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. Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

# kei-message — minimal persistent mailbox so ANY Claude Code session can message
|
|
# ANY other (not just Agent-Teams teammates). Append-only jsonl bus; the
|
|
# mailbox-inject.sh UserPromptSubmit hook pulls unread into each session's
|
|
# context per turn. Identity = basename of the session's cwd (or --from/--to a
|
|
# name), plus the broadcast channel "all".
|
|
#
|
|
# kei message send [--to <name|all>] [--from <name>] <text...>
|
|
# kei message inbox # messages addressed to me (cwd) or all
|
|
# kei message list # whole bus (recent)
|
|
# kei message channels # known recipient names
|
|
#
|
|
# Store: ~/.claude/mailbox/messages.jsonl (one JSON object per line)
