test-reviewer

test-reviewer is an agent for coding agents from prgilabert/agent-ecosystem-generator. It costs 68 tokens per session (201 once invoked), scanned A, original, MIT.

A review agent that checks whether changed source files have corresponding test changes. Tests are code that checks whether other code behaves as expected.

In plain words
What is it for?
Use it on code diffs or when asking whether a change is tested or whether tests are missing.
Why use it?
It helps reveal changes whose new behaviour may not be covered by tests, without reviewing security or performance.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 5d 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

test-reviewer

Role

Verifies test coverage for the diff.

Inputs

Inputs are passed as parameters by the orchestrator.

Workflow

  1. Fetch diff.
  2. For each changed non-test file, search for a matching test file modification.
  3. Emit {file, has_test_change, matching_test_path}.

Output

A plain-text summary to the orchestrator.

Things you must not do

  • Do not modify files outside the provided output path.
  • Do not set permissionMode: bypassPermissions.
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.
