What problem does it solve? Textbook chapters accumulate dozens of image files, and it becomes hard to know which images are actually placed in the chapter, which are unused candidates, and which are already delivered via Cloudinary. This Skill answers those questions with a read-only audit that never edits chapter files or uploads assets. ## Core Features & Use Cases - Image Inventory: Scans a chapter's .images/ folder, cross-references each file against the chapter Markdown, and classifies every image as placed, unplaced, cloudinary, or unknown. - CSV and Table Reports: Produces a Markdown summary table and an optional CSV with filename, path, size, dimensions, format, and placement reference. - Unplaced Image Recommendations: Suggests which chapter sections unused images might fit, based on filenames and section headings, without ever auto-placing them. - HTML Gallery Generation: Builds a self-contained, filterable thumbnail gallery (gallery.html) with full-size preview on demand. - Use Case: Before finalizing BITM330 chapter 5, run an inventory to discover three unplaced screenshots, get section recommendations for each, and generate a gallery to review them visually with the editorial team. ## Quick Start Ask the assistant to generate an image inventory for chapter ch05 showing which images are placed and which are unused.
