The **abigail‑plugin‑exit** package is a built‑in plugin for the Abigail v1 task runner. It makes Abigail automatically terminate with exit code 1 when no task is specified or when any of the executed tasks return a non‑zero status (unless overridden by the watch plugin). It’s intended for developers using Abigail who want a simple way to enforce failure detection in their command‑line workflows.
