    "body_text": "Across several benchmarks and models, the authors report that the persistent wiki improved on prior skill-evolution methods and usually beat no-skill baselines. Evolved skills transferred across model families, and smaller models with skills sometimes outperformed substantially larger models without them; ablations attributed part of the gain to accumulated knowledge rather than the executable skill alone.",
