presentation-builder

Create PowerPoint presentations programmatically or via prompt guidance. Works in two modes: structure and content planning (always available) and PPTX generation (requires python3 + python-pptx).

Approach

Mode 1: Structure & Content (always available, no dependencies)

Help the user plan and write presentation content using proven frameworks.

Pyramid Principle (Minto/McKinsey)

1. Start with the answer/recommendation (BLUF -- Bottom Line Up Front)
2. Group supporting arguments (3-5 max per slide)
3. Order logically: time, structure, importance
4. Use "So what?" test for every slide

Slide Structure Templates

• Title Slide: Title + subtitle + date + presenter
• Agenda/TOC: 3-5 main sections with time allocations
• Problem Statement: Context -> Problem -> Impact -> Urgency
• Data Slide: Title as insight (not topic), chart/table, source, takeaway
• Comparison: Side-by-side, pros/cons, before/after
• Timeline/Roadmap: Phases, milestones, dependencies
• Summary/Next Steps: Key decisions, action items, owners, deadlines

Design Guidelines (Tufte-inspired)

• Data-ink ratio: maximize information, minimize decoration
• One idea per slide
• Max 6 bullet points per slide, max 6 words per bullet (6x6 rule)
• Use speaker notes for detail, not the slide
• Consistent fonts: 28-36pt titles, 18-24pt body
• High contrast colors for readability

Presentation Length Guide

• 5 min pitch: 5-7 slides
• 15 min update: 10-12 slides
• 30 min presentation: 15-20 slides
• 60 min deep dive: 25-35 slides

Mode 2: PPTX Generation (requires python3 + python-pptx)

Note: PPTX generation (Mode 2) requires python3 and python-pptx (pip3 install python-pptx). Mode 1 (markdown structure) works without any dependencies.

If python3 is available and python-pptx can be installed:

# Install python-pptx
pip3 install python-pptx

Example: Generate a PPTX with Python

from pptx import Presentation
from pptx.util import Inches, Pt
from pptx.enum.text import PP_ALIGN

prs = Presentation()

# Title slide
slide = prs.slides.add_slide(prs.slide_layouts[0])
slide.shapes.title.text = "Quarterly Business Review"
slide.placeholders[1].text = "Q1 2026 — Company Name"

# Content slide with bullets
slide = prs.slides.add_slide(prs.slide_layouts[1])
slide.shapes.title.text = "Key Highlights"
tf = slide.placeholders[1].text_frame
tf.text = "Revenue grew 15% YoY"
tf.add_paragraph().text = "Customer base expanded to 10,000+"
tf.add_paragraph().text = "Net retention rate: 125%"

# Blank slide with custom positioning
slide = prs.slides.add_slide(prs.slide_layouts[6])
txBox = slide.shapes.add_textbox(Inches(1), Inches(1), Inches(8), Inches(1))
txBox.text_frame.text = "Custom positioned text"

prs.save('presentation.pptx')
print("Created: presentation.pptx")

Slide Layouts Available (by index)

• 0: Title Slide
• 1: Title and Content
• 2: Section Header
• 3: Two Content
• 4: Comparison
• 5: Title Only
• 6: Blank
• 7: Content with Caption
• 8: Picture with Caption

Safety

• Show the outline and structure before generating a PPTX file
• Confirm the output file path before saving
• Preview slide count and content summary before final generation

Semantic Integration

• Use skill_assert with presentation:created to record each generated presentation
• Use skill_assert with presentation:structured to record when an outline is finalized
• Use skill_memory_context to recall previous presentation history
• Query presentation:context for metadata about presentations (slide counts, topics)
