This wraps Vercel's Firecracker microVM infrastructure for running untrusted code in ephemeral, isolated environments. The skill focuses heavily on browser automation with agent-browser inside sandboxes, showing you how to take screenshots, grab accessibility snapshots, and run multi-step workflows like form fills. The snapshot feature is clutch: pre-bake a VM image with Chromium and dependencies so your sandbox starts in under a second instead of waiting for dnf installs every time. Use it when you need to execute AI-generated code, process user submissions, or automate headless Chrome tasks without risking your main environment. It chains from vm2 patterns with a security warning and links to AI SDK for tool-calling patterns.
