Core Components

1. The Brain (Gemini Pro + ADK)

from google_adk import Agent
 
agent = Agent(
    model="gemini-2.5-pro",
    system_prompt="You are a witty personal assistant named YourGPT..."
)

2. Tools

Tool	Purpose
`web_search`	Find facts online
`code_interpreter`	Run Python for math
`memory_layer`	Remember user preferences
`calendar`	Check and create events

3. Memory (Redis-backed)

memory = Memory(backend="redis://localhost:6379")
 
agent.on_start(lambda: memory.load_user_profile())
agent.on_end(lambda: memory.save_conversation())

4. Voice (Optional)

if mode == "voice":
    agent = LiveAgent(
        model="gemini-2.0-flash-live",
        voice="nova"
    )

Implementation Steps

Initialize ADK Agent with Memory
Register Tools (Search, Code, Calendar)
Add System Prompt with personality
Connect to Streamlit/React UI
Add voice mode (optional)
Deploy to Cloud Run
Add observability (LangSmith)

Going Further

Add more tools (email, file management, browser control)
Fine-tune a personality
Add multi-user support
Implement agent skills marketplace

Congratulations!

You have gone from "What is a token?" to building a full-stack, multimodal, tool-using, remembering AI agent.

Welcome to the era of Agentic Engineering. The code you write today doesn't just execute instructions; it pursues goals.
