 `keep_alive_on_exit` can be overridden by the `KIMI_CODE_BACKGROUND_KEEP_ALIVE_ON_EXIT` environment variable, which takes higher priority than `config.toml`.
 
-In print mode (`kimi -p "<prompt>"`), Kimi Code runs a single non-interactive turn and exits as soon as the main agent finishes. If you launch background tasks (for example, concurrent subagents via `Agent(run_in_background=true)`) and need them to run to completion, set `keep_alive_on_exit = true`: the process then waits for every background task to reach a terminal state before exiting, bounded by `print_wait_ceiling_s`. Without it, the single turn ending tears background tasks down with the process.
+In print mode (`kimi -p "<prompt>"`), Kimi Code runs a single non-interactive turn. Before the turn ends, it holds the turn open to drain any still-running background subagents and bash, delivering their completions so the agent can react to the results; this drain is bounded by `print_wait_ceiling_s`. If you also need tasks to outlive the turn (for example, long-running subagents launched via `Agent(run_in_background=true)`), set `keep_alive_on_exit = true`: the process then waits for every background task to reach a terminal state before exiting, again bounded by `print_wait_ceiling_s`. Otherwise, any background task still running when the run exits is torn down with the process.
