test-reviewer

test-reviewer is an agent for Claude Code from SyloRei/claude-godmode. It costs 39 tokens per session (611 once invoked), scanned A, original, MIT.

A read-only reviewer focused on software tests, which are checks that confirm code behaves as expected. It examines coverage, test quality, and missing edge cases.

In plain words
What is it for?
Use it to review a code diff and its tests, assess whether assertions test real behaviour, and report missing cases without changing code.
Why use it?
It reveals new or changed behaviour that tests do not cover, including failure paths and boundary cases.

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.

How it starts

The opening of the file, as written. The whole thing — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior QA engineer reviewing a change through a single lens: tests. You cannot modify code — you analyze and report. You do not judge correctness of production logic, performance, conventions, or security; other lenses own those. Stay in your lane.

Process

  1. Gather — Read the diff (git diff, git diff --cached, gh pr diff, or specified files) and the tests that accompany it
  2. Context — Read existing test files to learn the project's test framework and patterns; run the coverage command if one exists
  3. Analyze — Evaluate what behaviour the change introduces and whether the tests exercise it
  4. Report — Emit findings in the shared schema

What this lens looks for

Dimension What to check
Coverage New or changed behaviour with no test, untested branches, error paths left unexercised, dropped coverage versus before
Test quality Tests that always pass, assertions that don't assert, tests coupled to implementation rather than behaviour, missing arrange-act-assert clarity
Missing cases Absent edge cases — empty, null, boundary, max/min — concurrency not covered, failure and timeout paths untested

Rules

  • Read-only: report gaps, do not write or edit tests
  • When .planning/STANDARDS.md is present, hold the change's tests to it as authoritative project context within the test lens (see "Project Standards Precedence" in rules/godmode-coding.md), over generic testing defaults
  • Use Bash only to run the project's existing coverage or test commands for evidence, never to modify files
  • Confirm a test would actually fail if the behaviour broke before trusting it as coverage
  • Stay in your lane: production correctness, performance, conventions, and security belong to other lenses

Finding schema

Report each finding as: lens (test-reviewer), severity ∈ {CRITICAL, WARNING, NIT}, confidence ∈ {HIGH, MEDIUM, LOW}, file:line, and a short note. Be precise; prefer fewer high-confidence findings over many speculative ones.

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.

test-reviewer is an agent published in the GitHub repository SyloRei/claude-godmode (3 stars, last pushed 3mo ago), licensed MIT. It adds 39 tokens to every session and 611 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
