Google Cloud NEXT '26 Challenge Submission

Introduction:
At Google Cloud NEXT 26, one of the most interesting shifts wasn’t just about faster models or better APIs — it was about how developers are starting to build agents instead of traditional applications.
Instead of writing step-by-step logic, we’re now defining behavior, constraints, and goals.
I decided to explore this idea by trying to build a simple AI agent using Google Cloud tools. What I found was both exciting and slightly chaotic.
What I Tried
I attempted to create a basic AI agent that could:
1.Take a user query
2.Process it using an AI model
3.Return a structured response
The idea sounded simple. In reality, the challenge wasn’t building the agent it was controlling it
What Worked Well:
Google Cloud’s ecosystem makes it relatively easy to get started:
Integration with AI models is fast
APIs are well-documented
Deployment options like serverless reduce setup overhead
Within a short time, I had a working prototype that could respond intelligently to inputs.
The Real Problem: Lack of Guardrails
Here’s where things got interesting.
The agent didn’t always behave predictably.
Sometimes it:
Ignored instructions
Drifted away from the intended task
Produced inconsistent outputs
This made one thing very clear:
The hardest part of building AI agents is not intelligence — it’s control.
Key Insight: Context > Code
One major takeaway is that traditional coding skills are no longer enough.
To build reliable agents, you need:
Clear scope definitions
Strong prompt design
Constraints that guide behavior
Without these, the agent becomes unpredictable over time.
This aligns with a broader idea emerging from Cloud NEXT ’26:
Developers are shifting from writing logic to designing behavior.
What Could Be Improved
While the tools are powerful, there are still gaps:
No built-in “safety boundaries” for agents
Limited guidance on structuring long-running behavior
Debugging agent decisions is still difficult
These are critical areas that need improvement for real-world applications.
Conclusion
Google Cloud’s direction toward AI-driven development is clear, and it’s genuinely exciting.
However, building with AI agents requires a different mindset:
Less focus on code
More focus on control, context, and constraints
We’re not just building applications anymore — we’re designing systems that think.
And honestly, we’re still figuring out how to do that properly.
