McKinsey PPT Design Framework

Version: 1.10.4 · License: Apache-2.0 · Author: likaku

Required tools: Read, Write, Bash · Requires: python3, pip

Overview

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

70 layout patterns across 12 categories (structure, data, framework, comparison, narrative, timeline, team, charts, images, advanced viz, dashboards, visual storytelling)
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)
Image placeholder system for image-containing layouts (v1.8)
BLOCK_ARC native shapes for charts — donut, pie, gauge rendered with 3-4 shapes instead of hundreds of blocks, 60-80% smaller files (v2.0)
Production Guard Rails — 9 mandatory rules including spacing/overflow protection, legend color consistency, title style uniformity, axis label centering, dynamic sizing, BLOCK_ARC chart rendering (v1.9+v2.0)
Code Efficiency guidelines — variable reuse patterns, constant extraction, loop optimization for faster generation (v1.9)

All specifications have been refined through iterative production feedback to ensure visual consistency, professional polish, and zero-defect output.

When to Use This Skill

Use this skill when users ask to:

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

Core Design Philosophy

McKinsey Design Principles

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
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
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)
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

Accent Colors (for multi-item differentiation)

When a slide contains 3 or more parallel items (e.g., comparison cards, pillar frameworks, multi-category overviews), use these accent colors to create visual distinction between items. Without accent colors, parallel items become visually indistinguishable.

Accent Name	Hex	RGB	Paired Light BG	Usage
ACCENT_BLUE	#006BA6	(0, 107, 166)	#E3F2FD	First item accent
ACCENT_GREEN	#007A53	(0, 122, 83)	#E8F5E9	Second item accent
ACCENT_ORANGE	#D46A00	(212, 106, 0)	#FFF3E0	Third item accent
ACCENT_RED	#C62828	(198, 40, 40)	#FFEBEE	Fourth item / warning

Accent Color Rules:

Use accent colors for: card top accent borders (thin 0.06" rect), circle labels (add_oval() bg param), section sub-headers (font_color)
Use paired light BG for: card background fills only
Body text inside cards ALWAYS remains DARK_GRAY (#333333)
NAVY remains the primary color for single-focus elements (one card, one stat, cover title)
Use accent colors ONLY when the slide has 3+ parallel items that need visual distinction
The fourth item (D) can use NAVY instead of ACCENT_RED if red feels inappropriate for the content

# Accent color constants
ACCENT_BLUE   = RGBColor(0x00, 0x6B, 0xA6)
ACCENT_GREEN  = RGBColor(0x00, 0x7A, 0x53)
ACCENT_ORANGE = RGBColor(0xD4, 0x6A, 0x00)
ACCENT_RED    = RGBColor(0xC6, 0x28, 0x28)
LIGHT_BLUE    = RGBColor(0xE3, 0xF2, 0xFD)
LIGHT_GREEN   = RGBColor(0xE8, 0xF5, 0xE9)
LIGHT_ORANGE  = RGBColor(0xFF, 0xF3, 0xE0)
LIGHT_RED     = RGBColor(0xFF, 0xEB, 0xEE)

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:

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

All lines are FLAT - no shadows, no effects, no 3D
Remove theme style references - prevents automatic shadow application
Solid color only - no gradients or patterns
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:

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:

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:

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

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)

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

Presentation Planning

This section provides mandatory guidance for planning presentation structure, selecting layouts, and ensuring adequate content density. These rules dramatically improve output quality across different LLM models.

Layout Diversity Requirement

Each content slide MUST use a DIFFERENT layout pattern from its neighbors. Repeating the same layout on consecutive slides makes the presentation feel monotonous and unprofessional.

Match content type to the optimal layout pattern:

Content Type	Recommended Layouts	Avoid
Single key statistic	Big Number (#8)	Plain text
2 options comparison	Side-by-Side (#19), Before/After (#20), Metric Comparison Row (#62)	Two-column text
3-4 parallel concepts	Three-Pillar (#14), Four-Column (#27), Metric Cards (#10), Icon Grid (#63)	Bullet list
Process / steps	Process Chevron (#16), Vertical Steps (#30), Value Chain (#67)	Numbered text
Timeline	Timeline/Roadmap (#29), Cycle (#31)	Bullet list
Data table	Data Table (#9), Scorecard (#22), Harvey Ball Table (#56)	Plain text
Case study	Case Study (#33), Case Study with Image (#45)	Two-column text
Summary / conclusion	Executive Summary (#24), Key Takeaway (#25)	Bullet list
Multiple KPIs	Three-Stat Dashboard (#12), Two-Stat Comparison (#11), KPI Tracker (#52), Dashboard (#57)	Plain text
Time series + values/percentages	Grouped Bar (#37), Stacked Bar (#38), Line Chart (#50), Stacked Area (#70)	Data Table, Scorecard
Category ranking / comparison	Horizontal Bar (#39), Grouped Bar (#37), Pareto (#51)	Bullet list, Plain text
Part-of-whole / composition	Donut (#48), Pie (#64), Stacked Bar (#38)	Bullet list
Content with visual / photo	Content+Right Image (#40), Left Image+Content (#41), Three Images (#42)	Text-only layouts
Risk / evaluation matrix	Risk Matrix (#54), SWOT (#65), Harvey Ball (#56), 2x2 Matrix (#13)	Bullet list
Strategic recommendations	Numbered List+Panel (#69), Decision Tree (#60), Checklist (#61)	Two-column text
Multi-KPI executive dashboard	Dashboard KPI+Chart (#57), Dashboard Table+Chart (#58)	Simple table
Stakeholder / relationship	Stakeholder Map (#59)	Bullet list
Meeting agenda	Agenda (#66)	Plain text

NEVER use Two-Column Text (#26) for more than 1 slide per deck. It is the least visually engaging layout.

