A skill for running a project’s pytest tests, with optional parallel execution and coverage reporting. Pytest is a Python testing tool; coverage shows which code the tests exercise.

It helps run all or selected tests, use multiple CPU cores, generate terminal coverage, and produce coverage reports for CI.

It provides repeatable commands for quick checks, debugging, or fuller continuous-integration verification without manually assembling the test options.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00034	$0.00475
Opus 5	$0.00017	$0.00237
Sonnet 5	$0.00007	$0.00095
Haiku 4.5	$0.00003	$0.00047

Security

Grade A, and why

run-tests 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/test.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Run Tests

Run the project's pytest suite with optional parallelism (pytest-xdist) and coverage. Coverage targets are read from pyproject.toml's [tool.coverage.run] section, so the same script works in any sibling repo without modification.

Usage

# Default: parallel + verbose (recommended)
bash .claude/skills/run-tests/scripts/test.sh -p

# Quick check: parallel + quiet
bash .claude/skills/run-tests/scripts/test.sh -p -q

# Full CI mode: parallel + coverage + xml report
bash .claude/skills/run-tests/scripts/test.sh --ci

# Specific test file
bash .claude/skills/run-tests/scripts/test.sh -p tests/test_socket_server.py

# Without parallelism (for debugging test ordering issues)
bash .claude/skills/run-tests/scripts/test.sh tests/test_rooms.py

# With coverage
bash .claude/skills/run-tests/scripts/test.sh -p -c

Options

Flag	Short	Description
`--parallel`	`-p`	Run with `-n auto` (pytest-xdist, uses all CPU cores)
`--coverage`	`-c`	Enable coverage reporting to terminal
`--ci`		Full CI mode: parallel + coverage + XML report + verbose
`--quick`	`-q`	Quiet output (no verbose, no coverage)

Extra arguments are passed through to pytest (e.g., -x for stop-on-first-failure, -k "pattern" for filtering).

When to Use Which Mode

After code changes: bash test.sh -p — fast parallel run, verbose output
Quick sanity check: bash test.sh -p -q — minimal output
Before PR / release: bash test.sh --ci — matches CI exactly
Debugging flaky test: bash test.sh tests/test_flaky.py — sequential, single file

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

run-tests is a skill published in the GitHub repository agentculture/culture-tools (2 stars, last pushed 2d ago), licensed Apache-2.0. It adds 34 tokens to every session and 475 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to run-tests, differing in 0 lines, and is treated as a copy.
