Use when creating or refactoring playwright.config.ts, defining projects and dependencies, splitting smoke vs integration runs, setting retries/workers/timeouts, or hardening config for CI. Opinionated defaults and decision rules for config that scales.

Use when testing a localized UI built with i18next and react-i18next, when deciding how to select a control whose text is translated, or when making the i18next setup type-safe so a bad t() key fails the build instead of shipping an empty string. Pairs the locator priority of playwright-locators with the test-id judgment of playwright-testid-strategy for the localized case.
Use when testing shadcn/ui components built on base (`@base-ui/react`) with Playwright, or when a review treats "we use shadcn, so accessibility is handled" as settled. Covers what the primitives give you (real roles, keyboard, focus traps) versus what stays application code (the accessible name), the portal scoping every overlay needs, and the surfaces where a test id hides a missing name.
Use when deciding whether a `data-testid` is justified, reviewing a PR that reaches for test ids, asserting that a conditional element is present or gone, or judging whether an aria-label is a real label or a test hook in disguise. Settles the "default or fallback" question that playwright-locators raises, with the cases where a test id is genuinely the only solution and the anti-patterns that hide accessibility bugs.
Use when building a new UI component or feature with its tests, hardening an existing component for testability, or adding component/e2e coverage. Co-designs accessible markup with role-first selectors so the query that finds an element also proves a real user can reach it, then drives a two-tier test matrix (jsdom component tests + Playwright/axe journeys). Triggers on "build a component", "add tests for X", "write tests", "make this testable", "cover this component".
Use when modelling reusable UI fragments (sidebars, headers, modals, table rows, cards) in Playwright tests, when the same locators appear on multiple pages, or when one feature renders differently across themes/frameworks/A-B variants. The container-rooted component pattern that composes anywhere without ceremony.
Use when a Playwright test fails and you need fast root-cause diagnosis using trace viewer, inspector, console/network evidence, and repeatable repro commands. Focuses on shortest path from failure to permanent fix.

The config file holds the suite's architecture. A weak playwright.config.ts creates slow, flaky suites even when the tests are good.
