Language agents typically lean on external harnesses for more than just tools and information. According to a new arXiv paper, these harnesses also provide control decisions about what to investigate and whether to revise, effectively steering the agent's behavior from the outside.
The paper introduces "harness annealing," a concept aimed at reducing that dependency. Instead of relying on the harness to make every high-level choice, the agent would learn to take over those decisions over time.
Because the abstract is truncated, the full method and experimental results are not available from the source alone. Still, the framing points to a shift toward more autonomous agents that retain the benefits of external structure without being fully controlled by it.
