 `| tee ~/phase3.log` captures the full run to disk so you have the log even if the
 scrollback is gone.
 
+### Shortcut: the `longrun` helper
+
+The ByteLyst alias set (`learning_ai_devops_tools/aliases/`) ships a `longrun` helper that
+does all of the above in one command — detached `tmux` + `caffeinate` (macOS) + a
+timestamped log:
+
+```bash
+longrun phase3 <agent-cli> <all-allowed flag> "<the overnight prompt>"
+#   -> starts a detached, kept-awake, logged session named "phase3"
+ta phase3                     # reattach     (alias for tmux attach -t)
+tail -f ~/longrun-phase3-*.log   # follow output
+tmux kill-session -t phase3   # stop it
+
+awake <cmd>                   # macOS: run any command keeping the machine awake
+```
+
+Install the aliases via `learning_ai_devops_tools/aliases/install.sh` (see that folder's
+README).
