  - src/workers/payment-processor.ts (async processing)
```

### 3. Inline Completions
Context-aware autocomplete as you type:

```typescript
// Cody knows your project's patterns
function createUser(data: CreateUserInput) {
  // Cody suggests based on your existing code patterns,
  // not generic boilerplate
}
