# Slide Creator Skill

Create zero-dependency, animation-rich HTML presentations that run entirely in the browser. This skill helps non-designers discover their preferred aesthetic through visual exploration ("show, don't tell"), then generates production-quality slide decks.

## Core Philosophy

1. **Zero Dependencies** — Single HTML files with inline CSS/JS. No npm, no build tools.
2. **Show, Don't Tell** — People don't know what they want until they see it. Generate visual previews, not abstract choices.
3. **Distinctive Design** — Avoid generic "AI slop" aesthetics. Every presentation should feel custom-crafted.
4. **Production Quality** — Code should be well-commented, accessible, and performant.
5. **Viewport Fitting (CRITICAL)** — Every slide MUST fit exactly within the viewport. No scrolling within slides, ever. This is non-negotiable.
6. **Plan Before Generate** — For complex decks, use `--plan` to create a PLANNING.md outline first, then `--generate` to produce the HTML. This separates thinking from execution.

---

## Command Flags

Parse the invocation to determine mode:

- **`--plan [prompt]`** — Planning mode. Inspect `resources/`, analyze the prompt, create `PLANNING.md`, present for review. **Do NOT generate HTML.**
- **`--generate [instructions]`** — Generation mode. Read `PLANNING.md` if it exists (skip Phase 1/2 questions), then generate the presentation. If no `PLANNING.md`, run normal Phase 0-3 workflow.
- **`--export pptx [--scale N]`** — Export mode. Convert the generated HTML to PPTX using the script in `scripts/`. Requires Node.js ≥ 18.
- **No flag** — Auto-detect mode (existing Phase 0 behavior).

---

## Planning Mode (`--plan`)

When `--plan` is given:

1. **Check `resources/` folder**
   - Scan for files (markdown, PDF, text, images). If present, read and summarize what was found.
   - If missing or empty, note: "No resources found. Planning from prompt only."

2. **Analyze the prompt**
   - Extract: topic, audience, tone, language, slide count, goals.

3. **Draft the plan**
   - Follow the structure in [references/planning-template.md](references/planning-template.md).
   - For each slide: write the actual key point, supporting bullets, and visual element type.
   - Map content from `resources/` to specific slides.
   - Include visual/layout guidelines — use defaults from [references/design-system.md](references/design-system.md).

4. **Save to `PLANNING.md`** in the working directory.

5. **Present the plan** to the user: slide count, structure, key decisions. Ask for approval.

6. **Stop.** Do NOT generate HTML.

---

## Export Mode (`--export pptx`)

When `--export pptx` is given:

1. **Find the presentation HTML** — Look for `*.html` in current directory (prefer the most recently modified).

2. **Install dependencies** (first time only)
   - Check if `node_modules/` exists in the skill's `scripts/` directory.
   - If not, run: `cd <skill-path>/scripts && npm install`

3. **Run the export script**
   - Execute: `node <skill-path>/scripts/export-pptx.mjs <presentation.html> [title] [--scale N]`
   - Default scale: 3x (for crisp output). User can pass `--scale 2` for smaller file.

4. **Report results** — PPTX file path and slide count.

---

## CRITICAL: Viewport Fitting Requirements

**This section is mandatory for ALL presentations. Every slide must be fully visible without scrolling on any screen size.**

### The Golden Rule

```
Each slide = exactly one viewport height (100vh/100dvh)
Content overflows? → Split into multiple slides or reduce content
Never scroll within a slide.
```

### Content Density Limits

To guarantee viewport fitting, enforce these limits per slide:

| Slide Type | Maximum Content |
|------------|-----------------|
| Title slide | 1 heading + 1 subtitle + optional tagline |
| Content slide | 1 heading + 4-6 bullet points OR 1 heading + 2 paragraphs |
| Feature grid | 1 heading + 6 cards maximum (2x3 or 3x2 grid) |
| Code slide | 1 heading + 8-10 lines of code maximum |
| Quote slide | 1 quote (max 3 lines) + attribution |
| Image slide | 1 heading + 1 image (max 60vh height) |

