From Agent Computers to Team Delivery: QM and CubePlex
QM (Quartermaster) is YC's open-source, self-hosted multiplayer agent harness. It places people, Slack channels, groups, and projects in scopes, using each scope as an agent work environment and permission boundary. CubePlex is an open-source Agent Workspace for teams: it first defines a long-lived Workspace Agent, then lets Web, Slack, Discord, Microsoft Teams, Feishu/Lark, DingTalk, WeCom, and other entry points determine the conversation, identity, and execution boundary for a run.
The distinction changes everyday use. One model is suited to operating many independent agent computers under a company's permission and runtime system. The other is suited to keeping one team agent consistent across entry points without mixing private conversations, credentials, or execution environments.
