Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00069 | $0.01517 |
| Opus 5 | $0.00034 | $0.00758 |
| Sonnet 5 | $0.00014 | $0.00303 |
| Haiku 4.5 | $0.00007 | $0.00152 |
Grade A, and why
playwright scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
92% identical to playwright — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Playwright + Next.js Testing Best Practices
Comprehensive testing optimization guide for Playwright with Next.js applications. Contains 43 rules across 8 categories, prioritized by impact to guide reliable, fast, and maintainable E2E tests.
When to Apply
Reference these guidelines when:
- Writing new Playwright tests for Next.js apps
- Debugging flaky or failing tests
- Optimizing test execution speed
- Setting up authentication state reuse
- Configuring CI/CD pipelines for testing
- Testing Server Components and App Router features
- Reviewing test code for reliability issues
Rule Categories by Priority
| Priority | Category | Impact | Prefix |
|---|---|---|---|
| 1 | Test Architecture | CRITICAL | arch- |
| 2 | Selectors & Locators | CRITICAL | loc- |
| 3 | Waiting & Assertions | HIGH | wait- |
| 4 | Authentication & State | HIGH | auth- |
| 5 | Mocking & Network | MEDIUM-HIGH | mock- |
| 6 | Next.js Integration | MEDIUM | next- |
| 7 | Performance & Speed | MEDIUM | perf- |
| 8 | Debugging & CI | LOW-MEDIUM | debug- |
Quick Reference
1. Test Architecture (CRITICAL)
arch-test-isolation- Use fresh browser context for each testarch-parallel-execution- Enable parallel test executionarch-page-object-model- Use Page Object Model for complex pagesarch-fixtures- Use fixtures for shared setuparch-test-production- Test against production buildsarch-cleanup-state- Clean up test state after each test
2. Selectors & Locators (CRITICAL)
loc-role-selectors- Use role-based selectors over CSSloc-data-testid- Use data-testid for dynamic elementsloc-label-selectors- Use getByLabel for form inputsloc-text-selectors- Use getByText for static contentloc-avoid-xpath- Avoid XPath selectorsloc-chained-locators- Chain locators for specificityloc-placeholder-selector- Use getByPlaceholder sparingly

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 2d ago First seen · 116 lines · 69 tokens per session scan A 1c2be543385c
playwright is a skill published in the GitHub repository PyModel/react-frontend-skills (3 stars, last pushed 12d ago), licensed MIT. It adds 69 tokens to every session and 1,517 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 92% identical to playwright, differing in 8 lines, and is treated as a copy.
