What
The system prompt is the set of instructions Claude Code gives the model before your messages. Its memory section is now built asynchronously and passed through a new step. In this build that step returns the text unchanged, so the prompt the model sees is the same.
Why
Nothing changes for you in this build. This only adds a place where the memory section could be adjusted later.
