• **File operations** with comprehensive project analysis
• **Code generation** and refactoring with enterprise patterns
• **Debugging** and error analysis
• **CI/CD integration** via headless mode
• **MCP plugin support** for extensibility

Sessions

Droid sessions are stored in:

~/.config/droid/sessions/

Session Management

# List sessions
amux sessions droid

# Read session
amux sessions droid read <session-id>

# Resume session
amux run droid --session-id <session-id>

# Fork session
amux sessions droid fork <session-id> --name "feature-branch"

MCP Plugins

Droid supports MCP (Model Context Protocol) servers for enhanced functionality:

# List available plugins
amux plugins list droid

# Install MCP server
amux plugins install droid <mcp-server>

# List installed plugins
amux plugins list droid --installed

Configuration

Droid configuration is stored in:

~/.config/droid/config.json

Project-specific Configuration

Create .droid/config.json in your project root:

{
  "defaultModel": "claude-sonnet",
  "autoApprove": false,
  "maxParallelTasks": 5,
  "workflowPresets": {
    "code-review": {
      "systemPrompt": "Focus on security, performance, and maintainability",
      "model": "gpt-5-turbo"
    }
  }
}

Enterprise Features

Headless Mode

Perfect for CI/CD pipelines and automation:

# One-shot execution
droid exec --prompt "Run all tests and fix failures" --headless

# Via agent-mux
amux run droid --prompt "Generate deployment scripts" --headless

Parallel Execution

Droid can handle multiple tasks simultaneously:

amux run droid --prompt "Optimize performance while fixing security issues"

Workflow Automation

Create complex development workflows:

amux run droid --prompt "
1. Analyze the codebase for technical debt
2. Create refactoring plan
3. Implement high-priority improvements
4. Generate comprehensive tests
5. Update documentation
"

Error Handling

Common error codes and solutions:

Troubleshooting

Authentication Issues

# Check authentication status
droid whoami

# Re-authenticate
droid auth logout
droid auth login

Performance Issues

# Check system status
droid status

# Clear cache
droid cache clear

Session Issues

# Verify session directory
ls ~/.config/droid/sessions/

# Check session file integrity
amux sessions droid read <session-id> --validate

Best Practices

1. **Use specific models** for different tasks: - gpt-5-turbo: General coding and architecture - claude-sonnet: Code review and documentation - gemini-flash: Quick prototyping and testing

2. **Leverage headless mode** for automation: ``bash amux run droid --prompt "Daily code quality check" --headless ``

3. **Configure project-specific settings** in .droid/config.json

4. **Use auto-approve carefully** - only in trusted environments: ``bash amux run droid --tool-approval-mode yolo --prompt "Format all files" ``

5. **Monitor costs** with cost tracking: ``bash amux run droid --prompt "Complex refactoring task" | amux cost ``
