Beamer Slides from Documents

Shared narrative rules

Load the writer skill's references/common/writing.md when slide prose explains source material. Slides should present the content and its evidence, not the agent's search process or defensive disclaimers.

Overview

Create LaTeX Beamer presentation slides by converting structured document content into academic-style slides. Focus on preserving the original document's narrative and structure while ensuring proper page layout and academic presentation standards.

When to Use

Use when:

• Converting academic papers, technical reports, or structured documents into presentation slides
• Source document has clear hierarchical structure (sections, subsections, headers)
• Need to maintain original document's narrative flow and terminology
• Creating academic or technical presentations requiring formal structure
• Document contains mathematical formulas, figures, tables that need proper formatting

Don't use when:

• Creating highly visual or creative presentations (consider other tools)
• Source material lacks structure or is unorganized text
• Need minimal slide decks (3-5 slides) - manually create instead

Core Pattern: Structure Preservation

Document Structure Mapping

Map document hierarchy to slide structure:

Document Title        → Title slide
Main sections (##)     → New sections with table of contents
Subsections (###)     → Individual frames
Content within         → Frame content (bullet points, math, figures)

Section Processing Logic

% Main section in document → Beamer section
\section{Section Title}

% Subsection content → Individual frame
\begin{frame}
  \frametitle{Subsection Title}
  [Content from document]
\end{frame}

Automatic Table of Contents

Generate TOC slides at beginning of each section:

\AtBeginSection[]
{
  \begin{frame}
    \frametitle{内容提要}
    \tableofcontents[currentsection]
  \end{frame}
}

Content Conversion Rules

1. Narrative Preservation (CRITICAL)

Use original document's exact wording and structure:

• Copy text directly from source document
• Preserve original terminology and expressions
• Maintain document's logical flow
• Keep original emphasis (bold, italics) where meaningful

What to preserve:

• Original definitions and explanations
• Mathematical formulas and derivations
• Author's original examples and illustrations
• Paper's conclusions and contributions

What to adapt:

• Long paragraphs → bullet points or shorter sentences
• Complex sentence structures → clearer academic Chinese
• Very long sections → multiple frames

Examples:

% ❌ BAD: Rewording original content
\textbf{QTurbo的核心优势}在于方程系统优化

% ✅ GOOD: Using original wording
\textbf{QTurbo的工作流程}：首先，QTurbo通过将全局混合方程系统分解为全局线性方程系统和多个局部混合方程系统...

2. Academic Style Requirements

Language and tone:

• Use formal academic Chinese (学术汉语)
• Avoid colloquial expressions (口语化表达)
• Maintain professional terminology
• Use precise technical language

Prohibited patterns:

• ❌ "核心"、"关键"、"重要"等过度强调词语
• ❌ "不是...而是..."的重复句式
• ❌ 段落开头使用粗写短语+冒号（如"核心："）

Better alternatives:

• Use specific descriptive terms: "设计原理"、"主要优势"、"显著进展"
• Vary sentence structure to avoid monotony
• Integrate emphasis naturally into full sentences

Reader-Relevance Filter

Keep slide text focused on the claims, evidence, definitions, relationships, and conclusions the audience needs. Remove meta-commentary about the author's process or intent, including statements about preserving fidelity, explaining why wording was chosen, or avoiding speculation. Mention a source limitation only when it changes the claim shown on the slide.

3. Chinese Quote Marks (CRITICAL for Chinese Documents)

When writing Chinese text in LaTeX Beamer (with ctex package), ALWAYS use proper quote marks:

Chinese Double Quotes:

• Left double quote: `` (two backticks)
• Right double quote: '' (two single quotes/apostrophes)

Chinese Single Quotes:

• Left single quote: ` (one backtick)
• Right single quote: ' (one single quote/apostrophe)

How to type:

• Press backtick key (`) twice for left double quote: ``
• Press apostrophe key (') twice for right double quote: ''
• Press backtick key once for left single quote: `
• Press apostrophe key once for right single quote: '

Examples:

% ✅ CORRECT - Chinese quotes
这是一个``简单''的定义
这个概念称为``接近性''和``连续性''

% ❌ INCORRECT - ASCII straight quotes (ugly in PDF)
这是一个"简单"的定义
这个概念称为"接近性"和"连续性"

IMPORTANT: Always use and '' for quotes in Chinese text, never use ", corner brackets, or any other form!

