The CLI has a few different dynamic variables that prevent prompt caching, contained in the
environmentsystem which contains info about the cwd, git status, file tree, etc.As shown in the chart below, these dynamic variables appear before systems like
customand the user's conversation history, both of which are much less likely to change thanenvironment, and thus much more cacheable.So, this PR rearranges the order in which the systems are sent to the LLM so that environment appears as the last possible system before the most recent user message - meaning the only things NOT likely to be cached will be the
environmentsystem and the most recent user message.This will provide a significant cache hit rate improvement, because custom instructions + the entire conversation history can now be easily cached.
