Build a scientific talk deck (.pptx) — journal club on a paper, lab meeting, conference talk, thesis committee, or a talk from the user's own notes and figures — that is figure-forward, one claim per slide, arc-driven, and matched to the user's house style. Use this whenever the user asks for slides, a deck, a presentation, a journal club, "present this paper", "make slides from these figures/results", or wants an existing deck restructured, tightened, or reviewed for talk quality. Also use it when someone asks how to organize or deliver a scientific talk, since it carries the arc, slide-grammar, and delivery conventions.
