PPT Generation

Overview

Generate professional PowerPoint presentations. Plan the structure with a consistent visual style, generate slide content, and compose into a PPTX file.

Poirot note: The original deer-flow skill uses AI image-generation per

slide. Poirot may not have image-generation available. This version generates text-based slides with python-pptx. Install: pip install python-pptx.

When to Use

User requests to generate, create, or make presentations (PPT/PPTX)
User wants slides for a topic with structured content
User needs a visual presentation from research findings

Presentation Styles

Style	Description	Best For
dark-premium	Black bg, luminous accents, luxury aesthetic	Executive presentations
gradient-modern	Bold mesh gradients, contemporary typography	Startups, brand launches
minimal-swiss	Grid-based, bold negative space, timeless	Consulting, architecture
keynote	Apple-inspired, bold typography, dramatic imagery	Keynotes, product reveals
editorial	Magazine-quality layouts, sophisticated typography	Annual reports, thought leadership

Workflow

Step 1: Understand Requirements

Topic/subject
Number of slides (default: 5-10)
Style: dark-premium / gradient-modern / minimal-swiss / keynote / editorial
Aspect ratio: 16:9 (standard) or 4:3
Content outline: key points per slide

Step 2: Research (if needed)

Use deep-research skill to gather content for the presentation.

Step 3: Create Presentation Plan

json

{
  "title": "Presentation Title",
  "style": "dark-premium",
  "slides": [
    {"number": 1, "type": "title", "title": "...", "subtitle": "..."},
    {"number": 2, "type": "content", "title": "...", "bullets": ["...", "..."]},
    {"number": 3, "type": "chart", "title": "...", "data": {...}},
    {"number": 4, "type": "section", "title": "..."},
    {"number": 5, "type": "content", "title": "...", "bullets": ["...", "..."]},
    {"number": 6, "type": "closing", "title": "Thank You", "subtitle": "..."}
  ]
}

Step 4: Generate PPTX

bash

python3 -c "
from pptx import Presentation
from pptx.util import Inches, Pt, Emu
from pptx.dml.color import RGBColor
from pptx.enum.text import PP_ALIGN
 
prs = Presentation()
prs.slide_width = Inches(13.333)  # 16:9
prs.slide_height = Inches(7.5)
 
# Style: dark-premium
BG_COLOR = RGBColor(0x0A, 0x0A, 0x0A)
TEXT_COLOR = RGBColor(0xFF, 0xFF, 0xFF)
ACCENT_COLOR = RGBColor(0x00, 0xD9, 0xFF)
 
def add_slide(prs, layout_idx=6):  # 6 = blank
    slide = prs.slides.add_slide(prs.slide_layouts[layout_idx])
    bg = slide.background
    fill = bg.fill
    fill.solid()
    fill.fore_color.rgb = BG_COLOR
    return slide
 
def add_text(slide, text, left, top, width, height, size=24, color=TEXT_COLOR, bold=False):
    txBox = slide.shapes.add_textbox(Inches(left), Inches(top), Inches(width), Inches(height))
    tf = txBox.text_frame
    p = tf.paragraphs[0]
    p.text = text
    p.font.size = Pt(size)
    p.font.color.rgb = color
    p.font.bold = bold
    return txBox
 
# Slide 1: Title
slide = add_slide(prs)
add_text(slide, 'Presentation Title', 1, 2, 11, 2, size=44, bold=True)
add_text(slide, 'Subtitle', 1, 4, 11, 1, size=24, color=ACCENT_COLOR)
 
# Slide 2: Content with bullets
slide = add_slide(prs)
add_text(slide, 'Key Points', 1, 0.5, 11, 1, size=36, bold=True)
for i, bullet in enumerate(['Point one', 'Point two', 'Point three']):
    add_text(slide, f'• {bullet}', 1, 2 + i*0.8, 11, 0.7, size=24)
 
# Slide 3: Section divider
slide = add_slide(prs)
add_text(slide, 'Section Title', 1, 3, 11, 1.5, size=40, bold=True, color=ACCENT_COLOR)
 
# Save
prs.save('.poirot/outputs/presentation.pptx')
print('Saved to .poirot/outputs/presentation.pptx')
"

Step 5: Present

present_files([".poirot/outputs/presentation.pptx"])

Slide Types

Type	Content	Layout
title	Title + subtitle	Centered, large font
content	Title + bullets	Left-aligned, 3-5 bullets
section	Section title only	Centered, accent color
chart	Title + chart image	Chart from `chart-visualization` skill
quote	Large quote + attribution	Centered, italic
closing	Thank you + contact	Centered

Pitfalls

Too much text per slide: max 5-6 bullets, max 2 lines each. Slides are

visual aids, not documents.

Font sizes too small: title ≥36pt, body ≥24pt. If text doesn't fit,

split into more slides.

Inconsistent style: all slides must use the same color palette, font

sizes, and layout patterns.

No visual hierarchy: title > section headers > bullets > footnotes.

Use size + weight + color to establish hierarchy.

python-pptx not installed: pip install python-pptx first.
Image slides: if you need chart images, generate them first with the

chart-visualization skill, then embed as slide.shapes.add_picture().
