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 configure           # re-pick stack profile + opt-in hook packs
#   kei pick                # interactive picker → set primary → launch it
#   kei agent <name> "<task>"        # invoke agent, backend from DNA → primary
#   kei agent --on=<backend> <name> "<task>"   # override backend
#   kei run-via <backend> <name> "<task>"      # invoke agent on explicit backend
#                           # backends: claude grok agy copilot kimi codex
#                           # `kei run-via list` shows install status + agents
#   kei primary [<backend>] # get/set primary LLM provider (DNA fallback)
#   kei mcp-wire [<cli>]    # wire kei-mcp into a CLI's MCP config + hook setup
#                           # (Phase C cross-CLI policy enforcement)
#   kei mcp-wire --list     # show enforcement tier per CLI
#   kei limits              # probe each CLI's subscription quota (best-effort)
#                           # (4 of 5 CLIs have no public API — honest report)
#   kei --on=<backend>      # one-shot launch of <backend> (does not change primary)
#   kei [args...]           # splash → exec primary CLI (default: claude)
#
# 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`.

set -e

# --- subcommand dispatch (before splash) ---------------------------------
# `kei message ...`  → mailbox CLI
# `kei configure`    → hook/stack re-picker
# `kei agent ...`    → DNA-resolved agent (manifest provider → primary → claude)
# `kei run-via ...`  → explicit-backend agent invocation
# `kei primary ...`  → get/set primary LLM provider
# rest = splash + launch claude (legacy primary).
