13. A non-transitory computer-readable medium storing a computer program that when executed on a computer, performs a method comprising: acquiring a representation of actions of a user performing multiple iterations of a task with a web service; analyzing the acquired actions to determine semantics and a plurality of variables describing the user actions, each variable being an input to the web service that the web service ordinarily requests the user to enter during the multiple iterations of the task, the variables comprising free variables and bound variables, where which of the variables are the free variables and which of the variables are the bound variables is determined automatically without prompting the user, by analyzing differences in the actions of the user across the multiple iterations of the task; representing the semantics and the variables in at least one script file, the at least one script file supporting performance of user interaction with the web service based on the semantics and values provided for the variables, where each bound variable has a constant value over multiple executions of the at least one script file, and each free variable has a value that is changeable over the multiple executions of the at least one script file; and associating the at least one script file with a unique uniform resource locator (URL) address that is selectable to initiate performance of user interaction with the web service, wherein the unique URL address is selectable by different user devices to invoke and execute the user interaction.

The non-transitory computer-readable medium of claim 13 , wherein analyzing further comprises determining potential values of the variables, and wherein representing further comprises representing the potential values in a file.
