pakco.html is a local-first visual taste menu for AI-generated decks. It helps users stop describing taste from scratch: browse visible styles, copy an executable prompt, and let Claude Code / Codex / Hermes generate the deck with stable visual constraints.

The underlying skill still authors professional HTML presentations as static files, with themes, full-deck taste cards, layouts, animations, and prompts. One theme file = one look. One layout file = one page type. One animation class = one entry effect. All pages share a token-based design system in assets/base.css.

Install

Codex

Ask Codex to install the GitHub skill from the repo root:

Install this skill from GitHub: https://github.com/pakco77/pakco-html
Use the repo root as the skill path and install it as pakco-html.

Terminal fallback:

curl -fsSL https://raw.githubusercontent.com/pakco77/pakco-html/refs/heads/main/scripts/install-codex.sh | bash

Restart Codex after installation so it reloads ~/.codex/skills/pakco-html.

Claude Code / AgentSkill CLI

npx skills add https://github.com/pakco77/pakco-html

Other AgentSkill agents

For supported agents, use the skills CLI agent target:

npx skills add https://github.com/pakco77/pakco-html --agent kimi-code-cli
npx skills add https://github.com/pakco77/pakco-html --agent qwen-code
npx skills add https://github.com/pakco77/pakco-html --agent gemini-cli

For any agent that reads a local SKILL.md folder, use the generic installer:

curl -fsSL https://raw.githubusercontent.com/pakco77/pakco-html/refs/heads/main/scripts/install-agent.sh | bash -s -- workbuddy
curl -fsSL https://raw.githubusercontent.com/pakco77/pakco-html/refs/heads/main/scripts/install-agent.sh | bash -s -- ~/.some-agent/skills/pakco-html

No build. Pure static HTML/CSS/JS with only CDN webfonts.

Opening the style picker

When the user asks to open/browse the style menu (e.g. "html来", "打开风格菜单", "打开 pakco-html", "打开html风格", "看看有什么风格", "open the picker"), start a local server and open the picker in a browser:

cd ~/.codex/skills/pakco-html && python3 -m http.server 8000 &
# then open: http://localhost:8000/templates/style-picker.html

If you installed with Claude Code / AgentSkill CLI, use ~/.claude/skills/pakco-html instead.

The picker shows 60+ live previews across 4 tabs (Skins / Templates / UI Taste / Social Cards). The user clicks a card to copy the prompt, then pastes it back to you.

When to use

Use when the user asks for any kind of slide-based output or wants to turn text/notes into a presentable deck. Prefer this over building from scratch.

🎤 Presenter Mode (演讲者模式 + 逐字稿)

If the user mentions any of: 演讲 / 分享 / 讲稿 / 逐字稿 / speaker notes / presenter view / 演讲者视图 / 提词器, or says things like "我要去给团队讲 xxx", "要做一场技术分享", "怕讲不流畅", "想要一份带逐字稿的 PPT" — use the presenter-mode-reveal full-deck template and write 150–300 words of 逐字稿 in each slide's <aside class="notes">.

See references/presenter-mode.md for the full authoring guide including the 3 rules of speaker script writing:

不是讲稿，是提示信号 — 加粗核心词 + 过渡句独立成段
每页 150–300 字 — 2–3 分钟/页的节奏
用口语，不用书面语 — "因此"→"所以"，"该方案"→"这个方案"

All full-deck templates support the S key presenter mode (it's built into runtime.js). S opens a new popup window with 4 magnetic cards:

🔵 CURRENT — pixel-perfect iframe preview of the current slide
🟣 NEXT — pixel-perfect iframe preview of the next slide
🟠 SPEAKER SCRIPT — large-font 逐字稿 (scrollable)
🟢 TIMER — elapsed time + slide counter + prev/next/reset buttons

Each card is draggable by its header and resizable by the bottom-right corner handle. Card positions/sizes persist to localStorage per deck. A "Reset layout" button restores the default arrangement.

Why the previews are pixel-perfect: each preview is an <iframe> that loads the actual deck HTML with a ?preview=N query param; runtime.js detects this and renders only slide N with no chrome. So the preview uses the same CSS, theme, fonts, and viewport as the audience view — colors and layout are guaranteed identical.

Smooth navigation: on slide change, the presenter window sends postMessage({type:'preview-goto', idx:N}) to each iframe. The iframe just toggles .is-active between slides — no reload, no flicker. The two windows also stay in sync via BroadcastChannel.

Only presenter-mode-reveal is designed from the ground up around the feature with proper example 逐字稿 on every slide.

Keyboard in presenter window: ← → navigate (syncs audience) · R reset timer · Esc close popup. Keyboard in audience window: S open presenter · T cycle theme · ← → navigate (syncs presenter) · F fullscreen · O overview.

📱 网页模式（Webpage Mode）

If the user says any of: 网页 / 网页版 / 网页形态 / 做个网页 / 生成网页 / web page / webpage / 长页面 / 上下滑 / 手机看的 / 发链接给别人看, or the content is meant for 阅读、传播、存档 rather than live presentation — use the webpage template instead of a deck.

Webpage mode produces a vertically scrolling HTML page with no slide boundaries. Key differences from deck:

	Deck	Webpage
交互	键盘/手势翻页	浏览器原生滚动
布局	全屏 16:9 slide	720px 居中自适应
JS	需要 runtime.js	不需要
body class	(none)	`webpage`
结构	`.deck > .slide`	`.page > section`
适合	演讲、分享会、Keynote	阅读、传播、发链接

How to scaffold:

<body class="webpage">
<div class="page">
  <section class="hero">...</section>
  <div class="section-break"></div>
  <section>...</section>
  ...
  <div class="page-footer">...</div>
</div>
</body>

Starter template: templates/webpage.html. Copy it to start a new webpage. All design tokens (themes, .card, .grid, .pill, .gradient-text, etc.) work in both modes. Do NOT include runtime.js in webpage mode — it's not needed.

