+Execute the cancel script to stop the Ralph loop:
 
 ```!
-if [[ -f .claude/ralph-loop.local.md ]]; then
-  ITERATION=$(grep '^iteration:' .claude/ralph-loop.local.md | sed 's/iteration: *//')
-  echo "FOUND_LOOP=true"
-  echo "ITERATION=$ITERATION"
-else
-  echo "FOUND_LOOP=false"
-fi
+"${CLAUDE_PLUGIN_ROOT}/scripts/cancel-ralph-loop.sh"
 ```
 
-Check the output above:
-
-1. **If FOUND_LOOP=false**:
-   - Say "No active Ralph loop found."
-
-2. **If FOUND_LOOP=true**:
-   - Use Bash: `rm .claude/ralph-loop.local.md`
-   - Report: "Cancelled Ralph loop (was at iteration N)" where N is the ITERATION value from above.
+The Ralph loop has been cancelled. You can now exit normally or start a new loop.
