Install

pip install tmuxx
# or, on managed systems (Debian/Ubuntu):
pipx install tmuxx
# optional Node wrapper (expects tmuxx binary in PATH):
npm install -g tmuxx

Requires Python 3.10+ and tmux. The npm package is a thin wrapper that forwards to the tmuxx binary.

Usage

# default: interactive TUI
tmuxx

# explicit TUI mode
tmuxx tui

# deterministic agent automation mode
tmuxx agent --help

# binary version
tmuxx --version

Agent Orchestration

Run parallel AI agents in isolated git worktrees, each with its own branch and tmux window. Monitor all agents with pane-level activity visibility — see which ones are running, idle, or blocked on user input.

Deterministic Workflow Commands

tmuxx agent start-task <session_name> "<prompt>" [--branch ...] [--base-branch ...] [--agent-command ...]
tmuxx agent task-report <branch>
tmuxx agent complete-task <branch> [--test-command ...] [--commit-message ...]
tmuxx agent abort-task <branch>

Recommended command flow for skills:

1. start-task creates worktree + tmux window and runs the agent command.
2. task-report provides branch status, diff, and log presence with stable fields.
3. complete-task or abort-task performs capture + cleanup in one operation.

JSON-first Mode

All tmuxx agent commands support --json for machine-safe parsing:

tmuxx agent list-worktrees --json
tmuxx agent start-task dev "fix login bug" --json
tmuxx agent task-report fix-login-bug --json
tmuxx agent complete-task fix-login-bug --test-command "pytest -q" --json

run-and-capture is scoped to the command you send (it returns command-local output, not full pane scrollback).

Legacy MCP Compatibility (Optional)
