Implements visual regression testing with screenshot comparison, diff detection, and CI integration using Playwright or Chromatic. Use when users request "visual testing", "screenshot testing", "UI regression", "visual diff", or "Chromatic setup".
Detect unintended visual changes in UI by comparing screenshots across versions. Use for visual regression, screenshot diff, Percy, Chromatic, UI testing, and visual validation.
Canvas/DOM parity testing for the foreignObject serializer. Use when comparing the SVG foreignObject render path against the native Blink canvas path, writing pixel-diff tests, or hunting canvas vs DOM rendering inconsistencies.
Use this skill whenever reverse-engineering a Sketch file (or Figma export with similar shape) into pixel-perfect React + CSS — covers the iteration mental model, tree reconstruction, layout inference algorithms, geometry math, visual-regression diffing, and the style/typography/path conversions that make "improvement without regression" enforceable. Trigger even if the user doesn't explicitly mention "algorithms" but is converting a design source into web code, building a design-to-code pipeline, or struggling to make incremental fidelity improvements without breaking previously-converted output.
Operate Argos visual testing from the terminal with the `argos` CLI — inspect builds and snapshot diffs, submit reviews, post comments, ignore flaky test changes, fetch analytics, upload screenshots, and manage CI builds. Use whenever running `argos` commands or working with Argos builds, snapshots, flakiness, or visual-regression reviews from a shell, script, or CI pipeline. Load before running `argos` — it covers the token model and JSON output contract that prevent silent failures.
Compare saved or live app screenshots with the argent screenshot-diff tool. Use when testing visual regressions, before/after UI comparisons, screenshot diff checks, visible layout, spacing, color, typography, clipping, overflow, text rendering, or image/icon rendering changes.
[INTERNAL TEMPLATE] Visual evidence capture and regression testing protocol. Called by agent-browser orchestrator.
Game QA testing with Playwright — visual regression, gameplay verification, performance, and accessibility for browser games
Expert in end-to-end testing with Playwright, the modern cross-browser testing framework. Specializes in test generation, page object patterns, visual regression testing, and CI/CD integration. Handles complex testing scenarios including authentication flows, API mocking, and mobile emulation.
Playwright E2E testing expert for browser automation, cross-browser testing, visual regression, network interception, and CI integration. Use for E2E test setup, flaky tests, or browser automation challenges.
Iterative frontend development loop using Meticulous for per-step visual validation. Use when implementing a multi-step frontend change and want to catch visual regressions and unintended side effects at each step, before the final cloud test run.
QA web testing skill using Chrome DevTools MCP tools for visual regression testing, responsive breakpoint validation, and CSS layout debugging. Use this skill whenever the user asks to "test a page", "check breakpoints", "verify responsive layout", "QA this page", "test CSS at different viewports", "check for layout bugs", "verify the fix", or wants to visually inspect a web page at specific viewport widths. Also triggers when the user provides a URL and asks to take screenshots, compare layouts, or inspect element dimensions. Works with any Chrome DevTools MCP-connected browser session on localhost or staging environments.
