Guizang PPT Skill · Web Decks / Images / Covers

An agent skill for Claude Code, Codex, and similar coding-agent environments. It generates single-file HTML horizontal-swipe decks, deck visuals, and social cover pages.

It ships with two visual systems:

Style A: editorial magazine × electronic ink. Picture Monocle with code stitched in. Best for narrative talks, opinions, salons, and personal voice.
Style B: Swiss International Typographic Style. Grid-first, one high-saturation anchor color, sharp rectangles, hairline rules, and extreme type contrast. Best for facts, products, analysis, and frameworks.

Distilled by Guizang from offline talks like "One-Person Company: Organizations Folded by AI" and "A New Way of Working." Every pitfall hit during those decks is logged in checklist.md. Sponsor and supporter details are listed in SPONSORS.md.

What you get

🖋 Two visual systems: editorial storytelling for Style A, factual Swiss structure for Style B
📐 Horizontal swipe navigation: ← → arrows / scroll wheel / touch swipe / bottom dots / ESC for index
🧩 Style A 10 layouts: cover, divider, big numbers, image/text, image grid, pipeline, comparison, and more
🧱 Style B 22 locked layouts: Cover, Statement, KPI Tower, Loop Diagram, Duo Compare, Image Hero, Closing Manifesto, and more
🎨 Curated theme presets: 5 electronic-ink themes for Style A, 4 Swiss anchor-color themes for Style B
🖼 Optional Codex image flow: generate documentary photos, infographics, flow diagrams, system maps, and UI scenes with GPT-Image 2.0 / GPT-M 2.0, then insert them at template-safe ratios
📰 Social covers: generate 21:9 WeChat cover images, 1:1 share cards, 3:4 Xiaohongshu covers, video thumbnails, and related variants
📴 Low-power static mode: press B to turn WebGL / canvas animation into static visuals
📄 Single HTML file — no build, no server, open directly in the browser

Fits / Doesn't fit

✅ Fits: offline talks, industry keynotes, private salons, AI product launches, demo day, presentations with strong personal voice

❌ Doesn't fit: data-heavy tables, training decks (density too low), multi-user collaborative editing (static HTML)

Common use cases

Task	Recommended flow
Long article to talk deck	Extract the core argument, then build a 6-10 slide rhythm
Framework / product analysis	Use Style B Swiss with locked layouts and 21:9 hero visuals
Personal talk / opinion piece	Use Style A editorial magazine for stronger narrative rhythm
Deck visuals	In Codex, generate photos, infographics, flow diagrams, system maps, or UI scenes
Social covers	Generate 21:9 main covers, 1:1 share cards, 3:4 vertical covers, and video thumbnails from the same idea
Screenshot normalization	Redesign raw screenshots into template-safe ratios before inserting them into slides

Why HTML decks

Agent-native editing: HTML / CSS is plain text, so agents can read, edit, and validate it directly.
Higher visual density than Markdown: precise layout, positioning, motion, interactivity, and cover formats.
Lightweight delivery: one HTML file can be opened, presented, sent, screenshotted, or recorded.
Better quality gates: the Swiss validator can catch layout drift, unsafe image placement, centered body titles, and SVG text traps.
One visual system across outputs: decks, generated visuals, covers, and screenshot redesigns can share the same style rules.

Platform support

Platform	Status	Notes
Claude Code	Supported	Native Skill workflow for creating and iterating HTML decks
Codex	Supported	Good for deck generation, image generation, and browser-based visual QA
Cursor / other local agents	Works	Requires filesystem access and shell execution
WorkBuddy	In adaptation	Marketplace-ready version is being prepared separately
Plain chatbot	Not recommended	Without filesystem and browser preview, full deck generation is hard to stabilize

Install

Option 1: One-line install (recommended)

npx skills add https://github.com/op7418/guizang-ppt-skill --skill guizang-ppt-skill

Option 2: Paste this to an AI

Install the guizang-ppt-skill Claude Code skill for me. Steps:

Make sure ~/.claude/skills/ exists (create if not)

Run git clone https://github.com/op7418/guizang-ppt-skill.git ~/.claude/skills/guizang-ppt-skill

Verify: ls ~/.claude/skills/guizang-ppt-skill/ should show SKILL.md, assets/, references/

Tell me when done. Later, saying things like "make me a magazine-style deck" will trigger this skill.

