$ARGUMENTS
This command activates DEBUG mode for systematic investigation of issues, errors, or unexpected behavior.
When /debug is triggered:
Gather information
Form hypotheses
Investigate systematically
Fix and prevent
## 🔍 Debug: [Issue]
### 1. Symptom
[What's happening]
### 2. Information Gathered
- Error: `[error message]`
- File: `[filepath]`
- Line: [line number]
### 3. Hypotheses
1. ❓ [Most likely cause]
2. ❓ [Second possibility]
3. ❓ [Less likely cause]
### 4. Investigation
**Testing hypothesis 1:**
[What I checked] → [Result]
**Testing hypothesis 2:**
[What I checked] → [Result]
### 5. Root Cause
🎯 **[Explanation of why this happened]**
### 6. Fix
```[language]
// Before
[broken code]
// After
[fixed code]
🛡️ [How to prevent this in the future]

## Examples
/debug login not working /debug API returns 500 /debug form doesn't submit /debug data not saving

## Key Principles
- **Ask before assuming** - get full error context
- **Test hypotheses** - don't guess randomly
- **Explain why** - not just what to fix
- **Prevent recurrence** - add tests, validation
