File contents

Slide Generator: Build Step

Assemble the final PowerPoint file (.pptx) from the presentation markdown and generated images. Uses python-pptx to create a professional slide deck with the selected template.

Pre-loaded Context

Working directory: !pwd

Available presentation files: !ls -la *.md 2>/dev/null | grep -i pres || echo "No presentation files found"

Available images: !ls images/ 2>/dev/null | wc -l || echo "0"

Available templates: !sg list-templates 2>&1 || echo "Cannot list templates"

Prerequisites

Preflight: sg --version must succeed before proceeding — if sg is missing, stop and tell the user this requires the private davistroy/slide-generator engine (owner-only; see ADR-0008)
slide-generator package installed
A presentation.md file with slide content
Generated images in images/ directory (optional — builds without images if missing)

Input Validation

Required:

<presentation.md> - Path to presentation markdown file

Optional:

--template <name> - Template to use (default: generic). Use sg list-templates to see options
--style <path> - Custom style JSON file for colors, fonts, sizing
--output <path> - Output .pptx file path

Instructions

Verify input: Confirm presentation markdown and images exist
List templates (if user hasn't specified):
```
sg list-templates
```

Run build:

sg build presentation.md --template generic

Verify output: Confirm .pptx file was created
Report results: Show file path, file size, slide count

How It Works

The build step:

Parses markdown into structured slide data (titles, bullets, notes, image refs)
Classifies each slide type (title, content, two-column, image-heavy, etc.)
Applies template layout rules for each slide type
Embeds generated images at appropriate positions
Adds speaker notes, slide numbers, and footers
Uses dynamic year detection for copyright footers

Error Handling

Error	Cause	Fix
`Template not found`	Invalid template name	Run `sg list-templates`
`No slides parsed`	Malformed markdown	Check presentation.md format
`Image not found`	Missing image file	Re-run `sg generate-images` or use `--skip-images`
`python-pptx error`	Template corruption	Try a different template

Output

The build step produces:

A .pptx PowerPoint file ready for presentation
File is named based on the topic or output flag

Custom Templates

Install custom templates to ~/.slide-generator/templates/<name>/:

Must contain a .pptx template file
Optional template.py extending PresentationTemplate
Optional style.json for color/font configuration