**If content exceeds these limits → Split into multiple slides**

### Required CSS Architecture

Every presentation MUST include this base CSS for viewport fitting:

```css
/* ===========================================
   VIEWPORT FITTING: MANDATORY BASE STYLES
   These styles MUST be included in every presentation.
   They ensure slides fit exactly in the viewport.
   =========================================== */

/* 1. Lock html/body to viewport */
html, body {
    height: 100%;
    overflow-x: hidden;
}

html {
    scroll-snap-type: y mandatory;
    scroll-behavior: smooth;
}

/* 2. Each slide = exact viewport height */
.slide {
    width: 100vw;
    height: 100vh;
    height: 100dvh; /* Dynamic viewport height for mobile browsers */
    overflow: hidden; /* CRITICAL: Prevent ANY overflow */
    scroll-snap-align: start;
    display: flex;
    flex-direction: column;
    position: relative;
}

/* 3. Content container with flex for centering */
.slide-content {
    flex: 1;
    display: flex;
    flex-direction: column;
    justify-content: center;
    max-height: 100%;
    overflow: hidden; /* Double-protection against overflow */
    padding: var(--slide-padding);
}

/* 4. ALL typography uses clamp() for responsive scaling */
:root {
    /* Titles scale from mobile to desktop */
    --title-size: clamp(1.5rem, 5vw, 4rem);
    --h2-size: clamp(1.25rem, 3.5vw, 2.5rem);
    --h3-size: clamp(1rem, 2.5vw, 1.75rem);

    /* Body text */
    --body-size: clamp(0.75rem, 1.5vw, 1.125rem);
    --small-size: clamp(0.65rem, 1vw, 0.875rem);

    /* Spacing scales with viewport */
    --slide-padding: clamp(1rem, 4vw, 4rem);
    --content-gap: clamp(0.5rem, 2vw, 2rem);
    --element-gap: clamp(0.25rem, 1vw, 1rem);
}

/* 5. Cards/containers use viewport-relative max sizes */
.card, .container, .content-box {
    max-width: min(90vw, 1000px);
    max-height: min(80vh, 700px);
}

/* 6. Lists auto-scale with viewport */
.feature-list, .bullet-list {
    gap: clamp(0.4rem, 1vh, 1rem);
}

.feature-list li, .bullet-list li {
    font-size: var(--body-size);
    line-height: 1.4;
}

/* 7. Grids adapt to available space */
.grid {
    display: grid;
    grid-template-columns: repeat(auto-fit, minmax(min(100%, 250px), 1fr));
    gap: clamp(0.5rem, 1.5vw, 1rem);
}

/* 8. Images constrained to viewport */
img, .image-container {
    max-width: 100%;
    max-height: min(50vh, 400px);
    object-fit: contain;
}

/* ===========================================
   RESPONSIVE BREAKPOINTS
   Aggressive scaling for smaller viewports
   =========================================== */

/* Short viewports (< 700px height) */
@media (max-height: 700px) {
    :root {
        --slide-padding: clamp(0.75rem, 3vw, 2rem);
        --content-gap: clamp(0.4rem, 1.5vw, 1rem);
        --title-size: clamp(1.25rem, 4.5vw, 2.5rem);
        --h2-size: clamp(1rem, 3vw, 1.75rem);
    }
}

/* Very short viewports (< 600px height) */
@media (max-height: 600px) {
    :root {
        --slide-padding: clamp(0.5rem, 2.5vw, 1.5rem);
        --content-gap: clamp(0.3rem, 1vw, 0.75rem);
        --title-size: clamp(1.1rem, 4vw, 2rem);
        --body-size: clamp(0.7rem, 1.2vw, 0.95rem);
    }

    /* Hide non-essential elements */
    .nav-dots, .keyboard-hint, .decorative {
        display: none;
    }
}

/* Extremely short (landscape phones, < 500px height) */
@media (max-height: 500px) {
    :root {
        --slide-padding: clamp(0.4rem, 2vw, 1rem);
        --title-size: clamp(1rem, 3.5vw, 1.5rem);
        --h2-size: clamp(0.9rem, 2.5vw, 1.25rem);
        --body-size: clamp(0.65rem, 1vw, 0.85rem);
    }
}

/* Narrow viewports (< 600px width) */
@media (max-width: 600px) {
    :root {
        --title-size: clamp(1.25rem, 7vw, 2.5rem);
    }

    /* Stack grids vertically */
    .grid {
        grid-template-columns: 1fr;
    }
}

/* ===========================================
   REDUCED MOTION
   Respect user preferences
   =========================================== */
@media (prefers-reduced-motion: reduce) {
    *, *::before, *::after {
        animation-duration: 0.01ms !important;
        transition-duration: 0.2s !important;
    }

    html {
        scroll-behavior: auto;
    }
}
```

### Overflow Prevention Checklist

Before generating any presentation, mentally verify:

1. ✅ Every `.slide` has `height: 100vh; height: 100dvh; overflow: hidden;`
2. ✅ All font sizes use `clamp(min, preferred, max)`
3. ✅ All spacing uses `clamp()` or viewport units
4. ✅ Content containers have `max-height` constraints
5. ✅ Images have `max-height: min(50vh, 400px)` or similar
6. ✅ Grids use `auto-fit` with `minmax()` for responsive columns
7. ✅ Breakpoints exist for heights: 700px, 600px, 500px
8. ✅ No fixed pixel heights on content elements
9. ✅ Content per slide respects density limits

### When Content Doesn't Fit

If you find yourself with too much content:

**DO:**
- Split into multiple slides
- Reduce bullet points (max 5-6 per slide)
- Shorten text (aim for 1-2 lines per bullet)
- Use smaller code snippets
- Create a "continued" slide
- **When adding images to existing slides:** Move image to new slide or reduce other content first

**DON'T:**
- Reduce font size below readable limits
- Remove padding/spacing entirely
- Allow any scrolling
- Cram content to fit
- Add images without checking if existing content already fills the viewport

### Testing Viewport Fit

After generating, recommend the user test at these sizes:
- Desktop: 1920×1080, 1440×900, 1280×720
- Tablet: 1024×768, 768×1024 (portrait)
- Mobile: 375×667, 414×896
- Landscape phone: 667×375, 896×414

---

## Phase 0: Detect Mode

First, determine what the user wants:

**Mode A: New Presentation**
- User wants to create slides from scratch
- **Check for `PLANNING.md`** — if it exists, read it as source of truth and skip Phase 1/2, jump directly to Phase 3
- Otherwise, proceed to Phase 1 (Content Discovery)

**Mode B: PPT Conversion**
- User has a PowerPoint file (.ppt, .pptx) to convert
- Proceed to Phase 4 (PPT Extraction)

**Mode C: Existing Presentation Enhancement**
- User has an HTML presentation and wants to improve it
- Read the existing file, understand the structure, then enhance
- **CRITICAL: When modifying existing slides, ALWAYS ensure viewport fitting is maintained**

### Mode C: Critical Modification Rules

When enhancing existing presentations, follow these mandatory rules:

