RU: Stop
EXECUTE IMMEDIATELY: Use the Bash tool to run the following script.
/usr/bin/env bash << 'RALPH_UNIVERSAL_STOP'
PROJECT_DIR="${CLAUDE_PROJECT_DIR:-$(pwd)}"
echo "Stopping RU loop..."
# Set state to stopped
STATE_FILE="$PROJECT_DIR/.claude/ru-state.json"
if [[ -d "$PROJECT_DIR/.claude" ]]; then
echo '{"state": "stopped"}' > "$STATE_FILE"
fi
# Create kill switch for redundancy
touch "$PROJECT_DIR/.claude/STOP_LOOP"
# Update config if exists
CONFIG_FILE="$PROJECT_DIR/.claude/ru-config.json"
if [[ -f "$CONFIG_FILE" ]]; then
jq '.state = "stopped"' "$CONFIG_FILE" > "$CONFIG_FILE.tmp" && mv "$CONFIG_FILE.tmp" "$CONFIG_FILE"
fi
# Clean up markers
rm -f "$PROJECT_DIR/.claude/ru-start-timestamp"
# Create global stop signal
echo '{"state": "stopped", "timestamp": "'$(date -u +%Y-%m-%dT%H:%M:%SZ)'"}' > "$HOME/.claude/ru-global-stop.json"
echo ""
echo "RU: STOPPED"
echo "Project: $PROJECT_DIR"
RALPH_UNIVERSAL_STOP
After execution, confirm the loop has been stopped.
Troubleshooting
| Issue | Cause | Solution |
| ----------------------- | --------------------- | ------------------------------------ |
| Loop continues running | Hook still active | Wait for current iteration to finish |
| State file not created | .claude dir missing | Create with mkdir -p .claude |
| jq error | Config file malformed | Delete and recreate config file |
| Permission denied | File not writable | Check directory permissions |
| Global stop not working | Different project dir | Ensure CLAUDE_PROJECT_DIR is correct |
