Cancel Ralph

First, list all active Ralph loops:

LOOPS_DIR="$HOME/.claude/ralph-wiggum-pro/loops"
found=0
# Use find to avoid shell glob expansion errors in zsh
while IFS= read -r f; do
  [[ -z "$f" ]] && continue
  if [[ -f "$f" ]]; then
    found=1
    SESSION=$(basename "$f" | sed 's/ralph-loop\.\(.*\)\.local\.md/\1/')
    DESC=$(grep '^description:' "$f" 2>/dev/null | sed 's/description: *//' | sed 's/^"\(.*\)"$/\1/' || echo "No description")
    ITER=$(grep '^iteration:' "$f" 2>/dev/null | sed 's/iteration: *//' || echo "?")
    MAX=$(grep '^max_iterations:' "$f" 2>/dev/null | sed 's/max_iterations: *//' || echo "0")
    STARTED=$(grep '^started_at:' "$f" 2>/dev/null | sed 's/started_at: *//' | sed 's/^"\(.*\)"$/\1/' || echo "unknown")
    PROJECT=$(grep '^project:' "$f" 2>/dev/null | sed 's/project: *//' | sed 's/^"\(.*\)"$/\1/' || echo "unknown")
    echo "LOOP_FOUND"
    echo "SESSION=$SESSION"
    echo "DESC=$DESC"
    echo "ITER=$ITER"
    echo "MAX=$MAX"
    echo "STARTED=$STARTED"
    echo "PROJECT=$PROJECT"
    echo "FILE=$f"
    echo "---"
  fi
done < <(find "$LOOPS_DIR" -maxdepth 1 -name 'ralph-loop.*.local.md' 2>/dev/null)
if [[ $found -eq 0 ]]; then
  echo "NO_LOOPS_FOUND"
fi

Based on the output above:

If NO_LOOPS_FOUND

Say: "No active Ralph loops found."

If exactly ONE loop found

1. Show the loop details (session ID truncated to 8 chars, description, iteration count, project)
2. Use AskUserQuestion to confirm cancellation:

   {
     "question": "Cancel this Ralph loop?",
     "header": "Confirm",
     "options": [
       {"label": "Yes, cancel it", "description": "Stop the loop and delete its state file"},
       {"label": "No, keep it running", "description": "Leave the loop active"}
     ],
     "multiSelect": false
   }
   

3. If confirmed:
   • Log and delete atomically: ${CLAUDE_PLUGIN_ROOT}/scripts/log-session.sh "<FILE>" "cancelled" "" --delete
4. Report: "Cancelled Ralph loop: <description> (was at iteration <ITER>)"
5. If not confirmed, say: "Loop not cancelled."

If MULTIPLE loops found

1. Show a summary of all loops with their session IDs (truncated), descriptions, and projects
2. Use AskUserQuestion to ask which loop(s) to cancel:
   • Create options based on the loops found, using format: "Session <id>: <description>"
   • Include an "All loops" option as first choice
   • Include a "None - keep all running" option as last choice
   • Use multiSelect: true to allow canceling multiple loops
3. If user selects "None", say: "No loops cancelled."
4. Otherwise, for each selected loop:
   • Log and delete atomically: ${CLAUDE_PLUGIN_ROOT}/scripts/log-session.sh "<FILE>" "cancelled" "" --delete
5. Report which loops were cancelled

Example AskUserQuestion format for multiple loops:

{
  "question": "Which Ralph loop(s) do you want to cancel?",
  "header": "Cancel loops",
  "options": [
    {"label": "All loops", "description": "Cancel all active Ralph loops"},
    {"label": "abc12345: Build REST API...", "description": "Iteration 5 in /Users/dev/my-project"},
    {"label": "xyz78901: Fix auth bug...", "description": "Iteration 12 in /Users/dev/other-project"},
    {"label": "None - keep all running", "description": "Don't cancel any loops"}
  ],
  "multiSelect": true
}