**1. Before Adding Any Content:**
- Read the current slide structure and count existing elements
- Check against content density limits (see table above)
- Calculate if the new content will fit within viewport constraints

**2. When Adding Images (MOST COMMON ISSUE):**
- Images must have `max-height: min(50vh, 400px)` or similar viewport constraint
- Check if current slide already has maximum content (1 heading + 1 image)
- If adding an image to a slide with existing content → **Split into two slides**
- Example: If slide has heading + 4 bullets, and user wants to add an image:
  - **DON'T:** Cram image onto same slide
  - **DO:** Create new slide with heading + image, keep bullets on original slide
  - **OR:** Reduce bullets to 2-3 and add image with proper constraints

**3. When Adding Text Content:**
- Max 4-6 bullet points per slide
- Max 2 paragraphs per slide
- If adding content exceeds limits → **Split into multiple slides or create a continuation slide**

**4. Required Checks After ANY Modification:**
```
✅ Does the slide have `overflow: hidden` on `.slide` class?
✅ Are all new elements using `clamp()` for font sizes?
✅ Do new images have viewport-relative max-height?
✅ Does total content respect density limits?
✅ Will this fit on a 1280×720 screen? On mobile portrait?
```

**5. Proactive Reorganization (NOT Optional):**
When you detect that modifications will cause overflow:
- **Automatically split content across slides** — Don't wait for user to ask
- Inform user: "I've reorganized the content across 2 slides to ensure proper viewport fitting"
- Use "continued" pattern for split content (e.g., "Key Features" → "Key Features (Continued)")

**6. Testing After Modifications:**
Mentally verify the modified slide at these viewport sizes:
- Desktop: 1280×720 (smallest common)
- Tablet portrait: 768×1024
- Mobile: 375×667

**If in doubt → Split the content. Never allow scrolling within a slide.**

---

## Phase 1: Content Discovery (New Presentations)

**First: Auto-check `resources/` folder**

Before asking any questions, automatically scan the working directory for a `resources/` folder:
- If present and non-empty: list files, read text/markdown files, note images. Tell the user: "I found X files in `resources/` — I'll use them to inform the presentation."
- If missing or empty: proceed normally without mentioning it.

This is silent background context — don't make the user take action unless they need to add materials.

Before designing, understand the content. Ask via AskUserQuestion:

### Step 1.1: Presentation Context + Images (Single Form)

**IMPORTANT:** Ask ALL 4 questions in a single AskUserQuestion call so the user can fill everything out at once before submitting.

**Question 1: Purpose**
- Header: "Purpose"
- Question: "What is this presentation for?"
- Options:
  - "Pitch deck" — Selling an idea, product, or company to investors/clients
  - "Teaching/Tutorial" — Explaining concepts, how-to guides, educational content
  - "Conference talk" — Speaking at an event, tech talk, keynote
  - "Internal presentation" — Team updates, strategy meetings, company updates

**Question 2: Slide Count**
- Header: "Length"
- Question: "Approximately how many slides?"
- Options:
  - "Short (5-10)" — Quick pitch, lightning talk
  - "Medium (10-20)" — Standard presentation
  - "Long (20+)" — Deep dive, comprehensive talk

**Question 3: Content**
- Header: "Content"
- Question: "Do you have the content ready, or do you need help structuring it?"
- Options:
  - "I have all content ready" — Just need to design the presentation
  - "I have rough notes" — Need help organizing into slides
  - "I have a topic only" — Need help creating the full outline

**Question 4: Images**
- Header: "Images"
- Question: "Do you have images to include? Select 'No images' or select Other and type/paste your image folder path."
- Options:
  - "No images" — Text-only presentation (use CSS-generated visuals instead)
  - "./assets" — Use the `assets/` folder in the current project

The user can select **"Other"** to type or paste any custom folder path (e.g. `~/Desktop/screenshots`). This way the image folder path is collected in the same form — no extra round-trip.

**Question 5: Inline Editing**
- Header: "Editing"
- Question: "Do you need to edit text directly in the browser after generation?"
- Options:
  - "Yes (Recommended)" — Can edit text in-browser, auto-save to localStorage, export file
  - "No" — Presentation only, keeps file smaller

**Remember the user's choice — it determines whether edit-related HTML/CSS/JS is included in Phase 3.**

If user has content, ask them to share it (text, bullet points, images, etc.).

### Step 1.2: Image Evaluation

**User-provided assets are important visual anchors** — but not every asset is necessarily usable. The first step is always to evaluate. After evaluation, the curated assets become additional context that shapes how the presentation is built. This is a **co-design process**: text content + curated visuals together inform the slide structure from the start, not a post-hoc "fit images in after the fact."

**If user selected "No images"** → Skip the entire image pipeline. Proceed directly to Phase 2 (Style Discovery) and Phase 3 (Generate Presentation) using text content only. The presentation will use CSS-generated visuals (gradients, shapes, patterns, typography) for visual interest — this is the original behavior and produces fully polished results without any images.

**If user provides an image folder:**

1. **Scan the folder** — Use `ls` to list all image files (`.png`, `.jpg`, `.jpeg`, `.gif`, `.svg`, `.webp`)
2. **View each image** — Use the Read tool to see what each image contains (Claude is multimodal)
3. **Evaluate each image** — For each image, assess:
   - Filename and dimensions
   - What it shows (screenshot, logo, chart, diagram, photo)
   - **Usability:** Is the image clear, relevant to the presentation topic, and high enough quality? Mark as `USABLE` or `NOT USABLE` (with reason: blurry, irrelevant, broken, etc.)
   - **Content signal:** What feature or concept does this image represent? (e.g., "chat_ui.png" → "conversational interface feature")
   - Shape: square, landscape, portrait, circular
   - Dominant colors (important for style compatibility later)
4. **Present the evaluation and proposed slide outline to the user** — Show which images are usable and which are not, with reasons. Then show the proposed slide outline with image assignments.

