tools-only Technical Design: launcher-mode-verification
Metadata
- Feature: launcher-mode-verification
- Status: APPROVED
- Created: 2026-01-31
1. Overview
Enhance rush output to show human-friendly launcher mode and worker count at start and in completion summary.
2. Changes
2.1 zerg/commands/rush.py (~lines 159-160, 188-196)
Start output — replace:
launcher_name = type(orchestrator.launcher).__name__
console.print(f"Launcher: [bold]{launcher_name}[/bold]")
With:
launcher_name = type(orchestrator.launcher).__name__
mode_label = "container (Docker)" if "Container" in launcher_name else "subprocess"
console.print(f"Launcher mode: [bold]{mode_label}[/bold]")
console.print(f"Workers: [bold]{workers}[/bold]")
Completion output — add mode to summary:
if status["is_complete"]:
console.print(f"\n[bold green]✓ All tasks complete![/bold green] (mode: {mode_label})")
2.2 Tests — tests/unit/test_rush_cmd.py
Update any assertions that check for the old "Launcher:" output format.
