Tests acceptance criteria and edge cases as an end user in a real browser (Chrome DevTools MCP, Playwright or the browser tool of the environment), then writes a report with findings. Use it when the user explicitly asks for browser testing, end-user testing, manual QA, "test it like a user", UI validation, or testing with Chrome DevTools, and in an unattended run (unattended-run) when the agent decides that a change with a user interface needs it. Do not open a browser on your own initiative…
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 acceptance testing The user decides when a browser opens. If they asked for this skill, go ahead. In an unattended run the agent decides in their place: open it when the change has a user interface that the acceptance criteria describe, and log the choice as a `Q-` entry. If a browser tool fails, do not switch to another browser tool without asking; in an unattended run, log the switch as a `Q-` entry instead. ## Setup 1. Start the app in an isolated environment with its own port and data (`.scratchpad/<slug>/manual-env.sh`). If the app has sign-in, create test accounts there; keep credentials in the helper, not in chat messages. 2. Choose the browser tool. Prefer the Chrome DevTools MCP. Load the browser tools you need before you start (navigate, snapshot, screenshot, click, fill, fill form, evaluate script, console messages, network requests, emulate, resize). If the environment has no DevTools MCP but has Playwright and a browser (common in containers and cloud sessions), write one script in `.scratchpad/<slug>/scripts/` that drives the same checks. Record console messages, network status codes and screenshots in `.scratchpad/<slug>/shots/`. This is the tool… …

How to install
mdr add webreactiva/yesyak/browser-acceptance-testing@sha256:27f2a1dde3759adcThe line at the top of this page pins the label git:20261017.b634987, 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.
