KeiSeiKit-1.0/bin/kei

#!/usr/bin/env bash
# kei — KeiSeiKit launcher with TUI splash, then exec claude.
#
# Distinct from `keisei` (Rust exobrain CLI: `keisei attach/mount/...`).
# `kei` is the lightweight splash + launch entry point most users want.
#
# Usage:
#   kei                     # splash → claude (interactive REPL)
#   kei --no-splash         # skip splash → exec claude
#   kei --status            # status only, don't launch claude
#   kei message ...         # inter-session mailbox (send/inbox/list) — see kei-message.sh
#   kei [args...]           # splash → claude args... (forwarded verbatim)
#
# The splash shows: substrate version, agent count, last sleep run,
# active sessions (kei-ping). Press any key to skip the dwell.
#
# Returns: same exit code as `claude`.

# --- subcommand dispatch (before splash) ---------------------------------
# `kei message ...` → the mailbox CLI; everything else falls through to launch.
