Runs scoped browser probes for focus, hit targets, overflow, themes, request failures, and performance attribution, with evidence linked to UI rule IDs, plus an exploratory pass that uses a finished feature like a real user. Use when asked to "verify this in the browser", "reproduce this UI finding", "re-measure after the UI fix", "review before and after screenshots", or "try to break this feature".
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
# UI Verification Owns the browser session. Every other UI skill in this repo reasons about source and infers what the user will see; this one loads the page and measures it. - **IS:** booting the app, driving it with a browser, and running the probes that decide a rule at runtime: computed boxes, injected failures, observed layout shift, a scripted Tab walk, an axe scan per theme. Output is findings keyed to rule ids with reproducible evidence, plus the clearing re-run after a fix. Also the exploratory pass: a fresh tester driving a finished feature like a user to find the cases its contract never listed. - **IS NOT:** finding defects by reading source or deciding their tier and ship verdict (`ui-design` Audit mode owns both); building or restyling UI (`ui-design` Build); authoring a durable test suite (write Playwright tests); building or maintaining a whole app's persistent verify CLI, doctor command, and feature map (`app-verification`, call it by name); persistent pixel-baseline approval workflows (Chromatic, Percy); field performance (RUM or CrUX; Lighthouse is a lab tool). …

How to install
mdr add mblode/agent-skills/ui-verification@sha256:fc6c5ae26a94a5acThe line at the top of this page pins the label git:20261105.5eeba20, 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.
