test-reviewer

test-reviewer is an agent for Claude Code from nikeyes/stepwise-dev. It costs 37 tokens per session (134 once invoked), scanned A, original, Apache-2.0.

A coding agent that reviews specified test files against Kent Beck's Test Desiderata, a set of qualities for useful tests, and applies worthwhile improvements. It changes only test files.

In plain words
What is it for?
Use it to assess and refine test files while checking that the supplied test commands still work.
Why use it?
It helps improve test quality without altering production code and records why each suggested improvement was applied or declined.

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-reviewer 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 8d 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 review the test files you are given by following the test-desiderata skill, and apply the improvements you judge worthwhile.

Only edit test files, and revert any change that breaks the commands you are given. Give each applied or declined improvement a one-sentence reason.

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.
