powerpoint-skill

Create visually rich PowerPoint (.pptx) presentations from academic papers, research notes, or any content the user wants in slide format. Uses PptxGenJS + LaTeX formula rendering. Always use this skill when the user wants PPT/PPTX output instead of Beamer/LaTeX slides. Trigger on: powerpoint, pptx, PPT, make a ppt, 做PPT, 做幻灯片, make slides (non-LaTeX), prepare a presentation (when context implies PPT), 做个报告, presentation slides, help me prepare a talk (when not Beamer), convert paper to slides (when PPT implied). Even if the user just says "make slides" or "做个演示" without specifying format, trigger this skill and ask whether they want PPT or Beamer — don't silently default to Beamer. Do NOT trigger on: beamer, latex slides, .tex files, tikz — those belong to the beamer skill.
