Build, Test, Deploy, Monitor: The Agent Development Lifecycle Explained
LangChain defines a four-phase agent development lifecycle: build, test, deploy, monitor.
“What is the agent development lifecycle? So the agent development lifecycle is the process that agent engineers use to build and improve their agents.”
LangChain outlines a four-phase agent development lifecycle covering build, test, deploy, and monitor stages. The framework emphasizes real-input testing with expected outputs and production monitoring via tracing and evals. This is a useful framing for practitioners but represents standard DevOps adapted for agents rather than a novel announcement.
