Spawn Skills

This directory contains skills for spawning external processes in new terminal windows.

Overview

Spawn skills enable Claude Code to launch external processes:

AI coding agents (Claude, Codex, Gemini, Cursor, OpenCode, Copilot)
Generic CLI commands (ffmpeg, curl, python, npm, etc.)

Both use the fork_terminal utility to create isolated terminal sessions.

Child Skills

Skill	Description	Use Case
agent	Spawn AI coding agents	Multi-provider orchestration
terminal	Spawn generic CLI commands	Non-AI command execution

When to Use

Use spawn:agent when:

Delegating tasks to external AI providers
Need interactive CLI sessions with AI agents
Browser-based authentication is required
Real-time streaming output needed

Use spawn:terminal when:

Running non-AI CLI commands (ffmpeg, curl, etc.)
Need interactive terminal for user input
Long-running processes that shouldn't block Claude

Use orchestration:native-invoke instead when:

Automating multi-provider tasks
Need parallel execution across providers
Clean result collection is important
No interactive/TTY requirements

Core Utility

Both skills use the fork_terminal Python utility:

# Located at: ./agent/fork_terminal.py
from fork_terminal import fork_terminal

# Basic usage
result = fork_terminal("command", capture=True)

# With logging
result = fork_terminal("command", log_to_file=True, log_agent_output=True)
