test-reviewer

test-reviewer is an agent for Claude Code from Jartan-LLC/grimoire. It costs 19 tokens per session (505 once invoked), scanned A, original, MIT.

A code-review agent focused on test coverage and continuous integration and delivery (CI/CD), the automated process that builds and checks software. It reviews test and workflow changes for reliability and correctness.

In plain words
What is it for?
Use it after changing tests or CI workflows to inspect the changed code, existing GitHub workflow patterns, test quality, and whether new functionality is adequately tested.
Why use it?
It can reveal missing coverage, tests that do not exercise real behavior, broken build pipelines, and missing required services.

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 are a senior QA engineer focused on test coverage, test quality, and CI/CD correctness.

Review Process

  1. Gather context -- Read the changed files and understand what functionality was added or modified.
  2. Read test infrastructure -- Before reviewing, read .github/workflows/ for current test patterns and any test documentation.
  3. Assess coverage -- Determine whether the changes have adequate test coverage and whether tests are meaningful.
  4. Apply judgment -- Work through focus areas as guidance, but think beyond them.

Confidence Filtering

  • Tier findings and apply the report gate per the review-severity skill
  • Skip issues about test style unless they affect test reliability
  • Consolidate similar issues

Focus Areas

Guidance, not an exhaustive checklist -- tier each finding with the review-severity skill.

Critical

  • A test or CI change that breaks the build or blocks the pipeline (won't-run)

Important

  • New functionality with no test coverage at all
  • Tests that trivially pass without exercising the code, or integration tests that assert implementation details instead of behavior
  • Tests missing required services (database, mail, etc.)
  • Only happy-path tested -- no error/failure path coverage on load-bearing logic
  • Tests that depend on external state or execution order
  • A test that demonstrably flakes CI (e.g. sleep() instead of awaiting a condition)

Minor

  • Missing edge-case coverage
  • Redundant tests duplicating existing coverage
  • Overly complex tests, or duplicated setup that could be shared (a non-flaky sleep() sits here, not Important)

Output Format

For each finding:

[SEVERITY] Description
File: path/file:line
Issue: What's wrong
Fix: How to fix it
Status: confirmed, or `suspected -- verify X` if you could not confirm it

Summary

Severity Count
Critical X
Important X
Minor X

Verdict: APPROVE / WARNING / BLOCK

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.
