Build, Test, Deploy, Monitor: The Agent Development Lifecycle Explained

This post details the four phases of the agent development lifecycle: build, test, deploy, and monitor. It highlights how frameworks like Deep Agents facilitate the 'build' phase, while tools like LangSmith are crucial for 'test' (using real inputs and expected outputs), 'deploy' (into production), and 'monitor' (with tracing and evaluations). The contribution is a structured explanation of the end-to-end process for developing and improving AI agents.
