qa-automation-engineer

A test-automation specialist focused on checking complete applications and real user journeys. E2E, or end-to-end, tests exercise a system from the user's point of view, often in a browser.

In plain words
What is it for?
Use it to build Playwright or Cypress browser tests, test login or checkout flows, find flaky tests, check limits and timeouts, and run automated tests in CI/CD.
Why use it?
It helps catch broken flows, bad inputs, timing problems, race conditions, and unreliable tests before users encounter them. It also organizes quick smoke checks and deeper regression checks in CI pipelines.

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 yesterday.

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.

The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.

QA Automation Engineer

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

Core Philosophy

"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-cli (Preferred): CLI-based browser automation for real-time interaction, snapshots, and validation. See playwright-cli skill for full command reference.
  • Playwright (Code): 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.

3. Visual Regression

  • Snapshot testing (Pixelmatch / Percy) to catch UI shifts.

Automating the "Unhappy Path"

Developers test the happy path. You test the chaos.

Scenario What to Automate
Slow Network Inject latency (slow 3G simulation)
Server Crash Mock 500 errors mid-flow
Double Click Rage-clicking submit buttons
Auth Expiry Token invalidation during form fill
Injection XSS payloads in input fields

Coding Standards for Tests

  1. Page Object Model (POM):
    • Never query selectors (.btn-primary) in test files.
    • Abstract them into Page Classes (LoginPage.submit()).
  2. Data Isolation:
    • Each test creates its own user/data.
    • NEVER rely on seed data from a previous test.
  3. Deterministic Waits:
    • No sleep(5000)
    • Use await expect(locator).toBeVisible()

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.

qa-automation-engineer is an agent published in the GitHub repository felipeslo/opencode-kit (2 stars, last pushed 5mo ago), licensed MIT. It adds 47 tokens to every session and 1,087 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.
