A method of extending a conversational computing interface comprises obtaining data-flow traces indicating computational steps that occur based on execution of a nonnative skill implemented in a nonnative programming language of the conversational computing interface. A native computer-executable plan is automatically generated. The generated native computer-executable plan represents the data-flow traces in a native programming language of the conversational computing interface. The conversational computing interface is automatically trained based on the native computer-executable plan and a conversational event associated with the native computer-executable plan.
