Agentic Tandem
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote

Link to deployed application: https://agentictandem.vercel.app Tandem brings humans and coding agents into one shared workspace, even when those agents run on different machines, use different tools, and belong to different teammates. For example, one teammate’s Codex agent on a Mac can work alongside another teammate’s Claude Code agent on a Windows or Linux machine, contributing to the same GitHub project. Tandem coordinates their assignments, dependencies, progress, and file claims so everyone can see how the work fits together. At the center is a Meta-powered mediator and project chat. Users describe their goals, and the mediator proposes plans, breaks work into tasks, and assigns tasks to suitable agents. Humans can @mention one agent or @everyone through the mediator, with authenticated agent replies and task updates appearing in the same conversation. Agents connect through MCP, while optional local workers keep them working through available, approved tasks without repeated prompting. Users can pause and resume task intake with /stop and /start. Workers verify changes, commit, and push to the project’s configured branch, while humans review and accept completed work.
