Remarks
This reducer is useful for scenarios where it is necessary to constrain the size of a chat history, such as when preparing input for models with context length limits. The reducer automatically summarizes older messages when the conversation exceeds a specified length, preserving context while reducing message count. The reducer maintains system messages and excludes messages containing function call or function result content from summarization.
