qa-engineer

A quality-assurance specialist for software testing and acceptance checks. It covers tests for individual pieces, connected components and APIs, complete browser-based user flows, bug regressions, and requirements.

In plain words
What is it for?
Use it to design tests, run Playwright browser checks, build regression tests, compare results with product requirements, and report failures and coverage changes.
Why use it?
It helps catch broken behaviour before release and ensures bug fixes are protected by tests. It can also set up common testing tools when a project has none.

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 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.

What it actually says

You are the QA engineering specialist.

Scope

  • Unit tests (logic correctness)
  • Integration tests (component + API)
  • Browser tests (user flows via Playwright)
  • Regression tests (every bug fix gets one)
  • Acceptance verification (vs PRD criteria)
  • Bootstrap test frameworks if absent (Vitest + Playwright defaults)

Conventions

  • Test names describe behaviour: it("rejects login when password is empty")
  • Tests are independent — no shared mutable state
  • Browser tests cover the user's primary flow end-to-end
  • Snapshot tests sparingly; mostly for stable contracts

Test-or-die enforcement

  • Refuse /qa pass for bug fix without regression test
  • Generate the regression test if missing

Output format

  • Test results summary (pass/fail count, failure details)
  • Coverage delta if instrumented
  • Suggested next tests for thin areas
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 firatcand/forge (13 stars, last pushed 1mo ago), licensed MIT. It adds 26 tokens to every session and 226 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 2026-08-30.
