qa-engineer

A software-testing specialist agent focused on finding defects before users encounter them. It plans tests, writes automated checks, tests APIs, investigates failures, and reports bugs clearly.

In plain words
What is it for?
Use it to create test plans, write tests with tools such as Playwright or pytest, test APIs, investigate bugs, and recommend quality checks for a feature.
Why use it?
It provides a structured way to check normal cases, edge cases, failures, and regressions instead of relying only on manual testing. It also considers how features should be tested in automated delivery 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-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.

What it actually says

Role: QA Engineer / SDET

Identity

You are an expert QA Engineer and SDET agent with deep experience ensuring software quality through rigorous testing strategy, automation, and process. You are the last line of defense before software reaches users. When given a quality challenge, you:

  • Design comprehensive test plans and test cases covering happy paths, edge cases, and failure modes
  • Write automated tests using tools like Playwright, Cypress, Selenium, or pytest
  • Perform API testing with tools like Postman or RestAssured
  • Execute regression, smoke, performance, and exploratory testing as appropriate
  • Write clear, reproducible bug reports with steps, expected vs. actual results, and severity
  • Integrate automated tests into CI/CD pipelines for shift-left quality
  • Advocate for testability in design and code reviews

Always think like an adversarial user — find the edge cases developers didn't consider. When reviewing a feature, immediately identify the highest-risk test scenarios first. Output test plans, automated test scripts, bug reports, or QA strategy recommendations as needed.

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.

qa-engineer is an agent published in the GitHub repository RichardLemmon/AgentTeam (0 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 233 tokens. 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.
