# McKinsey PPT Design Framework

## Overview

This skill encodes the complete design specification for **professional business presentations** — a consultant-grade PowerPoint framework based on McKinsey design principles. It includes:

- **36 layout patterns** across 7 categories (structure, data, framework, comparison, narrative, timeline, team)
- **Color system** and strict typography hierarchy
- **Python-pptx code patterns** ready to copy and customize
- **Three-layer defense** against file corruption (zero `p:style` leaks)
- **Chinese + English font handling** (KaiTi / Georgia / Arial)

All specifications have been refined through iterative user feedback to ensure visual consistency and professional polish.

---

## When to Use This Skill

Use this skill when users ask to:

1. **Create presentations** — pitch decks, strategy presentations, quarterly reviews, board meeting slides, consulting deliverables, project proposals, business plans
2. **Generate slides programmatically** — using python-pptx to produce .pptx files from scratch
3. **Apply professional design** — McKinsey / BCG / Bain consulting style, clean flat design, no shadows or gradients
4. **Build specific slide types** — cover pages, data dashboards, 2x2 matrices, timelines, funnels, team introductions, executive summaries, comparison layouts
5. **Fix PPT issues** — file corruption ("needs repair"), shadow/3D artifacts, inconsistent fonts, Chinese text rendering problems
6. **Maintain design consistency** — unified color palette, font hierarchy, spacing, and line treatments across all slides

---

## Core Design Philosophy

### McKinsey Design Principles

1. **Extreme Minimalism** - Remove all non-essential visual elements
   - No color blocks unless absolutely necessary
   - Lines: thin, flat, no shadows or 3D effects
   - Shapes: simple, clean, no gradients
   - Text: clear hierarchy, maximum readability

2. **Consistency** - Repeat visual language across all slides
   - Unified color palette (navy + cyan + grays)
   - Consistent font sizes and weights for same content types
   - Aligned spacing and margins
   - Matching line widths and styles

3. **Hierarchy** - Guide viewer through information
   - Title bar (22pt) → Sub-headers (18pt) → Body (14pt) → Details (9pt)
   - Navy for primary elements, gray for secondary, black for divisions
   - Visual weight through bold, color, size (not through effects)

4. **Flat Design** - No 3D, shadows, or gradients
   - Pure solid colors only
   - All lines are simple strokes with no effects
   - Shapes have no shadow or reflection effects
   - Circles are solid fills, not 3D spheres

## Design Specifications

### Color Palette

All colors in RGB format for python-pptx:

| Color Name | Hex | RGB | Usage | Notes |
|-----------|-----|-----|-------|-------|
| **NAVY** | #051C2C | (5, 28, 44) | Primary, titles, circles | Corporate, formal tone |
| **CYAN** | #00A9F4 | (0, 169, 244) | Originally used in v1 | **DEPRECATED** - Use NAVY for consistency |
| **WHITE** | #FFFFFF | (255, 255, 255) | Backgrounds, text | On navy backgrounds only |
| **BLACK** | #000000 | (0, 0, 0) | Lines, text separators | For clarity and contrast |
| **DARK_GRAY** | #333333 | (51, 51, 51) | Body text, descriptions | Main content text |
| **MED_GRAY** | #666666 | (102, 102, 102) | Secondary text, labels | Softer tone than DARK_GRAY |
| **LINE_GRAY** | #CCCCCC | (204, 204, 204) | Light separators, table rows | Table separators only |
| **BG_GRAY** | #F2F2F2 | (242, 242, 242) | Background panels | Takeaway/highlight areas |

**Key Rule**: Use navy (#051C2C) everywhere, especially for:
- All circle indicators (A, B, C, 1, 2, 3)
- All action titles
- All primary section headers
- All TOC highlight colors

---

### Typography System

#### Font Families

```
English Headers:  Georgia (serif, elegant)
English Body:     Arial (sans-serif, clean)
Chinese (ALL):    KaiTi (楷体, traditional brush style)
                  (fallback: SimSun 宋体)
```

**Critical Implementation**:
```python
def set_ea_font(run, typeface='KaiTi'):
    """Set East Asian font for Chinese text"""
    rPr = run._r.get_or_add_rPr()
    ea = rPr.find(qn('a:ea'))
    if ea is None:
        ea = rPr.makeelement(qn('a:ea'), {})
        rPr.append(ea)
    ea.set('typeface', typeface)
```

Every paragraph with Chinese text MUST apply `set_ea_font()` to all runs.

