Self-Harness: agents improve their own harnesses

What happened and what to do
Published on June 10, 2026, the paper explores agents that analyze their own failures and propose small changes to the harness, keeping changes that pass regression tests. It reports improved success rates on unseen Terminal-Bench-2.0 data with MiniMax, Qwen, and GLM.
In practice, a company could test this cycle to improve its agents’ prompts, tools, retries, and verification without fine-tuning. An implementation could log failures, propose controlled changes, and run them against a regression suite before releasing updates.
How the consultancy can help
Wendelmaques can diagnose where agents fail and assess whether this improvement cycle fits the case. The engagement can include a scoped implementation to log failures, test changes, and operate regression checks.
