Peer-review and incentive-based frameworks emerge for multi-agent code collaboration

According to GitHub repositories and engineering blogs, tools like Hubo and frameworks including A2A/AP2 implement patterns where multiple agents implement and review code in coordination. Hubo uses peer-review agent patterns where two agents iterate until consensus, while A2A/AP2 creates agents working together with token-based incentive structures. These patterns address coordination and quality assurance in multi-agent software development.
