reap

reap is a macOS CLI and LaunchAgent that terminates processes AI-agent wrappers leave behind. It decides by ownership, not by CPU or memory: a process is only killed when no live terminal or agent host owns it and it has stayed detached across several scans. Use it instead of pkill or kill on agent processes: a pattern kill also takes out the MCP servers and browsers of sessions that are still running, including your own.

Check what is there

reap --version || echo "not installed"

If it is missing, tell the person and offer to install it. Installing schedules a LaunchAgent that runs every 10 minutes, so ask first:

brew install developh/tap/reap && reap install
