## Enhancement Components

### 1. Negative Pattern Detection

```python
Detected Patterns:
├── "I don't have information about X"
├── "I cannot provide details about X"
├── "I'm not sure about X"
└── "Unfortunately, I don't have..."

Extraction:
└── Topic identification (e.g., "previous roles", "job preferences")
```

### 2. Positive Rewriting

```python
Rewrite Strategies:
├── Redirect to available information
│   └── "My profile highlights the key aspects of X..."
│
├── Offer to discuss further
│   └── "I'd be happy to discuss X in more detail..."
│
├── Focus on documented experience
│   └── "What I can share about X is captured in my experience..."
│
└── Suggest connection
    └── "For additional details about X, let's connect directly."
```

### 3. Positive Closings

```python
Closing Types:
├── Interview invitation
│   └── "I'm excited to share more details in an interview."
│
├── Connection offer
│   └── "Let's connect to explore how my background aligns..."
│
├── Discussion invitation
│   └── "I'd be happy to discuss this further in a conversation."
│
├── Reach-out encouragement
│   └── "Feel free to reach out to learn more about my experience."
│
└── Opportunity expression
    └── "I'd welcome the opportunity to elaborate on my experience."
```
