Parallel Processing
Use tmux for background tasks, Agent Teams for multi-instance parallel work.
Agent Teams (Preferred for Multi-Task Work)
For 2+ independent tasks that each need a full Claude session:
Create an Agent Team with one teammate per task.
Each teammate gets a spawn prompt with their task details.
Teammates can discuss findings across domains.
Use /delegate-tasks to automate team creation for task-master tasks.
Recommended: Use Subagents for Context Efficiency
For simple parallel commands, launch multiple tmux-runner subagents in parallel:
# Launch all three in parallel (single message with multiple Task calls)
Task(subagent_type="tmux-runner", description="Run tests",
prompt="Run 'npm test' and return results", model="haiku")
Task(subagent_type="tmux-runner", description="Run lint",
prompt="Run 'npm run lint' and return results", model="haiku")
Task(subagent_type="tmux-runner", description="Run build",
prompt="Run 'npm run build' and return results", model="haiku")
This saves context in the main conversation - you only see the results, not all the intermediate tmux operations.
Pattern: Background Task (Direct)
For long-running servers you need to monitor:
# Start background task
window_id = tmux_new_window(command="npm run dev", name="dev-server")
# Continue working...
# Check later
output = tmux_capture(target=window_id, lines=50)
# Clean up
tmux_kill(target=window_id)
Pattern: With Notification
window_id = tmux_new_window(command="npm run build", name="build")
status = tmux_wait_idle(target=window_id, timeout=300)
notify(title="Build Complete", message=f"Status: {status}")
Pattern: Multiple Parallel (Direct)
When you need to manage windows yourself:
test_win = tmux_new_window(command="npm test", name="tests")
lint_win = tmux_new_window(command="npm run lint", name="lint")
build_win = tmux_new_window(command="npm run build", name="build")
for w in [test_win, lint_win, build_win]:
tmux_wait_idle(target=w, timeout=120)
