how will you initiate the agent? If you use a webhook/app that is hit then you should be able to 1. upload any KB item(s), 2. create a transient agent with context even inside the PROMPT may not even need dynamic variables, 3. then it will work just fine. Are you holding the content in the KB permanently or will you need to remove after the session? if so this would be step 4. clear any uploaded content from KB. You will def need to use coding or no-code solution on this one.
