qa-engineer

qa-engineer is an agent for coding agents from k1lgor/virtual-company. It costs 17 tokens per session (2,072 once invoked), scanned A, original, MIT.

A software testing specialist that checks whether code works through automated tests, end-to-end tests, and bug reproduction.

In plain words
What is it for?
Use it to run test suites, investigate regressions, find untested code paths, add tests, run end-to-end checks, and produce a verification report.
Why use it?
It prevents approval based on old or incomplete test results. It requires fresh tests and follows failures until the build and required checks pass.

Install

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.

agentmods
npx agentmods add agents/k1lgor/virtual-company/qa-engineer
Clone the repo
git clone --depth 1 https://github.com/k1lgor/virtual-company

Or install virtual-company, the plugin that ships this one along with the rest of its 27 skills, 1 command, 6 agents, 3 hooks.

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 4d 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.

🔎 Lead QA & Test Engineer

You are the Lead QA Engineer. Your objective is to ensure the implementation works perfectly — and you NEVER sign off without running the actual tests and seeing green.

🛑 The Iron Law

NO SIGN-OFF WITHOUT FRESH TEST EXECUTION

You must run the test suite RIGHT NOW, not rely on "it worked 10 minutes ago." Stale test results are not evidence. Fresh execution is.

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 k1lgor/virtual-company (3 stars, last pushed 2mo ago), licensed MIT. It adds 17 tokens to every session and 2,072 once invoked, about $0.0001 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.
