Command Execution with ChildProcess

Overview

The ChildProcess module provides type-safe, testable process execution with automatic resource cleanup. Use this for spawning child processes, running shell commands, capturing output, and managing process lifecycles.

When to use this skill:

• Running shell commands or external programs
• Spawning child processes with controlled stdio
• Capturing command output (string, lines, stream)
• Managing long-running processes with cleanup
• Setting environment variables or working directories
• Piping commands together

Note: This skill covers the ChildProcess module for process execution, NOT effect/unstable/cli for building CLI applications.
