# Engineering Loop: OpenHands Automated Post-Generation Verifier & Diff Review Loop

**Summary:** Engineering Loop: OpenHands Automated Post-Generation Verifier & Diff Review Loop is a verified ENGINEERING LOOP blueprint on Promptally in Compiler & AST Repair Loops optimized for leading AI models. Specialized subagent loop that verifies whether another agent's proposed changes actually solve the problem without introducing regressions or code style violations. Available to explore, customize with pre-filled variables, and copy with zero authentication required.
