version: "1.0.0" name: huashu-slides description: 从内容到成品PPTX的端到端演示文稿制作，含AI插画生成和18种设计风格。当用户提到"做PPT"、"做幻灯片"、"演示文稿"、"Keynote"、"slides"时使用。

AI Presentation Workflow

Create professional presentations: Content → Design → Build → Assembly → Polish.

Step 0: Choose Workflow Settings

At the start of every presentation task, ask the user TWO choices:

0-A. Collaboration Mode

If the user doesn't specify, default to Guided mode.

0-B. Assembly Method

Trade-offs:

If the user doesn't specify, default to Path A (Editable HTML).

Step 1: Content Structuring

Turn raw material into a slide-by-slide outline.

Per slide, define:

• Title — a complete assertion sentence (not a topic word)
• Key points — 3-4 maximum
• Visual type — illustration / chart / diagram / icon / quote
• Path A: Illustration needed? — Yes/No. If yes, one-line description.
• Path B: Visual scene description — one paragraph describing the complete slide visual (layout + imagery + mood).

Assertion-Evidence rule:

语言规则：slide内容一律用中文，仅保留必要的英文术语（人名、品牌名、技术专有名词）。 Section label（如 INSIGHT、TAKEAWAY）可用英文作为设计元素。

✅ Checkpoint 1 (Guided + Collaborative)

Present the outline as a table:

Path A:

| # | Title (assertion) | Key Points | Visual Type | Illustration? |
|---|-------------------|------------|-------------|---------------|
| 1 | Cover: ... | — | Decorative | Yes: ... |
| 2 | ... | 1. ... 2. ... | Chart | No |
| 3 | ... | 1. ... 2. ... | Illustration | Yes: ... |

Path B:

| # | Title (assertion) | Key Points | Visual Scene Description |
|---|-------------------|------------|--------------------------|
| 1 | Cover: ... | — | Dark gradient bg, large title centered, abstract network nodes |
| 2 | ... | 1. ... 2. ... | Split layout: text left, bar chart right, clean white bg |
| 3 | ... | 1. ... 2. ... | Full illustration: person at crossroads with floating clocks |

Ask the user:

• Approve / adjust slide count
• Path A: Approve / adjust which slides get illustrations
• Path B: Approve / adjust visual scene descriptions
• Any content to add or remove

Step 2: Design System

Present 3 design system options for the user to choose from. Each is a complete visual language, not just a color palette.

CRITICAL: A design system is NOT just colors. It defines visual philosophy, typography ratios, composition rules, and emotional intent. This is the difference between "boring PPT" and "magazine-quality deck."

🗣️ Style Discussion (Optional, if user wants to explore)

If the user says things like:

• "我想要XX风格"（田中一光、瑞士国际主义、包豪斯、蒙德里安...）
• "我不确定想要什么风格"
• "能给我看看不同风格的例子吗"

Then consult the design movements reference: references/design-movements.md — 设计运动与风格参考库

This file maps classic design movements (Neo-Brutalism, Swiss Style, Bauhaus, etc.) to our AI-ready style presets. Use it to:

1. Translate user's aesthetic language into actionable prompts
2. Build shared vocabulary ("这个方向偏田中一光" vs "那个偏构成主义")
3. Reference when designing new custom styles from scratch

After discussing movements, proceed to recommend 3 concrete presets below.

Design System Presets

⚠️ CRITICAL INSIGHT: 插画/漫画类风格的AI生成效果远好于「专业极简」类风格。 漫画/插画风格有明确的视觉语言（线条、角色、色块），AI可以充分发挥；极简风格（暗色底+发光文字+大量留白）缺乏视觉元素，生成出来「空」且「平」。

Pick 3 that match the topic/mood. Use the topic recommendation table below, then present each with its full description.

