test-engineer

test-engineer is an agent for coding agents from aizhangdeshuai-cmd/hlskills. It costs 45 tokens per session (1,594 once invoked), scanned A, original, no licence file.

A coding agent focused on planning and improving software tests. TDD, or test-driven development, means writing tests before the code they check; end-to-end tests check complete user workflows.

In plain words
What is it for?
Use it for test plans, writing test cases, integration and end-to-end coverage, flaky-test hardening, and TDD workflows.
Why use it?
It helps address missing test coverage, unreliable tests, and unclear testing strategies. It can also guide work where tests are written as part of the development process.

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 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.

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.
