+
+If you are editing Sketch from within Sketch, you can use the following to give
+Sketch a place to store its skaband client key across sessions, allowing the
+agent to iterate on itself.
+
+```
+# Outside
+mkdir -p ~/.inside-cache/webui
+go run ./cmd/sketch -docker-args "-v $HOME/.inside-cache:/root/.cache/sketch"
+# Inside
+go run ./cmd/sketch -unsafe
+```