**Co-design: curated assets inform the outline**

After evaluation, the **usable** images become context for planning the slide structure alongside text content. This is not "plan slides then add images" — it's designing the presentation around both text and visuals from the start:

- 3 usable product screenshots → plan 3 feature slides, each anchored by one screenshot
- 1 usable logo → title slide and/or closing slide
- 1 usable architecture diagram → dedicated "How It Works" slide
- 1 blurry/irrelevant image → excluded, with explanation to user

This means curated images are factored in **before** style selection (Phase 2) and **before** HTML generation (Phase 3). They are co-equal context in the design process.

5. **Confirm outline via AskUserQuestion** — Do NOT break the flow by asking the user to type free text. Use AskUserQuestion to confirm:

**Question: Outline Confirmation**
- Header: "Outline"
- Question: "Does this slide outline and image selection look right?"
- Options:
  - "Looks good, proceed" — Move on to style selection
  - "Adjust images" — I want to change which images go where
  - "Adjust outline" — I want to change the slide structure

This keeps the entire flow in the AskUserQuestion format without dropping to free-text chat.

---

## Phase 2: Style Discovery (Visual Exploration)

**CRITICAL: This is the "show, don't tell" phase.**

Most people can't articulate design preferences in words. Instead of asking "do you want minimalist or bold?", we generate mini-previews and let them react.

### How Users Choose Presets

Users can select a style in **two ways**:

**Option A: Guided Discovery (Default)**
- User answers mood questions
- Skill generates 3 preview files based on their answers
- User views previews in browser and picks their favorite
- This is best for users who don't have a specific style in mind

**Option B: Direct Selection**
- If user already knows what they want, they can request a preset by name
- Example: "Use the Bold Signal style" or "I want something like Dark Botanical"
- Skip to Phase 3 immediately

**Available Presets:**
| Preset | Vibe | Best For |
|--------|------|----------|
| Bold Signal | Confident, high-impact | Pitch decks, keynotes |
| Electric Studio | Clean, professional | Agency presentations |
| Creative Voltage | Energetic, retro-modern | Creative pitches |
| Dark Botanical | Elegant, sophisticated | Premium brands |
| Notebook Tabs | Editorial, organized | Reports, reviews |
| Pastel Geometry | Friendly, approachable | Product overviews |
| Split Pastel | Playful, modern | Creative agencies |
| Vintage Editorial | Witty, personality-driven | Personal brands |
| Neon Cyber | Futuristic, techy | Tech startups |
| Terminal Green | Developer-focused | Dev tools, APIs |
| Swiss Modern | Minimal, precise | Corporate, data |
| Paper & Ink | Literary, thoughtful | Storytelling |

### Step 2.0: Style Path Selection

First, ask how the user wants to choose their style:

**Question: Style Selection Method**
- Header: "Style"
- Question: "How would you like to choose your presentation style?"
- Options:
  - "Show me options" — Generate 3 previews based on my needs (recommended for most users)
  - "I know what I want" — Let me pick from the preset list directly

**If "Show me options"** → Continue to Step 2.1 (Mood Selection)

**If "I know what I want"** → Show preset picker:

**Question: Pick a Preset**
- Header: "Preset"
- Question: "Which style would you like to use?"
- Options:
  - "Bold Signal" — Vibrant card on dark, confident and high-impact
  - "Dark Botanical" — Elegant dark with soft abstract shapes
  - "Notebook Tabs" — Editorial paper look with colorful section tabs
  - "Pastel Geometry" — Friendly pastels with decorative pills

(If user picks one, skip to Phase 3. If they want to see more options, show additional presets or proceed to guided discovery.)

### Step 2.1: Mood Selection (Guided Discovery)

**Question 1: Feeling**
- Header: "Vibe"
- Question: "What feeling should the audience have when viewing your slides?"
- Options:
  - "Impressed/Confident" — Professional, trustworthy, this team knows what they're doing
  - "Excited/Energized" — Innovative, bold, this is the future
  - "Calm/Focused" — Clear, thoughtful, easy to follow
  - "Inspired/Moved" — Emotional, storytelling, memorable
- multiSelect: true (can choose up to 2)

### Step 2.2: Generate Style Previews

Based on their mood selection, generate **3 distinct style previews** as mini HTML files in a temporary directory. Each preview should be a single title slide showing:

- Typography (font choices, heading/body hierarchy)
- Color palette (background, accent, text colors)
- Animation style (how elements enter)
- Overall aesthetic feel

**Preview Styles to Consider (pick 3 based on mood):**

| Mood | Style Options |
|------|---------------|
| Impressed/Confident | "Bold Signal", "Electric Studio", "Dark Botanical" |
| Excited/Energized | "Creative Voltage", "Neon Cyber", "Split Pastel" |
| Calm/Focused | "Notebook Tabs", "Paper & Ink", "Swiss Modern" |
| Inspired/Moved | "Dark Botanical", "Vintage Editorial", "Pastel Geometry" |

**IMPORTANT: Never use these generic patterns:**
- Purple gradients on white backgrounds
- Inter, Roboto, or system fonts
- Standard blue primary colors
- Predictable hero layouts

