Catch unintended visual drift between prototype iterations with deterministic screenshot diffs. Use when iterating on a prototype, before review handoff, or before promoting an SPA prototype to a real build. Default engine is Playwright `toHaveScreenshot` with masking, threshold, and per-OS baselines. Includes Chromatic / Percy guidance for hosted alternatives.
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 Regression > WHEN: A prototype is iterated more than once, or before declaring a prototype review-ready. This skill snapshots the key screens at the canonical breakpoints, diffs new builds against an approved baseline, and fails the audit if drift is unintended. Default engine is Playwright; managed services (Chromatic, Percy, Applitools) are listed for teams that prefer hosted review queues. ## When to Use This Skill - Iterating a prototype where each change can shift unrelated screens - Hardening a working SPA prototype that will inform a production build - Catching CSS regressions from token or theme changes - Reviewing a PR that touches global styles or shared components Visual regression complements axe (a11y) and Lighthouse (performance). It does not replace either. ## Authoritative Sources | Source | What it covers | |--------|----------------| | Playwright Test, Visual comparisons | `toHaveScreenshot`, masking, threshold | | Storybook + Chromatic docs | Component-level visual review | | BrowserStack Percy docs | Hosted DOM snapshot + diff | | Applitools Eyes docs | AI-driven layout-aware diff | …

How to install
mdr add jnpiyush/agentx/visual-regression@sha256:8f73c828b62e4dd6The line at the top of this page pins the label v1.0.0, 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.
