Earlier this year, we introduced Gemini Enterprise Agent Platform, where you can build, scale, govern, and optimize agents. Today, we’re sharing 13 demos that walk you through what Agent Platform can do. Each one teaches a concept, a pattern, or an architecture you can put to work immediately.
The best part? You don’t have to follow them step-by-step. Install Agents CLI into your favorite coding agent (Antigravity, Claude Code, Codex, whatever you use) and it instantly gets seven skills that make it an expert in ADK and Agent Platform. Describe what you want to build in plain English, and your coding agent scaffolds, evaluates, deploys, and monitors the agent for you. You’ll never have to leave your editor.
Let’s dive in!
Build AI agents
These demos are all built on the code-first ADK. They start at the foundation and work up.
1. Start here: build your first agent with ADK. The ADK Foundation codelab is your perfect on-ramp. You set up your environment, define a basic conversational agent powered by Gemini, configure its settings, and test it through both a command-line interface and a web UI. If you’ve never touched ADK before, do this one first.
2. Build an event-driven approval agent with human-in-the-loop. The ambient expense agent codelab is the most complete “Agent Platform in action” demo in the set. You build a corporate expense agent using ADK 2.0’s graph-based workflow API. Expenses under a threshold get auto-approved in plain Python. Anything above goes through a pre-LLM security screen (PII redaction, prompt-injection defense), passes a Gemini compliance analysis, and pauses for a human-in-the-loop review before anything is finalized. You mount it behind FastAPI, trigger it from Pub/Sub events, and grade it with an LLM-as-judge eval. Keep this agent in mind – it comes back in the Scale and Govern sections.
3. Connect agents to your data with the Model Context Protocol. The MCP codelab shows you how to build reusable MCP tools that let Gemini query BigQuery, search files, and call APIs. MCP is an open protocol, so the tools you build work across different vendors and frameworks.
4. Build a dynamic frontend with Agent-to-UI (A2UI). The best user experiences are highly visual. The A2UI codelab shows you how to build an agent that renders real interface components (layouts, charts, interactive menus) that update dynamically in real time as the conversation flows. The agent literally assembles the UI the user needs, on the fly.
Scale AI agents
A prototype on your laptop is one thing. Handling production traffic, memory, and orchestration is what comes next.
5. Deploy a stateful data science agent to Agent Runtime (formerly known as Agent Engine). The Stateful Data Science Agent codelab walks you through building a BigQuery agent that remembers user preferences across sessions via Memory Bank, then deploying it directly to Agent Runtime. All of the underlying infrastructure, scaling, and session management are handled for you automatically.
6. Build long-running agents that pause, resume, and never lose context. Building an agent that responds to a single prompt is easy, but real enterprise workflows often take days or weeks to complete. This tutorial walks through building agents that run reliably for weeks. You’ll learn three architectural patterns: durable state machines, event-driven idle time handling, and checkpoint-and-resume with persistent sessions. The example is an onboarding coordinator agent that survives container restarts and picks up exactly where it left off.
7. Deploy an ambient expense agent to Agent Runtime with the Agents CLI. Remember the expense agent from the Build section? The Deploy to Agent Runtime codelab picks up that agent and takes it to production. You scaffold your deployment config with the Agents CLI, preview it with a dry run, then deploy it live. Cloud Trace, Cloud Logging, and BigQuery Agent Analytics wire in automatically, and the agent auto-registers in Agent Registry, so it’s discoverable across your org the moment it goes live.
8. Give your production agent a real front end. The frontend codelab is where everything comes together. You build a manager dashboard on Cloud Run, connect it to Agent Runtime through an OIDC-authenticated Pub/Sub pipeline, and give managers the ability to resume paused human-in-the-loop sessions from the browser. It ties the expense agent and the deployment together into a complete end-to-end enterprise architecture.
Govern AI agents
Scaling agents across an organization requires a system of built-in guardrails to manage access, track endpoints, and filter traffic.
9. Secure your agent’s lifecycle from the first commit. The Secure Agentic Coding codelab shows you how to build a shopping assistant test-first with test-driven development (TDD), wire in a custom STRIDE threat model, set up a Semgrep pre-commit hook, and configure a PreToolUse gate that blocks risky actions before execution. You deliberately plant a hardcoded API key, and the agent catches and fixes it the moment the hook fires.
10. Control agent access with Agent Gateway. The Agent Gateway codelab covers runtime governance. You deploy a multi-tool ADK agent on Agent Runtime that calls MCP servers on Cloud Run through Agent Gateway. Each agent gets a unique identity with end-to-end mTLS. Every outbound call goes through IAP authentication and IAM authorization. On top of that, Model Armor inspects all content for prompt injection and data leakage. It’s a complete, production-grade governance stack in one demo.
Optimize AI agents
Shipping an agent is the start. The hard part is knowing whether your next prompt tweak actually makes it better or quietly breaks ten other things. Agent Platform gives you the tools to close that loop.
11. Drive the agent quality flywheel from your coding agent. You tweaked a prompt. It looks better on three examples, but did you just break ten others? This tutorial introduces a five-stage evaluation flywheel you run directly from your coding agent: prepare data (from OTel traces, hand-crafted cases, or synthesized scenarios), run inference, grade with Google’s adaptive AutoRaters, analyze failure clusters, and execute targeted optimizations. The AutoRaters are built on the same principles Google uses to evaluate its own models and first-party agents, developed in partnership with DeepMind. Describe what you want measured in plain language. Your coding agent picks up the rest.
12. Build a cross-language multi-agent pipeline with A2A. In a large enterprise, different teams will inevitably build agents in different languages. This tutorial walks through a contract compliance pipeline where a Python-based agent extracts terms using Gemini and a Go-based agent validates them against corporate policy. The two services connect via the Agent-to-Agent (A2A) protocol and are orchestrated by ADK. You’ll learn how RemoteA2aAgent turns any A2A-compliant service into a local sub-agent with a few lines of code.
13. Scale agents across frameworks with CrewAI, LangGraph, A2A, and ADK. Most production teams don’t standardize on one agent framework. The codelab shows you how to orchestrate across all of them: an ADK control room delegates planning to a LangGraph state machine, which dispatches tasks to a CrewAI execution crew, all connected via the A2A protocol. If one step fails, the control room re-plans automatically.
