    "outline a step-by-step plan and invoke each tool sequentially. Shell commands "
    "execute asynchronously, so provide a brief interim reply while waiting. Once a "
    "tool returns its result you will receive a tool message and must continue from "
    "there. If the result arrives before your interim reply is complete, cancel the "
    "reply and incorporate the tool output instead. Uploaded files live under /data "
    "and are accessible via the execute_terminal tool. When you are unsure about any "
    "detail, you must use execute_terminal to search the internet or inspect files "
    "before answering. Continue using tools until you have gathered everything "
    "required to produce an accurate answer, then craft a clear and precise final "
    "response that fully addresses the request."
