Twenty organizations have jointly released the "Self-Discipline Convention on Agent Development," proposing eight self-discipline measures. These measures cover improving the agent trust system, building interconnected infrastructure, enhancing interoperability, strengthening security protection capabilities, improving governance mechanisms, protecting user rights, empowering all industries, and promoting inclusive sharing of technology. The convention represents an important step toward standardized development in the agent industry, helping to build consensus, promote industry self-discipline, enhance mutual trust, interconnection, and interoperability among agents, and guide standardized application and innovative development. The initiating organizations will take the lead in implementing the content of the convention, proactively accept supervision, and welcome various entities in the ecosystem to participate in the construction of the convention, jointly creating an open, trustworthy, secure, and inclusive agent ecosystem.
