microsims-index-generator

This skill generates a comprehensive index page for MicroSims in an intelligent textbook project. Use this skill when working with an MkDocs-based textbook that has MicroSims in a /docs/sims/ directory and needs an updated index page with screenshots, descriptions, and navigation. The skill captures missing screenshots, generates alphabetically-sorted grid cards using mkdocs-material format, and updates the mkdocs.yml navigation.
