test-visual-regression SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
test-visual-regression from kensaurus/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add kensaurus/skills/test-visual-regression@git:20260923.68c095ePins git:20260923.68c095e in mdr.lock. Pin the fingerprint instead.

Set up Playwright screenshot baselines and CI diffing so UI changes fail pixel by pixel instead of by eye. Use when "add visual regression tests" or "catch UI regressions". Functional clicks → test-playwright.
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
# test-visual-regression — Screenshot baselines that stay green **Degree of freedom: MIXED** — what to baseline `[HIGH freedom]`; determinism loop and 3× clean runs `[LOW freedom — run exactly]`. playwright-cli / project runner — never Playwright MCP. Establish a screenshot baseline for important UI states and wire diffing so unintended visual change fails CI. **Functional tests prove the button works; visual tests prove it didn't move, shrink, lose styling, or overlap the next element.** Use **playwright-cli** (`npx --yes @playwright/cli@latest`) and the project's Playwright test runner — never Playwright MCP. Read `protocol-browser-anti-stall` before any headed session. ## This skill vs neighbors | Skill | Owns | |---|---| | **test-visual-regression** (this) | Pixel baselines + CI diff artifacts | | `test-playwright` | Drive the app like a user; fix functional pain | | `audit-responsive` | Find linearized layout; this *locks* the fix | | `audit-ui-states` | Design empty/error states; this *locks* them | | `audit-uiux-design-system` | Token/component compliance (not screenshot CI) | | `test-qa` | Exploratory CRUD QA | ## How to reason …

How to install
mdr add kensaurus/skills/test-visual-regression@sha256:57ad61f92cd7635aThe line at the top of this page pins the label git:20260923.68c095e, 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.
