The article argues that the basic LLM-agent pattern (a model in a loop with tools and a sandbox) has become standard, and that the open problems are shifting to proactive, always-on agents. Those include deciding when an agent should notify users without overwhelming them, and handling memory over long horizons. The author concedes that LangChain and the industry lack general solutions for these yet, so readers should treat the piece as a map of unresolved design questions rather than a set of established practices.
New context engineering challenges in late 2026
LangChain CEO Harrison Chase shares insights into the biggest harness engineering challenges with the emergence of proactive agents.
It feels like everyone is converging on the same agent architecture: an LLM, running in a loop, calling tools, running in a sandbox. Claude Code - perhaps the first high profile manifestation of this - came out over a year and a half ago. Deep Agents, our agent harness, launched over a year ago. This pattern has been building for a while. There’s nothing bad with that convergence per se, but it has led to a sentiment among some AI engineers that I’ve talked to…
