# @description Server mode, one Linux user per account (S3): installed as
# /opt/agenthub/libexec/tool-run and named by CLAUDE_CODE_SHELL_PREFIX in
# every member pane (pane-launch). Claude Code runs each Bash command (and
# hook) as `tool-run '<command string>'`. The command runs at the kernel's
# highest OOM preference, so when memory runs out it is the command — a test
# run, a build — that is killed, never the Claude session above it that holds
# the conversation (pane-launch puts that one at 300). When the cgroup's OOM
# count moved while the command ran, Claude is told why it died.