CHART PRIORITY RULE: When data contains dates/periods + numeric values or percentages (e.g., 3/4 正面 20% 中性 80% or Q1: ¥850万), you MUST use a Chart pattern (#37-#39, #48-#56, #64, #70) instead of a text-based layout. Charts maximize data-ink ratio and are the most visually compelling way to present time-series data.

IMAGE PRIORITY RULE (v1.8): When the content involves case studies, product showcases, location overviews, or any scenario where a visual/photo would strengthen the narrative, prefer Image+Content layouts (#40-#47, #68) over text-only layouts. The add_image_placeholder() function creates gray placeholder boxes that users replace with real images after generation.

Content Density Requirements

"Minimalism" in McKinsey design means removing decorative noise (shadows, gradients, clip-art), NOT removing content. A slide with 80% whitespace is not minimalist — it is EMPTY.

Mandatory minimums per content slide:

At least 3 distinct visual blocks — e.g., title bar + content area + takeaway box, or title + left panel + right panel
Body text area utilization ≥ 50% of the available content space (between title bar at 1.4" and source line at 7.05")
Action Title must be a FULL SENTENCE expressing the slide's key insight:
- ✅ "连接组约束的AI模型将自由参数减少90%，实现单细胞精度预测"
- ❌ "连接组约束的AI模型"
Use specific data points when the user provides them (numbers, percentages, names) — display them prominently with Big Number or Metric Card patterns
Source attribution (add_source()) on every content slide with specific references, not generic labels

Production Guard Rails (v1.9 / v2.0)

These rules address recurring production defects observed across multiple presentation generations. Each rule is derived from real-world user feedback and must be followed without exception.

Rule 1: Spacing Between Content Blocks and Bottom Bars

Problem observed: Tables, charts, or content grids placed immediately above a bottom summary/action bar (e.g., "行动公式", "趋势判读", "风险提示") with zero vertical gap, making them visually merged.

MANDATORY: There MUST be at least 0.15" vertical gap between the last content block and any bottom bar/summary box. Calculate positions explicitly:

# ❌ WRONG: content ends at Inches(6.15), bottom bar also at Inches(6.15)
last_content_bottom = content_top + num_rows * row_height
bar_y = last_content_bottom  # NO GAP!

# ✅ CORRECT: explicit gap
BOTTOM_BAR_GAP = Inches(0.2)
bar_y = last_content_bottom + BOTTOM_BAR_GAP

Validation formula: bottom_bar_y >= last_content_bottom + Inches(0.15)

Rule 2: Content Overflow Protection

Problem observed: Text or shapes extending beyond the right margin (left_margin + content_width) or bottom margin (source line at 7.05").

MANDATORY overflow checks:

Right margin: Every element's left + width ≤ LM + CW (i.e., Inches(0.8) + Inches(11.733) = Inches(12.533))
Bottom margin: Every element's top + height ≤ Inches(6.95) (leaving room for source line at 7.05")
Text in bounded boxes: When placing text inside a colored add_rect() box, the text box MUST be inset by at least 0.15" on each side:

# ✅ CORRECT: text inset within its container box
box_left = LM
box_width = CW
add_rect(s, box_left, box_y, box_width, box_h, BG_GRAY)
add_text(s, box_left + Inches(0.3), box_y, box_width - Inches(0.6), box_h,
         text, ...)  # 0.3" padding on each side

Multi-column layouts: When calculating column widths, account for inter-column gaps AND the right margin:

# total available = CW = Inches(11.733)
num_cols = 3
gap = Inches(0.2)
col_w = (CW - gap * (num_cols - 1)) / num_cols  # NOT CW / num_cols

Long text truncation: If generated text may exceed box boundaries, reduce font_size by 1-2pt or abbreviate text. Never allow visible overflow.

Rule 3: Bottom Whitespace Elimination

Problem observed: Charts or content areas end at ~Inches(5.5) while the bottom bar sits at ~Inches(6.3), leaving ~0.8" of dead whitespace.

MANDATORY: The bottom summary bar should be positioned at no higher than Inches(6.1) and no lower than Inches(6.4). Adjust chart/content heights to fill available space. Target: visible whitespace between content and bottom bar ≤ 0.3".

# ✅ CORRECT: Compute bottom bar position dynamically
content_bottom = chart_top + chart_height
# Place bottom bar close to content (but with minimum gap)
bar_y = max(content_bottom + Inches(0.15), Inches(6.1))
bar_y = min(bar_y, Inches(6.4))  # don't push past safe zone

Rule 4: Legend Color Consistency

Problem observed: Chart legends using plain black text "■" symbols (■ 基准值 ■ 增加 ■ 减少) while actual chart bars use NAVY, ACCENT_RED, ACCENT_GREEN — colors don't match.

MANDATORY: Every legend indicator MUST use a colored square (add_rect()) matching the exact color used in the chart below it. Never use text-only legends with "■" character.

# ❌ WRONG: Text-only legend with black squares
add_text(s, LM, legend_y, CW, Inches(0.25),
         '■ 基准值  ■ 增加  ■ 减少', ...)

