In this video, I break down the six-step framework I use to reverse engineer strong outputs, give each skill one job and one trigger, choose the right freedom level, build verification loops, test cheaper models, and improve the skill after every run. Then I put the process to work by running my X Article skill across Sol, Terra, and Luna and comparing the results with Astra.
