When to Use

• User asks to "highlight" text → highlight.js
• User asks to "underline" text → underline.js
• User asks to "strikeout", "strikethrough", or "cross out" → strikeout.js
• User asks to "add note", "add comment", or "annotate" → add-note.js
• User asks to "list annotations" or "what annotations" → list-annotations.js
• User asks to "flatten" or "make annotations permanent" → flatten.js

Notes

• Search is case-sensitive and matches whole words by default
• Annotations are added to a copy; original file is unchanged
• Use list-annotations.js to see existing annotations before modifying
