This skill executes a Python script (`revise_ppt.py`) to interactively revise a markdown file, which serves as the source for a presentation. It reads the markdown and an optional PPTX file, uses `libreoffice` to generate PNG slide previews (or falls back to text), prompts the user for changes, updates the markdown file in place, and then calls another tool (`generate-ppt`) to create a new PPTX. It also manages a JSON state file for revision tracking and attempts to auto-install Python dependencies using `pip`.