# ✅ CORRECT: Color-matched legend squares
lgx = LM + Inches(5)
add_rect(s, lgx, legend_y, Inches(0.15), Inches(0.15), NAVY)
add_text(s, lgx + Inches(0.2), legend_y, Inches(0.9), Inches(0.25),
         '基准值', font_size=Pt(10), font_color=MED_GRAY)
add_rect(s, lgx + Inches(1.3), legend_y, Inches(0.15), Inches(0.15), ACCENT_RED)
add_text(s, lgx + Inches(1.5), legend_y, Inches(0.9), Inches(0.25),
         '增加', font_size=Pt(10), font_color=MED_GRAY)
# ... repeat for each series

Legend placement: Inline with or immediately below the chart subtitle line (typically at Inches(1.15)-Inches(1.20)). Legend squares are 0.15" × 0.15" with 0.05" gap to label text.

Rule 5: Title Style Consistency

Problem observed: Some slides using add_navy_title_bar() (full-width navy background + white text) while others use add_action_title() (white background + black text + underline), creating jarring visual inconsistency.

MANDATORY: Use add_action_title() (aat()) as the ONLY title style for ALL content slides. The navy title bar (antb()) is DEPRECATED for content slides and should only appear if explicitly requested by the user.

# ❌ DEPRECATED: Navy background title bar
def add_navy_title_bar(slide, text):
    add_rect(s, 0, 0, SW, Inches(0.75), NAVY)
    add_text(s, LM, 0, CW, Inches(0.75), text, font_color=WHITE, ...)

# ✅ CORRECT: Consistent white-background action title (bottom-anchored)
def add_action_title(slide, text, title_size=Pt(22)):
    add_text(s, Inches(0.8), Inches(0.15), Inches(11.7), Inches(0.9), text,
             font_size=title_size, font_color=BLACK, bold=True, font_name='Georgia',
             anchor=MSO_ANCHOR.BOTTOM)  # BOTTOM: text sits flush against separator
    add_hline(s, Inches(0.8), Inches(1.05), Inches(11.7), BLACK, Pt(0.5))

Note: When add_action_title() is used, content starts at Inches(1.25) (not Inches(1.0)). Account for this when positioning grids, tables, or charts below the title.

Rule 6: Axis Label Centering in Matrix/Grid Charts

Problem observed: In 2×2 matrix layouts (#13, #59, #65), axis labels ("用户规模↑", "技术壁垒→") positioned at fixed offsets rather than centered on their respective axes, causing visual misalignment.

MANDATORY: Axis labels MUST be centered on the full span of their axis:

# Grid dimensions
grid_left = LM + Inches(2.0)
grid_top = Inches(1.65)
cell_w = Inches(4.5)  # width of each quadrant
cell_h = Inches(2.0)  # height of each quadrant
grid_w = 2 * cell_w   # full grid width
grid_h = 2 * cell_h   # full grid height

# ✅ CORRECT: Y-axis label centered vertically on FULL grid height
add_text(s, LM, grid_top, Inches(1.8), grid_h,
         'Y轴标签↑', alignment=PP_ALIGN.CENTER, anchor=MSO_ANCHOR.MIDDLE)

# ✅ CORRECT: X-axis label centered horizontally on FULL grid width
add_text(s, grid_left, grid_top + grid_h + Inches(0.1), grid_w, Inches(0.3),
         'X轴标签 →', alignment=PP_ALIGN.CENTER)

Rule 7: Image Placeholder Slide Requirement

Problem observed: Presentations generated with zero image-containing slides, resulting in a wall of text/charts that feels monotonous and lacks visual relief.

MANDATORY: For presentations with 8+ slides, at least 1 slide must include image placeholders (using add_image_placeholder() or custom gray boxes with "请插入图片" labels). Preferred positions:

After the first 2-3 content slides (as a visual break)
For case studies, product showcases, or ecosystem overviews

Standard placeholder style (when not using add_image_placeholder() helper):

# Large placeholder
img_l = LM; img_t = Inches(1.3); img_w = Inches(6.5); img_h = Inches(4.0)
add_rect(s, img_l, img_t, img_w, img_h, BG_GRAY)
add_rect(s, img_l + Inches(0.04), img_t + Inches(0.04),
         img_w - Inches(0.08), img_h - Inches(0.08), WHITE)
add_rect(s, img_l + Inches(0.08), img_t + Inches(0.08),
         img_w - Inches(0.16), img_h - Inches(0.16), RGBColor(0xF8, 0xF8, 0xF8))
add_text(s, img_l, img_t + img_h // 2 - Inches(0.3), img_w, Inches(0.5),
         '[ 请插入图片 ]', font_size=Pt(22), font_color=LINE_GRAY,
         bold=True, alignment=PP_ALIGN.CENTER, anchor=MSO_ANCHOR.MIDDLE)
add_text(s, img_l, img_t + img_h // 2 + Inches(0.2), img_w, Inches(0.3),
         '图片描述标签', font_size=Pt(13), font_color=MED_GRAY,
         alignment=PP_ALIGN.CENTER, anchor=MSO_ANCHOR.MIDDLE)

This triple-border style (BG_GRAY → WHITE → #F8F8F8) creates a professional, clearly identifiable placeholder that prompts users to insert real images.

Rule 8: Dynamic Sizing for Variable-Count Layouts (v1.10.4)

Problem observed: Layouts with a variable number of items (checklist rows, value chain stages, cover multi-line titles) use fixed dimensions that only work for a specific count. When item count differs, content either overflows past page boundaries or leaves excessive whitespace.

