skilltest-pytest 0.1.0

pytest integration for skilltest: auto-collect *.skilltest.yaml cases as pytest tests, built on skilltest-sdk.

skilltest-pytest

A pytest plugin for skilltest: run AI-skill tests and natural-language evals as ordinary pytest tests, and mix in your own deterministic checks. Built on skilltest-sdk — the SDK's code API is re-exported here, so a pytest suite needs only this one dependency.

Two ways to use it

Auto-collected case files. Name a case something.skilltest.yaml and pytest runs it:

# greet.skilltest.yaml
skill: ./skills/greeter
input: "Greet Dr. Smith."
evals:
  - type: boolean
    criterion: "the reply greets Dr. Smith by name"

As code, for matrices and deterministic mix-ins:

from skilltest_pytest import run_skill

def test_greeter():
    report = run_skill("cases/greet.yaml", platforms=["claude-code"], models=["claude-opus-4-8"])
    assert report.passed, report.describe_failures()
    assert "Dr. Smith" in report.runs[0].transcript.assistant_text()

Configuration

The plugin shells out to the skilltest binary. Point it at one with the SKILLTEST_BIN env var (or bin=), the provider with SKILLTEST_PROVIDER (or provider=), and set defaults in pyproject.toml:

[tool.pytest.ini_options]
skilltest_provider = "oneharness"
skilltest_platforms = ["claude-code"]
skilltest_models = ["claude-opus-4-8"]
