Guizang PPT Skill

Guizang PPT Skill is an open-source skill for Claude Code, Codex and similar file-capable AI agents, published by op7418 (歸藏). It generates single-file HTML horizontal-swipe presentations, slide illustrations and multi-platform covers, and ships with a built-in rehearsal and presenter mode. Version v1.1.0 (published 2026-05-15) added the Swiss style.

What It Is

The skill is a structured workflow made up of a SKILL.md file, HTML templates, reference documents and validation scripts. An agent with shell and file access follows it to turn an article, Markdown file or outline into a browser-openable HTML deck. Two visual systems are included: Style A (electronic magazine × e-ink) for narrative and personal talks, and Style B (Swiss International) for facts, products and analysis. The README says it is not suited to large data tables, training courseware or multi-person collaborative editing.

How the Workflow Runs

The agent picks a style, asks a short set of clarifying questions (audience, duration, materials, image needs, theme color, hard constraints), copies the matching template and fills in content. It can then generate speaker notes and planned timings from the outline. It checks the result against a checklist, and runs validators for Swiss layouts and presenter mode. The output opens directly in a browser, with no build step or server.

Styles, Themes and Layouts

Style A offers 10 layouts and 5 preset themes. Style B offers 22 locked layouts (S01–S22) and 4 anchor colors: Klein blue, lemon yellow, lemon green and safety orange. Custom hex colors are intentionally not allowed. Style B's validator checks layout, image slots and title alignment, and can use Playwright for rendered-overflow measurements when available.

Images and Covers

In Codex, the skill can optionally generate illustrations with GPT-Image 2.0 / GPT-M 2.0, including documentary photos, infographics, flow diagrams and UI scenes. Screenshots can be reframed onto bundled backgrounds. It also produces covers such as WeChat 21:9 headers, 1:1 share cards, Xiaohongshu 3:4 and landscape video covers.

Presenter Mode

Both templates embed the same local presenter runtime. It provides current and next-slide previews, a synced audience window, structured notes, timers, rehearsal recording, optional auto-advance, a laser pointer, annotation, black/white/freeze screens and reconnect handling. It runs entirely in the local browser and does not provide live captions, phone remote control or AI rehearsal scoring.

Setup Path

Install with npx skills add or clone the repository into ~/.claude/skills. The README states that the core deliverable is HTML; PPTX export is not the main flow.
