principles calculations on commercial personal computers is a monumental step for the quantum chemistry community. Therefore, with great power comes great responsibility. Now, more than ever, we strongly highlight the importance of strict, rigorous protocols for investigating defects formation mechanisms, given the convenience of having publicly available computational tools for materials study and chemical research. The choice between finding the correct methodological compromise between computational speed and accuracy is a predicament that has been plaguing us scientists for years, and will continue to do so for the foreseeable future. A commonly disregarded aspect of the choice to make is that doing it "quick" actually makes it "cheap", i.e., regarding its ground-state configurations, image-charge correction scheme, and the chemical potential range. This is an often-neglected issue in the materials science and catalysis modelling community, which in our experience, can result in major deviation in structural and energetic errors than by the selection of functional approximations. Several ongoing initiatives, including openaccess automated workflow for defects calculations and publicly available databases, have been attempted to effectively mitigate such errors; however, we believed that more efforts are needed to standardize and automate defects calculations while also raising the awareness on proper defects modelling of researchers from fields outside of the catalysis community. We are hopeful that the protocols contributed will aid the efforts in resolving the big problem in surface catalysis modelling.
