Single-file HTML decks, because agents speak CSS better than PPTX

What it does

Guizang PPT Skill is an agent-facing workflow for Claude Code and Codex that generates single-file HTML slide decks. It packages two complete visual systems—an editorial magazine style and a rigid Swiss Internationalist grid—along with prompt libraries for generating matching images and social-media covers. The output is a plain HTML file that opens in any browser, flips horizontally, and can fall back to a static mode if WebGL feels too fancy for your machine.

The interesting bit

The project treats the agent as the user. Instead of asking you to hand-craft CSS, it gives the AI a locked design system—22 named Swiss layouts, 4 anchor colors, and a validation script that rejects off-grid experiments—so the agent does the layout correctly the first time. It also bakes in image-generation rules for Codex, specifying exact aspect ratios like 21:9 and 16:10 so the pictures actually fit the slots.

Key highlights

• Two visual systems: a narrative “electronic ink” magazine style and a factual Swiss-grid style with 22 locked layouts.
• Single-file HTML output runs fully offline in a browser with keyboard, wheel, touch, and index navigation.
• Built-in image prompt rules for GPT-Image 2.0 / GPT-M 2.0, covering photos, diagrams, screenshot reframing, and multi-platform social covers.
• Swiss style includes a validation script (validate-swiss-deck.mjs) that enforces grid compliance, image-slot binding, and typographic rules.
• Low-power static mode disables WebGL and canvas animations when you press B.

Caveats

• Explicitly not built for data-heavy tables, training materials, or multi-user collaboration; the README admits information density is lower than traditional tools and the format is static HTML.
• Requires an agent environment with file-system and shell access; the authors warn that plain chatbots without browser preview struggle to generate complete decks.

Verdict

Worth a look if you regularly prep talks, demo-day pitches, or social covers and would rather delegate slide grunt work to Claude. Skip it if your workflow depends on collaborative editing or dense spreadsheet-style slides.
