Codebase

Set up and maintain semantic-release based release automation for repositories that need automated versioning, changelog generation, GitHub release creation, release commits, and release workflows on pushes to main, without publishing packages to npm or GitHub Packages. Use when Codex needs to add or update semantic-release, `.releaserc.js`, or GitHub Actions release workflows focused on changelogs and GitHub releases only.

Prepare, publish, and automate releases for npm packages, especially scoped packages that need package.json fixes, publish scripts, npm dry-run checks, `.env`-managed `NPM_TOKEN` handling, npm org token setup, GitHub Actions secrets, semantic-release workflows, npmjs.org publishing, GitHub Packages publishing, GitHub Releases, or release troubleshooting. Use when Codex needs to make a repo publish-ready, verify what npm will ship, configure automated publishing, or diagnose failures involving package contents, registry auth, 2FA, tokens, tags, changelogs, GitHub Actions, or semantic-release.

Add or maintain Playwright testing for web applications, including unit-style Playwright tests, browser E2E tests, separate Playwright configs, npm scripts, GitHub Actions CI wiring, browser installation, localhost web server setup, mock environment variables for auth-dependent apps, ignored test artifacts, and troubleshooting CI failures.

Add, configure, or verify Vercel Web Analytics in web applications using the official `@vercel/analytics` package. Use when Codex needs to enable page-view analytics, integrate the Analytics component into Next.js App Router or Pages Router projects, diagnose missing Vercel analytics traffic, or confirm an existing installation without adding a separate analytics provider.
