Debugging ADK Agents

Two debugging modes: adk web (browser UI + API) and adk run (CLI).

[!NOTE] Preference: For most development and debugging tasks, adk run (CLI) is preferred as it is faster and more convenient. Within adk run, query mode is preferred over interactive mode because it requires less human intervention. However, adk web is still required for UI-specific issues, session management visualization, or debugging the API server itself.

Mode 1: adk web (Browser UI + REST API)

Best for: visual inspection, session management, multi-turn testing.
