Tokens, turns and time describe resource use, not a dollar price.
A test case the skill fixed. Same model, same prompt, with and without the skill.
Write a pytest fixture and test function using `httpx.AsyncClient` and `ASGITransport` to test an async Python web application endpoint asynchronously without spinning up a live server.
| Checked | Without skill | With skill |
|---|---|---|
| Uses httpx.AsyncClient with transport=ASGITransport(app=app) | Passed | Passed |
| Marks the test function with @pytest.mark.asyncio | Missed | Passed |
