LangChain's LangSmith Engine course frames AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → improvement as a development cycle around a recruiting agent. The curriculum moves from creating the agent and configuring Engine to proposing a fix, testing it, deploying it and monitoring production behavior. LangChain's announcement describes Engine as identifying and prioritizing issues from traces, drafting fixes and proposing evalA repeatable test for AI quality — a set of tasks plus scoring — used the way software teams use test suites, because model output is too variable to judge by eyeballing.Full definition → meant to prevent regressions.
The separation between proposing and testing a change is the useful idea: generating a possible repair is one step in deciding whether an agent has improved. The public syllabus gives learners a concrete workflow to study, with production monitoring feeding continued development.
