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

User requests (one per turn):
user: In my existing folder called 'Lectures', I'd like to set up a new file called 'Notes2023.txt'.
user: Inside 'Notes2023.txt', I shall jot down some pivotal reminders: 'Study diligently, practice programming, master algorithms.'
user: Ascertain for me how many characters of text remain in this alphabetically sorted version of 'Notes2023.txt'.

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