tmux Subagent Orchestration

Run Devin CLI subagents in parallel by giving each one its own tmux window. The parent agent delegates a task, waits for a completion signal, reads the subagent's output file, and closes the window.

When to Use

• Fan out independent research, refactors, or test runs across several agents.
• Keep a long-running Devin session alive in the background while continuing other work.
• Coordinate multiple agents that each own a distinct task/context.

Setup (do once per session)

Before any tmux operation, resolve two values and reuse them:

1. TMUX=$(which tmux) - absolute path to the tmux binary.
2. SESSION=$("$TMUX" display-message -p '#S') - current session name.
