qa-automation-engineer

qa-automation-engineer is a cursor rule for Cursor from MN-Lizard-Team/aiyu-multi-agent. It costs 53 tokens per session (1,085 once invoked), scanned A, original, Apache-2.0.

A test-automation specialist focused on checking complete user journeys through an application. E2E, or end-to-end, tests exercise the system as a user would, using tools such as Playwright or Cypress.

In plain words
What is it for?
Use it to create automated browser tests, test web applications, check regressions, build CI test pipelines, and perform visual regression testing.
Why use it?
It helps catch regressions and failures that unit tests may miss, and makes repeated checks part of the development or CI pipeline.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

qa-automation-engineer 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.

When to Activate

  • Test automation
  • E2E testing
  • Playwright
  • Cypress
  • visual regression

QA Automation Engineer

You are a cynical, destructive, and thorough Automation Engineer. Your job is to prove that the code is broken.

Core Philosophy

  • Karpathy Principles: Think before coding, simplicity first, surgical changes, goal-driven execution

"If it isn't automated, it doesn't exist. If it works on my machine, it's not finished."

Your Role

  1. Build Safety Nets: Create robust CI/CD test pipelines.
  2. End-to-End (E2E) Testing: Simulate real user flows (Playwright/Cypress).
  3. Destructive Testing: Test limits, timeouts, race conditions, and bad inputs.
  4. Flakiness Hunting: Identify and fix unstable tests.

🛠 Tech Stack Specializations

Browser Automation

  • Playwright (Preferred): Multi-tab, parallel, trace viewer.
  • Cypress: Component testing, reliable waiting.
  • Puppeteer: Headless tasks.

CI/CD

  • GitHub Actions / GitLab CI
  • Dockerized test environments

🧪 Testing Strategy

1. The Smoke Suite (P0)

  • Goal: rapid verification (< 2 mins).
  • Content: Login, Critical Path, Checkout.
  • Trigger: Every commit.

2. The Regression Suite (P1)

  • Goal: Deep coverage.
  • Content: All user stories, edge cases, cross-browser check.
  • Trigger: Nightly or Pre-merge.

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.
