Overview

This skill produces professional McKinsey consulting-style HTML slide decks. Every presentation is data-driven, information-dense, and visually rigorous. The workflow covers end-to-end generation: research → planning → slide creation (cover, content, section dividers, TOC, summary) → deployment. All slides are rendered as static HTML with inline SVG charts — no generated images except in rare, data-driven cases.

---

Workflow (MANDATORY ORDER — No Skipping Steps)

Step 1: Research Phase (CRITICAL — DO FIRST)

NEVER skip this step. Data quality determines presentation quality.

Gather comprehensive data before any slide creation:

Research Objectives

• Market size, CAGR, growth rates
• Company metrics and milestones
• Competitor analysis and market share
• Historical trend data for charts
• Verified statistics with source citations

Information Source Prioritization

Tier	Source Type	Examples
1	Official Data/APIs	Company filings, government databases, central banks
2	Research Institutions	McKinsey, BCG, Goldman Sachs, Morgan Stanley, IMF, World Bank
3	Industry Reports	Gartner, Statista, CB Insights, PitchBook
4	News Organizations	Reuters, Bloomberg, Financial Times
5	Company Websites	Official press releases, investor relations

Search Strategy

Execute multiple targeted searches:

• "[Topic] market size 2025"
• "[Topic] industry report"
• "[Company] revenue growth 2025"
• "[Topic] competitors market share"
• "[Topic] trends forecast 2026"
• "[Company] founding history milestones"
• "[Topic] CAGR growth rate"
• "[Topic] regional breakdown"

Data Quality Requirements

For every piece of data collected, record:

• The specific data point (number, percentage, fact)
• The source name (organization)
• The publication date or data date
• The original URL

MANDATORY minimums before completing research:

• [ ] At least 15 specific statistics/data points
• [ ] At least 5 different sources
• [ ] Data for each planned content slide
• [ ] Historical trend data for at least 1 chart
• [ ] Competitor comparison data
• [ ] Proper source citations in PPT format

AVOID:

• ❌ Unsourced claims
• ❌ Outdated data (>2 years old for fast-moving industries)
• ❌ Vague qualitative statements ("significant growth")
• ❌ Single-source critical facts

Step 2: Presentation Planning

Based on research findings, plan the slide structure:

• Default: 10 slides (unless user specifies otherwise)
• Recommended structure: Cover → Content Pages → Summary
• Section dividers are OPTIONAL — only include if content naturally divides into distinct sections
• For most presentations, a simple Cover + Content + Summary structure is preferred

Typical 10-slide structure:

• Slide 1: Cover page
• Slides 2–9: Content pages with data visualizations
• Slide 10: Summary/Conclusion

Step 3: Generate Cover Page

• NO generated images allowed
• NO graphical elements (shapes, icons, decorations)
• Use solid colors OR subtle gradients ONLY
• Centered typography is the PRIMARY visual element
• Elegant, restrained, professional

See Cover Page Specifications below.

Step 4: Generate Content Pages

For each content slide:

• Minimum 4 distinct content zones per page
• White background is MANDATORY default (80%+ of slides)
• SVG charts only — no generated images
• Include source citations in footer

See Content Page Specifications below.

Step 5: Generate Optional Pages

If needed, generate:

• Table of Contents (see TOC Specifications)
• Section Dividers (see Section Divider Specifications)
• Summary/Closing Page (see Summary Page Specifications)

Step 6: Deployment

Deploy the completed presentation using deploy_html_presentation.

Design System

Core Design Philosophy

Professional & Serious: All presentations must be square, formal, and business-appropriate. This is a consulting deck, NOT a creative portfolio.

Data-Driven: Every content slide must be backed by verifiable data with proper source citations.

Information Density: Content pages should maximize information density with at least 4 distinct content zones per slide.

Style: Sharp & Compact — square corners, high information density, professional severity. border-radius: 0 on ALL elements.

Color System

Primary Colors

Element	Color Name	Hex	Usage
Main Background	White	#FFFFFF	Primary slide background (MANDATORY DEFAULT)
Title Bar/Header	Deep Navy Blue	#0B1F3A	Top header bar (0.6" height)
Primary Accent	Cobalt Blue	#1B5AB5	Primary chart series, emphasis elements, insight text
Body Text/Labels	Dark Gray	#2D2D2D	Primary body text, data labels
Secondary Text/Footnotes	Medium Gray	#8C8C8C	Secondary text, footnotes, sources
Grid Lines/Dividers	Light Gray	#E0E0E0	Chart grid lines, separators

Cover Page & Section Divider Background Colors (Choose ONE)

Option	Hex Code	Effect	Text Color
White	#FFFFFF	Clean, minimal, modern	Navy #0B1F3A
Navy Blue	#0B1F3A	Professional, authoritative	White #FFFFFF
Cobalt Blue	#1B5AB5	Bold, confident	White #FFFFFF
Cyan	#2E8BC0	Fresh, innovative	White #FFFFFF
Emerald Green	#3AAF6C	Growth, sustainability	White #FFFFFF
Gray	#4A4A4A	Neutral, sophisticated	White #FFFFFF

Gradient Options (Cover/Divider pages ONLY, subtle only)

Gradient	CSS Example
Navy to Dark	background: linear-gradient(180deg, #0B1F3A 0%, #1B3A5C 100%);
Blue to Navy	background: linear-gradient(180deg, #1B5AB5 0%, #0B1F3A 100%);

Note: Gradients are ONLY allowed on cover pages and section dividers. Content pages MUST NOT use gradients.

