Thin skill over the kei-message jsonl mailbox: /msg reads inbox, /msg @name text sends (identity = cwd basename), /msg all broadcasts, /msg list|who. send now accepts leading @name. Mirror of keigit 7b453aac.
Mirror of keigit 3aff0029. lib-hooks.sh apostrophe-in-jq closed the bash single-quote and broke every install (fixed). cortex-ui removed from profiles+menu; forgejo/zoekt source lib-launchd; portable kei-message id (BSD date fallback); non-TTY default minimal; install stamps .kei-profile; README hook count 54; web-install warns before discarding local edits in the managed clone.
Any Claude Code session can message any other (not just Agent-Teams teammates),
no tmux. Append-only jsonl bus + UserPromptSubmit hook pulling unread per turn.
kei-message.sh (send/inbox/list, address by cwd-basename or "all"),
mailbox-inject.sh (cursor dedup, first-turn baseline, no self-echo), bin/kei
`message` dispatch, lib-scaffold copies all scripts/*.sh, snippet wires the hook.
Bypass KEI_MAILBOX_BYPASS=1. Verified by 2-session simulation.
