Summary
A July 2025 LangChain blog post, credited to the LangChain Team, that defines context engineering as filling an agent’s context window with just the right information at each step and groups common strategies into four buckets: write (scratchpads and memories), select (memories, tools and knowledge), compress (summarization and trimming) and isolate (multi-agent, sandboxed environments and state). It then describes how LangGraph and LangSmith support each strategy.