4. Layout and Formatting

Image sizing guidelines:

• Use keepaspectratio to prevent distortion
• Adjust size based on content and layout needs
• Test compile to ensure proper display

Image examples:

% Full-width images
\includegraphics[width=0.85\textwidth,height=0.45\textheight,keepaspectratio]{figure.jpg}

% Column images
\includegraphics[width=\textwidth,height=0.4\textheight,keepaspectratio]{figure.jpg}

Text layout guidelines:

• Use vertical spacing (\vspace{}) as needed for content separation
• Ensure content fits within frame boundaries
• Use columns for side-by-side content
• Split long sections across multiple frames

Column layout pattern:

\begin{columns}[T]
  \column{0.5\textwidth}
    [Left content]
  \column{0.5\textwidth}
    [Right content]
\end{columns}

5. Content Completeness

Default: Include all content from document

• Include all main sections from source document
• Preserve all figures and tables
• Keep mathematical derivations
• Include experimental data and results

Only simplify when user explicitly requests:

• User says "简化为X页" (simplify to X pages)
• User says "只讲主要结论" (only cover main conclusions)
• User specifies specific sections to include/exclude

When content exceeds reasonable slide count:

• Ask user which sections to prioritize
• Suggest splitting into multiple presentations
• Create detailed vs. abbreviated versions

Implementation

Step-by-Step Process

1. Analyze source document structure

   • Identify main sections (##)
   • Map subsections to potential frames
   • Locate figures, tables, formulas

2. Create file structure

   • Create main slides.tex
   • Create sections/ directory
   • Copy images to images/ or reference existing location

3. Generate section files

   • Create one .tex file per main section
   • Map subsections to frames
   • Preserve original narrative

4. Compile and verify

   • Run xelatex slides.tex twice
   • Check for layout issues
   • Verify image loading
   • Ensure no content overflow

Image Path Configuration

Option 1: Copy images to slides directory

\graphicspath{{../images/}}  % Relative to sections/

Option 2: Reference existing assets

\graphicspath{{../../assets/}}  % Adjust path as needed

Common Mistakes

❌ Rewording Original Content

Mistake: Summarizing or paraphrasing instead of using original text

% ❌ BAD
QTurbo通过优化方程系统提高了编译效率

% ✅ GOOD
QTurbo通过将全局混合方程系统分解为全局线性方程系统和多个局部混合方程系统，优化了用于脉冲设计的方程系统构建。这种方法通过降低计算复杂度和提高可扩展性，显著增强了方程求解过程。

Fix: Copy content directly from source document, only adapting paragraph structure.

❌ Overusing Emphasis Words

Mistake: Excessive use of "核心"、"关键"、"重要"

Fix: Use specific, descriptive language:

• "核心思想" → "设计原理" or "基本思想"
• "关键问题" → "研究问题" or "主要挑战"
• "重要突破" → "显著进展"

❌ Image Overflow

Mistake: Images exceeding page boundaries

Symptoms: Compilation warnings, content cut off

Fix: Use keepaspectratio to maintain proportions and adjust size as needed:

% ❌ BAD: May cause overflow
\includegraphics[width=\textwidth]{figure.jpg}

% ✅ GOOD: Use keepaspectratio and reasonable sizing
\includegraphics[width=0.85\textwidth,height=0.45\textheight,keepaspectratio]{figure.jpg}

% ✅ GOOD: Simple sizing for columns
\includegraphics[width=\columnwidth,keepaspectratio]{figure.jpg}

❌ Text Overflow

Mistake: Too much content on single frame

Symptoms: Content extends beyond slide boundary

Fix: Split into multiple frames or use columns:

% ❌ BAD: One long frame with 20 bullet points
\begin{frame}
  \frametitle{技术细节}
  \begin{itemize}
    \item [20 items...]
  \end{itemize}
\end{frame}

% ✅ GOOD: Split into logical groups
\begin{frame}
  \frametitle{技术细节（一）}
  [First group of items]
\end{frame}

\begin{frame}
  \frametitle{技术细节（二）}
  [Second group of items]
\end{frame}

Real-World Impact

Using this skill produces academic presentations that:

• Accurately represent original research or documentation
• Maintain narrative flow and technical precision
• Follow academic standards for formal presentations
• Avoid layout issues that distract from content
• Preserve all important content unless explicitly simplified

Example outcomes:

• 30-40 page academic presentations from papers
• Conference presentation slides with proper structure
• Technical talks that preserve original terminology and logic
• Research group presentations maintaining complete technical accuracy
