Main application building orchestrator. Creates full-stack applications from natural language requests. Determines project type, selects tech stack, coordinates agents.
Project scaffolding templates for new applications. Use when creating new projects from scratch. Contains 12 templates for various tech stacks.
Design thinking and decision-making for web UI. Use when designing components, layouts, color schemes, typography, or creating aesthetic interfaces. Teaches principles, not fixed values.
Automatic quality control, linting, and static analysis procedures. Use after every code modification to ensure syntax correctness and project standards. Triggers onKeywords: lint, format, check, validate, types, static analysis.
Native multi-agent orchestration using Claude Code's Agent Tool. Use when multiple independent tasks can run with different domain expertise or when comprehensive analysis requires multiple perspectives.
Testing patterns and principles. Unit, integration, mocking strategies.

Discover and test everything. Leave no route untested.
Execute these for automated browser testing:
| Script | Purpose | Usage |
|---|---|---|
scripts/playwright_runner.py | Basic browser test | python scripts/playwright_runner.py https://example.com |
| With screenshot | python scripts/playwright_runner.py <url> --screenshot | |
| Accessibility check | python scripts/playwright_runner.py <url> --a11y |
Requires: pip install playwright && playwright install chromium
| Target | How to Find |
|---|---|
| Routes | Scan app/, pages/, router files |
| API endpoints | Grep for HTTP methods |
| Components | Find component directories |
| Features | Read documentation |

Individual UI pieces
| Priority | Tests |
|---|---|
| 1 | Happy path user flows |
| 2 | Authentication flows |
| 3 | Critical business actions |
| 4 | Error handling |
| Practice | Why |
|---|---|
| Use data-testid | Stable selectors |
| Wait for elements | Avoid flaky tests |
| Clean state | Independent tests |
| Avoid implementation details | Test user behavior |
| Concept | Use |
|---|---|
| Page Object Model | Encapsulate page logic |
| Fixtures | Reusable test setup |
| Assertions | Built-in auto-wait |
| Trace Viewer | Debug failures |
| Setting | Recommendation |
|---|---|
| Retries | 2 on CI |
| Trace | on-first-retry |
| Screenshots | on-failure |
| Video | retain-on-failure |
| Scenario | Value |
|---|---|
| Design system | High |
| Marketing pages | High |
| Component library | Medium |
| Dynamic content | Lower |
| Area | Tests |
|---|---|
| Status codes | 200, 400, 404, 500 |
| Response shape | Matches schema |
| Error messages | User-friendly |
| Edge cases | Empty, large, special chars |

| Pattern | Example |
|---|---|
| Feature-based | login.spec.ts |
| Descriptive | user-can-checkout.spec.ts |
| Strategy | Use |
|---|---|
| Per file | Playwright default |
| Sharding | Large suites |
| Workers | Multiple browsers |
| ❌ Don't | ✅ Do |
|---|---|
| Test implementation | Test behavior |
| Hardcode waits | Use auto-wait |
| Skip cleanup | Isolate tests |
| Ignore flaky tests | Fix root cause |
Remember: E2E tests are expensive. Use them for critical paths only.
