• GitHub Check: Run E2E Tests

x_docs/own/WORDS.md (1)

130-132: Approved. Documentation addition is clear and concise.

The new "Misc" section properly documents the theme-aware background implementation approach for auth pages.

.gitignore (1)

44-45: Approved. Gitignore entries are properly formatted.

The addition correctly ignores temporary documentation and maintains consistency with existing entries.

README.md (1)

21-21: Approved. README table update accurately reflects Lefthook configuration.

The description correctly documents that Lefthook now runs build validation and E2E tests on pre-push.

.github/workflows/test-e2e.yml (1)

47-59: Approved. Clerk environment variables properly configured for CI workflow.

Both build and test steps have appropriate Clerk credentials sourced from secrets. The variable names (E2E_TEST_EMAIL, E2E_TEST_PASSWORD, E2E_TEST_OTP) align with @clerk/testing requirements.

components.json (1)

21-23: Approved. Clerk registry properly configured for shadcn/ui integration.

The registry entry enables Clerk components to be installed via the shadcn/ui CLI, supporting the Clerk authentication UI implementation.

.github/workflows/test-e2e-vercel.yml (1)

78-83: Approved. Clerk environment variables consistent with test-e2e.yml.

Vercel preview E2E tests have the same Clerk credentials as local tests, ensuring consistent authentication testing across deployment environments.

lefthook.yml (1)

43-48: Approved. Pre-push build hook properly configured for Next.js 16 PPR compatibility.

The sequential build check catches static generation errors (particularly missing Suspense boundaries around async components like ClerkProvider) before E2E tests run. The parallel: false setting correctly prevents race conditions with file locks during the build process.

playwright.config.ts (1)

59-105: Global setup project wiring for Clerk looks sound

Using a dedicated setup project with testMatch: /global\.setup\.ts/ and adding dependencies: ["setup"] for browser projects is a clean way to guarantee Clerk initialisation runs once before the rest of the suite, especially with fullyParallel: true. This aligns well with Playwright’s project-dependency model.

Please double-check against the current Playwright docs that dependencies semantics have not changed in your installed Playwright version, to ensure setup always runs before any auth-dependent tests.

app/old.globals.css (1)

327-355: Removal of !important around the MDX editor toolbar improves cascade control

Dropping !important from the toolbar background and related styles while keeping explicit colours should make these rules easier to override from theme-specific layers, without changing the intended appearance. The .active-theme filter remains focused and self-contained.

x_docs/own/setup-clerk-secrets.md (1)

1-112: Clear, end-to-end documentation for Clerk E2E setup

This document gives a coherent walkthrough of local, GitHub Actions, and Vercel preview configuration, with a sensible separation between app runtime secrets (on Vercel) and test credentials (in GitHub Secrets). The explanation of how clerkSetup() / setupClerkTestingToken() work, plus the troubleshooting section, should make maintaining the auth smoke tests straightforward.

.claude/settings.json (1)

2-85: Permissions updates maintain good safety boundaries whilst enabling new tooling

Adding the playwright-skill marketplace entry and allowing extra Playwright and Vercel-related Bash/WebFetch commands is useful for this repo’s workflow, and keeping "deny": ["Read(**/.env)", "Read(**/.envrc)"] preserves an important guardrail around environment secrets. The remaining allowed commands are operational and diagnostics-oriented, which is appropriate.

app/globals.css (1)

1-52: Clerk shadcn theme import is well-placed; watch for variable collisions

Importing @clerk/themes/shadcn.css alongside your Tailwind and animation layers centralises global styling and keeps Clerk’s components visually aligned with the rest of the shadcn-based UI. With it imported after tailwindcss and tw-animate-css, Clerk’s styles should layer on cleanly.

It is worth sanity-checking in the browser that Clerk’s theme does not unintentionally override any of your own CSS variables (for example font or colour tokens) outside Clerk components, especially in dark mode.

next.config.ts (1)

10-13: typedRoutes is a good safety net for routing; ensure existing paths conform

Enabling typedRoutes: true is a solid move: it will surface typos and invalid hrefs at build time without needing a separate routes constants module. Just be aware it can flag any ad hoc string routes that do not correspond to real files (including unusual groupings like (auth) and catch-all segments), so it is worth running a full type-check to confirm all existing Link/router.push usages type-check cleanly.

e2e/homepage.spec.ts (1)

3-6: Title assertion update makes the homepage smoke test more robust

Using a case-insensitive regex /DevFlow/i for the title assertion reduces brittleness to minor casing changes in the document title while still checking the key branding string is present.

e2e/global.setup.ts (1)

1-10: Clerk global setup is correctly integrated with Playwright’s test runner

Aliasing test as setup, configuring setup.describe.configure({ mode: "serial" }), and defining a single "global setup" test that awaits clerkSetup() is idiomatic for project-based global setup in a fullyParallel suite. This should ensure the Clerk Testing Token is initialised once before dependent projects run.

