Lessons from the Google Cloud AI Agent Bake-Off distilled into 5 architectural patterns for building production-grade AI agents. Key takeaways include decomposing complex tasks into specialized sub-agents (microservices-style), architecting for model impermanence, treating multimodality as a native feature rather than an afterthought, adopting open protocols like MCP and ADK instead of custom glue code, and using deterministic code (Pydantic validation + Python/SQL) for critical operations like financial calculations rather than relying on LLM probabilistic output.

Build Better AI Agents: 5 Developer Tips from the Agent Bake-Off

1. Break the Monolith: Architect for Multi-Agent Workflows

2. Your Agent Harness may need to be replaced tomorrow

3. Multimodality is a Core Requirement, Not an Add-On

4. Know when to use the right open source protocols: MCP, A2A, UCP, AP2, A2UI, and AG-UI

5. LLMs Reason, Deterministic Code Executes (Use Strict Schemas)