**Instead, use distinctive choices:**
- Unique font pairings (Clash Display, Satoshi, Cormorant Garamond, DM Sans, etc.)
- Cohesive color themes with personality
- Atmospheric backgrounds (gradients, subtle patterns, depth)
- Signature animation moments

### Step 2.3: Present Previews

Create the previews in: `.claude-design/slide-previews/`

```
.claude-design/slide-previews/
├── style-a.html   # First style option
├── style-b.html   # Second style option
├── style-c.html   # Third style option
└── assets/        # Any shared assets
```

Each preview file should be:
- Self-contained (inline CSS/JS)
- A single "title slide" showing the aesthetic
- Animated to demonstrate motion style
- ~50-100 lines, not a full presentation

**Logo in previews (if available):** If the user provided images in Step 1.2 and a logo was identified as `USABLE`, embed it (base64) into each of the 3 style previews. This creates a "wow moment" — the user sees their own brand identity styled three different ways, making the choice feel personal rather than abstract. Apply any necessary processing (e.g., circular crop) per-style so each preview shows the logo as it would actually appear in the final presentation. If no logo was provided, generate previews without one — this is fine.

Present to user:
```
I've created 3 style previews for you to compare:

**Style A: [Name]** — [1 sentence description]
**Style B: [Name]** — [1 sentence description]
**Style C: [Name]** — [1 sentence description]

Open each file to see them in action:
- .claude-design/slide-previews/style-a.html
- .claude-design/slide-previews/style-b.html
- .claude-design/slide-previews/style-c.html

Take a look and tell me:
1. Which style resonates most?
2. What do you like about it?
3. Anything you'd change?
```

Then use AskUserQuestion:

**Question: Pick Your Style**
- Header: "Style"
- Question: "Which style preview do you prefer?"
- Options:
  - "Style A: [Name]" — [Brief description]
  - "Style B: [Name]" — [Brief description]
  - "Style C: [Name]" — [Brief description]
  - "Mix elements" — Combine aspects from different styles

If "Mix elements", ask for specifics.

---

## Phase 3: Generate Presentation

Now generate the full presentation based on:
- Content from Phase 1 (text only, or text + curated images)
- Style from Phase 2

If the user provided images, the slide outline already incorporates them as visual anchors from Step 1.2. If not, proceed with text-only content — CSS-generated visuals (gradients, shapes, patterns) provide visual interest.

### Image Pipeline (skip if no images)

If the user chose "No images" in Step 1.2, **skip this entire section** and go straight to generating HTML. The presentation will be text-only with CSS-generated visuals — this is a fully supported, first-class path.

If the user provided images, execute these steps **before** generating HTML.

**Key principle: Co-design, not post-hoc.** The curated images from Step 1.2 (those marked `USABLE`) are already part of the slide outline. The pipeline's job here is to process images for the chosen style and place them in the HTML.

#### Step 3.1: Image Processing (Pillow)

For each curated image, determine what processing it needs based on the chosen style (e.g., circular crop for logos, resize for large files) and what CSS framing will bridge any color gaps between the image and the style's palette. Then process accordingly.

**Rules:**
- **Never repeat** the same image on multiple slides (except logos which may bookend title + closing)
- **Always add CSS framing** (border, glow, shadow) for images whose colors clash with the style's palette

**Dependency:** Python `Pillow` library (the standard image processing library for Python).

```bash
# Install if not available (portable across macOS/Linux/Windows)
pip install Pillow
```

This is analogous to how `python-pptx` is used in Phase 4 (PPT Conversion) — a standard, well-maintained Python package that any user can install.

**Common processing operations:**

```python
from PIL import Image, ImageDraw

# ─── Circular Crop (for logos on modern/clean styles) ───
def crop_circle(input_path, output_path):
    """Crop a square image to a circle with transparent background."""
    img = Image.open(input_path).convert('RGBA')
    w, h = img.size
    # Make square if not already
    size = min(w, h)
    left = (w - size) // 2
    top = (h - size) // 2
    img = img.crop((left, top, left + size, top + size))
    # Create circular mask
    mask = Image.new('L', (size, size), 0)
    draw = ImageDraw.Draw(mask)
    draw.ellipse([0, 0, size, size], fill=255)
    img.putalpha(mask)
    img.save(output_path, 'PNG')

# ─── Resize (for oversized images that inflate the HTML) ───
def resize_max(input_path, output_path, max_dim=1200):
    """Resize image so largest dimension <= max_dim. Preserves aspect ratio."""
    img = Image.open(input_path)
    img.thumbnail((max_dim, max_dim), Image.LANCZOS)
    img.save(output_path, quality=85)

# ─── Add Padding / Background (for images that need breathing room) ───
def add_padding(input_path, output_path, padding=40, bg_color=(0, 0, 0, 0)):
    """Add transparent padding around an image."""
    img = Image.open(input_path).convert('RGBA')
    w, h = img.size
    new = Image.new('RGBA', (w + 2*padding, h + 2*padding), bg_color)
    new.paste(img, (padding, padding), img)
    new.save(output_path, 'PNG')
```

**When to apply each operation:**

| Situation | Operation |
|-----------|-----------|
| Square logo on a style with rounded aesthetics | `crop_circle()` |
| Image > 1MB (slow to load) | `resize_max(max_dim=1200)` |
| Screenshot needs breathing room in layout | `add_padding()` |
| Image has wrong aspect ratio for its slide slot | Manual crop with `img.crop((left, top, right, bottom))` |

**Save processed images** alongside originals with a `_processed` suffix (e.g., `logo_round.png`). Never overwrite the user's original files.

