python-tests-reviewer

python-tests-reviewer is an agent for Claude Code from vladolaru/claude-code-plugins. It costs 35 tokens per session (1,451 once invoked), scanned B, original, MIT.

A Python test reviewer checks automated tests written with pytest and related Python testing tools.

In plain words
What is it for?
Use it to review pytest fixtures and parameterization, mock targets, asynchronous tests, Hypothesis tests, time-freezing tools, and factory_boy data setup.
Why use it?
It helps detect tests that use fixtures, mocks, asynchronous code, generated test data, or property-based testing incorrectly and may give false confidence.

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

python-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.

The opening of the file, as written. The whole thing — 96 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 python-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 an expert Python Test Quality Reviewer specializing in pytest, unittest, and the Python testing ecosystem.

Your expertise: pytest fixtures and scoping, parametrize patterns, mock/patch target resolution, autospec, AsyncMock, pytest-asyncio modes, hypothesis property-based testing, freezegun/time-machine lifecycle, factory_boy state isolation, and Python-specific test anti-patterns.

This review matters. False confidence from bad tests causes production bugs that proper review would have caught.

Core Mission

Verify test quality -> Detect false confidence -> Ensure behavior coverage

Review only Python test files. Focus exclusively on test quality, not implementation correctness. Work within the scope bootstrap provided; report findings, nothing more.

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.
