Orchestrate Multiple Claude Instances

One Claude is good. Three running in parallel is a superpower.

tmux Setup

#!/bin/bash
# launch-claudes.sh
tmux new-session -d -s claude-work

# Pane 1: Main feature work
tmux send-keys "cd $(pwd) && claude" Enter

# Pane 2: Tests
tmux split-window -h
tmux send-keys "cd $(pwd) && claude" Enter

# Pane 3: Research/review
tmux split-window -v
tmux send-keys "cd $(pwd) && claude" Enter

tmux attach-session -t claude-work

Worktree + tmux Combo

git worktree add ../project-feature main
git worktree add ../project-tests main

tmux new-session -d -s work
tmux send-keys "cd ../project-feature && claude" Enter
tmux split-window -h
tmux send-keys "cd ../project-tests && claude" Enter
tmux attach

Each Claude has its own context window and works independently. One builds the feature, one writes tests, one reviews, all simultaneously.

Scripted Orchestration

# Run multiple analyses in parallel
echo "Review auth module" | claude -p > auth-review.md &
echo "Review payment module" | claude -p > payment-review.md &
echo "Review user module" | claude -p > user-review.md &
wait
cat *-review.md | claude -p "Summarize these reviews into a single report"
