+# Dev TODOs
+
+This file contains TODOs for the dev ADK module based on
+[Recommendations for making ADK Java more idiomatic](http://go/idiomatic-adk-java).
+
+## Dev UI
+
+-   [ ] **Conditional UI**: Add a configuration property (e.g.,
+    `adk.web.ui.enabled`) to conditionally enable/disable serving Dev UI static
+    assets (in `AdkWebServer`).
+-   [ ] **Integration Tests**: Add E2E tests (Selenium/Playwright/HtmlUnit) for
+    Dev UI to verify interaction between frontend assets and Spring Boot
+    backend.
+-   [ ] **Integration Tests**: Test critical paths like loading UI, WebSocket
+    connection, sending/receiving messages, and rich content handling (images).
+
+## Production Readiness
+
+-   [ ] **Actuators**: Enable and configure Spring Boot Actuator endpoints for
+    monitoring and management.
+-   [ ] **Actuators**: Configure startup and readiness probes for production
+    environments.