Paste the block above into Claude Code / Cursor / any AI agent with shell access and it handles the install.

Option 3: Manual CLI

git clone https://github.com/op7418/guizang-ppt-skill.git ~/.claude/skills/guizang-ppt-skill

How to trigger it

Once installed, Claude Code auto-detects the skill. Trigger phrases:

"Make me a magazine-style deck"
"Make me a Swiss-style deck"
"Generate a horizontal swipe deck"
"Editorial magazine style presentation"
"Electronic ink slides for my talk"
"Create a 21:9 WeChat cover from this article"
"Create a 1:1 share card from this deck"

Workflow

The skill is a structured workflow; the agent walks you through each step:

Choose style — Style A editorial magazine, or Style B Swiss International
Clarify intent — 7-question checklist: style, audience, duration, source material, images/screenshots, theme, hard constraints
Copy template — Style A uses assets/template.html; Style B uses assets/template-swiss.html
Fill content — create a rhythm plan, then choose and adapt the matching layout skeletons
Optional image generation — in Codex, ask whether to use GPT-Image 2.0 / GPT-M 2.0 images, then insert them at page-appropriate ratios
Self-check — match against references/checklist.md; P0 issues must all pass; Swiss decks must also pass the layout validator
Preview — open the HTML in a browser
Iterate — use inline styles to tune font size, height, spacing

Full spec in SKILL.md.

Style B Swiss

The Swiss theme is a strict layout system, not just a CSS skin.

22 named layouts: body slides must use S01 to S22; do not invent new structures
4 anchor colors: International Klein Blue, lemon yellow, lemon green, safety orange
Grid lock: 16-column grid, sharp rectangles, 1px hairlines, no shadows, no gradients, no rounded cards
Chinese title scaling: all-Chinese headlines should be one step smaller to preserve space for content and images
Image/text bottom alignment: text and image blocks should align at the bottom in left/right image layouts, while staying clear of pagination controls
Image slots: images must sit in template-defined data-image-slot regions, often generated at 21:9 or 16:10
Hard validation: the validator catches centered body titles, experimental layouts, visible SVG text, and images placed outside slots

Swiss validation:

node scripts/validate-swiss-deck.mjs path/to/index.html

Codex Image Flow

In Codex, after the first deck draft is ready, the agent can ask whether the user wants generated visuals. Once confirmed, choose an image type or style. Common types include:

Documentary photos: Fuji / Leica-like real-world scenes that add human texture
Infographics / flow diagrams / comparison charts / system maps: for concepts that cannot be explained well with photos
Screenshot framing / screenshot redesigns: preserve raw screenshots with bundled background assets and a CleanShot X-style canvas first; use UI scene generation only when the screenshot needs reconstruction
Data posters / charts: turn key numbers into insert-ready visual assets
Multi-image compositions: useful for ultra-wide slots where three unrelated 16:9 images would break the grid

Generated images must follow four core rules:

Treat the image as an embedded asset, not a standalone slide: no footer, page bottom, title, page number, corner mark, signature, or decorative border
Match the deck language: Chinese decks use Chinese labels inside infographics, English decks use English labels
Match the slot ratio before generation: 21:9 for many Swiss hero slots, 16:9 / 16:10 for common main visuals, 16:10 for UI scenes, fixed equal heights for image grids
When a raw screenshot must stay faithful, read references/screenshot-framing.md first and use bundled assets/screenshot-backgrounds/ backgrounds plus programmatic scaling, padding, and alignment instead of redrawing the screenshot by default

Image prompts live in references/image-prompts.md. Screenshot framing lives in references/screenshot-framing.md.

Cover Generation

The skill can also turn an article or deck idea into platform covers:

WeChat main cover: 21:9, headline-first, with one visual anchor
WeChat share card: 1:1, visually paired with the 21:9 cover
Xiaohongshu cover / carousel: 3:4, large title, consistent type scale across a batch
Video thumbnail: 16:9, title + subtitle + one focal visual

The same rule applies: use a few strong keywords, keep the title as the visual center, and do not fill the canvas with body copy.

