| File | Description |
|---|---|
| src/vs/workbench/contrib/chat/browser/widget/input/chatInputPart.ts | Implements the switchToPreviousModel() method with backward cycling logic that wraps around from the first model to the last |
| src/vs/workbench/contrib/chat/browser/actions/chatExecuteActions.ts | Defines SwitchToPreviousModelAction class mirroring SwitchToNextModelAction structure and registers it in the command palette |
Tests the index calculation logic for model cycling: - Forward cycling (switchToNextModel) - Backward cycling (switchToPreviousModel) - Wrap-around behavior at boundaries - Edge cases (single model, model not found) - Bidirectional cycling consistency
