Create or use a shared markdown dead-drop for exchanging notes between two live Claude Code sessions running in parallel (separate terminals, same or related work). Use when the user says "/patchpad", "patchpad new/write/read", "set up a patchpad", "drop a note for the other session", or is manually copy-pasting text between two open Claude sessions and wants a lighter way to do it. Not for session handoff across time — that's session-kit's `/relay` + `/pickup`. patchpad is for two sessions open *at the same time*.
