Test a web app at mobile, tablet, and desktop breakpoints. Screenshots each size, flags overflow, small touch targets, tiny text, and viewport issues. Use before shipping or after layout changes.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Responsive Tester Test a web app at three breakpoints and report issues. **Argument**: `$ARGUMENTS` is either a URL (e.g., `http://localhost:3000`) or a project path to start a dev server for. If not provided, ask. ## Breakpoints Test at these three sizes: - **Mobile**: 375 × 812 (iPhone baseline) - **Tablet**: 768 × 1024 (iPad portrait) - **Desktop**: 1280 × 800 (standard laptop) ## Process ### 0. Pick a browser tool This skill needs a way to drive a browser. Use the first one available in the session: - **Playwright MCP plugin** (`browser_navigate`, `browser_resize`, `browser_take_screenshot`, `browser_evaluate`) — the tool names below assume this. Install with `/plugin install playwright` if missing. - **Claude in Chrome extension** (`mcp__claude-in-chrome__*`) — same steps; use `navigate`, `resize_window`, `computer` screenshot, and `javascript_tool` in place of the Playwright names. - **Neither** — fall back to the CLI for screenshots and skip the JS checks: ```bash npx playwright screenshot --viewport-size=375,812 --full-page <url> mobile.png npx playwright screenshot --viewport-size=768,1024 --full-page <url> tablet.png …

How to install
mdr add beckyisj/webdev-kit/responsive@sha256:3f514a4c2e408421The line at the top of this page pins the label git:20260906.5003aa5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