MANDATORY: For any layout where the number of items is variable, compute dimensions dynamically:

# ✅ Horizontal items (value chain, flow): fill content width
n = len(items)
gap = Inches(0.35)
item_w = (CW - gap * (n - 1)) / n   # NOT a fixed Inches(2.0)

# ✅ Vertical items (checklist, table rows): fit within available height
bottom_limit = BOTTOM_BAR_Y if bottom_bar else SOURCE_Y - Inches(0.05)
available_h = bottom_limit - content_start_y
item_h = min(MAX_ITEM_H, available_h / max(n, 1))  # cap at comfortable max

# ✅ Multi-line titles: height scales with line count
n_lines = text.count('\n') + 1
title_h = Inches(0.8 + 0.65 * max(n_lines - 1, 0))
# Position following elements relative to title bottom, NOT at fixed y

Anti-patterns (❌ NEVER DO):

stage_w = Inches(2.0) for N stages → use (CW - gap*(N-1)) / N
row_h = Inches(0.55) for N rows → use min(0.85, available / N)
subtitle_y = Inches(3.5) on cover → use title_y + title_h + Inches(0.3)

Rule 9: BLOCK_ARC Native Shapes for Circular Charts (v2.0)

Problem observed: Donut charts (#48), pie charts (#64), and gauge dials (#55) rendered with hundreds to thousands of small add_rect() blocks. This creates 100-2800 shapes per chart, inflates file size by 60-80%, slows generation to 2+ minutes, and produces visual artifacts (gaps between blocks, jagged edges).

MANDATORY: Use BLOCK_ARC preset shapes via python-pptx + XML adjustment for all circular/arc charts. Each segment = 1 shape (total: 3-5 shapes per chart vs. hundreds).

BLOCK_ARC angle convention (PPT coordinate system):

Angles measured clockwise from 12 o'clock (top), in 60000ths of a degree
Top = 0°, Right = 90°, Bottom = 180°, Left = 270°
Example: a full-circle donut segment from 12 o'clock CW to 3 o'clock = adj1=0, adj2=5400000

Three adj parameters:

adj1: start angle (60000ths of degree, CW from top)
adj2: end angle (60000ths of degree, CW from top)
adj3: inner radius ratio (0 = solid sector / pie, 50000 = max / invisible ring)

from pptx.oxml.ns import qn

                  ppt_cum % 360, (ppt_cum + sweep) % 360, inner_ratio, color)
    ppt_cum += sweep

Anti-patterns (❌ NEVER DO for circular charts):

Nested for deg in range(...): for r in range(...): add_rect(...) — generates hundreds/thousands of tiny squares
Drawing a white circle on top of a filled circle to "fake" a donut — fragile, misaligns on resize
Using math.cos/sin + add_rect() loops for arcs — always use BLOCK_ARC instead

Mandatory Slide Elements

EVERY content slide (except Cover and Closing) MUST include ALL of these:

Element	Function	Position
Action Title	`add_action_title(slide, text)`	Top (0.15" from top)
Title separator line	Included in `add_action_title()`	1.05" from top
Content area	Layout-specific content blocks	1.4" to 6.5"
Source attribution	`add_source(slide, text)`	7.05" from top
Page number	`add_page_number(slide, n, total)`	Bottom-right corner

Page number helper function:

def add_page_number(slide, num, total):
    add_text(slide, Inches(12.2), Inches(7.1), Inches(1), Inches(0.3),
             f"{num}/{total}", font_size=Pt(9), font_color=MED_GRAY,
             alignment=PP_ALIGN.RIGHT)

Layout Patterns

Slide Dimensions

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 (44pt, Georgia, navy) at y=1.2" — height computed dynamically from line count
Subtitle (24pt, dark gray) positioned below title dynamically
Date/info (14pt, med gray) follows subtitle
Decorative navy line at x=1", y=6.8" (4" wide, 2pt)

Code template:

s1 = prs.slides.add_slide(prs.slide_layouts[6])
add_rect(s1, 0, 0, prs.slide_width, Inches(0.05), NAVY)

# Dynamic title height based on line count
lines = title.split('\n') if isinstance(title, str) else title
n_lines = len(lines) if isinstance(lines, list) else title.count('\n') + 1
title_h = Inches(0.8 + 0.65 * max(n_lines - 1, 0))

add_text(s1, Inches(1), Inches(1.2), Inches(11), title_h,
         '项目名称', font_size=Pt(44), font_name='Georgia',
         font_color=NAVY, bold=True, ea_font='KaiTi')

# Position elements BELOW title dynamically — never use fixed y
sub_y = Inches(1.2) + title_h + Inches(0.3)
add_text(s1, Inches(1), sub_y, Inches(11), Inches(0.8),
         '副标题描述', font_size=Pt(24),
         font_color=DARK_GRAY, ea_font='KaiTi')
sub_y += Inches(1.0)

add_text(s1, Inches(1), sub_y + Inches(0.3), 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_hline(s1, Inches(1), Inches(6.8), Inches(4), NAVY, 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:

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")

# 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:

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))

McKinsey PPT Design Framework

Version: 1.10.4 · License: Apache-2.0 · Author: likaku

Required tools: Read, Write, Bash · Requires: python3, pip

Overview

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

70 layout patterns across 12 categories (structure, data, framework, comparison, narrative, timeline, team, charts, images, advanced viz, dashboards, visual storytelling)
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)
Image placeholder system for image-containing layouts (v1.8)
BLOCK_ARC native shapes for charts — donut, pie, gauge rendered with 3-4 shapes instead of hundreds of blocks, 60-80% smaller files (v2.0)
Production Guard Rails — 9 mandatory rules including spacing/overflow protection, legend color consistency, title style uniformity, axis label centering, dynamic sizing, BLOCK_ARC chart rendering (v1.9+v2.0)
Code Efficiency guidelines — variable reuse patterns, constant extraction, loop optimization for faster generation (v1.9)

All specifications have been refined through iterative production feedback to ensure visual consistency, professional polish, and zero-defect output.

