Independent Playwright E2E test author for a single use case. Reads only the use case specification and frontend design — never implementation reasoning — so tests validate what was designed, not what was built. Follows playwright-test/SKILL.md as its binding operating manual.

Runs a comprehensive implementation audit for a delivered use case. Checks Definition of Done, i18n completeness and correctness, error message i18n, accessibility, visual fidelity against the design, and loading/error states. Run after /deliver-use-case or before /sprint-complete for a quality deep-dive. Results are advisory — Critical and Major findings should be fixed; Minor findings are observations.

Runs oxlint and oxfmt on TypeScript/JavaScript files to fix lint errors, enforce cyclomatic complexity limits, and apply consistent formatting. Use when the user asks to "lint", "format code", "run code quality checks", or mentions code quality, formatting, or static analysis.

Orchestrates the full per-use-case delivery pipeline: verifies spec and design exist, implements the use case, writes E2E tests, and evaluates coverage against the spec. Iterates automatically until quality gates pass. Specification and design must exist beforehand via /sprint-prepare, /use-case-spec, or /design-screens. This skill must only be invoked explicitly via /deliver-use-case or by /sprint-deliver — never inferred from user messages.

Implements use cases and fixes bugs by creating Next.js pages, components, API route handlers, and server actions. Use when the user asks to "implement a use case", "fix a bug", "build the UI", "create an API endpoint", "write a page", or mentions Next.js implementation, App Router, server actions, or full-stack implementation.

Creates Playwright browser-based end-to-end tests for Next.js pages covering complete user journeys from start to finish. Use when the user asks to "write Playwright tests", "create e2e tests", "write integration tests", "test in the browser", or mentions end-to-end testing, browser tests, UI integration tests, or Playwright for Next.js.
