LianTai (莲台)

Cross-platform launcher: open a terminal, activate a conda / venv Python environment, optionally resume an AI agent session (opencode, codex, claude, cursor, gemini), and place the window anywhere on screen — from one command.

跨平台终端启动器：一条命令开新终端、激活 conda 或 venv 的 Python 环境、续接 AI agent 的对话 session（opencode / codex / claude / cursor / gemini），并可以把窗口放到屏幕任意位置。

Why

Tabby / Windows Terminal / iTerm2 each have their own profile system, and none of them know about conda environments or AI agent sessions. LianTai bridges that gap with a single, dependency-free Python CLI that works on Windows, macOS, and Linux.

Architectural inspiration: muxy's AIProviderRegistry / AIAgentLaunchProvider and tabby's Shell / ProfileProvider abstractions.

Install

pip install liantai
# or from source:
pip install .

Requires Python ≥ 3.9. No runtime dependencies (optional rich for prettier output).

Quick start

# List discovered Python environments
liantai envs

# List opencode sessions
liantai sessions

# List installed AI agent CLIs
liantai agents

# List sessions for any supported agent
liantai agent-sessions --agent opencode

# Open a terminal, activate conda env 'dev', do nothing else
liantai --env dev

# Open a terminal, activate 'dev', and resume an opencode session
liantai --env dev --opencode ses_0858eeaa6ffeSOGKMMSZslLEhf

# Agent-agnostic form (works for codex / claude / cursor / gemini too)
liantai --env dev --agent codex --session <session-id>

# Open Windows Terminal at (100,100) sized 1200x800
liantai --env dev --terminal wt --geometry 100,100,1200,800

# Run an arbitrary command after activation
liantai --env dev -- python -c "import sys; print(sys.executable)"

Commands

Configuration (optional)

~/.config/liantai/config.toml:

terminal = "wt"
env = "dev"
shell = "powershell"
cwd = "C:\\Users\\frede"
hold = true

[geometry]
x = 100
y = 100
width = 1400
height = 900

Supported AI agents

• opencode (sessions discovered from the SQLite DB at ~/.local/share/opencode/opencode.db)
• codex (codex --resume <id>)
• claude code (claude --resume <id>)
• cursor (cursor-agent --resume <id>)
• gemini (gemini --resume <id>)

Use liantai agents to see which are installed on PATH.

Supported terminals

• Windows: Windows Terminal (wt), Tabby, ConEmu, plain cmd.exe
• macOS: Terminal.app, iTerm2
• Linux: gnome-terminal, Konsole, Kitty, Alacritty, xterm

The first available launcher on the current OS is used unless -t is given.

Window positioning

• Windows: SetWindowPos via ctypes (no extra deps)
• macOS: AppleScript System Events
• Linux: wmctrl or xdotool (auto-detected)
