How it works

Reflow coordinates end-to-end test runs that capture snapshots and compare them. A functional assertion can pass while a control disappears, a label changes, or a layout clips. Your agent inspects the exact before and after evidence against the intended change to determine what is in scope and what needs attention.

A PR meant to update invitation copy also removes the role selector. Your agent flags the unexpected removal, links the snapshots, and explains why it appears outside the intended scope.

Before and after

Inspect the original screenshots alongside the comparison to decide whether each change was intended.

Explicit visual checks

A snapshot checkpoint without an approved baseline is new. Baseline approval is explicit and separate from merging a pull request.

Share selected captures

Your agent can assemble selected captures into a walkthrough for the reviewer.

A copy change removed the role selector.

This example compares the invitation screens and shows the agent’s finding about the missing control.
