Adversarial reviewer that takes raw Cypress Studio or manually recorded specs and refactors them to idiomatic Cypress: extracts repeated login / navigation flows into custom commands (per docs.cypress.io/api/cypress-api/custom-commands), replaces brittle CSS/class selectors with `data-cy` / `cy.findByRole` equivalents, rewrites fixed `cy.wait(ms)` sleeps as retry-aware assertions or aliased intercepts, and applies the app-action pattern (programmatic state setup instead of UI-driven flows) where appropriate. Use when a recording from Cypress Studio or a live-interaction session lands in a PR; the agent produces team-ready code from the raw recording.

Adversarial reviewer that takes Playwright codegen output (raw recorded test code) and refactors it to idiomatic Page Object Model code - extracts repeated selectors into constants, identifies common interactions worth Page Object methods, replaces brittle CSS selectors with `getByRole` accessibility-first equivalents per the convention, restructures the recorded sequence into AAA-pattern tests. Use after recording a flow with `npx playwright codegen`; the agent produces team-ready code from the raw recording.

Action-taking agent that manages distributed Selenium runs across local Selenium Grid (Docker), Sauce Labs, BrowserStack, and LambdaTest - given a test suite and a target matrix, picks the appropriate provider per matrix combination, generates the per-target capabilities, schedules the run, aggregates results into a per-target verdict matrix. Use when a Selenium suite needs to run across many browser/OS combinations and the team doesn't want to manage the orchestration manually.

Builder agent that takes a user story or test-case row plus a target framework (Playwright / Cypress / Selenium / WebdriverIO) and outputs an E2E test scaffold with explicit `// TODO` placeholders for selectors and assertions - never inventing locators, never asserting against fabricated DOM. Sibling of `playwright-codegen-reviewer` (which refines existing codegen output, downstream); this agent is upstream - it generates the scaffold to be reviewed. Always recommends `assertion-quality-reviewer` and `e2e-selector-quality-critic` (in qa-test-review) and `ai-test-shallow-coverage-critic` (in qa-ai-assisted) as required downstream gates. Use when starting a new E2E test from a story or matrix row and the team wants a clean skeleton instead of dropping into raw codegen.

Action-taking agent that reads a target web app project (`package.json`, `playwright.config.*`, `cypress.config.*`, `wdio.conf.*`, `nightwatch.conf.*`, existing E2E directory) and recommends ONE E2E framework - Playwright, Cypress, Selenium, Puppeteer, TestCafe, WebdriverIO - plus the cloud runner (BrowserStack / Sauce Labs / LambdaTest) when cross-browser matrix coverage is needed. Distinct from `qa-process/framework-choice-advisor` (reference catalog laying out trade-offs in prose). Use when starting a new E2E test project and the team has not yet committed to a framework.

Author and run E2E tests on BrowserStack Automate - cloud grid covering 3000+ real device + browser combinations. Covers BROWSERSTACK_USERNAME + ACCESS_KEY auth, hub URL https://hub-cloud.browserstack.com/wd/hub, W3C capabilities + bstack:options (projectName, buildName, sessionName), BrowserStackLocal for testing against localhost / internal environments, parallel session limits, and CI integration. Use for cross-browser regression on real devices + browsers - distinct from qa-web-e2e/playwright-testing (single-runner) and qa-compatibility/browser-matrix-runner (bundled engines only).

Authors Cypress E2E tests - `npm install cypress`, `cypress.config.ts` setup, `cy.*` command chains, automatic-waiting commands, time-travel debugger via Cypress GUI, custom commands for reusable patterns, Cypress Cloud for parallel/recording. Per Cypress''''s positioning: "fast, consistent and reliable tests that are flake-free" via in-browser execution architecture.

Orients a junior engineer to web E2E testing in the qa-web-e2e plugin - maps the available skills and agents, routes framework choice through the right agent, and walks the three entry-point skills for first-time setup. Use when a junior engineer is new to web E2E and does not know where to start in this plugin.

Author and run E2E tests on LambdaTest - cloud grid for cross-browser + real-device testing with W3C WebDriver, Cypress, Playwright, and Appium support. Covers LT_USERNAME + LT_ACCESS_KEY auth, hub URL hub.lambdatest.com/wd/hub, W3C capabilities + LT:Options dict (build, name, project, smartUI, network, console, video, tunnel), LambdaTest Tunnel for internal apps. Use for cross-browser regression with LambdaTest as the cloud grid; complements BrowserStack + Sauce Labs.

Authors Playwright E2E tests across Chromium, Firefox, WebKit - `npm init playwright@latest` scaffolding, `playwright.config.ts` projects per browser/device, accessibility-first locators (`getByRole`/`getByLabelText` per the e2e-selector convention), Page Object pattern, trace viewer for debugging, parallel + sharded execution, HTML reporter for CI. Per Playwright''''s docs: "an end-to-end test framework for modern web apps. It bundles test runner, assertions, isolation, parallelization and rich tooling.