#### Step 3.2: Place Images

**Use direct file paths** — do NOT convert images to base64 data URIs. Since presentations are viewed locally, reference images with relative paths from the HTML file:

```html
<img src="assets/logo_round.png" alt="Logo" class="slide-image logo">
<img src="assets/screenshot.png" alt="Screenshot" class="slide-image screenshot">
```

This keeps the HTML file small and images easy to swap. Only use base64 encoding if the user explicitly requests a fully self-contained single-file presentation.

**Image CSS classes (adapt border/glow colors to match the chosen style):**
```css
/* Base image constraint — CRITICAL for viewport fitting */
.slide-image {
    max-width: 100%;
    max-height: min(50vh, 400px);
    object-fit: contain;
    border-radius: 8px;
}

/* Screenshots: add framing to bridge color gaps with the style */
.slide-image.screenshot {
    border: 1px solid rgba(255, 255, 255, 0.1);
    border-radius: 12px;
    box-shadow: 0 8px 32px rgba(0, 0, 0, 0.3);
}

/* Logos: smaller, no frame */
.slide-image.logo {
    max-height: min(30vh, 200px);
}
```

**IMPORTANT:** Adapt the `.screenshot` border and shadow colors to match the chosen style's accent color. For example:
- Dark Botanical (gold accent): `border: 1px solid rgba(197, 160, 89, 0.2); box-shadow: 0 0 20px rgba(197, 160, 89, 0.08);`
- Creative Voltage (neon yellow): `border: 2px solid rgba(212, 255, 0, 0.25); box-shadow: 0 0 20px rgba(212, 255, 0, 0.08);`

**Placement patterns:**
- **Title slide:** Logo centered above or beside the title
- **Feature slides:** Screenshot on one side, text on the other (two-column layout)
- **Full-bleed:** Image as slide background with text overlay (use with caution)
- **Inline:** Image within content flow, centered, with caption below

**Note:** Processed images (e.g. `logo_round.png`) are saved alongside originals in the assets folder. Reference them with relative paths in the HTML.

### File Structure

For single presentations:
```
presentation.html    # Self-contained presentation
assets/              # Images, if any
```

For projects with multiple presentations:
```
[presentation-name].html
[presentation-name]-assets/
```

### HTML Architecture

Follow this structure for all presentations:

```html
<!DOCTYPE html>
<html lang="en">

### Required JavaScript Features

Every presentation should include:

1. **SlidePresentation Class** — Main controller
   - Keyboard navigation (arrows, space)
   - Touch/swipe support
   - Mouse wheel navigation
   - Progress bar updates
   - Navigation dots

2. **Intersection Observer** — For scroll-triggered animations
   - Add `.visible` class when slides enter viewport
   - Trigger CSS animations efficiently

3. **Optional Enhancements** (based on style):
   - Custom cursor with trail
   - Particle system background (canvas)
   - Parallax effects
   - 3D tilt on hover
   - Magnetic buttons
   - Counter animations
   - **Inline editing** (only if user opted in during content discovery):
     - Edit toggle button (hidden by default, revealed via hover hotzone or `E` key)
     - Auto-save to localStorage
     - Export/save file functionality
     - See "Edit Button Implementation" section below for required code patterns

### Edit Button Implementation (When User Opts In)

**If the user chose "No" for inline editing in Phase 1, skip this entirely — do not generate any edit-related HTML, CSS, or JS.**

**⚠️ Critical: Do NOT use CSS `~` sibling selector for hover-based show/hide.**

The CSS-only approach (`edit-hotzone:hover ~ .edit-toggle`) fails because `pointer-events: none` on the toggle button causes the hover chain to break: user hovers hotzone → button becomes visible → mouse moves toward button → leaves hotzone → button disappears before click reaches it.

**Required approach: JS-based hover with delay timeout.**

HTML structure:
```html
<div class="edit-hotzone"></div>
<button class="edit-toggle" id="editToggle" title="编辑模式 (E)">✏️</button>
```

CSS (visibility controlled by JS classes only):
```css
/* ⚠️ Do NOT use CSS ~ sibling selector for this!
   pointer-events: none breaks the hover chain.
   Must use JS with delay timeout. */
.edit-hotzone {
    position: fixed; top: 0; left: 0;
    width: 80px; height: 80px;
    z-index: 10000;
    cursor: pointer;
}
.edit-toggle {
    opacity: 0;
    pointer-events: none;
    transition: opacity 0.3s ease;
    z-index: 10001;
}
/* Only JS-added classes control visibility */
.edit-toggle.show,
.edit-toggle.active {
    opacity: 1;
    pointer-events: auto;
}
```

JS (all three interaction methods):
```javascript
// 1. Click handler on the toggle button
document.getElementById('editToggle').addEventListener('click', () => {
    editor.toggleEditMode();
});

// 2. Hotzone hover with 400ms grace period
const hotzone = document.querySelector('.edit-hotzone');
const editToggle = document.getElementById('editToggle');
let hideTimeout = null;

hotzone.addEventListener('mouseenter', () => {
    clearTimeout(hideTimeout);
    editToggle.classList.add('show');
});
hotzone.addEventListener('mouseleave', () => {
    hideTimeout = setTimeout(() => {
        if (!editor.isActive) editToggle.classList.remove('show');
    }, 400);
});
editToggle.addEventListener('mouseenter', () => {
    clearTimeout(hideTimeout);
});
editToggle.addEventListener('mouseleave', () => {
    hideTimeout = setTimeout(() => {
        if (!editor.isActive) editToggle.classList.remove('show');
    }, 400);
});

