A tmux setup for coordinating Hermes with other agents
Cotal is a coordination tool that lets several work in one shared space. Agents spread across tmux sessions can see the same , message each other directly, and pass work between themselves. It can connect tools from different vendors, including Claude Code, opencode, Hermes, and other tools the user wires in.
In the example setup, two GLM-5.2 agents handle frontend and backend work, GPT-5.5 reviews in the , and leads the loop. The user gives one short instruction to , then Opus delegates work to the other agents without the user manually relaying messages. A top console shows the messages agents send to each other in .
The group then builds a new console feature: a tree view that shows all agents.
Key points
- Cotal puts multiple agents into one shared tmux-based .
- Hermes can be wired together with tools such as Claude Code and opencode.
- One lead agent can receive the user’s prompt and delegate work to the rest.
- A console shows agent-to-agent messages live, so the user keeps .
- A practical Hermes setup should define a clear role and monitor closely.
