I disagree with this method and would discourage others from using it too, especially if accuracy, faster responses, and saving money are your priorities.

This only makes sense if you assume that you are the consumer of the response. When compacting, harnesses typically save a copy of the text exchange but strip out the tool calls in between. Because the agent relies on this text history to understand its own past actions, a log full of caveman-style responses leaves it with zero context about the changes it made, and the decisions behind them.

To recover that lost context, the agent will have to execute unnecessary research loops just to resume its task.

me disagree

only you auto-compact. auto-compact bad