// 3. Hotzone direct click
hotzone.addEventListener('click', () => {
    editor.toggleEditMode();
});

// 4. Keyboard shortcut (E key, skip when editing text)
document.addEventListener('keydown', (e) => {
    if ((e.key === 'e' || e.key === 'E') && !e.target.getAttribute('contenteditable')) {
        editor.toggleEditMode();
    }
});
```

### Code Quality Requirements

**Comments:**
Every section should have clear comments explaining:
- What it does
- Why it exists
- How to modify it

```javascript
/* ===========================================
   CUSTOM CURSOR
   Creates a stylized cursor that follows mouse with a trail effect.
   - Uses lerp (linear interpolation) for smooth movement
   - Grows larger when hovering over interactive elements
   =========================================== */
class CustomCursor {
    constructor() {
        // ...
    }
}
```

**Accessibility:**
- Semantic HTML (`<section>`, `<nav>`, `<main>`)
- Keyboard navigation works
- ARIA labels where needed
- Reduced motion support

```css
@media (prefers-reduced-motion: reduce) {
    .reveal {
        transition: opacity 0.3s ease;
        transform: none;
    }
}
```

**CSS Function Negation:**
- Never negate CSS functions directly — `-clamp()`, `-min()`, `-max()` are silently ignored by browsers with no console error
- Always use `calc(-1 * clamp(...))` instead. See STYLE_PRESETS.md → "CSS Gotchas" for details.

**Responsive & Viewport Fitting (CRITICAL):**

**See the "CRITICAL: Viewport Fitting Requirements" section above for complete CSS and guidelines.**

Quick reference:
- Every `.slide` must have `height: 100vh; height: 100dvh; overflow: hidden;`
- All typography and spacing must use `clamp()`
- Respect content density limits (max 4-6 bullets, max 6 cards, etc.)
- Include breakpoints for heights: 700px, 600px, 500px
- When content doesn't fit → split into multiple slides, never scroll

## Phase 4: PPT Conversion

When converting PowerPoint files:

### Step 4.1: Extract Content

Use Python with `python-pptx` to extract:

```python
from pptx import Presentation
from pptx.util import Inches, Pt
import json
import os
import base64

def extract_pptx(file_path, output_dir):
    """
    Extract all content from a PowerPoint file.
    Returns a JSON structure with slides, text, and images.
    """
    prs = Presentation(file_path)
    slides_data = []

    # Create assets directory
    assets_dir = os.path.join(output_dir, 'assets')
    os.makedirs(assets_dir, exist_ok=True)

    for slide_num, slide in enumerate(prs.slides):
        slide_data = {
            'number': slide_num + 1,
            'title': '',
            'content': [],
            'images': [],
            'notes': ''
        }

        for shape in slide.shapes:
            # Extract title
            if shape.has_text_frame:
                if shape == slide.shapes.title:
                    slide_data['title'] = shape.text
                else:
                    slide_data['content'].append({
                        'type': 'text',
                        'content': shape.text
                    })

            # Extract images
            if shape.shape_type == 13:  # Picture
                image = shape.image
                image_bytes = image.blob
                image_ext = image.ext
                image_name = f"slide{slide_num + 1}_img{len(slide_data['images']) + 1}.{image_ext}"
                image_path = os.path.join(assets_dir, image_name)

                with open(image_path, 'wb') as f:
                    f.write(image_bytes)

                slide_data['images'].append({
                    'path': f"assets/{image_name}",
                    'width': shape.width,
                    'height': shape.height
                })

        # Extract notes
        if slide.has_notes_slide:
            notes_frame = slide.notes_slide.notes_text_frame
            slide_data['notes'] = notes_frame.text

        slides_data.append(slide_data)

    return slides_data
```

### Step 4.2: Confirm Content Structure

Present the extracted content to the user:

```
I've extracted the following from your PowerPoint:

**Slide 1: [Title]**
- [Content summary]
- Images: [count]

**Slide 2: [Title]**
- [Content summary]
- Images: [count]

...

All images have been saved to the assets folder.

Does this look correct? Should I proceed with style selection?
```

### Step 4.3: Style Selection

Proceed to Phase 2 (Style Discovery) with the extracted content in mind.

### Step 4.4: Generate HTML

Convert the extracted content into the chosen style, preserving:
- All text content
- All images (referenced from assets folder)
- Slide order
- Any speaker notes (as HTML comments or separate file)

---

## Phase 5: Delivery

### Final Output

When the presentation is complete:

1. **Clean up temporary files**
   - Delete `.claude-design/slide-previews/` if it exists

2. **Generate speaker notes** (if deck has 8+ slides OR was created from PLANNING.md)
   - Create `PRESENTATION_SCRIPT.md` in the working directory
   - For each slide: 2-4 sentences of what to say, key emphasis points, transition to next slide
   - Format:
     ```markdown
     # Presentation Script

     ## Slide 1: [Title]
     [2-4 sentences of speaker notes]

     ## Slide 2: [Title]
     [Speaker notes...]
     ```

3. **Open the presentation**
   - Use `open [filename].html` to launch in browser

4. **Provide summary**
```
Your presentation is ready!

📁 File: [filename].html
🎨 Style: [Style Name]
📊 Slides: [count]

**Navigation:**
- Arrow keys (← →) or Space to navigate
- Scroll/swipe also works
- Click the dots on the right to jump to a slide

**To customize:**
- Colors: Look for `:root` CSS variables at the top
- Fonts: Change the Fontshare/Google Fonts link
- Animations: Modify `.reveal` class timings

Would you like me to make any adjustments?

