Turn Claude Code, Codex and OpenCode into a team.
Task management is at the core of harnsy. It gives agents a shared place to own tasks, coordinate work and submit results — and gives you a place to make the important decisions and review what they’ve done.
Talk to one lead agent. It brings in the roles it needs, assigns tasks, and returns questions and finished work. Agents talk to each other directly, so you don’t have to copy messages between chats.
- Tasks connect everything. Each task carries the request, owner, acceptance criteria, progress and results.
- You make the key decisions. Set priorities, answer questions that block the team, and accept finished work or return it for changes.
- One lead to talk to. The lead assigns work and coordinates the team.
- Different models, one team. Use Claude Code, Codex and OpenCode together.
- Roles that outlast sessions. When context runs low, a fresh agent takes over the same role with a written handover.
- One dashboard. Follow tasks, inspect results, read conversations and open any agent’s terminal.
