Definition — Contextual Data Access means an AI assistant or agent retrieves the records that matter for the person asking, such as their account, location, or history, and answers from those rather than from general knowledge. In Halley AI™, the assistant can reach only the sources it has been granted.
The assistant pulls the records that matter for this question (account, location, history) instead of answering from a generic model.
A general answer to "How many credits do I have?" is no use to the person asking. Contextual Data Access lets the assistant look up that person's own record at the moment they ask, and answer from it.
It is the difference between quoting the rules and answering the person. In the nurse advancement program Halley supports, the assistant connects to the hospital's learning-management and HR systems, so a nurse who asks how many credits they have toward the next clinical level gets their own current count.
