• Orchestrator Agent
• Frontend Agent
• Backend Agent
• Database Agent
• QA Agent
• Security Agent
• DevOps Agent
• Documentation Agent
• UX/UI Agent
• Agent Configuration

Each agent in MAF is designed with specific expertise and responsibilities:

The Orchestrator is the central coordinator that breaks down high-level requests into specific tasks and manages the overall workflow.

• Task Decomposition: Breaks features into manageable subtasks
• Dependency Management: Ensures tasks are completed in order
• Agent Assignment: Routes tasks to appropriate specialists
• Progress Monitoring: Tracks task status and completion
• Failure Recovery: Handles retries and fallback strategies

User Request: "Add user authentication"
Orchestrator Actions:
  1. Create database schema task → Database Agent
  2. Create API endpoints task → Backend Agent  
  3. Create login UI task → Frontend Agent
  4. Create auth tests task → QA Agent
  5. Security review task → Security Agent
