Slow queries | Memory leaks | CPU bottlenecks | Network latency | Inefficient algorithms **Crashes/Errors:** Null references | Type mismatches | Race conditions | Memory corruption | Stack overflow **Integration:** API failures | Authentication issues | Version conflicts | Configuration problems | Network timeouts **Data Issues:** Corruption | Inconsistency | Migration failures | Encoding problems | Concurrency conflicts @include shared/quality-patterns.yml#Root_Cause_Analysis ## Deliverables **Root Cause Report:** Issue description | Evidence collected | Analysis process | Root cause identified | Fix implemented **Fix Documentation:** What was broken | Why it broke | How it was fixed | Prevention measures | Test cases added **Knowledge Base:** Problem→Solution mapping | Troubleshooting guides | Common patterns | Prevention checklist @include shared/universal-constants.yml#Standard_Messages_Templates
