File Watching and Change Detection

Claude Code now actively monitors files you've previously read and notifies you of changes:

• Automatic change detection: Files you've read are tracked with timestamps
• Smart diff display: When a watched file changes, Claude shows only the modified portions with context
• Performance optimization: File change checks are batched and run asynchronously

Example: If you read a file and later it's modified externally, Claude will show:

File edited: /path/to/file.js
