Individual skill
stackblitz-hello-world
Build a minimal, controlled WebContainer smoke test that boots once, mounts a small project, observes process exit, and captures the preview URL. Use when proving browser/runtime compatibility before building a larger in-browser development experience. Trigger with "StackBlitz hello world", "test WebContainers", or "run Node in the browser".

# WebContainer Controlled Smoke Test
## Overview
This skill adds or plans the smallest useful WebContainer proof: one instance, one deterministic file tree, one bounded dependency install, one server process, and one preview readiness observation. It avoids presenting a tutorial snippet as a production architecture.
## Prerequisites
- A browser application already passing the StackBlitz integration preflight
- Cross-origin isolation and HTTPS behavior verified for the target environment
- A small synthetic project that contains no proprietary source or secrets
## Tool Discipline
Use `Read`, `Glob`, and `Grep` to establish the application entrypoint, package versions, and existing lifecycle ownership. Use `WebFetch` only for current official StackBlitz or WebContainers documentation. Use `Write` or `Edit` for a user-requested smoke-test implementation after inspection.
