Opera tracks whether coding-agent feedback actually resolves problems

huggingface.co by Kai Mei et al. Editor score 8/10

Opera audits critic feedback against visible evidence, then follows the agent's actions to distinguish compliance from resolution; it raises resolve rates by up to 12.4, 15.0 and 8.9 percentage points on three benchmarks. This offers a concrete way to improve long-horizon agent critique.

What: Opera is a verbal critic that keeps corrections as persistent notes until it determines whether the diagnosed issue is resolved.
Method: Periodic or event-driven reviews diagnose with typed operators, audit feedback against visible evidence, and track later actions.
Why it matters: Opera-guided rollouts improved Qwen3.5-9B's held-out SWE-Bench Pro resolve rate by 10.2 points without a critic at inference.

Opera reviews work, audits and delivers feedback, then tracks whether later actions resolve the issue. Sketched from the article's own text.
