Magazine Web PPT · Editorial-Style Web Slide Deck Skill

An agent skill for Claude Code, Codex, and similar coding-agent environments. It generates single-file HTML horizontal-swipe decks with an "editorial magazine × electronic ink" aesthetic — picture Monocle with code stitched in.

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.

What you get

• 🖋 Three-tier type system: serif for headlines, sans-serif for body, mono for metadata
• 🌊 WebGL fluid / dispersion backgrounds — visible on hero pages, restrained on body pages
• 📐 Horizontal swipe navigation: ← → arrows / scroll wheel / touch swipe / bottom dots / ESC for index
• 🎨 5 curated theme presets: Ink Classic / Indigo Porcelain / Forest Ink / Kraft Paper / Dune
• 🧩 10 page layouts: cover, act divider, big numbers, lead image + text, image grid, pipeline, hero question, big quote, before/after, image + text mix
• 🖼 Optional Codex image flow: generate documentary photos, infographics, flow diagrams, system maps, and UI scenes with GPT-M 2.0, then insert them at template-safe ratios
• 📄 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)

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:

1. Make sure ~/.claude/skills/ exists (create if not)
2. Run git clone https://github.com/op7418/guizang-ppt-skill.git ~/.claude/skills/guizang-ppt-skill
3. Verify: ls ~/.claude/skills/guizang-ppt-skill/ should show SKILL.md, assets/, references/
4. 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"
• "Generate a horizontal swipe deck"
• "Editorial magazine style presentation"
• "Electronic ink slides for my talk"

Workflow

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

1. Clarify intent — 6-question checklist: audience, duration, source material, images, theme, hard constraints
2. Copy template — assets/template.html → project folder, update <title>, swap theme vars
3. Fill content — pick from 10 layout skeletons, paste, edit copy (with class-name pre-flight + theme rhythm plan)
4. Optional image generation — in Codex, ask whether to use GPT-M 2.0 images, then insert them at page-appropriate ratios
5. Self-check — match against references/checklist.md; P0 issues must all pass
6. Preview — open the HTML in a browser
7. Iterate — use inline styles to tune font size, height, spacing

Full spec in SKILL.md.

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 redesigns / UI scenes: reshape raw screenshots into consistent slide-friendly ratios and visual density

Generated images must follow two 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 slot ratio before generation: 16:9 / 16:10 for main visuals, 16:10 for UI scenes, fixed equal heights for image grids

Theme presets

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

Theme	Best for
🖋 Ink Classic	general default, commercial launches, when in doubt
🌊 Indigo Porcelain	tech / research / AI / technical keynotes
🌿 Forest Ink	nature / sustainability / culture / non-fiction
🍂 Kraft Paper	nostalgic / humanist / literary / indie zines
🌙 Dune	art / design / creative / gallery

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

Core design principles

1. Restraint over flash — WebGL backgrounds only bleed through on hero pages
2. Structure over decoration — information hierarchy via type size + typeface + grid whitespace, not shadows or floating cards
3. Images are first-class citizens — align them with the body content area, keep ratios stable, crop only from the bottom, and preserve top/sides
4. Generated visuals are assets — keep only the core photo / chart / UI; do not render slide titles, footers, or corner marks inside the image
5. Rhythm lives on hero pages — hero / non-hero alternation keeps the eye from fatiguing
6. Terms stay consistent — Skills is Skills; no mix-and-match translations

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
• 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