When to Use This Skill

Use this skill when users ask to:

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

Core Design Philosophy

McKinsey Design Principles

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
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
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)
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

Accent Colors (for multi-item differentiation)

Accent Name	Hex	RGB	Paired Light BG	Usage
ACCENT_BLUE	#006BA6	(0, 107, 166)	#E3F2FD	First item accent
ACCENT_GREEN	#007A53	(0, 122, 83)	#E8F5E9	Second item accent
ACCENT_ORANGE	#D46A00	(212, 106, 0)	#FFF3E0	Third item accent
ACCENT_RED	#C62828	(198, 40, 40)	#FFEBEE	Fourth item / warning

Accent Color Rules:

Use accent colors for: card top accent borders (thin 0.06" rect), circle labels (add_oval() bg param), section sub-headers (font_color)
Use paired light BG for: card background fills only
Body text inside cards ALWAYS remains DARK_GRAY (#333333)
NAVY remains the primary color for single-focus elements (one card, one stat, cover title)
Use accent colors ONLY when the slide has 3+ parallel items that need visual distinction
The fourth item (D) can use NAVY instead of ACCENT_RED if red feels inappropriate for the content

# Accent color constants
ACCENT_BLUE   = RGBColor(0x00, 0x6B, 0xA6)
ACCENT_GREEN  = RGBColor(0x00, 0x7A, 0x53)
ACCENT_ORANGE = RGBColor(0xD4, 0x6A, 0x00)
ACCENT_RED    = RGBColor(0xC6, 0x28, 0x28)
LIGHT_BLUE    = RGBColor(0xE3, 0xF2, 0xFD)
LIGHT_GREEN   = RGBColor(0xE8, 0xF5, 0xE9)
LIGHT_ORANGE  = RGBColor(0xFF, 0xF3, 0xE0)
LIGHT_RED     = RGBColor(0xFF, 0xEB, 0xEE)

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:

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

All lines are FLAT - no shadows, no effects, no 3D
Remove theme style references - prevents automatic shadow application
Solid color only - no gradients or patterns
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)

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:

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:

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

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)

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

Presentation Planning

Layout Diversity Requirement

Each content slide MUST use a DIFFERENT layout pattern from its neighbors. Repeating the same layout on consecutive slides makes the presentation feel monotonous and unprofessional.

Match content type to the optimal layout pattern:

Content Type	Recommended Layouts	Avoid
Single key statistic	Big Number (#8)	Plain text
2 options comparison	Side-by-Side (#19), Before/After (#20), Metric Comparison Row (#62)	Two-column text
3-4 parallel concepts	Three-Pillar (#14), Four-Column (#27), Metric Cards (#10), Icon Grid (#63)	Bullet list
Process / steps	Process Chevron (#16), Vertical Steps (#30), Value Chain (#67)	Numbered text
Timeline	Timeline/Roadmap (#29), Cycle (#31)	Bullet list
Data table	Data Table (#9), Scorecard (#22), Harvey Ball Table (#56)	Plain text
Case study	Case Study (#33), Case Study with Image (#45)	Two-column text
Summary / conclusion	Executive Summary (#24), Key Takeaway (#25)	Bullet list
Multiple KPIs	Three-Stat Dashboard (#12), Two-Stat Comparison (#11), KPI Tracker (#52), Dashboard (#57)	Plain text
Time series + values/percentages	Grouped Bar (#37), Stacked Bar (#38), Line Chart (#50), Stacked Area (#70)	Data Table, Scorecard
Category ranking / comparison	Horizontal Bar (#39), Grouped Bar (#37), Pareto (#51)	Bullet list, Plain text
Part-of-whole / composition	Donut (#48), Pie (#64), Stacked Bar (#38)	Bullet list
Content with visual / photo	Content+Right Image (#40), Left Image+Content (#41), Three Images (#42)	Text-only layouts
Risk / evaluation matrix	Risk Matrix (#54), SWOT (#65), Harvey Ball (#56), 2x2 Matrix (#13)	Bullet list
Strategic recommendations	Numbered List+Panel (#69), Decision Tree (#60), Checklist (#61)	Two-column text
Multi-KPI executive dashboard	Dashboard KPI+Chart (#57), Dashboard Table+Chart (#58)	Simple table
Stakeholder / relationship	Stakeholder Map (#59)	Bullet list
Meeting agenda	Agenda (#66)	Plain text

NEVER use Two-Column Text (#26) for more than 1 slide per deck. It is the least visually engaging layout.

Content Density Requirements

"Minimalism" in McKinsey design means removing decorative noise (shadows, gradients, clip-art), NOT removing content. A slide with 80% whitespace is not minimalist — it is EMPTY.

