Summary
This wraps Vercel's Firecracker microVM service for running untrusted code in ephemeral, isolated environments. The skill covers the full pattern: spinning up a sandbox, installing dependencies (including system libs for Chromium), running commands, and tearing it down. The browser automation examples are solid and show real use cases like screenshots, accessibility snapshots, and multi-step form workflows. The snapshot feature is the performance trick here: pre-bake your dependencies into a VM image so cold starts drop to under a second instead of waiting through package installs every time. Reach for this when you need to execute user-generated code, run AI agent tools safely, or automate headless browsers without trusting the input.
