Multi-turn tool-use scenario.
Tools involved: GorillaFileSystem

User requests (one per turn):
user: Pop on over to the 'Documents' directory and craft a new file dubbed 'summary.txt', would you? If it already exists, return an error
user: In 'Documents', let's capture some profound topic 'quantum computing' and jot them down in the 'summary.txt'. The file should only contain 'quantum computing' in its contents.
user: Mind tallying up the words in a file for me?
user: The file name is summary.txt

Expected function call sequence:
GorillaFileSystem.ls
GorillaFileSystem.cd
GorillaFileSystem.touch
GorillaFileSystem.echo
GorillaFileSystem.grep
GorillaFileSystem.sort
GorillaFileSystem.wc
