This workshop was presented at the AI Coding Summit.

Repository: code-along demo repository choose "Use as template"

Learning Objectives

• Explain what a sandbox is and why it exists as a compute primitive
• Identify common problems that sandboxes are well suited to solve
• Safely execute untrusted or dynamic code
• Use sandboxes for development, testing, and automation workflows

"Helpful" Sayings

When to Use a Sandbox

• "If you might break something, sandbox first!"
• "When it’s short-lived and wild, sandbox that child!"