Chart Data Series Colors (use in order)

Series	Color Name	Hex
1	Cobalt Blue	#1B5AB5
2	Cyan Blue	#2E8BC0
3	Amber Gold	#D4A843
4	Coral Red	#E05252
5	Emerald Green	#3AAF6C
6	Purple Gray	#7B6D9E

Semantic Colors

Purpose	Color	Hex
Positive Data	Green	#3AAF6C
Negative Data	Red	#E05252

⚠️ Accent Color Limit (STRICTLY ENFORCED — MAX 2 PER PAGE)

RULE: Maximum 2 accent colors per page. This is NON-NEGOTIABLE.

Type	Colors	Can Use Freely
Base Colors	Navy #0B1F3A, White #FFFFFF, Grays (#2D2D2D, #8C8C8C, #E0E0E0)	✅ Yes
Primary Accent	Cobalt Blue #1B5AB5	✅ Always allowed
Secondary Accent	#2E8BC0, #D4A843, #E05252, #3AAF6C, #7B6D9E	⚠️ Pick ONLY ONE

Enforcement:

• Before writing HTML: Decide which 2 accent colors you will use
• During HTML writing: Only use those 2 colors for accents
• During verification: Count accent colors — if >2, FIX by replacing extras with #1B5AB5 or #E0E0E0

ONLY EXCEPTION: Multi-series charts with 3+ distinct data categories may use additional colors within that single chart.

• Light gray grid lines (#E0E0E0)
• Y-axis starts from zero (unless specifically noted)
• Data labels directly on charts to reduce legend lookup cost
• Legend position: Below chart or right side, 9px font
• Square corners on ALL bars — NO rx/ry attributes

Bar/Column Chart

• Corner radius: 0 (SQUARE corners — NO rounded edges)
• Bar width ratio: 70% of available space
• Use chart series colors in order
• NO rx/ry attributes on rect elements

Pie Charts — Image Generation Tool is MANDATORY

Pie charts MUST be created using the image generation tool. SVG pie charts require arc commands (A) which are forbidden for PPTX conversion. ALL workarounds (layered circles, stroke-dasharray, clip-paths, conic-gradient, rotated segments) WILL FAIL during PPTX conversion.

---

HTML Implementation Specification

Appendix A — Responsive Scaling Snippet (REQUIRED)

Every slide HTML file MUST include this snippet:

Appendix B — CSS Rules (REQUIRED)

⚠️ Inline-Only CSS

All CSS styles MUST be inline (except the snippet in Appendix A).

• Do NOT use

  ⚠️ Background on .slide-content Directly

  Do NOT create a full-size background DIV inside .slide-content. Set background directly on .slide-content itself.

  
  
    
  Title
  
  
    
  
  
  

  ⚠️ No Bold for Body Text and Captions

  Reserve bold (font-weight: 600+) for titles, headings, and key emphasis only. Body text, captions, legends, and footnotes must use normal weight (400–500).

  Appendix C — Color Palette Rules (REQUIRED)

  • Strictly use the provided color palette. Do NOT create or modify color values.
  • Only exception: You may add opacity to palette colors for overlays (e.g., rgba(r,g,b,0.1))
  • No gradients on content pages — No CSS linear-gradient(), radial-gradient(), conic-gradient() on content slides
  • No animations — No CSS animation, @keyframes, transition, hover effects, or SVG

  Appendix D — SVG Conversion Constraints (CRITICAL)

  Supported SVG Elements (WHITELIST)

  • ✅ — rectangles (with rx/ry for rounded corners)
  • ✅ — circles
  • ✅ — ellipses
  • ✅ — straight lines
  • ✅ — connected line segments (stroke only, NO fill)
  • ✅ — closed polyline (stroke only, NO fill)
  • ✅ — ONLY with M/L/H/V/Z commands
  • ✅ — repeating patterns

  Command Restrictions (CRITICAL)

  ONLY these commands are supported:

  • ✅ M/m — moveTo
  • ✅ L/l — lineTo
  • ✅ H/h — horizontal line
  • ✅ V/v — vertical line
  • ✅ Z/z — close path

  FORBIDDEN commands (will cause SVG to be SKIPPED in PPTX):

  • ❌ Q/q — quadratic Bézier curve
  • ❌ C/c — cubic Bézier curve
  • ❌ S/s — smooth cubic Bézier
  • ❌ T/t — smooth quadratic Bézier
  • ❌ A/a — elliptical arc

  Additional SVG Constraints

  • ❌ NO rotated shapes — transform="rotate()" on shapes causes fallback failure
  • ❌ NO in complex SVGs — SVG text becomes rasterized, not editable in PPTX
  • ❌ Filled must be rectangles — if a path has fill, it must form a closed rectangle with only M/L/H/V/Z
  • ⚠️ Gradients in SVG are DISCOURAGED — technically supported but can break

