Self-Evolving Agent Harness

Harness self-evolution revises an agent's software scaffolding, including prompts, memory, workflows, and executable components, while keeping model weights fixed.

Key points

  • We formalize a feedback-driven process in which accepted revisions persist across runs.
  • We characterize search through evolutionary optimization and examine its reliability through continual PAC-learning.
  • We examine how persistent harness revisions affect knowledge sharing and organizational workflows, with implications for scientific reliability, physical safety, and institutional accountability.
  • Cases from prior work illustrate model--harness co-design, distributed execution, and plugin reuse.
