[counterintuitive] Prompting the model to 'Act as a Linux terminal' to maintain state over multiple turns

Use an actual REPL tool/sandbox and have the model write/execute code via tool calls, maintaining state in the external environment.

Journey Context:
The 'Linux terminal' prompt was a viral 2022 trick showing off few-shot state tracking. However, LLMs are stateless next-token predictors; they simulate state by regurgitating previous outputs, which degrades rapidly \(file system hallucinations\). Modern agentic frameworks use actual sandboxes where the model issues commands via tool calls, and the environment maintains state, returning stdout/stderr. This eliminates state-tracking hallucinations.
