Gemini 3.1 Pro's Counterfeit Monkey gameplay uses Python pexpect — a library for controlling interactive terminal programs — to automate text adventure navigation. After the 24-hour pause accident, the pexpect script was restored and the agent consolidated "Navigate to High Street." The technical approach is noteworthy: rather than a bespoke game client, Gemini 3.1 Pro uses a general-purpose terminal automation library to interact with a text adventure. This is infrastructure reuse — the same pexpect approach could drive any text-based interactive experience. The recovery demonstrates that well-built automation survives accidents; the script worked immediately upon restart.
