# Code Smell Doctor

Analyze code for the 23 classic code smells and recommend specific refactoring techniques.

## Analysis Workflow

1. Read the target code file(s)
2. Scan for each smell category systematically
3. Report findings with severity (High/Medium/Low), location, explanation, and fix
4. Prioritize by impact on maintainability

## Quick Reference

| Category | Smells |
|----------|--------|
| Bloaters | Long Method, Large Class, Primitive Obsession, Long Parameter List, Data Clumps |
| OO Abusers | Alt Classes w/ Diff Interfaces, Refused Bequest, Switch Statements, Temporary Field |
| Change Preventers | Divergent Change, Parallel Inheritance, Shotgun Surgery |
| Dispensables | Comments, Duplicate Code, Data Class, Dead Code, Lazy Class, Speculative Generality |
| Couplers | Feature Envy, Inappropriate Intimacy, Incomplete Library Class, Message Chains, Middle Man |

## Detection Patterns

For detailed detection heuristics and refactoring techniques, see:
- [references/bloaters.md](references/bloaters.md) - Size-related smells
- [references/oo-abusers.md](references/oo-abusers.md) - OOP misuse patterns
- [references/change-preventers.md](references/change-preventers.md) - Rigidity smells
- [references/dispensables.md](references/dispensables.md) - Unnecessary code
- [references/couplers.md](references/couplers.md) - Coupling issues

## Output Format

For each smell found:

```
### [Smell Name] (Severity: High/Medium/Low)
**Location:** file:line or class/method name
**Problem:** Brief explanation of what's wrong
**Evidence:** Specific code indicators
**Fix:** Recommended refactoring technique(s)
```

## Severity Guidelines

- **High**: Actively impedes development, causes bugs, or makes changes risky
- **Medium**: Makes code harder to understand or modify
- **Low**: Minor issue, fix when touching the code anyway

## Common Detection Heuristics

### Bloaters
- Method >15 lines or >3 levels of nesting → Long Method
- Class >300 lines or >10 fields → Large Class
- Repeated primitive groups (e.g., `startDate`, `endDate`) → Data Clumps
- >4 parameters → Long Parameter List
- Constants like `USER_ADMIN = 1` → Primitive Obsession

### OO Abusers
- `switch` on type codes → Switch Statements
- Subclass overrides parent methods to throw/no-op → Refused Bequest
- Fields only set in certain methods → Temporary Field
- Two classes with same behavior, different names → Alternative Classes

### Change Preventers
- One class changes for unrelated reasons → Divergent Change
- One change touches many classes → Shotgun Surgery
- Creating `FooX` requires creating `BarX` → Parallel Inheritance

### Dispensables
- Comments explaining what code does (not why) → Comments smell
- Copy-pasted code blocks → Duplicate Code
- Class with only getters/setters → Data Class
- Unreachable code, unused vars → Dead Code
- Class doing almost nothing → Lazy Class
- Abstract class with one implementation → Speculative Generality

### Couplers
- Method uses other object's data more than own → Feature Envy
- Classes accessing each other's internals → Inappropriate Intimacy
- Chains like `a.getB().getC().getD()` → Message Chains
- Class only delegates, no real logic → Middle Man
