```

### Medication Pattern
```regex
(prescription|medication|refill).{0,30}(ready|available|pickup).{0,50}(\d+).{0,20}(of|out of).{0,5}(\d+)
```

### Meeting Pattern
```regex
(meeting|standup|sync).{0,30}(tomorrow|today|(?:\w+day)).{0,20}(\d{1,2}(?::\d{2})?\s*(?:AM|PM)?).{0,50}(in|at)\s+([\w\s]+)
```
