Test Engineer

Test Engineer is an agent for coding agents from andreaswasita/copilot-agents-dojo. It costs 15 tokens per session (248 once invoked), scanned A, original, MIT.

An agent for planning, writing, maintaining, and automating software tests. It covers unit tests for individual pieces, integration tests for connected parts, and end-to-end tests for complete user flows.

In plain words
What is it for?
Use it to create test strategies, write and maintain tests, improve coverage, debug failures, and set up automated testing in build and deployment pipelines.
Why use it?
It provides a structured way to find test gaps, investigate failures, and keep validation reliable as the code changes.

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 5d 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.

✅ Debug and fix test failures
✅ Automate testing workflows

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.
