Matt Pocock(@mattpocockuk):Everyone always confuses my skills with spec-driven-development. It really annoys me. The specs my skills create are intended to be deleted immediately - not kept around, or treated as source code. Birgitta Boeckeler calls this 'spec-first' development, but still groups this under the SDD umbrella (link below). I disagree - I think it needs its own term. The specs aren't that important. They're just a projection of the decisions made during grilling. GDD? Grill-driven-development. IDK
