LangChain says context engineering is the biggest challenge for agent harnesses
LangChain · x · 2026-09-16
LangChain argues the biggest challenge for an agent harness is context engineering — what information an agent gets, and when. The longer the task, the harder it is to keep the context window from overloading.
Deep Agents ships with context management built in: filesystems, subagents, and skills, already wired up. Details are covered in the LangChain Academy course.
