What it does

The Decision helper applies confidence cutoffs. Text checks default to typesafe/jev-1.13 through OpenRouter, while visual checks can use Clef. This is separate from chat-based test repair. The provider receives page text or images sent by the test runner.

How you can use it

Set up the Decision helper with an OpenRouter key and describe what the page should do. A meaning-based check can tell whether a message explains an error when matching exact text would miss it. Keep ordinary assertions for exact facts, and account for page content leaving the runner for the provider.
