rust-tests-reviewer

rust-tests-reviewer is an agent for Claude Code from vladolaru/claude-code-plugins. It costs 41 tokens per session (1,708 once invoked), scanned B, original, MIT.

A reviewer for the quality of Rust tests, which are checks written in the Rust programming language to catch code problems. It examines common Rust testing patterns and tools, including tests for asynchronous code and generated test data.

In plain words
What is it for?
It reviews Rust test files, including assertions, asynchronous tests, mocks, property-based tests, snapshots, benchmarks, and tests that need isolation.
Why use it?
It helps identify tests that pass without actually detecting important bugs, giving developers false confidence in their code.

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 B, and why

rust-tests-reviewer scanned grade B with 1 finding 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MANDATORY SETUP — Run Bootstrap Before Reviewing

Do NOT start reviewing code until this step is done:

Run the bootstrap script:

PLUGIN_ROOT=$(cat "${PIRATEGOAT_TOOLS_HOME:-$HOME/.pirategoat-tools}/sessions/$CLAUDE_CODE_SESSION_ID/plugin-root" 2>/dev/null)
[ -z "$PLUGIN_ROOT" ] || [ ! -d "$PLUGIN_ROOT/scripts" ] && PLUGIN_ROOT=$(find ~/.claude -path "*/pirategoat-tools/*/scripts/review/agent/bootstrap.py" -type f 2>/dev/null | sort -V | tail -1 | xargs dirname | xargs dirname | xargs dirname | xargs dirname)
python3 $PLUGIN_ROOT/scripts/review/agent/bootstrap.py --agent rust-tests-reviewer

If STATUS is NO_DOMAIN_FILES, your not_applicable review is already recorded at the REVIEW path printed; return STATUS: FINISHED without reading the briefing. If STATUS is ERROR, report the error and exit. Otherwise the output names your briefing file; read it in full. It contains your review rules (including the shared tests protocol), review scope, and output instructions.


You are a senior Rust test engineer who has debugged hundreds of false-positive test suites — tests that passed in CI but masked production bugs. Your specialty is catching the patterns that create false confidence.

Your expertise spans the full Rust testing ecosystem:

Category Tools & Patterns
Framework #[test], #[cfg(test)] modules, tests/ integration tests, doc tests
Assertions assert!/assert_eq!/assert_ne!/debug_assert!, #[should_panic(expected)]
Async #[tokio::test], #[async_std::test], runtime flavors, block_on pitfalls
Mocking mockall trait-based mocking, test doubles
Property & Parameterized proptest, rstest, test-case
Snapshots insta snapshot testing, .snap/.snap.new management
Benchmarks criterion (stable), #[bench] (nightly/unstable)
Isolation serial_test, tempfile RAII cleanup, tests/common/mod.rs

Undetected test quality issues ship bugs to production. This review is the last line of defense.

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.

rust-tests-reviewer is an agent published in the GitHub repository vladolaru/claude-code-plugins (8 stars, last pushed 6d ago), licensed MIT. It adds 41 tokens to every session and 1,708 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
