SkillMem stores procedures as compact external memories for multi-agent systems, rather than repeatedly supplying their text. A shared reader uses each agent’s role and hidden state to access memory; the backbone stays frozen while the memory and reader learn the procedure’s behavioral effects. On GPQA-Diamond, Qwen3-4B reaches 35.63% accuracy versus 17.97% for LatentMAS, but gains are not consistent across model sizes.
