## Summary

Philipp Schmid describes Code Mode, where an agent harness exposes a single exec(code) tool and the model writes a script that chains actions in a sandbox. Only the final text summary returns to the model's context, instead of the raw output of each call. He includes a runnable Gemini example and notes that many existing tools built for bash may not integrate cleanly.
