skilltest-sdk 0.1.1

Python SDK for the skilltest CLI: run AI-skill tests and natural-language evals from Python, with a typed report contract.

skilltest-sdk

The Python SDK for the skilltest CLI. A thin, typed wrapper and nothing else: it runs the CLI as a subprocess and parses the stable --format json contract into Pydantic models. Test-framework integrations build on it — use skilltest-pytest if you want pytest collection; use this package directly from any other Python code.

from skilltest_sdk import run_skill, validate_skill

report = run_skill("cases/greet.yaml")
assert report.passed, report.describe_failures()
# Mix in deterministic checks on the transcript:
assert "Dr. Smith" in report.runs[0].transcript.assistant_text()

result = validate_skill("skills/greeter")
assert result.valid

The skilltest binary is resolved from the bin= argument, the SKILLTEST_BIN env var, or PATH; a provider override comes from provider= or SKILLTEST_PROVIDER. A failing eval is reported (report.passed is false), not raised; bad input raises SkilltestUsageError (CLI exit 2) and provider problems raise SkilltestProviderError (exit 3).

The Pydantic models are generated from schemas/report.schema.json / schemas/validation.schema.json — themselves generated from the CLI's own types — via just gen-contract, and a drift gate in CI fails if anything is stale, so the models cannot diverge from the binary.