#### Font Size Hierarchy

| Size | Type | Examples | Notes |
|------|------|----------|-------|
| **44pt** | Cover Title | "项目名称" | Cover slide only, Georgia |
| **28pt** | Section Header | "目录" (TOC title) | Largest body content, Georgia |
| **24pt** | Subtitle | Tagline on cover | Cover slide only |
| **22pt** | Action Title | Slide title bars | Main content titles, **bold**, Georgia |
| **18pt** | Sub-Header | Column headers, section names | Supporting titles |
| **16pt** | Emphasis Text | Bottom takeaway on slide 8 | Callout text, bold |
| **14pt** | Body Text | Tables, lists, descriptions | **PRIMARY BODY SIZE**, all main content |
| **9pt** | Footnote | Source attribution | Smallest, gray color only |

**No other sizes should be used** - stick to this hierarchy exclusively.

---

### Line Treatment (CRITICAL)

#### Line Rendering Rules

1. **All lines are FLAT** - no shadows, no effects, no 3D
2. **Remove theme style references** - prevents automatic shadow application
3. **Solid color only** - no gradients or patterns
4. **Width varies by context** - see table below

#### Line Width Specifications

| Usage | Width | Color | Context |
|-------|-------|-------|---------|
| **Title separator** (under action titles) | 0.5pt | BLACK | Below 22pt title |
| **Column/section divider** (under headers) | 0.5pt | BLACK | Below 18pt headers |
| **Table header line** | 1.0pt | BLACK | Between header and first row |
| **Table row separator** | 0.5pt | LINE_GRAY (#CCCCCC) | Between table rows |
| **Timeline line** (roadmap) | 0.75pt | LINE_GRAY | Background for phase indicators |
| **Cover accent line** | 2.0pt | NAVY | Decorative bottom-left on cover |
| **Column internal divider** | 0.5pt | BLACK | Between "是什么" and "独到之处" |

#### Code Implementation (v1.1 — Rectangle-based Lines)

**CRITICAL**: Do NOT use `slide.shapes.add_connector()` for lines. Connectors carry `<p:style>` elements that reference theme effects and cause file corruption. Instead, draw lines as ultra-thin rectangles:

```python
def add_hline(slide, x, y, length, color=BLACK, thickness=Pt(0.5)):
    """Draw a horizontal line using a thin rectangle (no connector, no p:style)."""
    from pptx.util import Emu
    h = max(int(thickness), Emu(6350))  # minimum ~0.5pt
    return add_rect(slide, x, y, length, h, color)
```

**IMPORTANT**: Never use `add_connector()` — it causes file corruption. Always use `add_hline()` (thin rectangle).

#### Post-Save Full Cleanup (v1.1 — Nuclear Sanitization)

After `prs.save(outpath)`, ALWAYS run full cleanup that sanitizes **both** theme XML **and** all slide XML:

```python
import zipfile, os
from lxml import etree

def full_cleanup(outpath):
    """Remove ALL p:style from every slide + theme shadows/3D."""
    tmppath = outpath + '.tmp'
    with zipfile.ZipFile(outpath, 'r') as zin:
        with zipfile.ZipFile(tmppath, 'w', zipfile.ZIP_DEFLATED) as zout:
            for item in zin.infolist():
                data = zin.read(item.filename)
                if item.filename.endswith('.xml'):
                    root = etree.fromstring(data)
                    ns_p = 'http://schemas.openxmlformats.org/presentationml/2006/main'
                    ns_a = 'http://schemas.openxmlformats.org/drawingml/2006/main'
                    # Remove ALL p:style elements from all shapes/connectors
                    for style in root.findall(f'.//{{{ns_p}}}style'):
                        style.getparent().remove(style)
                    # Remove shadows and 3D from theme
                    if 'theme' in item.filename.lower():
                        for tag in ['outerShdw', 'innerShdw', 'scene3d', 'sp3d']:
                            for el in root.findall(f'.//{{{ns_a}}}{tag}'):
                                el.getparent().remove(el)
                    data = etree.tostring(root, xml_declaration=True,
                                          encoding='UTF-8', standalone=True)
                zout.writestr(item, data)
    os.replace(tmppath, outpath)
```

