/clearStart a fresh conversation (the old one stays resumable)
/compactSummarize a long conversation to free space
/contextSee what is filling the context window
/resumeGo back to an earlier conversation
/rewindUndo: roll code and conversation back
/autocompactSets how full the context window gets before automatic compaction, e.g.