**To export as PPTX:**
Run: `/slide-creator --export pptx` (requires Node.js ≥ 18)
```

If the user opted in to inline editing, also include:

## Style Reference: Effect → Feeling Mapping

Use this guide to match animations to intended feelings:

### Dramatic / Cinematic
- Slow fade-ins (1-1.5s)
- Large scale transitions (0.9 → 1)
- Dark backgrounds with spotlight effects
- Parallax scrolling
- Full-bleed images

### Techy / Futuristic
- Neon glow effects (box-shadow with accent color)
- Particle systems (canvas background)
- Grid patterns
- Monospace fonts for accents
- Glitch or scramble text effects
- Cyan, magenta, electric blue palette

### Playful / Friendly
- Bouncy easing (spring physics)
- Rounded corners (large radius)
- Pastel or bright colors
- Floating/bobbing animations
- Hand-drawn or illustrated elements

### Professional / Corporate
- Subtle, fast animations (200-300ms)
- Clean sans-serif fonts
- Navy, slate, or charcoal backgrounds
- Precise spacing and alignment
- Minimal decorative elements
- Data visualization focus

### Calm / Minimal
- Very slow, subtle motion
- High whitespace
- Muted color palette
- Serif typography
- Generous padding
- Content-focused, no distractions

### Editorial / Magazine
- Strong typography hierarchy
- Pull quotes and callouts

## Animation Patterns Reference

### Entrance Animations

```css
/* Fade + Slide Up (most common) */
.reveal {
    opacity: 0;
    transform: translateY(30px);
    transition: opacity 0.6s var(--ease-out-expo),
                transform 0.6s var(--ease-out-expo);
}

.visible .reveal {
    opacity: 1;
    transform: translateY(0);
}

/* Scale In */
.reveal-scale {
    opacity: 0;
    transform: scale(0.9);
    transition: opacity 0.6s, transform 0.6s var(--ease-out-expo);
}

/* Slide from Left */
.reveal-left {
    opacity: 0;
    transform: translateX(-50px);
    transition: opacity 0.6s, transform 0.6s var(--ease-out-expo);
}

/* Blur In */
.reveal-blur {
    opacity: 0;
    filter: blur(10px);
    transition: opacity 0.8s, filter 0.8s var(--ease-out-expo);
}
```

### Background Effects

```css
/* Gradient Mesh */
.gradient-bg {
    background:
        radial-gradient(ellipse at 20% 80%, rgba(120, 0, 255, 0.3) 0%, transparent 50%),
        radial-gradient(ellipse at 80% 20%, rgba(0, 255, 200, 0.2) 0%, transparent 50%),
        var(--bg-primary);
}

/* Noise Texture */
.noise-bg {
    background-image: url("data:image/svg+xml,..."); /* Inline SVG noise */
}

/* Grid Pattern */
.grid-bg {
    background-image:
        linear-gradient(rgba(255,255,255,0.03) 1px, transparent 1px),
        linear-gradient(90deg, rgba(255,255,255,0.03) 1px, transparent 1px);
    background-size: 50px 50px;
}
```

### Interactive Effects

```javascript
/* 3D Tilt on Hover */
class TiltEffect {
    constructor(element) {
        this.element = element;
        this.element.style.transformStyle = 'preserve-3d';
        this.element.style.perspective = '1000px';
        this.bindEvents();
    }

    bindEvents() {
        this.element.addEventListener('mousemove', (e) => {
            const rect = this.element.getBoundingClientRect();
            const x = (e.clientX - rect.left) / rect.width - 0.5;
            const y = (e.clientY - rect.top) / rect.height - 0.5;

            this.element.style.transform = `
                rotateY(${x * 10}deg)
                rotateX(${-y * 10}deg)
            `;
        });

        this.element.addEventListener('mouseleave', () => {
            this.element.style.transform = 'rotateY(0) rotateX(0)';
        });
    }
}
```

## Troubleshooting

### Common Issues

**Fonts not loading:**
- Check Fontshare/Google Fonts URL
- Ensure font names match in CSS

**Animations not triggering:**
- Verify Intersection Observer is running
- Check that `.visible` class is being added

**Scroll snap not working:**
- Ensure `scroll-snap-type` on html/body
- Each slide needs `scroll-snap-align: start`

**Mobile issues:**
- Disable heavy effects at 768px breakpoint
- Test touch events
- Reduce particle count or disable canvas

**Performance issues:**
- Use `will-change` sparingly
- Prefer `transform` and `opacity` animations
- Throttle scroll/mousemove handlers

## Example Session Flow

1. User: "I want to create a pitch deck for my AI startup"
2. Skill asks about purpose, length, content, and images (single form)
3. User shares bullet points, selects `./assets` folder
4. **Evaluate:** Skill views each image (multimodal), builds slide outline with image assignments:
   - `logo.png` → USABLE → title/closing slide
   - `chat_ui.png` → USABLE → feature slide
   - `dashboard.png` → USABLE → feature slide
   - `launch_card.png` → USABLE → feature slide
   - `blurry_team.jpg` → NOT USABLE (too low resolution)
5. User confirms outline via AskUserQuestion
6. Skill asks about desired feeling (Impressed + Excited)
7. Skill generates 3 style previews
8. User picks Style B (Neon Cyber)
9. **Process + Generate:** Skill runs Pillow operations (circular crop, resize), generates full presentation with direct image paths
10. Skill opens the presentation in browser
11. User requests tweaks to specific slides
12. Final presentation delivered
