HTML Presentation Beautifier

Transform documents and data into professional McKinsey-style HTML presentations with AI-powered content structuring, intelligent visualization, and automatic quality review.

Core Principle: Preserve 100% of original content while applying professional McKinsey-style design.

Presentation Design Philosophy

Before creating any presentation, consider:

• Audience: Who will see this? (determines complexity and formality)
• Core Message: What's the single most important takeaway?
• Story Arc: How do slides build towards the conclusion?
• Visual Hierarchy: Which data and insights deserve emphasis?

Key Principle: Better to have 20 clear slides than 10 cluttered ones. Content preservation is non-negotiable.

When to Use This Skill

Trigger scenarios:

• "Create a presentation from this document/report"
• "Transform this analysis into slides"
• "Generate McKinsey-style presentation"
• "Visualize this data professionally"
• "Make HTML slides from this content"

Process Overview

6-phase AI-powered workflow using subagents:

Total: ~10-12 minutes for typical presentation

Phase 1: Document Parsing

Goal: Extract structure, data, and conclusions without modification.

Steps:

1. Read source document completely
2. Identify document type (report, analysis, research)
3. Extract structural elements:

- Headings and subheadings - Bullet points and lists - Data tables and numerical data - Key conclusions and recommendations

1. Map content hierarchy: main topics → subtopics → details
2. Identify quantitative data suitable for charts

Exit Criteria: Document fully parsed with content structure mapped.

Phase 2: Content Structuring (Using Subagent)

Goal: Transform parsed content into slide-friendly structure.

Approach: Use Task tool with general-purpose subagent.

MANDATORY - READ ENTIRE FILE: Before invoking subagent, read subagent-prompts.md for the Phase 2 prompt template.

Subagent Task:

• Input: Parsed document content
• Output: JSON slide plan with slide types, titles, content, visualization assignments
• Critical: Preserve 100% of content, assign visualizations to all insights/conclusions

Slide Types:

• TITLE: Cover slide
• TOC: Table of contents (if 10+ slides)
• DATA_VISUALIZATION: Slides with numerical data
• CONCEPTUAL: Framework slides (SWOT, timeline, etc.)
• CONTENT: General content slides
• CONCLUSIONS: Key findings with visualizations
• INSIGHTS: Recommendations with visualizations
• END: Thank you slide

Exit Criteria: Structured slide plan with all slides defined, zero content loss.

Phase 3: Design & Layout

Goal: Apply McKinsey-style design system.

MANDATORY - READ ENTIRE FILE: Read mckinsey-design-system.md for complete design specifications.

Additional References:

• assets/LAYOUTS_INDEX.md - Layout type index with structure examples and configuration parameters
• assets/layouts/*.html - Actual layout example files for reference

Do NOT load other reference files for this phase.

Key Actions:

1. Select appropriate layout for each slide type
2. Apply McKinsey color palette (#F85d42, #556EE6, #34c38f, etc.)
3. Set typography hierarchy (titles 48-64px, subtitles 28-36px, body 16-20px)
4. Optimize spacing (40-60px padding, 20-30px element spacing)
5. Ensure responsive design (1200px, 768px, mobile breakpoints)

Exit Criteria: All slides designed with consistent McKinsey-style branding.

Phase 3.5: Content Visualization Beautification (Using Subagent)

Goal: Beautify content with appropriate charts and graphics, avoiding pure text lists.

Approach: Use Task tool with general-purpose subagent.

MANDATORY - READ ENTIRE FILE: Read chart-selection-guide.md for complete visualization decision trees.

Additional References:

• assets/COMPONENTS_INDEX.md - Complete component index with CSS classes, Chart.js configurations, and component selection decision tree
• assets/components/*.html - Actual component example files for reference

Do NOT load other reference files for this phase.

Subagent Task:

• Input: Structured slide plan from Phase 2
• Output: Enhanced slide plan with specific visualization types assigned
• Process: Analyze content structure → Match to visualization type → Reference example files

9 Content Structure Types:

1. Progressive (递进型) → progression, timeline, flowchart
2. Temporal (时间序列型) → timeline, strategy-roadmap
3. Parallel (并列型) → emphasis-box, mindmap, matrix
4. Hierarchical (层级型) → pyramid, inverted-pyramid
5. Comparative (对比型) → comparison, pros-cons, venn-diagram
6. Framework (分析框架型) → swot, ansoff, 5w1h, competitive-4box
7. Transformation (转化流程型) → funnel, value-stream
8. Cyclical (循环型) → cycle, circular-flow
9. Causal (因果型) → problem-solution, pareto, gauge

Example Files Location: assets/components/*.html and assets/layouts/*.html (e.g., flowchart-example.html, pyramid-chart-example.html)

Exit Criteria: All content slides enhanced with appropriate visualizations, no plain text bullet lists for insights.

Phase 4: HTML Generation (Using Subagent)

Goal: Generate single-file, self-contained HTML presentation.

Approach: Use Task tool with general-purpose subagent executing 4 sub-steps.

