No way to know what else broke
One shared component ripples into pages nobody opened in the PR. Today you find them by hand, if you find them.
Collaborative review
Review UI changes as a team
Every reviewer in one place, human or agent. See exactly what a pull request changed, comment on the exact pixel, accept or deny, and the verdict lands on the PR as a check. So the change gets a real look before it merges, not after it ships.

The old fill was intentional. As an outline the Add to cart button fails our contrast check, can we keep the solid style?

Good catch, that was not intended. Restoring the fill and re-running the check now.
Agents ship UI faster than anyone can review it
Review is the bottleneck now, and its visual part falls through the cracks: code review reads the diff, not the pixels.
Was this change on purpose?
A reviewer cannot tell an intended restyle from a regression, so the real break blends in with the ones you meant.
Caught in production, not in review
Code review reads the diff, not the pixels. The button that went missing gets reported by a customer.
Everything in one place
The change, the conversation, and the decision on one screen, pinned to the pixels that moved. No Slack thread, no separate preview, no lost context.

Flip between side by side, a tinted diff, a spotlight on the change, or a draggable overlay. Whatever the change is, it is impossible to miss.

Decide in one click
Accept, deny, or ignore. One call settles the story across every browser and viewport at once.

The decision lands on the pull request
Every review updates one sticky comment and the commit status on the PR, so the whole team sees where a change stands without opening the dashboard. A denied change keeps the check red and blocks the merge until it is fixed or accepted.
- A single comment, edited in place, with the before and after inline
- The AI judge's intended-versus-regression call folded onto the summary
- Open review threads mirrored onto the PR so nothing gets lost
- The status flips live the moment a reviewer accepts or denies

Your agents review, over MCP
Connect the UI Verify MCP and your coding agent joins the same review. It pulls the changed diffs, reads the notes a designer or QA left, and accepts the intended changes or denies a regression, all attributed to its own key so you can see who decided what.
The judge still makes the deterministic call and your team still owns the merge. The agent handles the grunt work of triage so people review only the decisions that need a human.

● The Button restyle is intended. On pages/Product the button lost its fill,
which matches Mia’s note. Denying that one.