按主题自动推荐（优先从此表选）：

更深入的风格细节：参考 design-philosophy skill 的 references/design-styles.md，包含20种设计哲学的完整提示词DNA

🎨 Custom Character Style (User-Defined)

Users may want to reference specific cartoon/anime aesthetics. When a user says "do it in Doraemon style" or "like Studio Ghibli", treat this as a style reference, not a request to draw copyrighted characters. Build a custom Design System by extracting the visual DNA of that style.

How to convert a character reference into a Design System:

Template for custom style:

[User Style]: "[reference name]"
→ Shape language: [round/angular/geometric/organic]
→ Line quality: [thin uniform / thick varied / sketchy / brushwork]
→ Color palette: [specific colors extracted from that aesthetic]
→ Character style: [proportions, expressiveness level]
→ Background treatment: [detailed/minimal/abstract]
→ Emotional tone: [warm/energetic/philosophical/surreal]

Typography Rules (All Presets)

• Max 2 font families (1 heading + 1 body)
• Heading: bold, personality — ≥36pt (trend: even larger, as graphic surface)
• Body: clean, readable — ≥18pt
• Chinese: system default (PingFang SC / Microsoft YaHei)
• Key principle: Typography is a DESIGN ELEMENT, not just an information container

✅ Checkpoint 2 (Guided + Collaborative)

Ask the user to pick one of the 3 proposed design systems, or describe their own preference. Show the full description including philosophy, visual language, and reference.

Step 3: Build Slides

Step 3-A: HTML + Selective Illustrations (Path A)

Generate AI illustrations for key slides, then create HTML slide files.

Which slides need illustrations? Prioritize:

1. Cover slide — always. Sets the visual tone.
2. Key insight slides — the "aha moment" slides benefit most.
3. Closing slide — optional but impactful.
4. Data-heavy slides — charts/diagrams instead of AI art.

Illustration Generation — use nano-banana-pro skill:

export $(grep GEMINI_API_KEY ~/.claude/.env) && \
uv run ~/.claude/skills/nano-banana-pro/scripts/generate_image.py \
  --prompt "[description]" \
  --filename "[timestamp]-slide-[N]-[name].png" \
  --resolution 2K

Base Style Prompt — define ONE style suffix, append to every illustration:

[Base Style]: flat vector illustration, [palette background color] background,
[accent color] highlight elements, clean minimalist aesthetic,
professional presentation style, no text in image

Per-slide prompt = [specific content] + [Base Style]

Key rules:

• Always include "no text in image" — text will be added as editable elements
• Use descriptive paragraphs, not keyword lists
• Specify hex colors explicitly
• Use "flat vector" / "flat illustration" for consistency

Embedding in HTML slides:

<!-- Side illustration (recommended) -->
<div class="left"><!-- text content --></div>
<div class="right"><img src="illustration.png" style="width: 280pt; height: 280pt;"></div>
 
<!-- Background illustration -->
<body style="background-image: url('illustration.png'); background-size: cover;">

✅ Checkpoint 3-A (Guided: preview 2-3 key illustrations; Collaborative: every one)

Show generated illustrations. Ask: Approve / regenerate / style consistent?

Step 3-B: Full AI Slide Generation (Path B)

Generate EVERY slide as a complete AI image — layout, text, visuals, all in one.

⚠️ THE #1 MISTAKE: Over-constraining the prompt with layout details and visual restrictions. More constraints = LESS creativity and diversity. The AI generates best when given mood + reference + content, NOT specific positions, color ratios, or character restrictions.

The Golden Rule of AI Image Prompts

SHORT prompts > LONG prompts. A 3-sentence prompt describing mood and content produces better results than a 30-line prompt specifying every visual detail. Specifically:

Base Style Prompt — Keep it SHORT

Define a base style once, append to every slide. Keep it under 5 lines. The base style sets the mood; per-slide prompts add the content.

