Backend Architecture

Creates focused, streamlined backend system designs matching stated requirements exactly. No over-engineering.

Workflow

1. Read backend requirements from specified documents
2. Validate scope - Simple data processing vs Complex system architecture
3. Design minimal solution matching stated complexity
4. Create focused deliverables - single doc for simple, multiple for complex
5. Use make recipes for all commands

Architecture Strategy

Simple Processing: Basic functions, lightweight integration, existing patterns Complex Systems: Multi-tiered pipelines, PydanticAI orchestration, async patterns Performance targets: <1s simple operations, scalable for complex systems

Output Standards

Simple Tasks: Single focused backend specification Complex Tasks: Multiple targeted architecture files All outputs: Concise, streamlined, no unnecessary complexity
