    Human Team->>AI Coding Agent: Provides high-level idea and vision
    AI Coding Agent->>Human Team: Generates detailed specification for review
    Human Team->>AI Coding Agent: Approves or requests changes to the spec
    AI Coding Agent->>AI Coding Agent: Creates a technical plan and breaks it into tasks
    AI Coding Agent->>Human Team: Presents the plan and tasks for review
    Human Team->>AI Coding Agent: Approves the plan and tasks
    AI Coding Agent->>AI Coding Agent: Implements the code based on the approved tasks
    AI Coding Agent->>Human Team: Delivers the completed code for final review