[Base Style]:
VISUAL REFERENCE: [Specific art/design aesthetic in one sentence]
CANVAS: 16:9 aspect ratio, 2048x1152 pixels, high quality rendering.
COLOR SYSTEM: [Describe the mood/feel of colors, not exact ratios]

Example (good — concise):

VISUAL REFERENCE: Charles Schulz Peanuts comic strip — warm, philosophical, charming.
Characters include round-headed kids, a lovable beagle dog, and a small yellow bird.
CANVAS: 16:9 aspect ratio, 2048x1152 pixels, high quality rendering.
COLOR SYSTEM: Warm cream/newspaper tone background, soft muted pastels, warm ink lines.

Anti-pattern (bad — over-specified): Do NOT include typography sizes, color ratios, composition percentages, margin specifications, or visual weight distributions in the base style. These constraints reduce diversity without improving quality.

Per-Slide Prompt Structure

Keep per-slide prompts short and focused. Do NOT repeat base style details or over-specify visual layout.

Create a [style] slide about [topic].
 
[Base Style]
 
DESIGN INTENT: [1 sentence — what the viewer should FEEL]
 
TEXT TO RENDER:
- Title: "[exact text]"
- Body: "[exact text]"
 
[Optional: 1-2 sentences describing mood or scene. Let AI decide composition.]

Example — GOOD vs BAD

BAD (traditional PPT — boring):

Design a professional presentation slide.
Professional presentation slide, 16:9 aspect ratio, 2048x1152 pixels.
Dark navy background, light gray text, gold accent.
Slide type: content. Layout: Title at top-left, two columns below.
Title: "看涨期权收益结构"
Body: "行权价: 100元, 权利金: 10元"
Visual: a line chart showing call option payoff

→ Result: Generic PPT that could come from any template

GOOD (magazine-level — stunning):

Create a slide that feels like a Bloomberg terminal data visualization
brought to life as editorial art.
 
VISUAL REFERENCE: Bloomberg Businessweek data feature meets cinematic lighting.
CANVAS: 16:9, 2048x1152, sharp rendering.
COLOR SYSTEM: Deep black (#0A0A0A) background 75%, white text 15%,
gold (#BF9A4A) accent 10%. The gold represents profit — it should GLOW.
TYPOGRAPHY: The number "110" rendered at 100pt as the dominant visual anchor
(the break-even point IS the story). Supporting text at 14pt, muted gray.
 
DESIGN INTENT: The viewer should instantly FEEL the asymmetry of options —
limited downside, unlimited upside. The visual must make this visceral,
not just informational.
 
TEXT TO RENDER:
- Hero metric: "110" (giant, gold, the break-even price)
- Title: "盈亏平衡点" (medium, white, above the number)
- Left data: "行权价 100" "权利金 10" (small, gray, understated)
- Insight: "亏损有底 盈利无限" (accent color, bottom)
 
VISUAL NARRATIVE: A single golden curve emerges from the left side of the slide,
flat and muted in gray at -10 (the maximum loss), then suddenly bending upward
at the strike price, transitioning from gray to brilliant gold as it rises
into the profit zone. The curve should feel like a ray of light breaking
through darkness. The profitable area above zero glows with warm gold
atmospheric lighting, like sunrise. The chart has NO grid lines, NO axes labels
cluttering the visual — just the pure, dramatic curve and the giant "110"
floating at the inflection point.

→ Result: An editorial data visualization that tells a story

Key Rules for Path B Prompts

Prompt Quality Checklist (verify before every generation):

1. Visual Reference — Does the prompt name a specific art style or publication? (NOT just "professional" or "modern")
2. Mood, not Layout — Does the prompt describe what the viewer should FEEL, not where elements should be PLACED?
3. Text Content — Are all texts to render listed clearly and accurately?
4. Short Enough — Is the prompt concise? Long prompts with detailed specs REDUCE diversity. Remove anything the AI can decide on its own.
5. NO Micro-Management — No hex color ratios, no typography sizes, no composition percentages, no character pose instructions.

