1. Meta Adds a Second ‘Memory’ Agent to Keep Long-Running Agents on Track

Meta. Meta AI researchers proposed a dual-agent design that runs a dedicated memory agent alongside the action agent, tracking execution history and selectively injecting reminders so long tasks stop drifting or repeating failed steps. The approach lifted Terminal-Bench 2.0 from 38% to 46% and tau2-Bench from 55% to 62%, beating fixed-recall baselines and existing memory layers such as Mem0. The team argues that deciding when to surface memory matters as much as storing it, and it published the project’s code on GitHub. Source
