Prove a UI looks right across every state and viewport it has to survive — enumerate the state matrix, make captures deterministic, compare against a baseline captured the same way, and triage every diff. Use before calling a visual change, a style refactor or a redesign done, when running or trusting a screenshot-comparison suite, and when asked whether a screen still looks correct. Not for judging whether a design is good, not for proving controls actually work, and never on its own…
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
# Visual verification
A screenshot is evidence that pixels were produced. It is not evidence that they were produced by
your change, that they are correct, or that anything behind them works. This procedure turns
screenshots into an argument that survives being questioned.
## When this fires
Before reporting a change to appearance as done — CSS, layout, theming, spacing, a component's
visual states, a design-system swap. Also when a visual regression suite reports a diff, or
reports none and someone is about to treat that as proof. It does not fire for changes with no
visual surface, and it does not fire when the question is whether the design is any good.
## Procedure
1. **Derive the surface from the change, not from the app.** List the components and routes the
change can reach. A shared token or a base component reaches far more than the page you edited
— grep the usages before deciding the surface is one screen.
2. **Write the matrix down before capturing anything.** States × viewports × themes:
- states — default, empty, loading, error, long content, truncated content, disabled, focused,
hovered, selected, and whatever this component's own states are

How to install
mdr add nahid-sparktales/agent-dispatcher/visual-verification@sha256:1b4131bd6c05ce36The line at the top of this page pins the label git:20260919.a0d4f55, 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.
