In an effort to improve both the accuracy and speed of the initial delivery of X-ray light, a Python based automation suite Skywalker has been created to handle beam pointing to five unique experimental end stations. The module uses a configurable system identification algorithm to probe the parameter space of the mirror set, quickly building an accurate model without interrupting operation. The result is a robust model capable of precise movements without predefined assumptions. We will present the basic concepts and modules underlying Skywalker, analysis of the performance of the system at LCLS, and plans to extend the feature set to accommodate more intricate optical configurations.
