tl;dr: providers don't seem to be sent test context when used for asserts
Hi, I'm trying to use promptfoo to evaluate some agentic workflows. I have a custom python provider that does some environment setup. I need to be able to pass information from the provider completing the prompt to the provider when it is evaluating an llm-rubric assert that doesn't belong in the prompt response. The context seems to always be empty when the provider is used for asserts. Is this working as intended and if so, is there an intended way to pass this information to the assert provider?