Mandatory minimums per content slide:

At least 3 distinct visual blocks — e.g., title bar + content area + takeaway box, or title + left panel + right panel
Body text area utilization ≥ 50% of the available content space (between title bar at 1.4" and source line at 7.05")
Action Title must be a FULL SENTENCE expressing the slide's key insight:
- ✅ "连接组约束的AI模型将自由参数减少90%，实现单细胞精度预测"
- ❌ "连接组约束的AI模型"
Use specific data points when the user provides them (numbers, percentages, names) — display them prominently with Big Number or Metric Card patterns
Source attribution (add_source()) on every content slide with specific references, not generic labels

Production Guard Rails (v1.9 / v2.0)

These rules address recurring production defects observed across multiple presentation generations. Each rule is derived from real-world user feedback and must be followed without exception.

Rule 1: Spacing Between Content Blocks and Bottom Bars

MANDATORY: There MUST be at least 0.15" vertical gap between the last content block and any bottom bar/summary box. Calculate positions explicitly:

# ❌ WRONG: content ends at Inches(6.15), bottom bar also at Inches(6.15)
last_content_bottom = content_top + num_rows * row_height
bar_y = last_content_bottom  # NO GAP!

# ✅ CORRECT: explicit gap
BOTTOM_BAR_GAP = Inches(0.2)
bar_y = last_content_bottom + BOTTOM_BAR_GAP

Validation formula: bottom_bar_y >= last_content_bottom + Inches(0.15)

Rule 2: Content Overflow Protection

Problem observed: Text or shapes extending beyond the right margin (left_margin + content_width) or bottom margin (source line at 7.05").

MANDATORY overflow checks:

Right margin: Every element's left + width ≤ LM + CW (i.e., Inches(0.8) + Inches(11.733) = Inches(12.533))
Bottom margin: Every element's top + height ≤ Inches(6.95) (leaving room for source line at 7.05")
Text in bounded boxes: When placing text inside a colored add_rect() box, the text box MUST be inset by at least 0.15" on each side:

# ✅ CORRECT: text inset within its container box
box_left = LM
box_width = CW
add_rect(s, box_left, box_y, box_width, box_h, BG_GRAY)
add_text(s, box_left + Inches(0.3), box_y, box_width - Inches(0.6), box_h,
         text, ...)  # 0.3" padding on each side

Multi-column layouts: When calculating column widths, account for inter-column gaps AND the right margin:

# total available = CW = Inches(11.733)
num_cols = 3
gap = Inches(0.2)
col_w = (CW - gap * (num_cols - 1)) / num_cols  # NOT CW / num_cols

Long text truncation: If generated text may exceed box boundaries, reduce font_size by 1-2pt or abbreviate text. Never allow visible overflow.

Rule 3: Bottom Whitespace Elimination

Problem observed: Charts or content areas end at ~Inches(5.5) while the bottom bar sits at ~Inches(6.3), leaving ~0.8" of dead whitespace.

# ✅ CORRECT: Compute bottom bar position dynamically
content_bottom = chart_top + chart_height
# Place bottom bar close to content (but with minimum gap)
bar_y = max(content_bottom + Inches(0.15), Inches(6.1))
bar_y = min(bar_y, Inches(6.4))  # don't push past safe zone

Rule 4: Legend Color Consistency

Problem observed: Chart legends using plain black text "■" symbols (■ 基准值 ■ 增加 ■ 减少) while actual chart bars use NAVY, ACCENT_RED, ACCENT_GREEN — colors don't match.

MANDATORY: Every legend indicator MUST use a colored square (add_rect()) matching the exact color used in the chart below it. Never use text-only legends with "■" character.

# ❌ WRONG: Text-only legend with black squares
add_text(s, LM, legend_y, CW, Inches(0.25),
         '■ 基准值  ■ 增加  ■ 减少', ...)

# ✅ CORRECT: Color-matched legend squares
lgx = LM + Inches(5)
add_rect(s, lgx, legend_y, Inches(0.15), Inches(0.15), NAVY)
add_text(s, lgx + Inches(0.2), legend_y, Inches(0.9), Inches(0.25),
         '基准值', font_size=Pt(10), font_color=MED_GRAY)
add_rect(s, lgx + Inches(1.3), legend_y, Inches(0.15), Inches(0.15), ACCENT_RED)
add_text(s, lgx + Inches(1.5), legend_y, Inches(0.9), Inches(0.25),
         '增加', font_size=Pt(10), font_color=MED_GRAY)
# ... repeat for each series

Legend placement: Inline with or immediately below the chart subtitle line (typically at Inches(1.15)-Inches(1.20)). Legend squares are 0.15" × 0.15" with 0.05" gap to label text.

Rule 5: Title Style Consistency

# ❌ DEPRECATED: Navy background title bar
def add_navy_title_bar(slide, text):
    add_rect(s, 0, 0, SW, Inches(0.75), NAVY)
    add_text(s, LM, 0, CW, Inches(0.75), text, font_color=WHITE, ...)

# ✅ CORRECT: Consistent white-background action title (bottom-anchored)
def add_action_title(slide, text, title_size=Pt(22)):
    add_text(s, Inches(0.8), Inches(0.15), Inches(11.7), Inches(0.9), text,
             font_size=title_size, font_color=BLACK, bold=True, font_name='Georgia',
             anchor=MSO_ANCHOR.BOTTOM)  # BOTTOM: text sits flush against separator
    add_hline(s, Inches(0.8), Inches(1.05), Inches(11.7), BLACK, Pt(0.5))

Note: When add_action_title() is used, content starts at Inches(1.25) (not Inches(1.0)). Account for this when positioning grids, tables, or charts below the title.