Before you author anything — ALWAYS ask or recommend

Do not start writing slides until you understand three things. Either ask the user directly, or — if they already handed you rich content — propose a tasteful default and confirm.

Content & audience. What's the deck about, how many slides, who's watching (engineers / execs / 小红书读者 / 学生 / VC)?
Style / theme. Which of the 36 themes fits? If unsure, recommend 2-3 candidates based on tone:
- Business / investor pitch → pitch-deck-vc, corporate-clean, swiss-grid
- Tech sharing / engineering → tokyo-night, dracula, catppuccin-mocha, terminal-green, blueprint
- 小红书图文 → xiaohongshu-white, soft-pastel, rainbow-gradient, magazine-bold
- Academic / report → academic-paper, editorial-serif, minimal-white
- Edgy / cyber / launch → cyberpunk-neon, vaporwave, y2k-chrome, neo-brutalism
Starting point. One of the 15 native full-deck templates, 9 Guizang variants, or scratch? Point to the closest templates/full-decks/<name>/ and ask if it fits. If the user's content suggests something obvious (e.g. "我要做产品发布会" → product-launch), propose it confidently instead of asking blindly.

A good opening message looks like:

我可以给你做这份 PPT！先确认三件事：

大致内容 / 页数 / 观众是谁？

风格偏好？我建议从这 3 个主题里选一个：tokyo-night（技术分享默认好看）、xiaohongshu-white（小红书风）、corporate-clean（正式汇报）。

要不要用我现成的 tech-sharing 全 deck 模板打底？

Only after those are clear, scaffold the deck and start writing.

Update (更新)

When the user says "更新 pakco-html", "update pakco-html", "升级", or "拉最新版", run:

bash ~/.codex/skills/pakco-html/scripts/update.sh

For Claude Code installs, run bash ~/.claude/skills/pakco-html/scripts/update.sh.

If scripts/update.sh doesn't exist yet (old install), run the equivalent inline:

TMP=$(mktemp -d) && git clone --depth 1 https://github.com/pakco77/pakco-html.git "$TMP/r" 2>/dev/null && mkdir -p ~/.codex/skills/pakco-html && cp -r "$TMP/r/assets" "$TMP/r/templates" "$TMP/r/references" "$TMP/r/scripts" ~/.codex/skills/pakco-html/ && cp "$TMP/r/SKILL.md" ~/.codex/skills/pakco-html/ && rm -rf "$TMP" && echo "✅ 更新完成"

All existing decks that reference assets/ via relative paths will automatically get the latest features (themes, layouts, mobile support, bug fixes) — no HTML changes needed.

Quick start

Scaffold a new deck. From the repo root:

./scripts/new-deck.sh my-talk
open examples/my-talk/index.html

Pick a theme. Open the deck and press T to cycle. Or hard-code it:
```
<link rel="stylesheet" id="theme-link" href="../assets/themes/aurora.css">
```
Catalog in references/themes.md.
Pick layouts. Copy <section class="slide">...</section> blocks out of files in templates/single-page/ into your deck. Replace the demo data. Catalog in references/layouts.md.
Add animations. Put data-anim="fade-up" (or class="anim-fade-up") on any element. On <ul>/grids, use anim-stagger-list for sequenced reveals. For canvas FX, use <div data-fx="knowledge-graph">...</div> and include <script src="../assets/animations/fx-runtime.js"></script>. Catalog in references/animations.md.
Use a full-deck template. Copy templates/full-decks/<name>/ into examples/my-talk/ as a starting point. Each folder is self-contained with scoped CSS. Catalog in references/full-decks.md and gallery at templates/full-decks-index.html.

Render to PNG.

./scripts/render.sh templates/theme-showcase.html       # one shot
./scripts/render.sh examples/my-talk/index.html 12      # 12 slides

Authoring rules (important)

Always start from a template. Don't author slides from scratch — copy the closest layout from templates/single-page/ first, then replace content.
Use tokens, not literal colors. Every color, radius, shadow should come from CSS variables defined in assets/base.css and overridden by a theme. Good: color: var(--text-1). Bad: color: #111.
Don't invent new layout files. Prefer composing existing ones. Only add a new templates/single-page/*.html if none of the 31 fit.
Respect chrome slots. .deck-header, .deck-footer, .slide-number and the progress bar are provided by assets/base.css + runtime.js.
Keyboard-first. Always include <script src="../assets/runtime.js"></script> so the deck supports ← → / T / A / F / S / O / hash deep-links.
One .slide per logical page. runtime.js makes .slide.is-active visible; all others are hidden.
Supply notes. Wrap speaker notes in <div class="notes">…</div> inside each slide. Press S to open the overlay.
NEVER put presenter-only text on the slide itself. Descriptive text like "这一页展示了……" or "Speaker: 这里可以补充……" or small explanatory captions aimed at the presenter MUST go inside <div class="notes">, NOT as visible <p> / <span> elements on the slide. The .notes class is display:none by default — it only appears in the S overlay. Slides should contain ONLY audience-facing content (titles, bullet points, data, charts, images).

Rendering to PNG

scripts/render.sh wraps headless Chrome at /Applications/Google Chrome.app/Contents/MacOS/Google Chrome. For multi-slide capture, runtime.js exposes #/N deep-links, and render.sh iterates 1..N.

./scripts/render.sh templates/single-page/kpi-grid.html        # single page
./scripts/render.sh examples/demo-deck/index.html 8 out-dir    # 8 slides, custom dir
