# Integration test: gr spawn down sends /exit before killing tmux windows.
#
# NOTE: This is a LOCAL-ONLY integration test. It requires tmux, which is
# not available on GitHub Actions runners. Run manually before merging
# spawn-related changes:
#
#   cd gitgrip && GR=./target/debug/gr ./tests/spawn_graceful_shutdown.sh
#
# Requires: tmux, gr (built), .gitgrip/agents.toml with at least one agent.
