To see how this works in practice, consider a concrete enterprise use case: a customer success agent that needs to answer, “Why was this customer promised a different renewal price, and should we honor it?”

The answer may require reconstructing a causal chain across a support conversation, a sales exception, a contract clause, a billing-system update, and a later internal note. Traditional similarity-based RAG might retrieve the most recent billing document or the most semantically similar support ticket, but fail to connect the causal chain.

With MRAgent’s active reconstruction, the agent can extract cues like the customer’s name, follow associative tags to the original support ticket, retrieve the sales exception, and link it to the billing update. It navigates these semantic relationships, prunes irrelevant branches, and iteratively stops once it has enough evidence to answer the query.
