🎯 Core Features

🔐 Unified Authentication & API Management

# Login once, use everywhere
dev login

# All your API keys are synced and encrypted locally
# - OpenAI/Codex API keys
# - Anthropic/Claude API keys  
# - Google/Gemini API keys
# - Auto-passthrough to all tools

🤖 Run Any AI Tool

# Claude - Advanced reasoning and coding
dev run claude "refactor this authentication system"

# Aider - Git-aware pair programming
dev run aider "add test coverage" --auto-commit

# OpenHands - Autonomous software engineering
dev run openhands "implement user management" --worktree

# Codex - Code generation
dev run codex "generate a REST API client"

# Gemini - Multimodal AI
dev run gemini "analyze this architecture diagram"

⚡ Async Long-Running Tasks

# Start task in background (auto-quits after 5min idle)
dev run claude "migrate database to PostgreSQL" --async
# Output: Job ID: abc123...

# Check status
dev status abc123

# Keep alive and send more instructions
dev input abc123 "also add connection pooling"

🌳 Parallel Development with Git Worktrees

# Spawn multiple AI agents working in parallel
dev run claude "implement auth" --worktree
dev run aider "add tests" --worktree  
dev run openhands "write docs" --worktree

# Each runs in its own branch and directory
dev worktree list

🔄 Compare AI Tools

# See how different AIs approach the same problem
dev compare "optimize this database query"

# Output shows results from all tools side-by-side
