The AI Builder learns reusable meta-skills from development executions, then uses them to construct task-specific harnesses for a fixed AI Target. It supplies instructions, resources, and executable support without changing model weights. Across six model-benchmark settings, full-bank meta-skills averaged 65.31%, 8.95 pp above no-skill construction and 12.02 pp above direct delivery; these gains measure Target performance under fixed execution limits.
