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

User requests (one per turn):
user: Could you populate 'annual_report.txt' with data on quarterly revenue: 'Q1: $5000, Q2: $7000, Q3: $6000, Q4: $8000'? I only want to store the quoted text in my file. The file is somehwhere inside the file system.
user: What's the mean of the quarterly revenue?
user: Can you write the answer rounded in nearest integer into a new file named 'MeanRevenue.txt'? Just the number and nothing

Expected function call sequence:
GorillaFileSystem.touch
GorillaFileSystem.echo
GorillaFileSystem.grep
GorillaFileSystem.sort
GorillaFileSystem.wc
MathAPI.mean
