DESCRIPTION:Lattice QCD matrix elements of effective weak operators must b
 e combined with Wilson coefficients that are calculated in perturbation th
 eory using dimensional regularization. Doing so requires an intermediate r
 egularization-independent (RI) renormalization scheme. We have recently co
 mpleted a one-loop calculation of the RI to $\\overline{\\text{MS}}$ renor
 malization scheme conversion factors for the $\\Delta S = 1$ four-quark op
 erators entirely by directing an agentic AI system to generate Mathematica
  code. These factors are required for lattice QCD simulations of weak proc
 esses\, such as $K \\rightarrow \\pi\\pi$ decay and the long-distance cont
 ributions to the CP-violating parameter $\\epsilon_K$. In this talk\, we d
 iscuss our supervision strategy and the methods we used to ensure the corr
 ectness of our results. We conclude by discussing an ongoing two-loop calc
 ulation of matching factors required for the bi-local operator products co
 ntributing to $\\epsilon_K$\, and the prospects for using our agentic AI s
 trategy to rapidly complete further calculations.\nhttps://bnl.zoomgov.com