Rule 6: Axis Label Centering in Matrix/Grid Charts

MANDATORY: Axis labels MUST be centered on the full span of their axis:

# Grid dimensions
grid_left = LM + Inches(2.0)
grid_top = Inches(1.65)
cell_w = Inches(4.5)  # width of each quadrant
cell_h = Inches(2.0)  # height of each quadrant
grid_w = 2 * cell_w   # full grid width
grid_h = 2 * cell_h   # full grid height

# ✅ CORRECT: Y-axis label centered vertically on FULL grid height
add_text(s, LM, grid_top, Inches(1.8), grid_h,
         'Y轴标签↑', alignment=PP_ALIGN.CENTER, anchor=MSO_ANCHOR.MIDDLE)

# ✅ CORRECT: X-axis label centered horizontally on FULL grid width
add_text(s, grid_left, grid_top + grid_h + Inches(0.1), grid_w, Inches(0.3),
         'X轴标签 →', alignment=PP_ALIGN.CENTER)

Rule 7: Image Placeholder Slide Requirement

Problem observed: Presentations generated with zero image-containing slides, resulting in a wall of text/charts that feels monotonous and lacks visual relief.

After the first 2-3 content slides (as a visual break)
For case studies, product showcases, or ecosystem overviews

Standard placeholder style (when not using add_image_placeholder() helper):

# Large placeholder
img_l = LM; img_t = Inches(1.3); img_w = Inches(6.5); img_h = Inches(4.0)
add_rect(s, img_l, img_t, img_w, img_h, BG_GRAY)
add_rect(s, img_l + Inches(0.04), img_t + Inches(0.04),
         img_w - Inches(0.08), img_h - Inches(0.08), WHITE)
add_rect(s, img_l + Inches(0.08), img_t + Inches(0.08),
         img_w - Inches(0.16), img_h - Inches(0.16), RGBColor(0xF8, 0xF8, 0xF8))
add_text(s, img_l, img_t + img_h // 2 - Inches(0.3), img_w, Inches(0.5),
         '[ 请插入图片 ]', font_size=Pt(22), font_color=LINE_GRAY,
         bold=True, alignment=PP_ALIGN.CENTER, anchor=MSO_ANCHOR.MIDDLE)
add_text(s, img_l, img_t + img_h // 2 + Inches(0.2), img_w, Inches(0.3),
         '图片描述标签', font_size=Pt(13), font_color=MED_GRAY,
         alignment=PP_ALIGN.CENTER, anchor=MSO_ANCHOR.MIDDLE)

This triple-border style (BG_GRAY → WHITE → #F8F8F8) creates a professional, clearly identifiable placeholder that prompts users to insert real images.

Rule 8: Dynamic Sizing for Variable-Count Layouts (v1.10.4)

MANDATORY: For any layout where the number of items is variable, compute dimensions dynamically:

# ✅ Horizontal items (value chain, flow): fill content width
n = len(items)
gap = Inches(0.35)
item_w = (CW - gap * (n - 1)) / n   # NOT a fixed Inches(2.0)

# ✅ Vertical items (checklist, table rows): fit within available height
bottom_limit = BOTTOM_BAR_Y if bottom_bar else SOURCE_Y - Inches(0.05)
available_h = bottom_limit - content_start_y
item_h = min(MAX_ITEM_H, available_h / max(n, 1))  # cap at comfortable max

# ✅ Multi-line titles: height scales with line count
n_lines = text.count('\n') + 1
title_h = Inches(0.8 + 0.65 * max(n_lines - 1, 0))
# Position following elements relative to title bottom, NOT at fixed y

Anti-patterns (❌ NEVER DO):

stage_w = Inches(2.0) for N stages → use (CW - gap*(N-1)) / N
row_h = Inches(0.55) for N rows → use min(0.85, available / N)
subtitle_y = Inches(3.5) on cover → use title_y + title_h + Inches(0.3)

Rule 9: BLOCK_ARC Native Shapes for Circular Charts (v2.0)

MANDATORY: Use BLOCK_ARC preset shapes via python-pptx + XML adjustment for all circular/arc charts. Each segment = 1 shape (total: 3-5 shapes per chart vs. hundreds).

BLOCK_ARC angle convention (PPT coordinate system):

Angles measured clockwise from 12 o'clock (top), in 60000ths of a degree
Top = 0°, Right = 90°, Bottom = 180°, Left = 270°
Example: a full-circle donut segment from 12 o'clock CW to 3 o'clock = adj1=0, adj2=5400000

Three adj parameters:

adj1: start angle (60000ths of degree, CW from top)
adj2: end angle (60000ths of degree, CW from top)
adj3: inner radius ratio (0 = solid sector / pie, 50000 = max / invisible ring)

from pptx.oxml.ns import qn

def add_block_arc(slide, left, top, width, height, start_deg, end_deg, inner_ratio, color):
    """Draw a BLOCK_ARC shape with precise angle and ring-width control.

