Module marginal_gate 

Marginal Information Gate (#1308).

Checks whether a tool response provides enough new information to justify delivery to the model. Based on COMI’s MIG principle (arXiv 2602.01719): content should only be delivered if its information gain relative to what’s already in context exceeds a threshold.
