Get information about the current workspace.

isWorkspaceHealthy(): Promise<boolean>

Check if the workspace is in a healthy state.

cleanWorkspace()

Clean up the workspace and all tracking data.

getWorkspaceSize(): Promise<{files: number, sizeBytes: number}>

Get workspace size information.

Configuration

getConfig(): OopsConfig

Configuration Options

interface OopsConfig {
  workspace: {
    useTemp: boolean;    // Use temporary directory

  safety: {
    confirmKeep: boolean;   // Confirm before applying changes
    confirmUndo: boolean;   // Confirm before undoing
    autoBackup: boolean;    // Automatic backup creation
  };
  diff: {
    tool: string;    // External diff tool ('auto', 'code', 'vimdiff', etc.)
