Vibe Check: Planning a Sailing Trip with AI Agents — ADK Go in Action

Watch the video version for the demos and screen shares: https://youtu.be/rAY1ERVJLY4Terry Ryan from Google walks us through Naval Plan, a real app he built (and actually uses) to plan sailing trips using ADK Go. The app combines agentic research — pulling from old sailing forums and local knowledge — with deterministic API calls for tides, weather, and sunrise/sunset data. We dig into how the agents are architected, the quirks of working with Google Search as a tool in ADK, and Terry's dev workflow using Gemini CLI.Topics covered:Building Naval Plan: an agentic sailing trip planner with ADK GoMixing agentic research with deterministic API tools (tides, weather, sunrise/sunset)ADK agent architecture: subagents, tool composition, and the Google Search tool workaroundStructured JSON output from agents and how to make it reliableDev workflow: Gemini CLI in YOLO mode, git-based rollback, and prompt managementUsing LiteLLM for multi-model support in ADKTool count limits and context window considerationsUpcoming Temporal + ADK integrationLinks mentioned:ADK: https://adk.devNaval Plan walkthrough video: https://www.youtube.com/watch?v=kwSVtQ7dziUCharm (Go terminal UI libraries): https://charm.shGoogle Cloud Next (Las Vegas): https://www.googlecloudevents.com/next-vegasOriginally published April 6, 2026 on Vibe Check Temporal YouTube channel and you can watch the full episode at: https://youtu.be/rAY1ERVJLY4
