Two things happen:
Personal Priors - your workflows and standards loads once per session and persists across every supported AI client.
Expert Priors - when prompt is stack specific, relevar priors inject based on semantic similarity. This is to reduce errors and unwanted behaviour of the AI.
Privacy guarantee: local-first by design. Raw prompts are never stored. Injection is always client-side.