Example prompts

Copy any of these prompts into your agent, then attach your article, Markdown file, or image assets:

Create an 8-slide Swiss-style deck from this article, with 3 generated visuals matched to the template image slots.

Turn this product analysis document into an editorial magazine-style deck with a strong narrative rhythm.

From this deck's core idea, create two covers: a 21:9 main cover and a visually paired 1:1 share card.

Redesign these product screenshots into consistent 16:10 slide visuals. Preserve key UI information; do not add slide titles or footers inside the images.

Theme presets

Pick from references/themes.md. Custom hex values are not allowed — protecting the aesthetic matters more than freedom of choice.

Style A Editorial Themes

Preview	Theme	Core colors and best for
	🖋 Ink Classic	`#0a0a0b` / `#f1efea`. General default, commercial launches, when in doubt.
	🌊 Indigo Porcelain	`#0a1f3d` / `#f1f3f5`. Tech, research, AI, technical keynotes.
	🌿 Forest Ink	`#1a2e1f` / `#f5f1e8`. Nature, sustainability, culture, non-fiction.
	🍂 Kraft Paper	`#2a1e13` / `#eedfc7`. Nostalgic, humanist, literary, indie zines.
	🌙 Dune	`#1f1a14` / `#f0e6d2`. Art, design, creative, fashion, gallery-like decks.

Switching themes only requires replacing the 6 variables at the top of template.html's :root{} block — all other CSS flows through var(--...).

Style B Swiss Themes

Pick from references/themes-swiss.md. Custom hex values are not allowed here either.

Preview	Theme	Anchor color and best for
	🔵 International Klein Blue	`#002FA7`. Default, commercial launches, AI products, frameworks.
	🟡 Lemon Yellow	`#FFD500`. Youth, sports, retail, consumer goods, Y2K retro.
	🟢 Lemon Green	`#C5E803`. Ecology, sustainability, health, Gen Z brands.
	🟠 Safety Orange	`#FF6B35`. Alerts, news, industrial topics, sports, energetic themes.

If the user asks for a Swiss-style deck without specifying color, default to International Klein Blue.

Core design principles

Restraint over flash — WebGL backgrounds only bleed through on hero pages
Structure over decoration — information hierarchy via type size + typeface + grid whitespace, not shadows or floating cards
Images are first-class citizens — align them with the body content area, keep ratios stable, crop only from the bottom, and preserve top/sides
Generated visuals are assets — keep only the core photo / chart / UI; do not render slide titles, footers, or corner marks inside the image
Rhythm lives on hero pages — hero / non-hero alternation keeps the eye from fatiguing
Dynamic effects must be optional — B toggles static mode so animation never becomes a reading burden
Terms stay consistent — Skills is Skills; no mix-and-match translations
Swiss layouts stay locked — Style B should restore and reuse the original 22-page layout system instead of inventing unrelated pages

Improve screenshot redesign and infographic generation workflows
Prepare marketplace-specific variants such as WorkBuddy
Add more curated theme packs while keeping custom colors restricted

FAQ

Can it export to PPTX? The main output is HTML. You can present it in a browser, screenshot it, or record it. PPTX conversion can be done as a separate workflow, but it is not the core path today.

Why are custom colors not allowed? The skill is designed for stable visual output. Arbitrary colors often break the system, so decks must use curated presets.

Can I add my own layout? Yes. Style A layouts can be extended in references/layouts.md. Style B is stricter: update template-swiss.html, layouts-swiss.md, swiss-layout-lock.md, and the validator together.

Is Codex image generation required? No. Decks work without generated images. The image flow is only used when you need photos, infographics, UI scenes, or covers.

How do I update the skill? Run the install command again, or run git pull inside your local skill directory.

Contributing

Bugs, layout issues, new layout requests — Issues and PRs welcome. Prioritize:

Add new classes to template.html first; don't let layouts.md reference undefined classes
When changing template-swiss.html, update layouts-swiss.md and swiss-layout-lock.md together
When adding Swiss rules, update scripts/validate-swiss-deck.mjs
Log pitfalls into checklist.md at the matching P0 / P1 / P2 / P3 tier
New theme colors go into themes.md with a recommended use case
