Guizang releases web PPT skill guizang-ppt-skill: dual visual systems plus presenter mode

The skill ships two visual systems: Style A electronic-magazine style with 10 layouts and 5 e-ink themes, and Style B Swiss International style with 22 named layouts and 4 anchor colors. Body pages must be chosen from S01 to S22, with no custom hex values or ad-hoc page structures allowed. Deliverables are single-file HTML, no build or server needed—just open in a browser. Presenter mode uses dual windows for audience screen, next-slide 16:9 preview, speaker notes, timed rehearsal, auto-advance, laser pointer, and drawing, all running locally with no cloud relay or phone remote. For teams writing decks in Codex, the skill can call GPT-Image 2.0 / GPT-M 2.0 to generate documentary photos, infographics, flowcharts, and UI mockups, inserting them via template-reserved data-image-slot and ratios like 21:9 and 16:10; images must have no footer, page number, or title. For quality control it provides validate-swiss-deck.mjs and validate-presenter-mode.mjs scripts that use Playwright to quantify rendered overflow, bottom whitespace, and title spacing, plus a P0-to-P3 graded checklist. Note that the skill is not suited to large table datasets, training courseware, or multi-user collaborative editing, and the author states HTML-to-PPTX is not the current main flow. Install with a one-line npx skills add command, or send the install instructions to a shell-capable Agent to run git clone.
