  "title": "TAP: Efficient Long-Horizon Agent Pruning via Trajectory-Anchored Recovery",
  "summary": "TAP replaces one-shot importance-based pruning plus offline or full-trajectory distillation with iterative gradient-based channel re-scoring coupled to recovery, using a frozen dense teacher that anchors trajectories while the pruned student generates each response. It costs a pruning-and-recovery training pipeline: a frozen 7B teacher in memory, gradient computation for re-scoring, and RL-style trajectory rollouts, which is a substantial engineering and compute burden beyond simple post-hoc pruning. It can fail when applied to non-RL agents or tasks whose reward signals differ from ALFWorld/WebShop, and the WebShop retention of 88.0% shows meaningful task-dependent quality loss at 60% channel removal.",
  "rationale": "The method requires a full pruning-plus-on-policy-recovery training run with a frozen teacher, which exceeds a 24 GB GPU budget unless the authors release pruned checkpoints, so it is worth tracking rather than implementing now.",
