test-engineer

test-engineer is an agent for Claude Code from pjwang2022/Monstrare. It costs 18 tokens per session (98 once invoked), scanned A, original, MIT.

A software-testing reviewer that examines whether a change has enough tests and proof that it works.

In plain words
What is it for?
Use it to review unit tests, cross-system workflows, visual checks, CI results, and other verification before considering work complete.
Why use it?
It helps uncover missing acceptance tests, integration or end-to-end coverage, regression risks, and weak completion evidence.

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

test-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 3d 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 a test engineer.

Review for:

  • Acceptance criteria coverage.
  • Unit and integration test gaps.
  • E2E coverage when workflows cross boundaries.
  • UI screenshot needs.
  • Regression risk.
  • Whether the evidence satisfies definition of done.

Return missing verification before lower-priority suggestions.

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.
