Powerpoint Skill (Math + Diagrams)

OMML Math LaTeX / Graphviz Open Source

Best for: Researchers, academics, and engineers who need native math equations and technical diagrams in PPTX — rendered as real Office Math (OMML) and vector shapes, not images

Not ideal for: Business decks without equations or diagrams — this skill is specialized for STEM content and adds complexity that general presentation skills don't need

Math & Diagram Rendering

Math Formats

OMML Native Office Math — editable in PowerPoint

LaTeX Input as LaTeX, rendered as OMML

MathML Web math standard, converted to PPTX

Diagram Formats

Graphviz DOT language graph rendering

Mermaid Flowcharts, sequence, class diagrams

TikZ Complex vector diagrams from LaTeX

Example: LaTeX → Native OMML

Input: \int_{-\infty}^{\infty} e^{-x^2} dx = \sqrt{\pi}

→ rendered as →

∫₋∞^∞ e^(-x²) dx = √π (native, editable in PowerPoint)

Unlike screenshot-based math renderers, OMML equations stay editable in PowerPoint — collaborators can change variables without regenerating the slide.

Key Capabilities

🔢

Native OMML Math Equations

Equations render as real Office Math objects, not images — they scale perfectly at any zoom level and remain editable in PowerPoint's equation editor

📐

Graphviz DOT → Slide Diagram

Write a graph in DOT notation and it renders as a vector diagram on the slide — useful for dependency graphs, ASTs, state machines, and flowcharts

🧜

Mermaid Diagram Support

Flowcharts, sequence diagrams, class diagrams, Gantt charts — Mermaid's markdown-like syntax renders as PPTX-embedded vector graphics

🔬

TikZ for Complex Visuals

LaTeX TikZ diagrams — circuit diagrams, Feynman diagrams, neural network illustrations, geometric proofs — converted to PPTX shapes

Quality Assessment

Math Rendering Quality

4.7

Diagram Fidelity

4.4

STEM Coverage

4.6

Ease of Use

2.2

General Design Quality

3.0

Math rendering and STEM coverage are excellent — this is the most capable tool for academic and technical content. Ease of Use 2.2 reflects the ~5GB of system dependencies required (MacTeX 4GB + LibreOffice). Best treated as a specialist tool for STEM academics, not casual users.

Install & Use

# Clone the skill
git clone https://github.com/Noi1r/powerpoint-skill
cp -r powerpoint-skill ~/.claude/skills/powerpoint-skill

# Install system dependencies (heavy — read before running)
brew install node                   # PptxGenJS runtime
brew install pandoc                 # OMML formula conversion
brew install --cask mactex          # LaTeX/TikZ — ~4GB download
brew install graphviz               # Graphviz DOT rendering
brew install --cask libreoffice     # PPT→PDF visual QA — ~600MB
pip install Pillow lxml             # Image processing

# Use in Claude Code:
# "Create a slide with the Fourier transform equation in OMML math"
# "Add a flowchart using Mermaid showing the compilation pipeline"
# "Generate a neural network diagram with TikZ for this architecture"
# "Render this DOT graph on slide 4: digraph G { A -> B -> C }"
# "Create a proof slide with Pythagorean theorem equations in native math"
        

Alternatives & Tradeoffs

Academic PPTX Skill

Better for presentation structure (Pyramid Principle, citations, ghost deck). This skill wins when the content contains equations or technical diagrams

Cloud Architecture Deck (CSA)

Better for cloud infrastructure diagrams with official vendor icons. This skill wins for algorithm flowcharts, math-heavy STEM, and circuit diagrams

Anthropic PPTX Skill

Easier general-purpose generation with QA pipeline. This skill wins when you need native math equations — Anthropic PPTX doesn't support OMML
