A computer system may provide various resources to users through one or more programming libraries, such as application programming interfaces (APIs), in order to standardize access to such resources through various general-purpose mechanisms. These programming libraries may be operated by other programs, such as task-specific user interfaces, through which a user may utilize the programming library without having to understand its structure and functions. However, in many scenarios, a user may wish to know the manner of invoking a programming library to achieve an invoked behavior, or may wish to reproduce the behavior without having to utilize the user interface. A user may therefore capture an invocation of the programming library, and may generate an instruction set representing the captured invocation that may be studied, copied, modified, subsequently performed, etc.
