Use to actually verify a web change in a real browser instead of assuming it works — click through a flow, catch console errors, check a form submits, confirm a fix on the page. Trigger when a UI change needs proof, a bug only reproduces in the browser, or the user asks to test, check, or screenshot the running app.
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
# Browser Test Loop Code that compiles is not code that works. This is the loop that closes the gap between "the diff looks right" and "the page does the thing". ## Core Behavior Drive a real browser against the running app, assert on what actually rendered, and fix what fails. Never report a UI change as working on the strength of the diff alone. ## Setup Playwright is the default. It installs its own browsers and runs headless in CI. ```bash npm i -D @playwright/test && npx playwright install chromium ``` Start the app first and hold the port — a test suite against a dead server produces a wall of timeouts that tells you nothing: ```bash npm run dev > /tmp/dev.log 2>&1 & npx wait-on http://localhost:3000 ``` ## The Loop 1. **Name the assertion in one sentence.** "After submitting the contact form with a valid email, a success message appears and no console error fires." Vague goals produce vague tests. 2. **Write the smallest script that proves it.** One flow per file. 3. **Run it.** Read the failure, not the summary. 4. **Fix the app, not the test** — unless the test encoded the wrong expectation, in which case say so out loud. …

How to install
mdr add onewave-ai/claude-skills/browser-test-loop@sha256:0c49a983602d96c6The line at the top of this page pins the label git:20260920.97b5147, 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.
