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.

Instructions: 159Files: 4Format: markdown

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)


Scope & Permissions

What this capability can and cannot access — derived from pipeline analysis

creates files

yes

deletes files

no

modifies files

yes

accesses env variables

no

invokes external tools

yes

makes network requests

no


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
