A step-by-step first run, written for someone who has never opened a sandbox. Raj provisions one from Python, executes a command inside it, installs pandas, and moves files around with the File API. Then he checks the part most getting-started guides skip: whether any of it survives. Files written in one call are still there in the next, the package still imports after a snapshot, and after a suspend and resume the same pandas 2.3.1 comes back without a rebuild. Seven short steps, no agent loop and no framework, just the sandbox lifecycle on its own.
We didn’t write this one — it’s Raj Kumar’s piece, published on Towards AI. The note above is ours; the full article is theirs.
