Generate and maintain file indexes in markdown documents by scanning folders and updating or creating organized file listings.

• Scans target markdown files and discovers files matching specified patterns in designated folders
• Generates three table format options: simple lists with descriptions, detailed tables with type/size metadata, or categorized sections grouped by file type
• Automatically identifies existing index sections by heading patterns ("index", "files", "contents") and updates them while preserving document structure
• Extracts file metadata including name, type, description from comments or headers, size, and modification date for comprehensive indexing
• Uses relative paths for all file links and sorts results alphabetically by default
