Captures, masks, compares, and updates screenshot baselines for web and mobile suites, with per-region thresholds and a reviewed-diff rule for every baseline change. Use when a screenshot assertion fails, a baseline needs updating, or visual checks are being added; not for deciding what to verify.
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
# Quality Engineering: Visual Baseline ## **Priority: P1 (HIGH)** ## Capture - One baseline per scenario, viewport, theme, and locale that the plan names; never one baseline per developer machine. Capture in the CI image only; a locally captured baseline is a draft. - Freeze animations and the clock before capture; wait for network idle and fonts loaded. - Name baselines `<screen>-<state>-<viewport>[-dark][-<locale>].png` next to the spec in the tool's snapshot folder. ## Mask, Then Threshold - Mask every dynamic region before comparing: clocks, counters, avatars, ads, maps, third-party embeds, randomised ids. A masked region is compared as a solid block, so a layout shift inside it still fails. - Thresholds are per region and small: text and controls `0.1%` max diff pixels, images and charts `1%`. A suite-wide threshold above `1%` is a disabled check. - Full detail in [Masking and Thresholds](references/masking-and-thresholds.md). ## Classify a Failure …

How to install
mdr add hoangnguyen0403/agent-skills-standard/quality-engineering-visual-baseline@sha256:52c3ed0b3b2d2d73The line at the top of this page pins the label git:20260913.6db6862, 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.
