Production-Ready AI Agents: 5 Lessons from Refactoring a Monolith

Building AI agents that function effectively in real-world applications requires more than just elegant coding; it involves addressing challenges such as rate limits, scaling, and avoiding operational failures. The AI Agent Clinic was launched to tackle these challenges, with the first episode focusing on a sales research agent named "Titanium." Originally a monolithic Python script limited to hardcoded data, Titanium was restructured into a distributed framework using Google’s Agent Development Kit (ADK), enhancing reliability and scalability. The transformation included creating specialized sub-agents, implementing structured outputs with Pydantic, and replacing hardcoded information with a dynamic data intake system. Observability was improved through OpenTelemetry, and cost optimization was achieved by leveraging ADK's orchestration features. The series aims to help others diagnose and refactor problematic agents by inviting submissions for live analysis and improvement.
