Issue with current documentation:

How can I elegantly trim tool messages? I am currently facing a difficulty in building a browser use tool, but there are a large number of AIMessages and ToolMessages in the cycle. ToolMessages contain a large number of parsed web page viewport elements, which is not very user-friendly for me. There are also a large number of tokens and slow generation.

Idea or request for content:

No response

Cannot be removed directly. If the information before removal is used, React is likely to restart execution

Perhaps some sort of summarization node? See ref here: https://langchain-ai.github.io/langmem/guides/summarization/?h=summar

We're working on improving these docs on our new docs site!