    Args:
        slide: pptx slide object
        left, top, width, height: bounding box (width == height for circular arc)
        start_deg: start angle in degrees, CW from 12 o'clock (0=top, 90=right, 180=bottom, 270=left)
        end_deg: end angle in degrees, CW from 12 o'clock
        inner_ratio: 0 = solid pie sector, 50000 = max (paper-thin ring).
                     For ~10px ring width: int((outer_r - Pt(10)) / outer_r * 50000)
        color: RGBColor fill color
    """
    from pptx.enum.shapes import MSO_SHAPE
    sh = slide.shapes.add_shape(MSO_SHAPE.BLOCK_ARC, left, top, width, height)
    sh.fill.solid()
    sh.fill.fore_color.rgb = color
    sh.line.fill.background()
    _clean_shape(sh)  # remove p:style to prevent file corruption

    sp = sh._element.find(qn('p:spPr'))
    prstGeom = sp.find(qn('a:prstGeom'))
    if prstGeom is not None:
        avLst = prstGeom.find(qn('a:avLst'))
        if avLst is None:
            avLst = prstGeom.makeelement(qn('a:avLst'), {})
            prstGeom.append(avLst)
        for gd in avLst.findall(qn('a:gd')):
            avLst.remove(gd)
        gd1 = avLst.makeelement(qn('a:gd'), {'name': 'adj1', 'fmla': f'val {int(start_deg * 60000)}'})
        gd2 = avLst.makeelement(qn('a:gd'), {'name': 'adj2', 'fmla': f'val {int(end_deg * 60000)}'})
        gd3 = avLst.makeelement(qn('a:gd'), {'name': 'adj3', 'fmla': f'val {inner_ratio}'})
        avLst.append(gd1)
        avLst.append(gd2)
        avLst.append(gd3)
    return sh

Usage patterns:

# ── Donut chart: 4 segments, ~10px ring width ──
outer_r = Inches(1.6)
inner_ratio = int((outer_r - Pt(10)) / outer_r * 50000)  # ~10px ring
cum_deg = 0  # start at top (0° = 12 o'clock)
for pct, color, label in segments:
    sweep = pct * 360
    add_block_arc(s, cx - outer_r, cy - outer_r, outer_r * 2, outer_r * 2,
                  cum_deg, cum_deg + sweep, inner_ratio, color)
    cum_deg += sweep

# ── Pie chart (solid sectors): inner_ratio = 0 ──
add_block_arc(s, cx - r, cy - r, r * 2, r * 2, 0, 151.2, 0, NAVY)  # 42%

# ── Horizontal rainbow gauge (semi-circle, left→top→right) ──
# PPT coords: left=270°, top=0°, right=90°
gauge_segs = [(0.40, ACCENT_RED), (0.30, ACCENT_ORANGE), (0.30, ACCENT_GREEN)]
inner_ratio = int((outer_r - Pt(10)) / outer_r * 50000)
ppt_cum = 270  # start at left
for pct, color in gauge_segs:
    sweep = pct * 180
    add_block_arc(s, cx - outer_r, cy - outer_r, outer_r * 2, outer_r * 2,
                  ppt_cum % 360, (ppt_cum + sweep) % 360, inner_ratio, color)
    ppt_cum += sweep

Anti-patterns (❌ NEVER DO for circular charts):

Nested for deg in range(...): for r in range(...): add_rect(...) — generates hundreds/thousands of tiny squares
Drawing a white circle on top of a filled circle to "fake" a donut — fragile, misaligns on resize
Using math.cos/sin + add_rect() loops for arcs — always use BLOCK_ARC instead

Mandatory Slide Elements

EVERY content slide (except Cover and Closing) MUST include ALL of these:

Element	Function	Position
Action Title	`add_action_title(slide, text)`	Top (0.15" from top)
Title separator line	Included in `add_action_title()`	1.05" from top
Content area	Layout-specific content blocks	1.4" to 6.5"
Source attribution	`add_source(slide, text)`	7.05" from top
Page number	`add_page_number(slide, n, total)`	Bottom-right corner

Page number helper function:

def add_page_number(slide, num, total):
    add_text(slide, Inches(12.2), Inches(7.1), Inches(1), Inches(0.3),
             f"{num}/{total}", font_size=Pt(9), font_color=MED_GRAY,
             alignment=PP_ALIGN.RIGHT)

Layout Patterns

Slide Dimensions

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 (44pt, Georgia, navy) at y=1.2" — height computed dynamically from line count
Subtitle (24pt, dark gray) positioned below title dynamically
Date/info (14pt, med gray) follows subtitle
Decorative navy line at x=1", y=6.8" (4" wide, 2pt)

Code template:

s1 = prs.slides.add_slide(prs.slide_layouts[6])
add_rect(s1, 0, 0, prs.slide_width, Inches(0.05), NAVY)

# Dynamic title height based on line count
lines = title.split('\n') if isinstance(title, str) else title
n_lines = len(lines) if isinstance(lines, list) else title.count('\n') + 1
title_h = Inches(0.8 + 0.65 * max(n_lines - 1, 0))

add_text(s1, Inches(1), Inches(1.2), Inches(11), title_h,
         '项目名称', font_size=Pt(44), font_name='Georgia',
         font_color=NAVY, bold=True, ea_font='KaiTi')

# Position elements BELOW title dynamically — never use fixed y
sub_y = Inches(1.2) + title_h + Inches(0.3)
add_text(s1, Inches(1), sub_y, Inches(11), Inches(0.8),
         '副标题描述', font_size=Pt(24),
         font_color=DARK_GRAY, ea_font='KaiTi')
sub_y += Inches(1.0)

add_text(s1, Inches(1), sub_y + Inches(0.3), 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_hline(s1, Inches(1), Inches(6.8), Inches(4), NAVY, 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:

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")

# 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:

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))
