Engineering Team Crew

Overview

Layer 4 Collaborate on the Mental Model. Engineering Team chains an engineering lead, backend engineer, frontend engineer, and test engineer. Requirements become one self-contained Python module, a Gradio app.py, and matching unit tests.

Behavior

• Prompt Chaining. design_task → code_task → frontend_task / test_task (both take code context). See Building effective agents.
• Lead designs first. Signatures and module shape land in markdown before implementation.
• One module backend. Backend stays a single file named {module_name}; backend and test agents may run code in Docker-safe mode.
• Gradio as demo UI. Frontend engineer writes app.py beside the backend module.