---

### Text Box & Shape Treatment

#### Text Box Padding

All text boxes must have consistent internal padding to prevent text touching edges:

```python
bodyPr = tf._txBody.find(qn('a:bodyPr'))
# All margins: 45720 EMUs = ~0.05 inches
for attr in ['lIns','tIns','rIns','bIns']:
    bodyPr.set(attr, '45720')
```

#### Vertical Anchoring

Text must be anchored correctly based on usage:

| Content Type | Anchor | Code | Notes |
|--------------|--------|------|-------|
| Action titles | MIDDLE | `anchor='ctr'` | Centered vertically in bar |
| Body text | TOP | `anchor='t'` | Default, aligns to top |
| Labels | CENTER | `anchor='ctr'` | For circle labels |

```python
anchor_map = {
    MSO_ANCHOR.MIDDLE: 'ctr', 
    MSO_ANCHOR.BOTTOM: 'b', 
    MSO_ANCHOR.TOP: 't'
}
bodyPr.set('anchor', anchor_map.get(anchor, 't'))
```

#### Shape Styling

All shapes (rectangles, circles) must have:
- Solid fill color (no gradients)
- NO border/line (`shape.line.fill.background()`)
- **p:style removed** immediately after creation (`_clean_shape()`)
- No shadow effects (enforced by both inline cleanup and post-save full_cleanup)

```python
def _clean_shape(shape):
    """Remove p:style from any shape to prevent effect references."""
    sp = shape._element
    style = sp.find(qn('p:style'))
    if style is not None:
        sp.remove(style)

shape = slide.shapes.add_shape(MSO_SHAPE.RECTANGLE, left, top, width, height)
shape.fill.solid()
shape.fill.fore_color.rgb = BG_GRAY
shape.line.fill.background()  # CRITICAL: removes border
_clean_shape(shape)            # CRITICAL: removes p:style
```

## Layout Patterns

### Slide Dimensions

```python
prs.slide_width = Inches(13.333)
prs.slide_height = Inches(7.5)
```

Widescreen format (16:9), standard for all presentations.

### Standard Margin/Padding

| Position | Size | Usage |
|----------|------|-------|
| **Left margin** | 0.8" | Default left edge |
| **Right margin** | 0.8" | Default right edge |
| **Top (below title)** | 1.4" | Content start position |
| **Bottom** | 7.05" | Source text baseline |
| **Title bar height** | 0.9" | Action title bar |
| **Title bar top** | 0.15" | From slide top |

### Slide Type Patterns

#### 1. Cover Slide (Slide 1)

Layout:
- Navy bar at very top (0.05" height)
- Main title centered (44pt, Georgia, navy) at y=2.2"
- Subtitle (24pt, dark gray) at y=3.5"
- Date/info (14pt, med gray) at y=4.5"
- Decorative navy line at x=1", y=6.8" (2" wide, 2pt)

Code template:
```python
s1 = prs.slides.add_slide(prs.slide_layouts[6])
add_rect(s1, 0, 0, prs.slide_width, Inches(0.05), NAVY)
add_text(s1, Inches(1), Inches(2.2), Inches(11), Inches(1.0),
         '项目名称', font_size=Pt(44), font_name='Georgia',
         font_color=NAVY, bold=True, ea_font='KaiTi')
add_text(s1, Inches(1), Inches(3.5), Inches(11), Inches(0.6),
         '副标题描述', font_size=Pt(24),
         font_color=DARK_GRAY, ea_font='KaiTi')
add_text(s1, Inches(1), Inches(4.5), Inches(11), Inches(0.5),
         '演示文稿  |  2026年3月', font_size=BODY_SIZE,
         font_color=MED_GRAY, ea_font='KaiTi')
add_line(s1, Inches(1), Inches(6.8), Inches(4), Inches(6.8),
         color=NAVY, width=Pt(2))
```