Please confirm against the current @clerk/testing/playwright documentation that no additional teardown or configuration steps are recommended for your version (for example, explicit cleanup of testing state), and that all required CLERK_* and E2E_TEST_* variables are present in CI.

app/(auth)/sign-in/[[...sign-in]]/page.tsx (1)

1-12: Sign‑in page implementation looks sound

Async pattern with connection() and the centred <SignIn /> wrapper is straightforward and consistent with the rest of the auth flow; no issues from my side.

app/(root)/layout.tsx (1)

1-12: Root group layout composition is clean

Navbar-first composition with children afterwards is clear and matches the overall layout structure; nothing blocking here.

components/navigation/theme-toggle.tsx (1)

15-27: Theme toggle size adjustments are fine

Shrinking the placeholder, button, and icon keeps behaviour unchanged while likely improving visual balance in the navbar; no further changes needed.

app/(auth)/layout.tsx (1)

1-9: Auth layout background wrapper looks appropriate

Full‑height <main> with light/dark background imagery cleanly scopes styling for all auth routes; implementation looks good.

proxy.ts (1)

1-12: Align proxy.ts export with the documented Next 16 proxy pattern

CLAUDE.md says that with Next.js 16 we should move to proxy.ts and export proxy() rather than middleware(), but this file currently does a default export of clerkMiddleware(). That may still work, but it is worth confirming against the official Next 16 proxy docs and our own template guidelines.

If we do want a named proxy entry point, a minimal wrapper that keeps Clerk’s factory usage could look like:

import { clerkMiddleware } from "@clerk/nextjs/server";

const handler = clerkMiddleware();

export function proxy(request: Request) {
  return handler(request);
}

export const config = {
  matcher: [
    "/((?!_next|[^?]*\\.(?:html?|css|js(?!on)|jpe?g|webp|png|gif|svg|ttf|woff2?|ico|csv|docx?|xlsx?|zip|webmanifest)).*)",
    "/(api|trpc)(.*)",
  ],
};

Please verify which export shape Next 16 expects here and whether we want to standardise on this proxy function pattern.

components/clerk-provider.tsx (1)

1-22: The review comment is incorrect. Spreading undefined in JavaScript does not throw a TypeError—it is silently ignored. The existing code works correctly:

appearance={{
  theme: shadcn,
  ...appearance,  // Safe when appearance is undefined
}}

When appearance is undefined (as in the app/layout.tsx usage at line 34), the spread operator simply contributes no properties, leaving only { theme: shadcn }. This is valid JavaScript and poses no runtime risk.

The proposed fix using ...(appearance ?? {}) is unnecessary and changes nothing functionally.

components/navigation/navbar/index.tsx (1)

13-52: LGTM! Clean layout implementation.

The refactoring from grid to flexbox with absolute positioning for the centered search placeholder is a solid approach. The flex layout provides better control for the three-section navbar structure (logo, centered search, auth controls).

e2e/auth.spec.ts (3)

8-11: LGTM! Appropriate handling of browser-specific flakiness.

The WebKit skip with clear documentation is a pragmatic approach to handling timing issues with Clerk's OTP modal. The comment provides good context for future maintainers.

---

12-24: LGTM! Robust sign-in flow with accessible selectors.

The test properly sets up Clerk testing context and uses semantic role-based selectors, which makes the test resilient to styling changes whilst ensuring accessibility compliance.

---

41-52: LGTM! Complete authentication cycle coverage.

The test properly verifies both authenticated and unauthenticated states, with appropriate timeouts for redirects. The sign-out flow through the user menu ensures the full authentication lifecycle is tested.

x_docs/own/flex_grid_layout.md (1)

1-349: LGTM! Excellent documentation following British English conventions.

This documentation provides comprehensive coverage of flexbox, grid, and layout concepts with clear examples and visual diagrams. The British English spelling ("organises", "centre", "centred") correctly follows the coding guidelines for the project.

The static analysis hints suggesting Oxford spelling can be safely ignored—British English is the documented standard for this codebase.

app/layout.tsx (1)

18-25: LGTM! Metadata improvements.

The title capitalisation correction, improved description, and favicon addition are all solid improvements to the site metadata.

• app/(auth)/sign-up/[[...sign-up]]/page.tsx (1 hunks)
• app/layout.tsx (2 hunks)

.claude/commands/coderabbit.md (1)

15-15: Consistent file naming update with clarity improvement.

The changes rename the output file from z_comment.md to z_rabbit_comment.md across the command documentation (lines 15, 18, 24), and add explicit guidance to write to the project root rather than /tmp/. This prevents potential execution errors and improves file discoverability. No remaining references to the old filename exist in the codebase.

app/(auth)/sign-up/[[...sign-up]]/page.tsx (1)

1-57: Sign-up page implementation looks correct and consistent with the sign-in flow

• Server component without "use client" matches the Clerk/Next.js pattern and project guideline.
• await connection() is in place to force dynamic rendering as per the PPR/Next.js 16 setup.
• Two-column layout is clear and responsive; right-hand <SignUp /> usage is straightforward.
• Lucide icons are now marked aria-hidden="true", resolving the earlier accessibility nit so screen readers focus on the text.

If you have not already, please re-run the Clerk E2E auth flow against this page (including mobile viewport) to confirm layout, theming, and the connection() behaviour match expectations in your deployment environment.

app/layout.tsx (2)

2-17: Geist font configuration and usage look sound

The Geist and Geist_Mono setup with CSS variables and the subsequent use on the <body> classes are consistent and idiomatic for the current Next.js font API. No changes needed here.

---

19-24: Metadata update is clear and consistent

The revised metadata (title capitalisation, streamlined description, and explicit favicon icon path) is coherent and aligns with the overall branding. No issues from a code or content perspective.
