01 / The short version
What happened
A LangChain representative argues that context engineering still faces open challenges despite industry convergence on agent architectures. The rise of proactive, always-on agents introduces difficulties in notification calibration, memory management, asynchronous task coordination, goal tracking, alignment against reward hacking, and browser-based tool use. The author notes that LangChain's LangSmith platform assists with agent debugging and deployment.
