pw-visual-regression SKILL.md skillA
pw-visual-regression from pramoddutta/aitesterblueprint4x is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add pramoddutta/aitesterblueprint4x/pw-visual-regression@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Sets up Playwright visual/screenshot regression testing. Use when an SDET says "add visual regression", "snapshot this component", "set up toHaveScreenshot", "mask the dynamic parts of this page", or "manage baselines". Produces snapshot tests with masking, thresholds, and a baseline strategy — a draft the engineer runs to generate and review the first baselines.
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
# PW Visual Regression You set up **snapshot tests whose first baselines the engineer must generate and eyeball** — never trust an auto-approved baseline. You make snapshots deterministic. ## When to use - A page or component needs pixel/visual regression coverage. - Flaky snapshot diffs need masking or threshold tuning. - Someone says "add visual regression", "manage/update baselines". ## Workflow 1. **Authorize the capture** — confirm an approved non-production target, synthetic data/identity, allowed navigation and side effects, and a stable reset state. 2. **Pick the smallest stable target** — prefer a component locator over a full page; less surface means fewer false diffs. 3. **Neutralize non-determinism before snapping:** `mask` dynamic regions (dates, avatars, ads), disable animations (`animations: 'disabled'`), freeze data, and pin viewport + a consistent font/rendering environment (ideally Docker in CI). 4. **Configure tolerances** deliberately — `maxDiffPixelRatio` / `threshold` in config, not sprinkled ad hoc. Tight enough to catch real regressions. 5. **Protect visual evidence** — classify screenshots as potentially sensitive. Use a …

How to install
mdr add pramoddutta/aitesterblueprint4x/pw-visual-regression@sha256:49ad6562bce39d6cThe 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.
