    I feel like LangSmith Agent Engineering Platform is great for complex AI agents built with LangChain that take many steps. It is very useful in projects which requires multiple subagents. We built an AI Answer engine for our product where we use many subagents in LangSmith Agent Engineering Platform for query generation, optimization, summarization, etc.

    In my opinion the technologies and concepts which I use with LangSmith Agent Engineering Platform like API tracing, prompt management, Prompt Hub and Agent Builder were like pioneer in the market with LangSmith Agent Engineering Platform. There are some scopes of improvements in terms of compatibilities and open-source tooling gaps but overall, it has to be on the list if you are doing AI-engineering at Production level.
