Why

Claude Code runs in your terminal. When it spawns background work or parallel agents, you can't see what's happening. This skill creates tmux sessions that automatically open an observer window, so you can watch Claude work in real-time.

Useful for:

Running Claude agents you want to monitor
Parallel workstreams in separate panes
Long-running tasks that benefit from visibility
Debugging agent behavior

Components

**`tmux-spawn.md`** - The skill definition. Gives Claude Code the `/tmux-spawn` command.

**`lib/tmux-spawn.sh`** - A bash library with functions for session management, command sending, and Claude launching. Can be sourced independently for scripting.

Quick Start

git clone https://github.com/jimmc414/tmux-spawn-skill-for-claude-code

Or just copy the repo files anywhere locally.

In Claude Code, reference the install prompt and ask it to install:

> @install_prompt.md install this skill

Claude will read the file and ask you questions about installation scope, Python environment, and default launch flags. It may ask follow-up questions to clarify your preferences.
