Parallel Engine

PowerShell multi-session parallel execution engine — run independent tasks simultaneously across isolated git worktrees with automatic merge and verification.

Features

• Multi-Session Dispatch — Spawns parallel PowerShell sessions for truly concurrent task execution
• Git Worktree Isolation — Each task runs in its own worktree to prevent file conflicts
• Auto-Merge — Merges completed worktree branches back to main with conflict detection
• Progress Tracking — Real-time status dashboard showing each parallel task's progress
• Verification Loop — Runs automated tests after merge to ensure combined changes work together

Quick Start

claude skill install parallel-engine

Usage

# Run three independent tasks in parallel
/parallel-engine --tasks "fix auth bug" "add user avatar" "update API docs"

# Execute a plan with automatic parallelization
/parallel-engine --plan implementation-plan.md

How It Works

Analyzes task dependencies to identify which can run concurrently. Creates isolated git worktrees for each task and dispatches separate PowerShell sessions. Monitors all sessions for completion, then merges results back to the main branch. Runs verification tests to ensure parallel changes integrate cleanly.

Compatibility

Works with Claude Code, Codex, Gemini CLI, Cursor, Windsurf, and Aider.
