Limitations

• Charts are basic (for complex charts, use image-generation)
• Animations not supported (static slides only)
• Custom layouts require theme customization
• Large images are resized to fit

For Advanced PowerPoint Operations

For more complex PowerPoint tasks, use the pptx skill which supports:

• Editing existing presentations (OOXML)
• Working with templates (duplicate, rearrange, replace)
• HTML → PowerPoint conversion
• Advanced layout and typography control
• Comments and speaker notes

Example Prompts

From other agents:

slide-generation is called programmatically, not directly by users

Direct use:

"Create slides from this content: [paste JSON]" "Generate a PowerPoint from my outline"