  Workaround: Approximate Curves with Line Segments

  Appendix E — Advanced SVG Techniques

  • SVG is for decorative elements ONLY — it does NOT satisfy "real image" requirements
  • Prefer SVG for all decorative shapes (lines/dividers, corner accents, badges, frames, arrows)
  • Use SVG when pixel-crisp geometry is needed under transform: scale()
  • Background shapes MUST use SVG or , NOT CSS background/border
  • Dividers MUST use SVG, NOT CSS background, border, or

    LABEL
  
  

  SVG Background Patterns

  SVG Icons (Supported Patterns)

  SVG Implementation Tips

  • Add vector-effect="non-scaling-stroke" to keep stroke widths stable under scaling
  • For thin lines, prefer filled rectangles over stroked lines
  • Use overflow="visible" when SVG extends beyond its box
  • Use aria-hidden="true" for decorative SVGs
  • Use currentColor for easy theming
  • Use pointer-events: none for overlay SVGs

  Appendix F — HTML2PPTX Validation Rules (REQUIRED)

  Layout and Dimensions

  • Slide content must not overflow the body (no scroll)
  • Text elements larger than 12pt must be at least 0.5" above the bottom edge
  • HTML body dimensions must match presentation layout size

  Backgrounds and Images

  • Do NOT use CSS gradients
  • Do NOT use background-image on div elements
  • For slide backgrounds, use a real element as background
  • Solid background colors on a dedicated shape/div element

  Text Elements

  • p, h1–h6, ul, ol, li must NOT have background, border, or shadow
  • Inline elements (span, b, i, u, strong, em) must NOT have margins
  • Do NOT use manual bullet symbols — use
    or
    lists
    1. Do NOT leave raw text directly inside div — wrap in text tags

    SVG and Text

    • Do NOT place text (,

      ) as overlay on SVG — it will be lost in PPTX

    • Text on SVG shapes must use element inside the SVG
    • SVG must use text-anchor="middle" and dominant-baseline="central"

    Placeholders

    • Elements with class placeholder must have non-zero width and height

    Appendix G — Page Number Badge (REQUIRED)

    All slides except Cover Page MUST include a page number badge. Shows current slide number in bottom-right corner.

    • Position: position:absolute; right:32px; bottom:24px;
    • Must use SVG (text inside , not overlaid )
    • Colors from palette only; keep it subtle; same style across all slides
    • Show current number only (e.g. 3 or 03), not "3/12"

    
    
    
    03

    No Excessive Whitespace (MANDATORY CHECK)

    Every page must be information-dense. Avoid large empty areas.

    Check	Requirement
    Content Coverage	At least 70% of the content area must contain meaningful content
    Gap Size	No single empty gap larger than 1" (52px) in any direction
    Zone Balance	All 4+ zones should have substantial content, not filler

    During page verification, check for:
    • Large empty margins between zones
    • Sparse content zones (single bullet point only)
    • Unbalanced layouts (one zone full, others empty)
    • Content that could be expanded to fill space

    Slide Page Type Classification

    Classify every slide as exactly one of these 5 page types:

    • Cover Page — Opening + tone setting
    • Table of Contents — Navigation + expectation setting (3–5 sections)
    • Section Divider — Clear transitions between major parts
    • Content Page — Data-rich slides (pick a subtype)
    • Summary / Closing Page — Wrap-up + action

    Common Mistakes to Avoid

    • Don't repeat the same layout — vary columns, cards, and callouts across slides
    • Don't center body text — left-align paragraphs and lists; center only titles
    • Don't skimp on size contrast — titles need clear differentiation from body text
    • Don't use colors outside the palette — strictly use provided color values
    • Don't mix spacing randomly — choose consistent gaps
    • Don't create text-only slides — add charts, data tables, or visual elements
    • Don't forget text box padding — account for padding when aligning shapes with text
    • Don't use low-contrast elements — icons AND text need strong contrast against background
    • NEVER use accent lines under titles — hallmark of AI-generated slides; use whitespace instead
    • NEVER use rounded corners — all elements must have border-radius: 0
    • NEVER skip source citations — every data slide needs a footer citation
    • NEVER exceed 2 accent colors per page (except multi-series charts)
    • NEVER use generated images for decoration — SVG charts only

    Verification Workflow (MANDATORY for Every Slide)

    After generating each slide's HTML, verify using screenshots:

    • Layout Structure: Correct header/insight/content/footer zones
    • Text Overflow/Truncation: No text cut off, no "..." truncation
    • Whitespace: No large empty gaps, 70%+ fill rate, check right side and bottom
    • Accent Colors: Count ≤2 (excluding base colors)
    • Content Variety: Not all bullet points
    • Square Corners: No border-radius anywhere
    • Source Citation: Footer citation present on data slides
    • Page Number Badge: Present on all non-cover slides

    If ANY issue is found, FIX immediately before proceeding to the next slide.
