PPTX Generation Skill

Purpose

Generate professional Microsoft PowerPoint presentations (.pptx) from Prometheus course data. Creates SAT-compliant training slides with speaker notes, visual hierarchy, and consistent branding.

Prerequisites

This skill works alongside:

• /sat-courseware - Provides data structure and Bloom's validation
• document-skills:pptx - Provides low-level PPTX manipulation

Slide Design Standards

Typography

Colour Palette

Visual Guidelines

1. One idea per slide - Avoid overcrowding
2. 6x6 Rule - Maximum 6 bullets, 6 words per bullet
3. Visual balance - Text on one side, visual on other
4. Consistent animation - Fade or Appear only, no distracting transitions
5. High contrast - Ensure readability from back of room

Generation Pattern

Copyfrom pptx import Presentation
from pptx.util import Inches, Pt
from pptx.enum.text import PP_ALIGN
from pptx.dml.color import RgbColor

    Generate a lesson presentation from course data.

    Args:

        template_path: Path to PPTX template
        output_path: Output file path

    """
    # Load template
    prs = Presentation(template_path)

    # Find lesson in course data

Batch Generation

Generate all lesson presentations for a course:

Copydef generate_all_presentations(course_data: dict, template_path: str, output_dir: str):
    """Generate presentations for all lessons in a course."""
    generated = []

    for clo in course_data["clos"]:
        for topic in clo["topics"]:
            for subtopic in topic["subtopics"]:
                for lesson in subtopic["lessons"]:
                    output_path = f"{output_dir}/presentation_{lesson['id']}.pptx"
                    generate_lesson_presentation(
                        course_data=course_data,
                        lesson_id=lesson["id"],
                        template_path=template_path,
                        output_path=output_path
                    )
                    generated.append(output_path)

    return generated

Validation Checklist

Before generating presentations:

• All teaching points have content
• Speaker notes are substantive (not just placeholders)
• Objectives use Bloom's-validated verbs
• Timing allocations sum to lesson duration
• Visual placeholders have alt text for accessibility
