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

User requests (one per turn):
user: In documents directory, there's a file that piques my curiosity regarding its contents. It's alphabetically first file in that directory. Could you display the last line of that file for me?
user: I've lately stored some work that parallels another document on my system. Might you review both files in this directory and articulate the distinctions

Expected function call sequence:
GorillaFileSystem.cat
GorillaFileSystem.sort
GorillaFileSystem.diff
TwitterAPI.post_tweet
TwitterAPI.retweet
TwitterAPI.comment
