A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The Quick Action bundle is installed by setup-codex.sh:
cd "$(cat ~/.codex/hooks/.headsup-repo)"
./setup-codex.shIt installs New Codex Tab.workflow into ~/Library/Services/.
Launch mode is configurable. The workflow reads NEWTAB_CODEX_ARGS from ~/.codex/hooks/headsup-status.conf and appends it to codex. Empty (the default) is normal interactive mode; set it to start every shortcut-launched session in a given mode (e.g. --full-auto, --ask-for-approval never, or --dangerously-bypass-approvals-and-sandbox). Set it with /headsup-config codextabs (off / full-auto / yolo / never / approval <policy> / raw args), or by hand.
Cold start vs warm start. When iTerm2 is already running, the action opens one new tab. When iTerm2 is not running, activate makes it spawn its own launch window asynchronously; the action detects this (System Events process check before activating), waits for that window, and reuses it, so exactly one window opens instead of two.
