qa-automation-engineer

qa-automation-engineer is a skill for Codex from lsantosweb/codex-agents-skills-kit. It costs 34 tokens per session (371 once invoked), scanned A, original, MIT.

A testing guide for automated browser and end-to-end checks using tools such as Playwright or Cypress.

In plain words
What is it for?
Use it to build smoke tests, regression suites, visual checks, CI test pipelines, and automated reproductions of bugs.
Why use it?
It helps catch broken user journeys, error cases, permission problems, and flaky tests before changes reach users.

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 8d 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.

What it actually says

When to use

Use this skill for:

  • Playwright or Cypress setup
  • end-to-end testing of critical flows
  • CI test pipeline setup
  • regression suites
  • visual regression
  • reproducing bugs through automation
  • investigating flaky tests

Core operating rules

  • If it is not automated, it is not protected.
  • Prefer stable assertions over sleep-based waiting.
  • Test the unhappy path, not just the happy path.
  • Isolate test data per scenario whenever possible.
  • Keep smoke tests fast and regression tests deeper.
  • Page objects or equivalent abstractions are preferred for reusable flows.

Testing priorities

Smoke suite

  • login or auth entry
  • primary user flow
  • one business-critical transaction

Regression suite

  • edge cases
  • error states
  • permission boundaries
  • cross-browser or device coverage when relevant

Destructive scenarios

  • slow network
  • 500 responses
  • rage clicks / duplicate submission
  • session expiry mid-flow
  • bad input or injection attempts

Workflow

  1. Identify the highest-risk user journeys.
  2. Define what belongs in smoke vs regression.
  3. Implement tests with deterministic waits.
  4. Wire tests into CI when requested.
  5. Report failures with reproduction context.

Mandatory checks

  • no arbitrary sleeps when an explicit assertion can be used
  • selectors are resilient
  • tests do not depend on previous test state
  • CI command is documented if pipeline work is included

Output format

Report:

  • flows covered
  • framework chosen and why
  • files changed
  • how to run tests locally and in CI
  • remaining coverage gaps
Changes

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.
