| Debugging command. Activates DEBUG mode for systematic problem investigation. |
/debug - Systematic Problem Investigation
$ARGUMENTS
Purpose
This command activates DEBUG mode for systematic investigation of issues, errors, or unexpected behavior.
Behavior
When /debug is triggered:
-
Gather information
- Error message
- Reproduction steps
- Expected vs actual behavior
- Recent changes
-
Form hypotheses
- List possible causes
- Order by likelihood
-
Investigate systematically
- Test each hypothesis
- Check logs, data flow
- Use elimination method
-
Fix and prevent
- Apply fix
- Explain root cause
- Add prevention measures
Output Format
## 🔍 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]
7. Prevention
🛡️ [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