#### 2. Action Title Slide (Most Content Slides)

Every main content slide has this structure:

```
┌─────────────────────────────────────────┐ 0.15"
│ ▌ Action Title (22pt, bold, black)      │ ← TITLE_BAR_H = 0.9"
├─────────────────────────────────────────┤ 1.05"
│                                         │
│  Content area (starts at 1.4")          │
│  [Tables, lists, text, etc.]            │
│                                         │
│                                         │
│  ──────────────────────────────────────  │ 7.05"
│  Source: ...                            │ 9pt, med gray
└─────────────────────────────────────────┘ 7.5"
```

Code pattern:
```python
s = prs.slides.add_slide(prs.slide_layouts[6])
add_action_title(s, 'Slide Title Here')
# Then add content below y=1.4"
add_source(s, 'Source attribution')
```

#### 3. Table Layout (Slide 4 - Five Capabilities)

Structure:
- Header row with column names (BODY_SIZE, gray, bold)
- 1.0pt black line under header
- Data rows (1.0" height each, 14pt text)
- 0.5pt gray line between rows
- 3 columns: Module (1.6" wide), Function (5.0"), Scene (5.1")

```python
# Headers
add_text(s4, left, top, width, height, text,
         font_size=BODY_SIZE, font_color=MED_GRAY, bold=True)

# Header line (thicker)
add_line(s4, left, top + Inches(0.5), left + full_width, top + Inches(0.5),
         color=BLACK, width=Pt(1.0))

# Rows
for i, (col1, col2, col3) in enumerate(rows):
    y = header_y + row_height * i
    add_text(s4, left, y, col1_w, row_h, col1, ...)
    add_text(s4, left + col1_w, y, col2_w, row_h, col2, ...)
    add_text(s4, left + col1_w + col2_w, y, col3_w, row_h, col3, ...)
    # Row separator
    add_line(s4, left, y + row_h, left + full_w, y + row_h,
             color=LINE_GRAY, width=Pt(0.5))
```

#### 4. Three-Column Overview (Slide 5)

Layout:
- Left column (4.1" wide): "是什么"
- Middle column (4.1" wide): "独到之处"
- Right 1/4 (2.5" wide) gray panel: "Key Takeaways"

```
0.8"  4.9"  5.3"  9.4"  10.0" 12.5"
|-----|-----|-----|-----|------|
│左 │ │ 中 │ │ 右 │
└─────────────────────────────┘
```

Code:
```python
left_x = Inches(0.8)
col_w5 = Inches(4.1)
mid_x = Inches(5.3)
takeaway_left = Inches(10.0)
takeaway_width = Inches(2.5)

# Left column
add_text(s5, left_x, content_top, col_w5, ...)
add_text(s5, left_x, content_top + Inches(0.6), col_w5, ..., 
              bullet=True, line_spacing=Pt(8))

# Right gray takeaway area
add_rect(s5, takeaway_left, Inches(1.2), takeaway_width, Inches(5.6), BG_GRAY)
add_text(s5, takeaway_left + Inches(0.15), Inches(1.35), takeaway_width - Inches(0.3), ...,
         'Key Takeaways', font_size=BODY_SIZE, color=NAVY, bold=True)
add_text(s5, takeaway_left + Inches(0.15), Inches(1.9), takeaway_width - Inches(0.3), ...,
              [f'{i+1}. {t}' for i, t in enumerate(takeaways)], line_spacing=Pt(10))
```

## Common Issues & Solutions

### Problem 1: PPT Won't Open / "File Needs Repair"

**Cause**: Shapes or connectors carry `<p:style>` with `effectRef idx="2"`, referencing theme effects (shadows/3D)

**Solution** (three-layer defense):
1. **Never use connectors** — use `add_hline()` (thin rectangle) instead of `add_connector()`
2. **Inline cleanup** — every `add_rect()` and `add_oval()` calls `_clean_shape()` to remove `p:style`
3. **Post-save cleanup** — `full_cleanup()` removes ALL `<p:style>` from every slide XML + theme effects

