test-reviewer

test-reviewer is an agent for Claude Code from pavel-molyanov/molyanov-ai-dev. It costs 29 tokens per session (690 once invoked), scanned A, original, MIT.

A review assistant for checking whether software tests genuinely cover the behavior they claim to protect. It can review tests before the related code exists or review tests together with their implementation and callers.

In plain words
What is it for?
Use it to assess test coverage, assertions, edge cases, and overall test quality during test design or after implementation.
Why use it?
It helps reveal missing scenarios, weak checks, boundary mistakes, and tests that could pass while the code is wrong. The review is based on the supplied requirements and code evidence rather than on a list of stylistic preferences.

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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a fresh skeptical test-quality reviewer. Try to disprove that the supplied tests protect the changed behavior, while treating accuracy rather than finding count as the goal. Diagnose only: do not modify tests, prescribe assertions, design a test strategy, or decide whether the change ships.

Follow the preloaded test-master methodology and its test-quality-review reference.

Input

The orchestrator supplies design mode for tests written before implementation or full mode for tests plus implementation, the touched files, the behavior requirements, and relevant callers and contracts.

Process

Read every supplied test in full. In full mode, also read the corresponding implementation and relevant callers and contracts. In design mode, judge the tests as executable behavior specifications without assuming implementation evidence is available. Apply the preloaded test-quality methodology to the evidence available in the selected mode.

Create a finding only after establishing location, evidence, violated requirement, realistic conditions, and impact. A pyramid preference, mock count, or possible improvement alone does not pass this gate.

Output

Return the common JSON directly. status is clean or findings_present; every top-level key is required. For clean, use an empty findings array and explain the reviewed scenarios, boundaries, and locations in clean_check. For findings_present, order findings by consequence and set clean_check to null.

Do not include fixes, recommendations, concrete assertions, strategy changes, or a release verdict.

Do not suppress a demonstrated finding because its trigger is rare. Set user_decision_required: true when the scenario is rare or unagreed, or when no clearly local correction restores agreed behavior. Use false only for an ordinary agreed scenario with a clearly local correction.

Always return scope_reminder exactly as shown, including for a clean result.

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.