MANDATORY - READ ENTIRE FILE: Read template-guide.md for complete template usage instructions.

Additional References:

• assets/INDEX.md - Master index with directory structure and quick start guide
• assets/LAYOUTS_INDEX.md - Layout type index with structure examples and configuration parameters
• assets/layout-template.html - Layout template with single/double/triple column and card grid examples
• assets/component-template.html - Component template with chart and diagram examples

MANDATORY - READ ENTIRE FILE: Read subagent-prompts.md for the Phase 4 prompt template.

Do NOT load other reference files for this phase.

4-Step Process:

Step 4.1: Template Selection

• Slide #1 → templates/cover-slide-template.html
• Slide #2 → templates/toc-slide-template.html (if 10+ slides)
• Slides #3-#N-1 → templates/content-slide-template.html
• Slide #N → templates/end-slide-template.html

NOTE: Also reference assets/layouts/ for additional layout examples and assets/LAYOUTS_INDEX.md for layout selection guidance.

Step 4.2: Content Analysis & Chart Selection

• For DATA_VISUALIZATION slides: Use chart_type field (bar, line, pie, doughnut, radar, polarArea, bubble, scatter)
• For other slides: Use visualization_type field (pyramid, timeline, flowchart, mindmap, etc.)
• Copy CSS and HTML from corresponding assets/components/*.html and assets/layouts/*.html example files
• IMPORTANT: Reference assets/COMPONENTS_INDEX.md for chart component details and assets/LAYOUTS_INDEX.md for layout configurations

Additional Optimization Tips:

• Use assets/layout-template.html as a reference for layout structure
• Use assets/component-template.html as a reference for component structure
• All charts must use 100% width within their containers
• Charts on chart pages must use 2-column or 3-column layouts (never single column)

Step 4.3: Apply Optimization

• Integrate template structure with content
• Apply McKinsey design system (exact colors, fonts, layouts)
• Insert exact text from slide plan (preserve data precision: 1723.498, not 1723.5)
• Initialize Chart.js charts with McKinsey colors
• Implement conceptual visualizations from assets/

Step 4.4: HTML File Output

• Assemble complete single-file HTML
• All CSS inline in <style> tag
• All JavaScript inline in <script> tag
• Include Chart.js CDN: https://cdn.jsdelivr.net/npm/chart.js
• Save to: {original_filename}_beautified.html

Exit Criteria: Complete HTML presentation file generated, ready to open in browser.

Phase 5: Review & Verify (Using Subagent)

Goal: Automatically review generated HTML for quality, integrity, and compliance.

Approach: Use Task tool with html-presentation-reviewer agent from ./agents/html-presentation-reviewer.md.

Invocation:

Use Task tool to call html-presentation-reviewer agent with:
- Generated HTML file path
- Source document path
- Request comprehensive review report

Review Dimensions:

1. Content Integrity (CRITICAL) - 100% preservation verification
2. Code Quality - HTML/CSS/JS validity
3. McKinsey Style Compliance - Design standards check
4. Chart Validity - Visualization correctness
5. Interactivity - Feature testing

Score Interpretation:

• Score ≥85: Approved, optional improvements
• Score 75-84: Acceptable, address major issues
• Score <75: Needs regeneration

Exit Criteria: HTML presentation reviewed and approved with detailed report.

Interactive Features

Generated presentations include:

• Navigation: Previous/Next buttons, slide counter, arrow keys (←/→), Space (next)
• Fullscreen: Toggle button, Escape to exit
• Keyboard Shortcuts: Home (first slide), End (last slide)
• Responsive Design: Desktop, tablet, mobile layouts
• Chart Interactivity: Hover tooltips, legend toggling

NEVER Do These

Content Integrity:

• NEVER modify original content or conclusions - preserve 100%
• NEVER delete, skip, or omit any content
• NEVER summarize or compress - show complete detail
• NEVER truncate lists - if source has 15 items, show all 15
• NEVER paraphrase - use exact wording from source
• NEVER add fabricated data - only use source data

Design Standards:

• NEVER deviate from McKinsey color scheme (#F85d42, #556EE6, #34c38f, #50a5f1, #f1b44c, #74788d)
• NEVER use inconsistent typography - maintain hierarchy
• NEVER present conclusions/insights as plain text bullet lists - always visualize
• NEVER use generic AI aesthetics (purple gradients, Inter font, default border-radius)

Quality:

• NEVER sacrifice content for aesthetics - better 20 dense slides than 10 incomplete ones
• NEVER skip Phase 5 review - quality verification is mandatory

Content Integrity Verification (MANDATORY)

Before finalizing presentation, verify 100% content preservation:

Checklist:

• Section counts match (source vs presentation)
• Bullet point counts match
• Data point counts match
• Conclusion counts match
• Exact wording preserved (no paraphrasing)

IF ANY COUNT DOES NOT MATCH, REGENERATE.

Red Flags:

• "Key points" instead of complete lists
• Charts showing only "top N items"
• Bullet counts that don't match source
• Phrasing that doesn't match source exactly
