ADK Dev Console

The Dev Console is a local app served at port 3001 (by default, but can be customized) during adk dev. It gives developers real-time visibility into their agent's behavior — conversations, execution traces, data, integrations, and configuration.

When to Use This Skill

Activate when users ask about:

• UI concepts — "What are Agent Steps?", "What does the Observe tab show?", "What is a turn?", "What is the component registry?"
• Dev Console navigation — "What tabs are available?", "Where do I find traces?", "How do I test RAG?"
• Reading execution data — "What do the steps mean?", "Why is my step red?", "What's the cost shown?"
• Component registry — "Where do I find custom components?", "How do I install a component?", "What components are available?"
• Specific pages — "How do I use the evals page?", "Where do I configure integrations?", "How do I search knowledge?"
• Comparing UI vs CLI — "Should I use the Dev Console or CLI for debugging?"
• Mentions of localhost:3001, "dev console", "Dev Console", "component registry", or specific tab names (Chat, Build, Components, Data, Test, Observe, Config)
