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 5.1 | $0.00031 | $0.02223 |
| Opus 5 | $0.00015 | $0.01111 |
| Sonnet 5 | $0.00006 | $0.00445 |
| Haiku 4.5 | $0.00003 | $0.00222 |
Grade A, and why
playwright-bdd-analyzer 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 12d 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.

Playwright-BDD Analyzer
Analyze and improve Playwright-BDD/Cucumber test quality, coverage, and maintainability.
When to Use
- Reviewing
.featurefiles for quality issues - Analyzing step definition reusability
- Checking scenario coverage gaps
- Evaluating E2E test execution results
- Assessing test maintainability
Quick Reference
Quality Targets
| Metric | Target | Priority |
|---|---|---|
| Step Reuse Rate | ≥60% | Medium |
| Declarative Scenario Rate | ≥80% | Medium |
| Scenario Independence | 100% | High |
| Happy Path Coverage | 100% | Critical |
| Error Path Coverage | 100% | Critical |
| Boundary Value Coverage | ≥80% | Medium |
| Security Test Coverage | 100% | Critical |
| Tag Coverage | ≥90% | Low |
| Flaky Test Rate | 0% | High |
Declarative vs Imperative Style
# ❌ IMPERATIVE (avoid) - UI details exposed
When user enters "[email protected]" in email field
And user enters "password123" in password field
And user clicks login button
# ✅ DECLARATIVE (preferred) - business intent clear
When user logs in with valid credentials
Flaky Patterns to Avoid
// ❌ Fixed timeout - flaky
await page.waitForTimeout(2000);
// ✅ Explicit wait - stable
await page.waitForSelector('[data-testid="result"]');
// ❌ Text selector - brittle
await page.click('button:has-text("Submit")');
// ✅ Test ID selector - stable
await page.click('[data-testid="submit-button"]');
Analysis Checklist
1. Gherkin Quality
- Scenarios use declarative style (no UI details)
- Each scenario is independent (can run alone)
- Background extracts common preconditions
- Scenario Outline used for similar test cases
- Steps are parameterized where possible
2. Coverage Completeness
For each feature, verify:
- Happy Path - Normal flow works
- Error Path - Error handling works
- Boundary Values - Edge cases covered
- Auth/AuthZ - Permission checks work
- Loading/Error States - UI states handled
- Concurrency - Race conditions handled
- Security - XSS/CSRF/injection prevented
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

playwright-bdd-analyzer is a skill published in the GitHub repository cuongtl1992/vibe-skills (10 stars, last pushed 5mo ago), licensed MIT. It adds 31 tokens to every session and 2,223 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