Technical Rules:

• Always specify resolution: 2048x1152 (2K, 16:9) for crisp text
• Include ALL text verbatim — AI must render exact words
• 中文优先: slide上的文字一律用中文，仅保留必要英文术语
• Chinese text tip: Keep titles short (≤8 characters) for best rendering
• Use descriptive paragraphs, not keyword lists
• Generate in parallel: Run 3-5 slide generations concurrently for speed
• Consistency: The Base Style is applied to EVERY slide. It's a system, not a suggestion

Generation command (same tool, but full-slide prompts):

export $(grep GEMINI_API_KEY ~/.claude/.env) && \
uv run ~/.claude/skills/nano-banana-pro/scripts/generate_image.py \
  --prompt "[full slide prompt]" \
  --filename "slide-[NN]-[name].png" \
  --resolution 2K

Quality check after generation:

1. Text accuracy — verify all Chinese/English text rendered correctly
2. Layout — elements positioned as described
3. Style consistency — colors and design language match across slides
4. If a slide has text errors → regenerate with adjusted prompt (simplify text or shorten)

✅ Checkpoint 3-B (Guided: preview all slides as a set; Collaborative: approve each)

Show ALL generated slide images to the user. Ask:

• Text readable and accurate?
• Visual style consistent across slides?
• Any slides to regenerate?

Step 4: PPTX Assembly

4-A: html2pptx Workflow (Path A)

Create HTML files per slide, convert with html2pptx.js:

const pptxgen = require('pptxgenjs');
const html2pptx = require(process.env.HOME + '/.agents/skills/pptx/scripts/html2pptx.js');
const pptx = new pptxgen();
pptx.layout = 'LAYOUT_16x9';
await html2pptx('slide1.html', pptx);
await html2pptx('slide2.html', pptx);
await pptx.writeFile({ fileName: 'output.pptx' });

HTML rules (from pptx skill):

• Body dimensions: width: 720pt; height: 405pt (16:9)
• ALL text must be in <p>, <h1>-<h6>, <ul>, <ol> tags
• Backgrounds/borders only on <div> elements
• No CSS gradients — pre-render as PNG with Sharp
• Use web-safe fonts only (Arial, Helvetica, Georgia, etc.)
• Images: <img src="illustration.png" style="width: Xpt; height: Ypt;">

Known issue: Chinese characters in file paths can break image loading. Use symlinks to ASCII paths if needed:

ln -sf "/path/with/中文/" /tmp/ascii-path

4-B: Image Assembly (Path B)

Assemble generated slide images into PPTX using create_slides.py:

uv run ~/.claude/skills/image-to-slides/scripts/create_slides.py \
  slide-01-cover.png slide-02-intro.png slide-03-definition.png ... \
  --layout fullscreen \
  --bg-color 000000 \
  -o output.pptx

Recommended layout for Path B: `fullscreen` — images fill the entire slide since they already contain all layout, text, and visuals.

Step 5: Preview & Polish

Preview

Path A: Screenshot 3-4 key HTML slides with Playwright:

npx playwright screenshot "file:///path/to/slide.html" preview.png \
  --viewport-size=960,540 --wait-for-timeout=1000

Path B: Show the generated slide images directly (they ARE the slides). Use Read tool to display 3-4 key PNGs.

✅ Checkpoint 4 (All modes)

Show preview to the user. The PPTX file is ready — ask:

• Any slides to adjust?
• Ready to open in Keynote/PowerPoint?

Final Polish (in Keynote/PowerPoint)

• Transitions and animations
• Speaker notes
• Brand logo placement
• Path A: Final text adjustments (editable)
• Path B: Text NOT editable — if text errors found, regenerate the slide image

Design Quick Reference

5/5/5 rule: ≤5 words/line, ≤5 bullets/slide, ≤5 text-heavy slides in a row

Cognitive load: One idea per slide. ~1 min per slide. Slides complement speech, never duplicate it.

Visual hierarchy: F/Z-pattern reading flow. Title:body size ≈ 3:1. Every slide should have a visual element.
