Batch Close All Complete Increments

Closes all active increments that have reached 100% task completion by delegating each one to sw:done. This skill is a thin batch-discovery loop; all actual closure logic (gates, reports, sync) lives in sw:done.

Step 1: Discover Closeable Increments

for meta in $(find .specweave/increments -maxdepth 2 -name "metadata.json" | sort); do
  st=$(jq -r '.status' "$meta" 2>/dev/null)
  [ "$st" != "active" ] && [ "$st" != "in-progress" ] && [ "$st" != "ready_for_review" ] && continue
  d=$(dirname "$meta"); id=$(basename "$d"); tasks="$d/tasks.md"
  [ ! -f "$tasks" ] && continue
  pending=$(grep -c '\[ \]' "$tasks" 2>/dev/null || echo 0)
  done_count=$(grep -c '\[x\]' "$tasks" 2>/dev/null || echo 0)
  if [ "$pending" -eq 0 ] && [ "$done_count" -gt 0 ]; then
    echo "CLOSEABLE: $id"
  fi
done
