Interface
Skill triggers and instruction summary
Activation
Activates whenever a .pptx file is involved as input, output, or both, including creating, reading, editing, or working with presentations.
Handles all PowerPoint presentation tasks including creation, analysis, editing, template work, and content extraction from .pptx files.
Does
Extract text content from .pptx files using markitdown
Create presentations from scratch using pptxgenjs
Edit existing presentations by unpacking, modifying, and repacking
Generate visual thumbnails for presentation analysis
Apply design principles with bold color palettes and visual elements
Perform mandatory QA including content verification and visual inspection using subagents
Convert presentations to images for visual quality control
Check for placeholder text and formatting issues
Does not
Create boring plain slides with just bullets on white backgrounds
Use generic blue color schemes without topic-specific consideration
Skip the required QA verification process
Declare success without completing at least one fix-and-verify cycle
Use accent lines under titles (explicitly prohibited as AI-generated hallmark)

Known Failure Modes
Documented edge cases and recovery behaviors
when when visual QA is skipped
then the agent must use subagents for visual inspection even on small presentations
when when placeholder text remains
then the agent must grep for common placeholder patterns and fix them
when when first render has no issues found
then the agent must look more critically as problems are assumed to exist
