LangChain: Build Agents by Lifecycle
LangChain · x · 2026-07-18
LangChain argues that Agents are not regular software because they handle massive inputs and produce non-deterministic outputs. Building them using traditional software methods is prone to failure.
They propose an agent development lifecycle centered around LangSmith:
- Build: Construct the agent
- Test: Test behaviors and outcomes
- Deploy: Launch and deploy
- Monitor: Continuously monitor
The core takeaway is that agents require a dedicated engineering process, rather than the single-release mindset of traditional software.
