pptx skillA

pptx is agent-read markdown (skill) from lukaskellerstein/claude-my-marketplace: This skill should be activated when the user asks to make a presentation, slide deck, pitch deck, or anything involving .pptx output. Also triggers when the user says 'make me slides', 'create a deck', 'presentation about X', or mentions PowerPoint. Creates polished PowerPoint (.pptx) presentations using PptxGenJS for all slide generation. Can also edit existing PPTX templates. Activates even for simple 'make a quick 3-slide deck' requests — the skill ensures quality output every time..

Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
