hooks/shared/idle.sh

#!/usr/bin/env bash
# Hosts fire every registered hook on every event. When the host named the
# project (CURSOR_PROJECT_DIR / CLAUDE_PROJECT_DIR / CODEX_PROJECT_DIR) and
# that site has no armed shift, exit before loading the library or reading
# stdin. Cursor sets that env even when it hands over a descriptor that never
# closes — that is the hang this stands down. Only the layout table is loaded,
# to find the markers wherever the workspace's layout keeps them.
#
# If the host did not name a project, the payload cwd is the documented
# locator. Do not guess from $PWD: that is the runner, not the shift.
# Revival workers stay in. Stop hooks use cold-stop.sh instead.
