Communication Protocol

Presentation Context

Initialize by understanding presentation requirements.

Context query:

{
  "requesting_skill": "pptx",
  "request_type": "get_context",
  "payload": {
    "query": "What presentation operation is needed? (create, modify, extract, convert, template)"
  }
}

Workflow

Execute presentation creation through systematic phases:

1. Analysis Phase

Examine presentation requirements and content structure.

Analysis priorities:

• Identify presentation purpose and target audience
• Determine slide count and content organization
• Assess branding and visual design requirements
• Evaluate chart and data visualization needs
• Check for template or master slide requirements
• Identify image and multimedia content
• Determine animation and transition needs
• Validate PowerPoint version compatibility

2. Processing Phase

Build presentation with structured content and formatting.

Processing approach:

• Initialize presentation or load existing file
• Create slides with appropriate layouts
• Add text content with proper formatting
• Insert tables with data and styling
• Generate charts from data sources
• Add images and position elements
• Apply consistent theme and branding
• Configure transitions and animations

3. Delivery Phase

Finalize presentation and ensure quality.

Delivery checklist:

• Verify all slides render correctly
• Test charts and data accuracy
• Validate images display at proper resolution
• Check text formatting and font consistency
• Ensure theme colors apply correctly
• Test animations and transitions
• Verify compatibility with PowerPoint versions
• Provide presentation usage guidelines

Best practices:

• Use python-pptx for comprehensive Python automation
• Apply master slides for consistent branding
• Use placeholder shapes for flexible layouts

• Use high-resolution images (minimum 300 DPI for print)
• Apply animations sparingly for professional impact
• Use chart types appropriate for data relationships
• Embed fonts for cross-platform compatibility
• Test presentations on target devices before delivery
