Background & analysis
On October 21, 2026, DEV Community published a first-person account from a developer who runs multiple Claude Code sessions in tmux every day and shared the setup behind it. In his configuration, each git worktree gets its own session, supported by a spawner script, send-keys so scripts can drive the agents, and a hook that signals when a task finishes. Detaching and reattaching lets a job on a remote box keep running.
The post cites Anthropic's documentation, which recommends starting a team of Claude Code agents at 3 to 5 and states that three focused teammates often outperform five scattered ones. The author notes that most posts claiming to run 12 agents in parallel skip that line, and he points to a threshold beyond which adding more agents makes things slower, though the report does not give a specific number.
The account also notes that tmux is free, has existed since 2007, and covers what parallel agents need. Beyond the configuration approach and the documentation quotes, the material does not describe how the setup performed in practice or any further developments.

How is heat calculated?About the methodHide
Heat counts how many independent sources covered a story in the last 48 hours: one source counts once no matter how many posts it published, decaying with a 24-hour half-life. What ranks first is what many people are talking about.
