Alley Oop keeps your development momentum going across sessions without the cost of replaying full conversation history. When you're ready to hand off, /alley distills your current session into a compact cold-start prompt — capturing just what the next session needs to orient and act immediately. Start the new session with /oop and you're back in the game. For parallel workstreams, /alleyarchive and /ooparchive let you branch, archive, and resume multiple threads independently.
