Individual skill
stackblitz-local-dev-loop
Establish a reproducible local development and browser-test loop for a WebContainer host, including isolation-header assertions, single-boot behavior under HMR, and cleanup checks. Use when a StackBlitz integration works manually but lacks dependable regression coverage. Trigger with "test WebContainers locally", "StackBlitz dev loop", or "WebContainer Playwright test".

# WebContainer Local Development Loop
## Overview
This skill turns a manually tested WebContainer host into a repeatable local loop. It separates pure file-tree and state-machine tests from browser integration tests that require SharedArrayBuffer, Service Workers, WebAssembly, and real response headers.
## Prerequisites
- A named host application with an existing test framework or permission to add focused coverage
- A supported desktop browser available to the project's browser-test runner
- The repository's normal local HTTPS or localhost convention
## Tool Discipline
Use `Read`, `Glob`, and `Grep` to locate runtime construction, HMR boundaries, response headers, unit tests, and browser tests. Use `WebFetch` only for current official StackBlitz or WebContainers documentation. Use `Write` or `Edit` for minimal user-requested tests and configuration.
