Add other File Utilities, include - List Directory - Search for file - Move - Copy - Remove file Bundle as toolkit Add a notebook that connects to the Chat Agent, which somewhat supports multi-arg input tools Update original read/write files to return the original dir paths and better handle unsupported file paths. Add unit tests
