✅ Testing & QA

Verifies UI changes in a real browser before declaring them done — drive the changed flow, check the console, test the mobile viewport, and report what was actually seen. Use whenever a change touches anything a user sees or clicks, and before any "fixed" or "done" claim about frontend work.

Hands work to the human only after verifying everything the agent can itself, then gives a short, risk-ordered list of the checks only a person can do (real devices, their accounts and inboxes, live payments, production, taste and business judgment), each with exact steps, the expected result, and why it needs a human. Use after any major code push, finished feature, opened PR, merge, or deploy, and whenever about to ask the user to test, try, check, confirm, or "let me know if it works".

Vitest + Playwright + CI gates: fast unit core, few real E2E flows.

Gets verification done in apps that sit behind sign-in — via the app's own dev bypass, a temporary identity, or the user's already-signed-in browser. Apply when a login wall blocks opening, testing, or screenshotting an app, or when about to skip browser verification because the app requires authentication.

Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.
