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

User requests (one per turn):
user: First cd within the 'ResearchDocs' directory and then locate any files titled 'report.csv'.
user: Once you locate 'report.csv' in the 'ResearchDocs' directory, delve into it to find lines that reference the 'Quarterly Financial Overview'.
user: Extract and display the last several lines from the 'report.csv' file in the 'ResearchDocs' directory, as these need to be emphasized for recent updates.
user: I need exactly 5 lines.
user: Logging in as USR001. Lastly, upon completion of our file review, kindly message my colleague, John Levy, add him as new contact, that 'Latest Quarter Performance has been well.'

Expected function call sequence:
GorillaFileSystem.mkdir
GorillaFileSystem.cd
GorillaFileSystem.find
GorillaFileSystem.grep
GorillaFileSystem.tail
MessageAPI.send_message
