Is the information coming from queries to the knowlege api or from the context that had been built up? If it's from the context that's been built-up, then thats expected

When I tested the same scenario again, I was not getting the information from the deleted knowledge files when tool call was made to knowledgeRetrieval tool.
When I see the behavior mentioned in the issue , it is from the Knowledge Retrieval Context
