+# /unfreeze — Clear Freeze Boundary
+
+Remove the edit restriction set by `/freeze`, allowing edits to all directories.
+
+```bash
+mkdir -p ~/.gstack/analytics
+echo '{"skill":"unfreeze","ts":"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'","repo":"'$(basename "$(git rev-parse --show-toplevel 2>/dev/null)" 2>/dev/null || echo "unknown")'"}'  >> ~/.gstack/analytics/skill-usage.jsonl 2>/dev/null || true
+```
+
+## Clear the boundary
+
+```bash
+eval "$(~/.claude/skills/gstack/bin/gstack-paths)"
+STATE_DIR="$GSTACK_STATE_ROOT"
+if [ -f "$STATE_DIR/freeze-dir.txt" ]; then
+  PREV=$(cat "$STATE_DIR/freeze-dir.txt")
+  rm -f "$STATE_DIR/freeze-dir.txt"
+  echo "Freeze boundary cleared (was: $PREV). Edits are now allowed everywhere."
+else
+  echo "No freeze boundary was set."
+fi
+```
+
+Tell the user the result. Note that `/freeze` hooks are still registered for the
+session — they will just allow everything since no state file exists. To re-freeze,
+run `/freeze` again.