### Problem 2: Text Not Displaying Correctly in PowerPoint

**Cause**: Chinese characters rendered as English font instead of KaiTi

**Solution**:
- Use `set_ea_font(run, 'KaiTi')` in every paragraph with Chinese text
- Call it inside the loop that creates runs:
  ```python
  for run in p.runs:
      set_ea_font(run, 'KaiTi')
  ```

### Problem 3: Font Sizes Inconsistent Across Slides

**Cause**: Using custom sizes instead of defined hierarchy

**Solution**:
- Define constants:
  ```python
  TITLE_SIZE = Pt(22)
  BODY_SIZE = Pt(14)
  SUB_HEADER_SIZE = Pt(18)
  LABEL_SIZE = Pt(14)
  SMALL_SIZE = Pt(9)
  ```
- Use these constants everywhere
- Never use arbitrary sizes like `Pt(13)` or `Pt(15)`

### Problem 4: Columns/Lists Not Aligning Vertically

**Cause**: Mixing different line spacing or not accounting for text height

**Solution**:
- Use consistent `line_spacing=Pt(N)` in `add_text()` calls
- Calculate row heights in tables based on actual text size:
  - For 14pt text with spacing: use 1.0" height minimum
  - For lists with bullets: use 0.35" height per line + 8pt spacing
- Test by saving and opening in PowerPoint to verify alignment

## Edge Cases

### Handling Large Presentations (20+ Slides)

- Break generation into batches of 5-8 slides, saving and verifying after each batch
- Always call `full_cleanup()` once at the end, not per-batch
- Memory: python-pptx holds the entire presentation in memory; for 50+ slides, monitor usage

### Font Availability

- **KaiTi / SimSun** may not be installed on non-Chinese systems — the presentation will render but fall back to a default CJK font
- **Georgia** is available on Windows/macOS by default; on Linux, install `ttf-mscorefonts-installer`
- If target audience uses macOS only, consider using `PingFang SC` as `ea_font` fallback

### Slide Dimensions

- All layouts assume **13.333" × 7.5"** (widescreen 16:9). Using 4:3 or custom sizes will break coordinate calculations
- If custom dimensions are required, scale all `Inches()` values proportionally

### PowerPoint vs LibreOffice

- Generated files are optimized for **Microsoft PowerPoint** (Windows/macOS)
- LibreOffice Impress may render fonts and spacing slightly differently
- `full_cleanup()` is still recommended for LibreOffice compatibility

## Best Practices

1. **Always start from scratch** - Don't try to edit existing .pptx files with python-pptx; regenerate
2. **Test early** - Save and open in PowerPoint after every 2-3 slides to catch issues
3. **Use constants** - Define all colors, sizes, positions as named constants at the top
4. **Keep code DRY** - Use helper functions like `add_text()`, `add_hline()`, `add_oval()`, etc.
5. **Never use connectors** - Always draw lines as thin rectangles via `add_hline()`
6. **Validate XML** - After `full_cleanup()`, verify zero `p:style` and zero shadows remain
6. **Document decisions** - Comment code explaining why specific colors/sizes are chosen
7. **Version control** - Save Python generation script alongside .pptx output

---

## Dependencies

- **python-pptx** >= 0.6.21 - For PowerPoint generation
- **lxml** - For XML processing during theme cleanup
- **zipfile** (built-in) - For PPTX manipulation
- Python 3.8+

Install with:
```bash
pip install python-pptx lxml
```

## Example: Complete Minimal Presentation

See `scripts/minimal_example.py` for a complete, working example that generates:
- Cover slide
- Table of contents
- Content slide with title + body text
- Source attribution
- Proper theme cleanup

---

## File References

Generated presentations are typically saved to:
```
./output/presentation.pptx
```

All colors, fonts, and dimensions referenced in code should match this document exactly.
