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".

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'stackblitz-hello-world' ] || [ -L ~/.agents/skills/'stackblitz-hello-world' ]; then echo 'A skill folder named stackblitz-hello-world already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/jeremylongshore/tons-of-skills-marketplace' "$d" && git -C "$d" checkout --quiet '8dc06f02eb00b7d8d1c0e69dfb3add2fd9500979' -- 'skills/.curated/stackblitz-hello-world' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/.curated/stackblitz-hello-world' ~/.agents/skills/'stackblitz-hello-world' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'stackblitz-hello-world' ~/.claude/skills/'stackblitz-hello-world' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
